Install the split system yourself. How to install a split air conditioner yourself

After the onset of spring, it becomes necessary to cool the apartment. There are several ways to do this. One of them is to open the window. But in this case, you will most likely not fall asleep at night due to the noise of traffic and the buzzing of mosquitoes over your ear. So it’s better to choose the second method - buy a split system. But we all know that installation costs are often unreasonably high. So let's look at how to install an air conditioner yourself. This is not easy to do, but it is quite possible.

Some general information

We are faced with a serious, but quite feasible task. Almost any man who has done repairs at least several times in his life will be able to cope with the installation. Yes, and a beginner, with the right approach, will be able to install an air conditioner at home. I would like to immediately note that all this is necessary for significant cost savings. Installation, depending on the type and power of the split system, can cost from 4,000 to 10,000 rubles, and this, you see, is a lot. We will not talk again about how the air conditioner works; the same applies to its characteristics. Now we are exclusively interested in installation.

The first thing you have to decide on is the installation location. If you bought a window air conditioner, then its placement area is limited to window openings and vents. If you want to install it away from the window, you will need a fairly long outlet pipe (corrugation). You will have to pay a lot for each meter. We'll talk about this later, but a little later. As for a conventional, wall-mounted or sub-ceiling split system, here you need to follow a few simple rules: the distance to the ceiling should be more than 100 millimeters, there should be no objects (cabinets, etc.) 2 meters in front of the air conditioner, this necessary for normal air circulation and temperature maintenance. As for the external unit, it needs to be installed slightly above the window level. It is mounted on special brackets at a distance of approximately 20 centimeters from the wall. Well, now let's talk about how to install an air conditioner yourself and what tools you will need for this. The list will be quite large.

Finding the right tool

In order for our split system to be installed efficiently and reliably, we need to do the job correctly at all stages. To do this you will have to use quite a lot of equipment. First you will need a hammer drill with a set of chisels. We will have to drill a hole in the load-bearing (main) wall with a diameter of 100 millimeters. In addition, there must be a reinforcement detector. Of course, if you hit iron with a hammer drill, then all the work will have to be done again, and this is not very good both for the wall and for you. We will also need a pipe cutter. A simple household model will be enough. Do not forget that it is simply impossible to properly install an air conditioner in an apartment without having a device for cutting pipes. This is due to the fact that the compressor is very sensitive to any foreign objects. Copper shavings that remain in the gap of the hacksaw field will quickly disable it.

If you are planning to flare pipes using improvised means, then this is a very bad idea. This way you will not be able to achieve 100% tightness, which is necessary. For this simple reason, you need to buy a special flaring kit. It is also advisable to have a reamer on hand - a device for stripping cut copper pipe. A file is not suitable as it leaves crumbs. We will also need a regular pump, which can be used to easily check the tightness of the entire system. A vacuum pump is necessary to remove moisture from the system and evacuate it. It is advisable to have a pressure gauge and a simple tester on hand for working with electrical circuits. How to install an air conditioner in an apartment yourself? Let's talk about this in more detail now.

Step 1: Purchasing, cutting, scraping and flaring copper tubes

One of the most important points is the purchase of tubes for circulating refrigerant. It is highly recommended that you purchase the whole set, you will likely have some left over, but it is better than running out of a piece. As noted above, a cut piece is not a good thing, so try to do as little work as possible with the pipe cutter. As for the rolling, it should be factory-made in the coil. Pay attention to the absence of defects on the copper tubes (abrasions, cracks, chips, etc.), as this can lead to depressurization of the system during operation. If the length of the pipes is quite long, then it will be possible to lower the outdoor unit slightly.

As for cutting, everything is quite simple. The most important thing is to make an even cut along the entire diameter. As for flaring, it is better to practice first, since it is unlikely that you will succeed the first time. To do this, buy a small piece of copper pipe on which you will train. The inner surface should be smooth, and the flaring itself should be uniform and symmetrical. Cracks and distortions are simply unacceptable. After you have done everything, you can begin the actual installation. In order to install an air conditioner in an apartment and do it correctly, you need to start with the outdoor unit. However, there are several nuances and important points here, for example, the Ministry of Health does not recommend carrying out installation yourself on the second and upper floors.

How to install the outdoor unit?

If you do not live on the ground floor, experts advise installing it on a balcony or loggia. In this case, you are unlikely to fall, and it will be much easier to maintain the unit in the future. Please note that the balcony canopy should protect the air conditioner from sunlight; of course, this is not necessary, but it is desirable. We will use small or medium brackets, no more than 20 centimeters. As you know, it is necessary to install on the south side. As practice shows, installing the unit yourself is quite difficult, so invite a friend or neighbor to help you. The only inconvenience that you may experience during installation is removing the balcony glazing, if any. To install the air conditioner yourself, you will need shallow brackets. We will attach them to the frame.

Pay attention to the bottom of the frame; this is where the root parts of all existing brackets will have to be driven. If you can bend the root parts down, then it is quite possible to do without compromising the integrity of the balcony cladding. Don't forget that secure fastening is very important. Agree, an outdoor unit falling from the second floor can injure or even kill a person. To perform correct installation, you must use a level. Horizontal position will ensure proper operation of the compressor. Take a look at the product data sheet; modern models have their own standards. All indents must be observed.

Indoor unit and electrics

First, let's talk about places where it is strictly forbidden to install a split system. In close proximity to heating radiators, as well as near other heat sources (convector, etc.). In addition, the indoor unit should not be exposed to electrical noise from microwave ovens, powered tools, etc. Curtains should not interfere with normal air circulation. From this we can draw a simple conclusion that you cannot install an air conditioner in the kitchen, since it has its own ventilation. You probably ask: “Where is the best place to install an air conditioner?” A living room or bedroom is ideal for this. Of course, you can choose any other place, as long as there are no obstacles.

As for the electrical wiring, there is nothing complicated here. Currently, the simplest models of air conditioners have a power of 1.3 kW. For normal operation of such a device, you will need additional wiring with a cable cross-section of at least 1.5 square meters. mm, you can take it with a small margin. We will also install automatic shutdown, for example, like on a washing machine or boiler. When you get to work with the shield, connect the yellow wire to zero (neutral). Do not forget that in some cases non-standard wire colors are used, so you must enter your own phase and zero designations. After we have figured out where to install the air conditioner and done the electrical work, we move on to the next stage.

