How to install an air conditioner in a private house

Each of us has his own idea of a comfortable life. Someone dreams of a large apartment in the city center, and someone needs a house to listen to forest birds singing in the morning. But to enjoy the country life to the fullest, you also need to take care of the engineering systems of your home.

The overall feeling of comfort, as well as your physical well-being, will depend on the level of equipment of the cottage. The easiest way to improve the quality of life in a country house is to install a split system. Air conditioning in a private house is not a luxury, but a necessity. A high-quality expensive split system can replace several devices, including an air humidifier.

In this article, we will tell you in detail how to install an air conditioner yourself in a private house, where to install it and what nuances to consider. However, we strongly recommend that you do not install the air conditioning system yourself.

Installation of an air conditioner is a complex multi-stage process. Therefore, if you have the opportunity, entrust this task to professionals. Installation works are not cheap, but they save your time and effort, and often also your money. After all, with inept installation, you still have to call an experienced master.

Stages of installation of the air conditioner. Briefly

How can I move the air conditioner to another place?

The installation of an air conditioner consists of several key stages, each of which can be divided into sub-stages. To better understand the amount of work to be done, read the brief description of the installation process:

Installation of the outdoor unit:

  • Selection of the place, installation of the bracket, transportation of the unit to the required height, installation of the unit, installation of the visor (if necessary);

Laying the route:

  • Selection and marking of the route location, selection of pipes and thermal insulation material, calculation of the length of pipes and thermal insulation, wall shtroblenie, laying of the route, connection to the outdoor unit, drainage pipe output, plastering of the route (with concealed installation);

Installation of the indoor unit:

  • Selection of the place, installation of the mounting plate, installation of the unit, connection to the track and electrical wiring, closing the track with a decorative box (for outdoor installation);


  • Vacuuming the system, filling the air conditioner with freon, testing various operating modes.

As you can see, the amount of work is rather big. Before installation, make sure that your skills, knowledge and strength are sufficient to complete the work in full. Installing an air conditioner will require you not only to have a large number of tools, but also help from friends and remarkable physical strength.

We recommend that you still entrust this work to professional installers. Yes, their services are not cheap, many owners of split systems are not ready for such expenses. But, believe me, this is not the item of expenditure on which you need to save. Incorrect installation leads to additional problems, which later still have to be solved for money. And sometimes this leads to more expenses than if you initially entrusted the installation to an experienced specialist.

And now let’s move on to a more detailed description of each stage of installation. We will tell you about the most important nuances that you should pay attention to.

Choose a location

The first question that you should ask yourself is where to install an air conditioning system? There are many opinions on this issue. We will share our experience.

Let’s start with the indoor unit. We recommend placing it in the living room where you spend the most time. For example, in the living room. If it is possible and you want to install air conditioning in several rooms, buy a multi-split system (it is also called a multi-zone system).

If the house is small in size (up to 60 sq. m.) and there is no vestibule, you can hang an indoor unit over the entrance door in the hallway. So the air flows will be evenly distributed throughout all the rooms.

When choosing a place, take into account the location of the curtains and the ceiling skirting board. Also remember that the device should not be located above the heating devices and in the immediate vicinity of the place where you are resting. The air flows should be directed above the head.

For outdoor unit

Now about the outdoor unit. If your house is built using frame technology, you need to take care of mortgages in the frame in advance. Otherwise, the facade will simply not withstand the weight of the outdoor unit. There can also be problems with aerated concrete: the material is very warm and practical, but porous and fragile. Often, outdoor blocks are torn off from the facade of an aerated concrete house. To avoid this, use reinforced fasteners or mount the unit on the roof/blind area/balcony.

When installing on a ventilated facade, you need to remove some of the plates and remove small parts of the insulation in the places where the bracket will be attached. Powerful anchors are used for installation. After the plates are put in place, if necessary, holes are cut in them for the bracket. And only then the outdoor unit is hung up.

But the owners of brick houses will not have any problems with the installation of an outdoor unit. The brick perfectly withstands weight if you use high-quality brackets. For ease of installation, it is better to drill holes for fasteners through the seam, since it is more difficult and longer to drill a stone.

We recommend mounting the outdoor unit on the north or west side. The installation on the east side is a compromise. On the south — a blatant mistake. The air conditioner must be protected from direct sunlight and heat.

Also, a visor can be mounted above the unit to protect it from atmospheric precipitation. This is an optional element, you install it only at your own request. Please note that in severe frosts, dangerous icicles can form on the visor, which will have to be periodically knocked down.

For communications

air conditioner route

As for the installation of the route, there are only two options: hidden and outdoor installation.

  • Hidden installation of the route* is the most preferred option. In this case, all communications are placed in a pre-prepared recess in the wall (in the so-called «strob»), after which they are plastered and finished.

  • Outdoor installation of the route * involves the installation of communications on top of finishing (wallpaper or painted walls) and their last hiding in a decorative box. This is not the most aesthetic option, but if the repair is already finished, then there is no other choice.

The location of the route is determined taking into account the location of the indoor unit. A clear marking is necessarily made on the wall, where the block and communications will be located, as well as what is the width of the future gate.

