Installation of an air conditioner on a ventilated facade

Installation of an air conditioner is a complex multi-faceted topic that causes serious disputes among masters and owners of split systems. But the issue of mounting the device on a ventilated facade deserves special attention. Often this task puts the masters at a dead end, because it is unclear exactly how to fix the outdoor unit, whether the plates will withstand such a load.

In this article, we will tell you in detail how the air conditioner is installed on a ventilated facade and what nuances should be taken into account. Read other articles on our website. We have a lot of useful materials dedicated not only to the installation, but also to the operation of air conditioning systems.

General information

The most common type of air conditioner is a split system. It consists of an outdoor and an indoor unit. The indoor unit is mounted indoors, so there are usually no difficulties with it. Usually, problems begin at the stage of installing the outdoor unit. It is mounted outside the building. And if the house has a ventilated facade, the installation of the unit may be difficult.

What the masters do not come up with… Someone even manages to remove part of the ventilated facade, opening the insulation for everyone to see, and install an air conditioner. At the same time, the insulation remains open to the weather and, moreover, noticeably spoils the facade of the building.

To avoid this, it is necessary to take into account a number of nuances. Next, we will talk in detail about the installation of the outdoor unit and about the key features.

Details about the installation

The installation of an air conditioner on a ventilated facade of a building always begins with the correct selection of a place. We recommend mounting the outdoor unit directly under the window or loggia. So it will be easy to maintain it.

When choosing a place, pay attention to the side: it is not recommended to mount the outdoor unit on the western or southern side. Ideally, it is better to put the air conditioner on the north side.

When removing the drainage pipe, it is important to make sure that the condensate will not drain onto the windows or the balcony of the neighbors. And even better, if the excess water will drain immediately into the sewer and a siphon for the air conditioner will be used.


You need to prepare the tools in advance. The work will be performed at a height, so it is important to have at hand all the necessary set of materials and consumables.

For installation, you will need:

  • Puncher;

  • A set of drills of different diameters;

  • Pump;

  • Rolling machine for pipes;

  • Pressure gauge;

  • Copper pipes;

  • Level;

  • Pipe Bending machine;

  • Anchor bolts (length 10-15 cm).

Mounting of the outdoor unit

After choosing a suitable place, make a markup. You must understand exactly where you will attach the bracket for the outdoor unit.

Use the construction level to mark the horizontal line. Draw a perpendicular vertical line from one edge. At the intersection of these lines, there will be a mounting point for the first bracket. After that, it is necessary to draw the same second vertical line, taking into account the size of the block. At the intersection of the lines, a point is formed for attaching the second bracket.

Next, using a puncher, you need to drill two holes: at the intersection of the lines. I.e., you should get two holes. The diameter of the hole should be slightly smaller than the diameter of the anchor bolts. The depth of the hole should be such that the anchor goes directly into the wall, through the ventilated facade and insulation.

Please note!

The brackets should not be installed on a heater or on another unstable base. At the installation site, it is necessary to cut out part of the insulation, but it is important to do it carefully. Do not cut out too much thermal insulation, otherwise the wall will freeze in this place. Do not forget to install it in place after removing the facade plate.

Additionally, one more hole is drilled at a certain distance from the intended installation location of the unit. Communications will be output through this hole. The recommended diameter is 50-80 mm. If the walls are made of brick, it is easier to drill a seam than to try to break through the masonry.

Now you need to fix the brackets on the facade. The anchor bolts must be tightened with maximum force. Before that, it is advisable to check the horizontal and vertical lines, using the same building level.

It remains to hang the outdoor unit. The optimal distance from the block to the wall is not more than 10 cm and not less than 8 cm, block is securely fixed. The horizontal is checked again. There should not be a strong skew.

Laying the highway

To lay a highway, you need to first proshtrobit the wall. Before laying, the pipes are carefully insulated, or you can immediately purchase heat-insulated tubes. The pipes are bent in the necessary places. The work can be done manually, but we recommend using a special tool to avoid creases.

It is better to immediately add 60-100 cm to the total length of the highway. In this case, it is better to overdo it a little, so that you do not have to build up the tubes and do soldering later.

The pipes are rolled, and the main line is connected to the fittings in the outdoor unit. The track is brought out to the street through a hole in the wall. A drainage tube is also output through it, which should later be connected to the drainage system of the indoor unit. Next, it is necessary to perform vacuumization.

After vacuuming, the system is filled with freon and tested. Usually, an hour or two is given for tests. This time is enough to check the operability of all the main operating modes.

It remains to close all the cracks in the wall. This can be done with the help of mounting foam or sealant. The strob is plastered, then a finishing finish is made.


Installing a split system on a ventilated facade is not as difficult as it may seem at first glance. The main thing is to follow simple rules. Try to do the work carefully, and do not forget to put the facade plates in place so that the building looks as beautiful as before installing the air conditioner.

Use high-quality anchors and a construction level. The air conditioner must be installed with the correct horizontal and vertical position. If the insulation prevents you, cut out part of it, but do not get carried away. Otherwise, the wall may start to freeze.

Also, do not forget to seal all the cracks formed after installation. Otherwise, the wind will start blowing through them and the residents will be uncomfortable indoors.