Properly installed pipeline is half the battle

We have already talked about how to prepare copper tubes for use, and now about installation itself. Firstly, always leave a margin of 1-2 mm, which will go into bends. By the way, you need to bend the tubes extremely carefully; the appearance of kinks (depressurization) and wrinkles (increased resistance to refrigerant) is unacceptable. In order to understand where to install an air conditioner in an apartment without violating the integrity of the fittings, use a special device - a fitting finder. After the tubes have been bent in the right places, it is necessary to put thermal insulation on them. Often, special hoses made of polyurethane foam are used. Then we put on the flanges and flare the tube. Next, you need to connect the pipelines to the fittings. It is important here not to confuse the inputs and outputs, for example, a cold indoor unit with a hot outdoor one, and vice versa. Modern models may have different diameters of fittings, so doing something wrong will not work.

At the final stage, tighten the nuts. Do not forget that you are dealing with copper, and this is a very soft material that cannot be subjected to much force, so do not pinch the flanges. Final tightening will be required during sealing. Up to this point, you should already decide where to install the air conditioner, since redoing everything is very costly and time-consuming. Move on to the drainage. To do this, you will need a plastic tube that is connected to the drain pipe.

Mobile air conditioner: how to install and where to do it

Everything here is somewhat simpler than in the case of other types of split systems. The fact is that mobile air conditioners practically do not require additional tools for installation. You only need a piece of a special pipe that will go outside. But it is not ordinary, but two-layer. Air for conditioning flows through one circuit, and exhaust air comes out through the second. If you don’t know which air conditioner to install in an apartment with a small area, then definitely choose a mobile one. It does not take up much space and can stand on the floor; special wheels allow you to move it.

Almost always the pipe goes out the window, and there is no need to drill or chisel anything. For example, you can display it through a window, which is especially important. You can even install it in the kitchen or bathroom if required. Do not forget that the tube must be free of defects. One end is connected to the outlet in the split system, the other goes outside. It is worth drawing your attention to the fact that no external units are needed, but you will have to sacrifice power. That’s probably all that can be said briefly about what a mobile air conditioner is, how to install it and where to do it.

A few words about which split system to choose

Currently, there is a large selection: column, ceiling, multi- and other air conditioners. However, for the average person, a wall-mounted unit will suffice. However, consider the power of the unit. It should be selected with a margin of 5-10%. For the bedroom, it is important to install split systems that operate almost silently, which will not disturb your sleep. What kind of air conditioner should I install in an apartment in a children's room? In most cases, it is advisable not to do this at all. And if this is simply necessary, then you should give preference to a low-power model with a fine air purification function.

As for the manufacturer, the leaders today are companies such as LG and Samsung. Despite the high prices, you will receive a quality product that will delight you for many years. Choose a device with remote control, it is very convenient and saves your time and effort. For apartments of 30-35 square meters, a split system with a power of 1.5-4.7 kW is quite sufficient. We figured out which air conditioner to install in the apartment. Now we can talk about completing the installation yourself.

Install an air conditioner yourself: vacuuming and sealing

To ensure proper sealing, do the following. Buy half a liter of distilled water and add a spoonful of soap shavings. Then mix everything thoroughly until you obtain a soap solution. All this can be done after you have decided where to install the air conditioner in the room. Next, you need to open the outlet nipple and connect a pump, maybe even a bicycle one. It is necessary to inflate until air stops escaping. To understand when this moment comes, you need to apply a little soap solution to the pipe. When finished, tighten the threaded connection 1/8 turn. You have probably noticed that installing an air conditioner with your own hands is not so difficult, especially since almost the entire path has been completed.

Vacuuming is performed as follows. A vacuum pump is placed on the nipple, which should pump for an hour. During this time, all moisture and dust will be removed from the system, which is what we actually need. The air that got there during installation will also be removed. That's all, you were able to install a split system without the help of specialists. All that remains is to fill it with refrigerant. It is necessary to fill it up to the green mark on the pressure gauge, however, before doing this, look at the instructions, everything is indicated there. Now you know how to install a window air conditioner, as well as a wall-mounted split system.

Conclusion

So we figured out where you can install the air conditioner. But don’t rush to choose a place, since redoing everything later will be long and difficult. After reading this article, you might understand how to install an air conditioner yourself. The main thing is to follow the sequence of actions and use a quality tool. The use of files and saws for metal when working with tubes is not allowed. Because this will lead to breakdown. By the way, it is worth noting that after completing the work you need to perform testing, that is, verification. This will let you know if everything was done correctly.

Testing is extremely simple. You can do everything via the remote control, there is a corresponding button. This option is also available directly on the split system body. The air conditioner should enter test mode, but if this does not happen, then something is wrong. Perhaps it's an electrical issue, a sealing issue, or a vacuum issue. There can be a lot of reasons. Another important point: if you install it yourself, you risk losing all warranties on the product, and this is very, very bad. For this simple reason, think twice before doing anything yourself. In some cases, it really makes sense to install, for example, an inexpensive split system yourself. If you purchase expensive and powerful equipment, then do not spare 6 thousand to call the experts. In this case, the installation will be carried out correctly, and if problems arise, you can call the organization that installed the split system and solve them.

An air conditioner is an electrical appliance that cools the room in summer and heats it when the temperature approaches zero. Installation of a split system or other climate control device has a number of features and nuances. Knowing them and observing technology and safety requirements, you can easily install the equipment yourself.

Principle of operation

An air conditioner is a technically complex device designed to maintain the indoor microclimate. Individual models may differ in the method of air supply, number of blocks, power, size and other parameters.

For example, based on the number of blocks used, there is the following classification:

Monoblocks. All functions are performed by one block. This design is easy to maintain and operate, and has a long service life. The main disadvantage is the high cost.
Split systems. The design consists of two independent blocks. The first is mounted on the outer wall of the house, the second - inside. The blocks are connected by a tube through which freon moves. The internal unit contains the evaporator and fan, other parts are located in the external one.
Multisplit systems. With one external structure, such structures have a different number of internal blocks. This is convenient if the owners plan to provide an optimal microclimate in several adjacent rooms.

This air conditioner consists of two blocks, communications and remote control

Regardless of the model, the functioning of any climate control device is based on the property of liquids to give off heat during condensation and absorb it during evaporation.

The main components of the unit include:

A compressor in which freon is compressed and then sent to the refrigeration circuit.
Evaporator. Here the refrigerant evaporates and enters the gaseous stage.
A capacitor responsible for the reverse process - the transition of freon to the liquid stage.
Thermostatic expansion valve (TEV), which reduces the pressure of the refrigerant before sending it to the evaporator.
Fans that blow air over all important parts.