Install the outdoor unit

Installation of air conditioners in a private house often begins with the installation of an outdoor unit. The unit can be hung vertically or horizontally. Vertical installation is the most popular. But in the case of a frame or aerated concrete house, it is better to choose a horizontal installation.

Vertical installation is carried out on the facade of the house. You need to hang a bracket on the wall and fix it properly. Then a block is placed on the bracket. At the connection points of the unit with the bracket, use high-quality expensive gaskets designed to dampen excessive vibration. If they are not used, over time, the fasteners will loosen, the unit will begin to hum and make loud extraneous sounds.

For horizontal mounting, a special horizontal bracket is used. It is attached to a horizontal surface (flat roof or blind area). Between the bracket and the block, you also need to put vibration dampers. Horizontal installation of air conditioners in private homes is easier and safer, since you do not have to do the work standing on a ladder.

If you plan to perform vertical installation at a height of more than 3 meters, it is better to entrust this task to professionals. Believe me, your life and health are more important than any savings. Working at height is fraught with risk. And in a critical situation, you may not be able to cope with such a difficult job.

The distance between the block and the wall is 10-15 cm. When installing, use the building level, there should be no distortions. Pay special attention to the quality of the fasteners and the bracket. Do not buy the cheapest components. Give preference to materials from well-known manufacturers who can provide quality certificates and a guarantee for their products.

Lay the route

what is a stroba

The route consists of copper tubes and wires that connect the outdoor and indoor unit. Freon circulates through the tubes. Also, a drainage pipe is removed from the indoor unit to the street or into the sewer, condensate will flow down it.

The track is laid in a hidden way in the wall (then plastered and closed with finishing materials), or in a decorative plastic box (on top of the finishing finish). The first option is more beautiful and preferable, but if the repair is already completed, only the second method of laying the route remains.

Self-dismantling of the split system

The installation of air conditioning in the house continues. If you used a hidden installation method, the indoor unit must be hung after finishing (wallpapering or wall painting). It is much more convenient to carry out repair work this way.

To install the indoor unit, it is necessary to fix the so-called mounting plate on the wall and then hang the unit on it. The block is attached to the plate either with special latches around the perimeter of the case, or with another type of fastener. It is better to do the work with a partner. It can feed tools and parts while you are mounting the air conditioner while standing on a stepladder.

During installation, the track is connected to the unit. The copper tubes are connected to the fittings, and the electrical wiring is connected to the «brains» of the air conditioner. This stage requires special knowledge and skills from the installer. If you do not have them, it is better to use the help of a more experienced friend or a professional specialist.

Refuel and test the system


When the units are installed and connected, it is necessary to fill the track with a refrigerating agent (freon) and test the air conditioner. Before refueling, vacuumization is mandatory.

After vacuuming and refueling the system, it is necessary to carefully check the operability of the air conditioning system. This stage usually takes at least an hour. It is necessary to test all the main functions (cooling, heating, ventilation, dehumidification, etc.).

Please note! The modes do not switch instantly. It is necessary to wait 5-15 minutes to feel the real changes in the operation of the air conditioner. This is the reason why the testing process takes so much time.

When checking the operability, the device should not emit strange extraneous sounds and smells. Otherwise, it means that mistakes were made during installation. Let’s look at them in more detail.

Errors in the installation of air conditioning systems

If the installation of air conditioners at home ends unsuccessfully, it means that one or more mistakes were made in the process. This situation is familiar to many professionals who come to home masters to correct the consequences of inept installation.

Here is a list of the most common mistakes made during self-installation:

  • When laying the route, the pipes were bent manually and/Or there were too many bends. The work must be performed using a special tool-a pipe bend. The number of bends should not exceed more than one per 1 meter of the tube;

  • Vacuumization was not performed/poorly performed;

  • The wrong type of freon was selected;

  • The connections are not tightened sufficiently or, conversely, excessively strongly;

  • Blocks are mounted without using the building level, there is a horizontal skew;

  • The materials, their dimensions and characteristics were selected «by eye», without making calculations;

  • The outdoor unit is installed on a glazed balcony, in the truest sense of the word. Because of this, the unit does not receive enough air.

These are just the most common problems that specialists face. If you do not have sufficient qualifications, you should not install the air conditioner yourself. Entrust this work to professionals.

Give preference to masters with experience and good recommendations. It is not necessary to involve specialists who are ready to work for a penny and/or can not provide positive feedback from customers.


Air conditioning in a private house has long ceased to be an object of luxury. Now it is the same mandatory household appliances as a refrigerator or a TV. Thanks to the development of technological progress and the reduction in the cost of production, we were able to purchase an inexpensive, but functional split system that can significantly increase the level of comfort.

However, in order to take advantage of all the advantages of the air conditioning system, it must be properly installed. Installing air conditioners is not an easy task. It is not for nothing that individual specialists in service centers are engaged in this.

Therefore, we still recommend that you seek their help after buying the device. Of course, in theory, you can do the installation yourself. But in the absence of proper skills and experience, you risk «getting» money.