All components, with the exception of fans, are connected by copper pipes. The result is a refrigeration circuit with a constantly circulating refrigerant mixed with compressor oil.

The operating principle of most air conditioners is as follows:

The evaporator sends freon gas to the compressor. At this moment, the refrigerant temperature reaches 10–20 degrees at a pressure of 3–5 atmospheres.
In the compressor, freon is compressed. The pressure increases to 15–20 atmospheres and the refrigerant is heated to 80–90 degrees. After this, it is redirected to the capacitor.
In the condenser, the refrigerant cools and becomes liquid. The air flowing through the assembly heats up.
Next, liquid freon, under increased pressure, is transferred to the expansion valve. In most household units, this device is a copper spiral pipe. During the circulation process, the pressure and temperature of the freon decrease, and some of it evaporates.
The freon then goes into the evaporator. Here it finally takes on a gaseous form, cooling the room where the air conditioner is installed. The air in the room becomes cooler. Next, the gaseous refrigerant under reduced pressure is supplied to the compressor and the cycle begins to repeat.

All air conditioners operate on this principle, regardless of the number of units and other features of a particular model.

Tools and equipment

Installation of split systems and multi-split systems is best carried out simultaneously with a major renovation of the premises. If the walls are already finished, you can safely order new cladding.

For installation you will need the following set of tools and materials:

Powerful hammer drill and set of chisels. When installing, you will need to drill a hole with a diameter of 10 centimeters in the load-bearing wall.
Pipe cutter. It is not allowed to cut refrigerant pipes with a regular hacksaw. Copper filings and crumbs that will inevitably remain after cutting will quickly damage the compressor.
Rebar detector. When installing a split system into a concrete wall and hitting the reinforcement during the work, you will have to make another hole.
Pipe flaring kit.
Bicycle pump, which is used to check the tightness of the system.
Vacuum pump. With its help, the system is checked for leaks.
Pressure gauge, phase indicator, tester.

It removes moisture and air from the system for subsequent leak testing

The specific set of materials depends on the type of air conditioner being installed and the installation features. In particular, to install a split system you will need the following:

Copper pipes with return nuts and thermal insulation material. Necessary for laying the route.
20A electric circuit breaker and cable.
Decorative boxes for laying pipes, drainage and electrical cables. If the routes are laid in grooves, the electrical wiring will be placed in a corrugated pipe.
Brackets for mounting external and indoor units.
Drainage hoses.
Fittings, bolts, fasteners, screws, dowels, etc.

It is better to purchase a copper tube with some reserve. With a long enough pipe, you can lower the outdoor unit a little lower. This allows you to compensate for the slight overspending on the purchase of a good thermosyphon.

When purchasing a pipe in a coil, you need to make sure that its ends are rolled using the factory method. Cracks and dents are excluded.

Preparatory work

Before proceeding with the installation of the air conditioner, it is necessary to carry out a number of preliminary procedures and calculations. First of all, you need to decide on the place where the installation will take place.

Choosing an installation location

The quality of air conditioning, the well-being of the owners living or working in the room, and the design of the house or apartment depend on where the air conditioner is installed.

The choice of location for a window air conditioner is obvious. The mobile air conditioner can be installed in any desired location. The main problem is with classic split systems.

When choosing a place for installation, in particular, an indoor unit, you can follow several recommendations:

Do not place the device on the wall opposite the entrance to the room.
The distance from the block to the ceiling should not be less than 10 centimeters.
The air flow is directed in the direction where people are least likely to be. If the split system is installed in the bedroom, it should be placed away from the bed. If remote installation is not possible, the unit can be installed above your head so that cold air flows to your feet.
The air conditioner is installed at some distance from the cabinets. If the furniture is placed next to and slightly below the split system, air currents, blowing dust from the top cover, will form a dusty curtain.
The air duct route can be laid in boxes or pre-equipped gates. The minimum length of the air duct can reduce the cost of installing a split.

The location for installing the external unit is selected separately. The simplest option is to place the block on the external wall of a balcony or loggia. Installation can also be done on the roof. The second method is relevant for residents of the top floors of high-rise buildings.

Air conditioner check

Before carrying out installation work, the air conditioner must be carefully inspected. The owner must ensure that the unit was not damaged during transportation and that all parts specified in the package are available.

When inspecting the air conditioner, you must ensure the following:

There should be no dents, cracks or other deformations on the external unit of the split system.
There should be no foreign elements at the connection points. The thread must be clean and undamaged. Deep scratches on the metal are unacceptable; this is a sign of defective or unskilled dismantling.
There are stickers on the external unit that detail the manufacturer, power and other information about the air conditioner. All this data must match the instructions.
The electrical circuit of the air conditioner should be located under the cover or in another accessible place.
The split system must include screws with which the remote unit is attached to the bracket. If their availability is not provided by the manufacturer, they are purchased separately.
Damage to the indoor unit is not allowed.
The filters should be free of stains, odors, and traces of detergents. If this is present, it means the air conditioner has been used and washed.

If no visible deformations are detected, you can check the operation of the air conditioner. To do this, the indoor unit of the split system is started in “fan” mode from the nearest outlet. There is no need to check other modes; this will lead to incorrect operation of the device. If everything works properly, you can disconnect the unit from the network and continue the installation.

Do-it-yourself air conditioner installation

There are several types of air conditioners offered on the climate control equipment market. The most common among them are conventional and multi-split systems, window, floor and duct models. The installation of each of them has its own characteristics. Let's look at the installation of all systems in more detail.

Split system

It is the most common type of air conditioner. This is a structure consisting of two blocks connected to each other. One of them is located indoors and provides an optimal climate, the other is installed outside.

Outdoor unit

Installing the external part is the most difficult part of installing a split system. When decorating high-rise buildings, such work is carried out using industrial mountaineering.

First, brackets are attached to the wall of the building. With some models of split systems they are included, for others you will have to purchase them additionally. To fasten the parts, anchor bolts are used, which are purchased complete with brackets. Thanks to the reliable fastening, the block will not fall, even if it gets icy.

When installing the block, it is necessary to maintain a distance from the walls. Specific numbers are indicated in the documentation for the split system. The structure is placed horizontally; during installation you need to use a building level.

Some blocks weigh more than 100 kg. A lift is required to install them.

The installation technology is as follows:

Holes for anchor bolts are drilled strictly perpendicular to the wall surface.
The minimum distance by which the block must be moved away from the wall is 20 centimeters. The exact numbers are indicated in the instructions.
All communications approaching the block are securely fixed.
There should not be any architectural structures or other air conditioners directly above the unit. A small visor is installed on top.
The mass of the block can exceed one hundred kilograms. When selecting a bracket, it is necessary to take into account that it must withstand double the weight of the unit: this will allow it to withstand the effects of various weather conditions.

The maximum distance to which open communications of a split system can go along the wall does not exceed 1 meter.

Installing an air conditioner on a ventilated facade and loggia has its own characteristics. The difficulty of the first case is that the building is already lined with a layer of insulation and porcelain tiles fixed on metal guides. Installation on a ventilated facade is carried out as follows:

Certain nuances are also associated with installing an air conditioner on a balcony or loggia. Installation of an outdoor unit inside a building is prohibited, which is why it is often placed on a parapet. Some homeowners install a split inside a glazed loggia. In this case, the windows must be left open, otherwise the system will not work properly.

Indoor unit

The block is installed under the ceiling, with a certain distance from the walls. The distance to the nearest surfaces for each model is determined individually and is indicated in the accompanying documentation. During installation, it is necessary to take into account that the indoor unit is installed higher than the external one.

The system is installed in two ways:

Parallel to the floor. The structure is set to the building level.
With a slight slope (about 5 degrees) towards the drainage. This facilitates the drainage of condensate.

Before starting installation work, the mounting points to the wall are marked. For this, chalk and a building level are used.

First, the mounting plate is attached. Most often it is included in the installation kit. If the package is incomplete, you need to measure the parameters of the block and purchase the part. 4–6 screws are used for fastening.

A block is installed on the plate. For easy access to the fittings for further work, you can place a small object, for example, a screwdriver, under the air conditioner.

If there are increased high-frequency vibrations in the room, for example, from machine tools, there is no need to install a split system here.

Laying routes and communications

A hole is required to carry out the necessary communications. It is drilled with a hammer drill, the diameter of the drill is up to 5 cm. If drainage is laid in the same route, the channel is made with a slight slope (up to 10 degrees) towards the street. A section of the route is laid into the wall; if this is not possible (for example, after indoor renovation), external installation can be carried out using a decorative box.

The standard communication route includes:

Freon line - copper tubes of a given length.
Wiring.
Drainage - occasionally.

Freon pipes, wiring and drainage hose are laid

The length of electrical wiring and pipelines depends on the length of the route, taking into account a small margin. Copper tubes are cut with a pipe cutter; when using a grinder or other devices, sawdust and burrs appear. Before installation, the pipes are placed in a heat-insulating shell - this prevents construction debris from penetrating inside.

When installed externally, communications can be hidden in the cable channel

After installation, it is necessary to connect the wiring and freon pipe line. The wiring diagram is contained in the instructions supplied with each air conditioner.

To connect the freon pipe, you need to adjust its size, remove burrs (if any), thread the nuts and flare the edges. After this, the pipes are brought to the fittings of both blocks, connected, and the nuts are tightened with a wrench. It is necessary to ensure that all connections are completely sealed.

Drainage

A reinforced plastic pipe is used for drainage. It is connected to the drain pipe, for which a threaded flange is used (if this method is provided for in the design) or a heat-shrinkable tube.

According to technology, drainage is discharged into the sewer. In practice, many owners take the tube outside the house. It is important that it does not bend upward: water accumulates at the bend, and fungi and microbes appear and spread in it.

Final works

After installing communications, laying a route, etc., the line is checked for leaks and vacuumed. The pump is connected to the port using a manifold and pumps out air for 20 minutes. Then the device turns off, after which it is necessary to observe the pressure for a while. If the readings on the pressure gauge have not changed within half an hour, the system is considered sealed.

After the final check, you can open the taps on the external unit and fill the system with freon. Refrigerant leakage is not allowed: this not only provokes malfunctions in the split system, but also negatively affects human health. Next, the structure is connected to the network. In most household air conditioners, power is supplied to the indoor unit, for which you only need to place an electrical outlet nearby.

How to install a window air conditioner yourself

Installing a window-type air conditioner does not require laying routes, carrying out work at heights and other difficulties inherent in installing split systems.

Free gaps are closed with decorative inserts

When working, you must follow the given sequence of actions:

Preparing the site. The glass is removed and a “jumper” is installed.
Bracket installation.
Installation of the block.
Connecting a drainage hose, if provided for by the design.
Connecting the air conditioner to the power supply.

Floor system

The floor-standing air conditioner also does not require installation of an external unit and can be installed anywhere. It is only necessary to ensure that the heated air is discharged outside the room. Some simply duct the air duct out of an open window - this minimizes the operation of the air conditioner itself.

To prevent heated air from the street or from the air duct from entering the room, you need to equip a ventilation duct. To do this, you can order a plastic window with a suitable hole from a specialized organization, or purchase plexiglass and cut it yourself.

An open window makes it pointless to cool the room

To make a hole of suitable size in the plexiglass, you need to attach an air duct to it, circle it in a circle and cut a hole. An improved soldering iron is suitable as a cutting tool: a cut is made in the “tip” of the tool into which a blade from a breadboard knife is inserted. When the device operates, the blade heats up and begins to cut plastic.

Duct

The main advantage of duct-type air conditioners is the ability to combine cooled air with street air, thereby performing ventilation functions. For this purpose, an additional air duct is connected to the unit. To organize the mixture, the following procedures are necessary:

A hole for the air duct is drilled in the outer wall.
From the street side, a grate is inserted into the hole. An electric valve is installed next to it. When the air conditioner stops, it blocks the air supply.
The air duct is installed. Air will flow through it into the filter.
Next along the chain, an electric heater is installed. Filtered air enters it. Heating ensures optimal room temperature in winter.
The final unit is a duct fan that provides air circulation.

Installation of the duct air conditioner itself consists of installing an external and internal unit, as well as a pipe system. The external unit is similar to the same as that of a conventional split system. The indoor unit is installed under suspended or suspended ceilings.

If installation takes place in a private house, it can be installed in a technical or attic room.

The peculiarity of this type of air conditioner is that it can be used to control the microclimate in several rooms without damaging the interior decoration. This is ensured by a system of ventilation ducts, from which heated or cooled (depending on the settings) air passes from the unit through drilled and grated diffuser holes into the rooms.

The air is distributed through pipes and enters the room through diffusers

Some models allow vertical installation. In this case, the unit is located in the gap between the walls. This must be provided for at the construction stage of the building. Some models can be mounted on a load-bearing wall and hidden with a false beam or partition.

The winter kit allows you to use the split system at very low temperatures. The package includes:

A device that heats the compressor crankcase of an outdoor unit. Thanks to it, a “cold start” becomes impossible.
A device that regulates the speed of fan rotation. It redirects air flow and prevents freezing inside the air conditioner.
A device for heating the drainage, installed in the indoor unit. Thanks to this detail, icing of the condensate outlet is eliminated.

Modern devices are equipped with their own temperature sensors and automation

Installation proceeds as follows:

The protective covers and top covering of the external unit are removed. The front panel is removed. The need to dismantle the rear wall depends on the design features of the particular model.
The connection diagram for the fan controller depends on the type of device being connected. For example, Fasec-33 is installed in the neutral gap (wires that go to the capacitor), the Ballu device is built into the phase gap.
The crankcase heater is built into the bottom of the compressor and connected to the power supply. Modern models have their own temperature sensor, and when the set temperature is reached, the heating turns off automatically.
Band type heaters used for the drain system are installed directly inside the hose and are powered from the crankcase heater or compressor start terminals. The drains only need to be heated while the air conditioning compressor is running and condensation may form. The length of the heater should completely cover both the street part of the drain hose and the 15–20 cm located in the wall.

Before installing parts, the unit is disassembled

Safety precautions when installing an air conditioner

When installing the air conditioner, the following safety precautions must be observed:

The unit should not be installed in close proximity to potential sources of moisture or heat.
The unit should not be installed next to a doorway.
Let us repeat that air currents should not be directed towards a person.
It is necessary to ensure that the condensate drains, otherwise bacteria may appear.
The block is installed on a strong wall. During installation, a special plate and brackets included in the kit are used. Installation is carried out by level.

Many works related to the installation of a household air conditioner do not require qualifications and can be done independently. If you have the skills of a builder or electrician, installation can be carried out without serious difficulties.

In the hot summer, people begin to realize what they are missing in their home improvement.
Air conditioning allows:

get rid of problems such as heat and stuffiness;
maintain the desired temperature level in the room, as comfortable as possible for humans and household appliances.

Unlike fans, causing drafts and leading to colds, modern air conditioners maintain the set temperature in automatic mode without problematic air flow movements.

Household appliances according to their design are divided into two main classes:

monoblock;
multiblock devices.

Monoblock installations consist of one working unit and are divided into the following main types:

Window. Such devices must be installed in the window opening. Modern systems are produced with a power of 1.5-6 kW, may have an additional air heating system, automatic temperature control and remote control. The price of such an air conditioner is from 12,000 rubles and higher depending on the configuration.

Monoblock air conditioner mobile type designed for floor installation and can move around the apartment. He does not require special installation; The only condition is that the air exhaust hose must be brought outside. The hose has a diameter of up to 15 cm and a length of up to 2 m, which limits movement by distance to the window.

Rooftop devices, which are rarely used as domestic installations.

Multi-block designs are represented by split systems of various installations with two or more blocks. They have an external unit containing a compressor and are installed outside the room, and one or more internal ones for distributing air flows.

The most common type of split system is the wall-mounted version of the indoor unit. It is connected electrically and hydraulically to the outdoor unit and is mounted on the wall anywhere in the room. Such devices are produced with a power of 2-7 kW and are capable of cooling a room with an area of 12 to 75 square meters. m. The distance between elements (pipeline length) is selected up to 7 m.

Unlike a simple split, which provides 1 indoor unit, a multi-split system is based on the installation of 2 to 5 indoor units, which can have different designs and power (within 2-5 kW). Such a system allows you to distribute air conditioning throughout the apartment, without cluttering the outer surface of the wall with additional blocks.

Air conditioner power calculation

Selecting an air conditioner by power. This important parameter of the device depends on the volume of the room.

S– area of the room;
H- ceiling height;
q– heat transfer coefficient of the walls (for the sunny side q=40, for the shady side - q=30) with the addition of 10% for the heat generated by people and household appliances (except for the kitchen).

For example, for a room of 30 square meters with a height of 2.5 m, facing the sunny side of the house, the power should be 30 x 2.5 x 40 x 1.1 = 3300 W. Standard range of split system capacities: 2; 2.6; 3.5; 5.3 and 7 kW. Hence, you will have to choose an air conditioner with a power of 3.5 kW.

How to choose the right air conditioner

With the onset of the summer season, many people are wondering: which air conditioner to choose? When selecting, in addition to power, We recommend paying attention to the following characteristics:

electricity consumption, freon line length;
weight;
drainage features, design;
important - the presence of automatic temperature control, remote control, the presence of fittings for fastening;
and, of course, the price of the device.

Watch our video on how to choose the right air conditioner:

Operating principle of the air conditioner

All household split systems have a similar operating principle:

Air cooling occurs due to the fact that refrigerant(freon) at the moment of transformation into gas in the evaporator chamber takes up a lot of heat.
Using a vacuum pump, gaseous freon is pumped out of the chamber and enters the condensation chamber, where again turns into liquid.
Then a new cycle begins, and this repeats constantly. It should also be taken into account that in the evaporation chamber When freon evaporates, water condensate is formed, accumulating at the bottom of the chamber and requiring drainage.

A special feature of the split system is remote separation of the location of the condensing chamber, compressor and vacuum pump, and evaporation chamber.
Due to the fact that all elements that produce noise (compressor, pump) are placed in the outdoor unit and removed from the room, it is ensured silent operation.
Freon is distilled through annealed copper tubes through the indoor unit, where the evaporation chamber is located and the air is cooled.

System energy consumption can be reduced by the following measures:

minimum length of the freon line;
good drainage of the evaporation chamber;
preventing the outdoor unit from heating up under direct sunlight.

Energy consumption is reduced when the outdoor unit is located below the indoor element, since, when heated, any liquid itself rushes upward, which means that it does not have to be advanced artificially.

The tightness of the entire system is important - any microscopic defects can lead to volatilization of freon.

Do-it-yourself air conditioner and split system installation

Installation of a split air conditioner includes the following main steps:

Preparatory work.
Installation of outdoor and indoor units.
Freon pipeline layout.
Installation of a drainage system.
Electrical circuit installation.
Filling the refrigerant and sealing the system.

How much does it cost the family budget to use an electric boiler to heat a private home? .

When installing the device yourself, you will need the following installation materials and equipment:

for freon route: copper tube (two sizes); return nuts for tubes (two sizes); material for thermal insulation of the route;
for electrical installation: cable, circuit breaker of at least 25A, connecting (terminal) block, RCD, PVC electrical tape, corrugated pipe for cable;
for drainage system: hose for outdoor and indoor units, fittings for connection to the sewer system and connection;
for fastening: brackets for the outdoor unit, mounting plate for the indoor unit, anchor bolts, dowels and screws, rope (cable) to hold the outdoor unit during installation;
for filling and sealing: freon bottle, silicone sealant;
auxiliary elements: plastic boxes for pipes and drainage (60-100 mm) and cables (20-30 mm), clamps, pipeline fasteners, screws, dowels.

Preparatory work

The preparatory stage includes a number of Activities without which you cannot start work:

preparation of the installation kit;
studying the instructions;
checking the availability of all parts;
determining the location of the blocks;
route markings; clarification of the possibility of the electrical network.

Installation work must begin by reading the instructions by use. Without instructions, where the specified device parameters are given, high-quality installation is impossible. If the instructions are lost, then you should find a similar air conditioner model (company office, service centers, Internet).

The instructions specify the following parameters:

operating current;
permissible length and diameter of the pipeline;
drainage requirements specific installation requirements;
type of refrigerant and its operating pressure;
mass of blocks.

Placing Blocks

When determining the place where you need to install an air conditioner in an apartment, you must follow certain rules.

The internal one is installed close to the ceiling, but not closer than 15 cm.
There should be a free gap of at least 10 cm around the block.
When installing, the unit should be hung at an angle of up to 5 degrees.
The location of the element should allow free supply of pipes and cables, and should also be located away from heat sources.
The distance to the block from the window should not exceed the maximum dimensions established for the length of the freon route.
The outdoor unit is installed on the outside of the wall below the inside, but no more than 3 m.
Its location must be chosen so that installation can be easily carried out from the window opening.
The length of the pipes from the unit to the entry into the room should not exceed 1 m.
During installation, the outer element is moved 10 cm away from the wall. It is prohibited to install the unit near a gas pipeline.

Planned Places for installing blocks are marked with chalk or marker with markings for mounting brackets. Then, between them the pipe laying route is marked for freon and power cable. Noted electrical distribution box mounting location. Drainage systems are being marked s and taking it to the sewer.

Routing and laying of freon route

Installation of the system consists of fastening the blocks, laying and fixing the pipeline, electrical wiring and drainage system.

Pipelines and cables along the wall can be laid in three ways:

fine;
plastic box;
corrugated hose.

Fines allow you to make a hidden route, but require a lot of time and effort. To lay all highways, a standard standard is punched into the concrete. channel size 40 x 60 mm.

Chasing is carried out using a grinder, hammer drill or wall chaser. The simplest and highest quality way is to use a wall chaser, which allows you to make a channel in one pass, but the cost of such a power tool is high. More A common method is to cut 2 longitudinal slots with a grinder followed by sampling of concrete between the slots with a hammer drill.

A simpler installation method is a plastic hose or box. They are attached to the wall using dowels, for which holes with a diameter of about 8 mm are pre-drilled in marked places. To carry out the route through the wall, it breaks through hole with a diameter of 5-8 cm using a hammer drill.

Installation of drainage system

Correct installation - drainage of the air conditioner into the sewer, but this is only realized when sewer pipes are located close to each other. Most often, the drainage hoses are simply vented outside (the volume of condensate is small and is released in the form of droplets). A feature of drainage installation is the need to ensure gravity flow of water, i.e. the hose should drop 3 cm for every 1 m of gasket length.

Electrical connection

The cable for powering the units is placed in a corrugated hose or pipe pierced in the wall. It extends through the wall into the same hole as the tubes. Along the outer wall and in the wall hole The wiring is placed in a corrugation. The channel for installation inside the wall has dimensions of at least 10 x 10 mm.

The electrical circuit of the air conditioner is disconnected from the main electrical network in the nearest junction box, if the cross-section of the supply wires allows. More often, necessary to an existing channel extend additional cable(wire) of the required cross-section. A terminal block is installed in the junction box, in which the connection is made.

In the introductory an RCD is installed on the electrical panel with a circuit breaker for a current of at least 25 A.

The figure shows the electrical connection diagram for the air conditioner:

Installation of split system

The outdoor unit is mounted on brackets, the dimensions of which must take into account the weight of the device, as well as weather factors (snow, icing, wind). The brackets are fastened with anchor bolts, and holes in the wall for them are punched with a hammer drill. Usually, brackets are included in the kit. It is recommended to install a canopy over the outdoor unit.

To install the indoor unit previously on fixed to the wall using dowels mounting plate included with the air conditioner. Holes for dowels are drilled with an electric drill or punched with a hammer drill. According to the installation technology, the block itself is installed with an angle of 3 to 5 degrees. to direct the flow of cooled air downwards.

When laying copper pipes, special attention should be paid to their bending. To avoid deformations, bending should be carried out using a special device - a pipe bender. The permissible bending diameter is 20 cm. The tube must be cut with a pipe cutter, and the cut end must be processed with a scraper.

A heat-insulating polyurene foam hose is placed on the tubes(flex). Threaded flanges (return nuts) are installed at the ends of the tubes, and the end is rolled using a reamer. The flanges are installed on the fittings of the blocks and tightened, but so as not to deform the soft copper base of the tube.

Special attention - the thread of the flanges must be directed towards the end, and when fastening the cold outlet of one unit must not be allowed to be connected to the hot outlet of another.

Refrigerant charging and installation completion

The final stage of air conditioner installation includes filling the system with refrigerant, sealing and testing.

After installation is completed, the electrical network is connected and the system is charged with freon.

air is pumped out using a vacuum pump;
then the system is filled with freon from a cylinder, where it is under pressure.

The tightness of the structure is controlled by a pressure manifold.

If the collector does not show an increase in pressure within 60 minutes, then the tightness is considered normal; otherwise, the sealing of the joints should be checked. The easiest way to check is soap suds. Sealing of broken joints is done by applying silicone sealant.

Testing is carried out when turned on in different modes. Switching on is done using an automatic switch, and the test mode is set on the air conditioner.

Rules for using air conditioners

When using air conditioner in everyday life You should adhere to some rules:

Do not direct a strong stream directly at a person so as not to cause a cold;
It is not recommended to allow a temperature difference between adjacent rooms of more than 10 degrees;
The recommended optimal temperature is 20-22 degrees;
You should periodically turn off the device and ventilate the room to restore the ozone content;
recommended to use ;
It is necessary to carry out preventive measures - replacing filters, adding freon, cleaning the system.

It is prohibited to turn on a faulty air conditioner: sparking at electrical contact points, clicking inside, cable heating, refrigerant leakage.

Air conditioner installation cost

Installing an air conditioner yourself requires certain costs - purchasing fasteners, refrigerant, auxiliary materials. In general, everything costs should not exceed 1000 rubles.

Air conditioner installation by a specialist can be produced without spending your own time and effort, but will require the lowest prices from 6000 rubles. By time installation of a split system will take no more than 8 hours if you have the necessary tools and materials.

Compared to other air conditioning devices, the split system has a more complex two-block design. This system consists of an external compressor-condenser module and an internal evaporator module with a corresponding number of communications through which freon and electricity are supplied and condensate is discharged. This scheme complicates installation, but does not exclude self-installation. To install such an air conditioner yourself, just read the instructions, make up for the lack of knowledge and experience through Internet resources, and consult with specialists.

Installation features depend on the design of the indoor module, which can be wall-mounted or floor-mounted. To save space, small apartments usually use a wall-mounted air conditioner. This split is somewhat more difficult to install due to the need for durable wall mounting. But regardless of the details, the work is carried out in the following sequence:

installation of separate wiring;
installation of an external condenser unit;
fastening the evaporator (indoor unit);
connection of communications with vacuum;
test activation.

Tools

To install the split yourself you will need a tool. It is recommended to include in the set:

a drill with a hammer drill and a corresponding set of drills that is capable of breaking through a solid concrete wall;
pipe cutter for neatly cutting pipes without the threat of clogging with copper shavings;
a kit for flaring the edges of tubes, which will ensure the tightness of the connections;
an example that can be used to strip the ends of connections;
a pump, possibly a bicycle pump, to assess the tightness;
vacuum cleaner, to remove moisture from the system by vacuuming;
indicator screwdriver and tester for wiring;
pressure gauge for pressure control.

How to choose a place

Before installing split system modules, it is necessary to correctly determine their location. For the external unit, the space should be:

protect the device from direct sunlight and exposure to dust;
guarantee the stability of the structure;
provide sufficient free space for normal operation of the device.

Here such a situation is excluded, and the necessary protection of the unit is provided by the visor. An additional advantage is ease of maintenance. When choosing a location for the compressor you need to:

provide protection from sun or heating;
eliminate the threat of ignition of various vapors and gas leaks;
provide the required free space and distance from the floor around the perimeter of the block as required by the instructions;
prevent interference from constantly operating electrical appliances (distance of at least a meter);
guarantee the strength of the wall, preventing the structure from collapsing.

Installation of separate wiring

A split system, even in its most low-power version, requires at least 1.5 kW. Such power requires a separate line, unloaded by other consumers, especially in houses earlier than 1990.

It requires:

two-core wire with a cross-section of 1.5 to 2 mm, always copper;
16A circuit breaker.

If you plan to hide the wiring in a groove, then you should take care of this during the renovation so as not to spoil the expensive interior of the renovated apartment. When the idea to install a split came after a renovation, the solution may be to install additional wiring in the box. In any case, this will allow:

avoid overloads;
prevent device failure;
eliminate the possibility of fire as a result of a short circuit.

Installation of an external condenser unit

The complexity of this stage depends on the location where you decide to place the air conditioner. Three options can be used:

on the open balcony;
on the loggia;
on the wall.

On the balcony, it is enough to install short brackets and place the module on them. The protection function will be performed by a standard balcony canopy.

When choosing a loggia, you can limit yourself to the same brackets, but you should remember that a closed space does not provide the necessary air circulation, which will damage the air conditioner.

Open doors will help avoid this, which reduces the value of the loggia, especially in winter. It is impossible to mount the module on the wall without reinforced brackets, which must confidently support a weight several times greater than the mass of the unit itself. To attach them, it is better to use long anchors with a diameter of 20 mm.

Mounting the evaporator and installing communications

Before installing it, you need to mark the mounting locations. Check them horizontally and vertically using a level. After this, the work is performed in the following order:

Holes are drilled according to the markings and anchors are inserted.
The mounting plate is secured with screws;
In accordance with the position of the block, a hole is punched for communications (50 - 80 mm) with a slight slope outward for drainage.
A waterproofing cup with a tube is mounted in the holes.
a check is made to ensure that the wire is connected correctly to the terminals in accordance with the diagram.
Tubes with thermal insulation made of flex and drainage are connected to the corresponding pipes.
If it is necessary to lengthen the edges of the tubes with the nuts on, they are first flared.
Using electrical tape, a compact bundle (route) is formed from tubes, drainage and wires, which is passed through the hole to the outside.
The indoor unit is hung on a mounting plate.

Having completed the above work, you can install the external unit on the previously fixed brackets and lead the route to it. Excessive force should be avoided when bending the tubes to avoid deformation and wrinkles (the permissible bending radius is at least 100 mm). If the air conditioner hangs over the sidewalk, then you need to take care of alternative options for discharging condensate indoors.

Sealing and vacuuming

It is impossible to install a split correctly without sealing and vacuuming the communications. Sealing the connections is done using a soap solution and a regular bicycle pump. The solution is applied to the connections and the tubes are pumped using a pump. When bubbles appear, carefully tighten the nuts by 1/8. The procedure is performed until the bubbling stops.

Then vacuuming is performed, which removes air, dust and remaining moisture. For this:

open several running ports;
connect the vacuum pump through the service port;
turn it on and wait for a pressure of 10 mmHg;
close the low pressure lever;
turn off the pump, return plugs to all open ports.

Testing

Before checking, fill the split with freon or refrigerant, depending on the requirements of the instructions, to the specified pressure. Testing is activated using a circuit breaker. If installation is performed correctly, the air conditioner will automatically enter test mode. Its result should be:

normal flow of cold air;
correct position of the blinds;
condensate drainage through drainage.

If all the signs are present, the split can be used every day. Otherwise, you will need to contact specialists. In this case, the warranty for the air conditioner will be lost.

So it is still not recommended to install such an air conditioner yourself. It’s better to immediately weigh your strengths and think about inviting a specialist.

Buying an air conditioner to create and maintain comfortable conditions in a room can become completely useless. It's no secret that when choosing an air conditioning system, we tend to listen to the opinions and advice of qualified specialists. We do not buy such a complex device at random, without taking into account the volume of the room, the material of the walls, the number of window and door openings. We get acquainted with the available information about the models of the selected brand. And many refuse the help of qualified installers, believing that installing an air conditioner in an apartment on their own is not a difficult job at all.

Nevertheless, the real prospect of damaging expensive equipment with poor-quality installation is obvious. In our article we will tell you how to install air conditioners in an apartment.

Types of air conditioners

The first device that maintains comfortable conditions in an apartment - temperature, humidity, cleanliness and speed of air movement - appeared in the first half of the 20th century, but in Russia air conditioners for residential buildings began to be used relatively recently.

Air conditioners can be divided into several independent groups:

mobile;
window;
split systems;
multi-split systems.

For a long time, the most popular in our country were window systems that are installed in a window or wall. This significantly reduces the level of illumination in the room. It consists of a single unit, so the installation of such a device is greatly simplified. Such models operate quietly, are quite durable, do not have freon leaks, and are characterized by maximum efficiency, but their price is high.

The air is removed through a pipe leading into the window. Condensation collects in a tray. The advantage of such systems is their mobility - you can place it anywhere, but the disadvantages, undoubtedly, include loud noise.

There is another subtype of mobile air conditioners. It is ductless, produces much less noise and uses little energy. The moisture that evaporates during operation enters the room in the form of steam, thereby increasing the humidity.

Split systems are a more modern device that consists of two parts - an indoor and outdoor unit. They are divided by type:

columned;
cassette;
channel;
ceiling;
central;
wall-mounted

Installing an air conditioner in an apartment involves installing the unit outside the room - on the facade, roof, balcony. It is connected by electrical wires and a drainage tube.

Selecting an air conditioner

When choosing a specific device, its power is calculated. In this calculation, it is necessary to take into account the area of the rooms, the degree of natural light, and the presence of heating devices. More powerful devices are suitable for the kitchen, and less noisy ones for the bedroom. And installing an air conditioner in an apartment, in particular in a children's room, will require choosing the highest quality mechanism. Speaking from an aesthetic point of view, it is better for the device to be hidden. A split system is most suitable for this.

Duct air conditioners

This device is a semi-industrial type device. It perfectly solves the problems of ventilation, air conditioning and temperature control in a fairly large room.

In this system, air passes through ventilation ducts. They have an unusual air supply and distribution system. For this purpose, a network of air ducts has been created.

Air from the street enters the external unit, then it moves through copper pipes, in which it is cooled and sets the desired temperature in the room. The indoor unit of the air conditioner is equipped with filters to purify the air.

Additional functions

Devices of this type are usually equipped with instructions, a control panel, and a set of additional filters. In addition, the duct air conditioner has an antibacterial air treatment function.

Advantages

Installing a ducted air conditioner in an apartment is justified if it is quite spacious (more than 120 square meters). Such systems are more suitable for estates and large private houses.

The duct air conditioner is very compact, it is almost invisible in the room, since its internal unit is mounted in closets, utility rooms, and under suspended ceilings. This allows you not to disturb the interior.

Air enters the room from the street. The developed air duct system allows the device to supply it to several rooms at the same time.

Flaws

Duct air conditioners have their weaknesses:

high noise level;
complexity of installation.

Installation of an air conditioner in an apartment (ducted) can only be performed by experienced specialists. They must accurately calculate the rules of air conditioning and ventilation.

Installing an air conditioner in an apartment with your own hands

Once the model has been selected and the appropriate device has been purchased, visually inspect the equipment. This is necessary in order to avoid any unpleasant surprises during its installation. All parts must be securely fixed, the air conditioner must not have mechanical damage.

After this, you should clearly determine the location of the external and internal modules of the device. In this case, you should follow certain rules for installing an air conditioner in an apartment - first of all, this is the need to take into account the aesthetic appearance of the device and ensure all its quality characteristics. To do this, consider the following:

Indoor unit - choosing a location

The equipment should be installed so that it is convenient to install it. The device must be protected from direct sunlight.
It is necessary to choose a solid wall so that the air conditioner is in the desired position when operating.
In order for air circulation to be of high quality, the installation location of the unit must be well ventilated - the distance of the module from the ceiling must be at least fifteen centimeters.
Get rid of various obstacles in the way of the cooled flow - screens, partitions, etc.

Preparatory work

If you decide to install this device yourself, then you will definitely need a diagram for installing an air conditioner in the apartment. It is usually included with all models. If it does not suit you, then look through the special literature to choose the best option for your premises.

The most labor-intensive part of the preparatory work is drilling a hole in the load-bearing wall and preparing grooves - recesses in the wall, which must be of such a size that utility lines can be placed in them.

If the gating process is unfamiliar to you, you can place these elements in a special mounting box. For drilling, it is better to use professional equipment - a powerful hammer drill equipped with a breaking drill with a carbide tip.

In order for the holes to be made with high quality, in accordance with technical requirements, some recommendations should be followed:

the hole diameter should be 45 mm;
It is necessary to drill at a slight angle (for timely removal of drained condensate).

At the preparatory stage, the outer bracket and mounting plate are installed.

When attaching external brackets, follow these simple rules:

the bracket is selected taking into account the dimensions of the external unit;
fastening is done with powerful screws and dowels, the diameter of which must be at least 12 mm.

Anchor bolts can be used.

Mounting the outdoor unit

Installation of air conditioners in an apartment must be carried out in compliance with all technical standards.

To ensure that the outdoor unit is securely installed, it must be carefully secured to all available mounting holes. To reduce vibration, we recommend using rubber pads.

Engineering Communication

Installing an air conditioner in an apartment will require certain technical knowledge.

After installing the external unit, you can begin installation. You will need to measure the length of the route connecting both units and cut the pipeline to the required size.

Then it is necessary to flare the connecting tubes. Now you need to connect the pipes of the indoor unit to the pipelines.

The final stage of work is fastening the indoor unit, connecting its pipes to the outdoor unit and connecting the electrical cable.

At this stage it is better to work together. One person lifts the line of the indoor unit, the second pushes the counter part of the line onto the street through the prepared hole. The indoor unit is then attached to the mounting plate.

At this point, the installation of an air conditioner in the apartment (you see the photo in our article) is considered complete. In conclusion, I would like to say: if you are not sure that you can do this, entrust it to professionals.

Air conditioning on the balcony

As a rule, installation on the upper floors of apartment buildings requires the participation of qualified installers who are certified to work at heights. Their services are not cheap. Therefore, the thought often arises of installing it on the balcony.

This solution has its own nuances. When installing the outdoor unit inside, it will overheat. In this case, it should be installed outside.

The operation of this device is accompanied by noise and vibration. You can get rid of this inconvenience by using mounts with shock absorbers. As you can see, installing an air conditioner in an apartment causes certain difficulties on the upper floors of high-rise buildings. Permission to install a block on the facade of a building, including on a balcony, must be obtained from the architecture department of the city administration.
