The size of the air conditioner is the indoor unit of a wall-mounted split system. Purpose, design, correct installation and repair of the external unit of a split system. What determines the dimensions of the external unit

Often, during renovations, many people think about installing a split system and plan the design of rooms to fit the size of the air conditioner. Indoor unit of this device it is necessary to place it in such a way that it is not only correctly positioned, but also looks most harmonious in the intended interior.

The purchase and selection of the air conditioner itself is often planned closer to the end of the repair, and the “power” needs to be supplied now. So, this article was written for such cases. In it we will look in detail at what distances need to be taken into account for subsequent installation, and we will identify the most universal sizes of indoor units (wall-mounted household appliances).

First, we would like to immediately warn you that there are “non-standard” models of air conditioners that may have unique sizes and characteristics. And therefore this article should not be taken as 100% universal.

Air conditioner size. Split system indoor unit

More often living rooms have a small area (up to 25 sq. m.) For such rooms, air conditioners up to 2.7 kW are suitable (not to be confused with power consumption) - they are usually called "sevens" or "nines". As a rule, “sevens” and “nines” (of the same model) have the same overall dimensions, as well as the same tube diameter. Therefore, further we will take into account the same dimensions and characteristics of the considered standard sizes.

Overall dimensions of the indoor unit, which interest us primarily

block length. The most standard length of internal blocks is 700-800 mm. Slightly less common are up to 900 mm. By personal experience it is best to take into account average length 770 mm.
block height. Most often these dimensions lie in the range of 250-290 mm. For planning, we will take into account 270 mm.

We are not very interested in depth (170-240 mm). Thus, we have identified the average size of the indoor unit 770 x 270 mm.

Distances from walls and ceiling

Air conditioners “on/off”. We route the cable so that it is subsequently located under the indoor unit ( 300 mm to the left. and below by 100 mm. from the center of the block).
Most

The introduction of new technological solutions in household equipment often runs counter to practical expediency. Example climate control technology most indicative in this sense. So, in Lately The market is actively filling up with devices intended for indoor use. The features of such systems include the complete elimination of dirty installation operations, which attracts a considerable audience of consumers. But despite all the ease of installation and further maintenance, such models are not able to approach the performance characteristics provided by the external air conditioner unit as part of a split system. Another thing is that owners of outdoor installations also have to deal with troublesome tasks, but of a different kind.

What is an external unit?

The outer segment, which is part of the split system complex, includes a condenser, valve decoupling, pipes, filter driers and a fan. Depending on the modification and design, the internal “filling” may change, but a traditional air conditioner kit with a remote unit has exactly this set of elements. By the way, the most noticeable differences are observed in the so-called winter systems, which provide special controllers for controlling the fan. Modern air conditioners also use multifunctional power switching relays. Similar devices designed for non-standard compressor operation under conditions of high or low temperatures. Unlike the internal segment, outdoor unit does not have electronic modules - its operation is completely subordinated to the mechanical function.

Block Dimensions

The outdoor unit is available in the market in different configurations and shapes. And although manufacturers strive to unify model lines in order to simplify segmentation, the choice of standard sizes is still quite wide. If we talk about average parameters, it is 770 mm wide, 450 mm high and 245 mm thick. In this case, the radius of the fan varies on average from 200 to 250 mm. Of course, there are also units whose dimensions deviate from these indicators. Thus, the Mitsubishi line includes an external air conditioner unit of almost square shape, which is 880 mm wide and 840 mm high. As for the parameters of the internal segment, they are not so impressive. Usually these are long narrow modules of medium size - 700 x 200 x 200 mm.

Selecting a location for installing the unit

Usually, when choosing the optimal point for installing air conditioners outside, users are faced with the problem of combining ease of use and protection of the module. For example, the location of the block at height is the best option from the point of view of its safety, but in this case, access to the air conditioner for maintenance purposes becomes more difficult. A good solution would be to place the module on the wall near a window opening or loggia. In this case, other nuances must be taken into account, including the absence of direct rays of the sun and permission for installation from neighbors, since a noisy unit can cause inconvenience to people living on the same level of the building.

In addition, it produces condensation, which will flow down in drops. Accordingly, you will have to negotiate with neighbors on the lower floors. If the installation location of the unit is successfully agreed upon with other residents, you can begin direct installation operations. By the way, another condition for installing an outdoor unit is the possibility of laying communications in the wall.

Installation of the external air conditioner unit

When installing air conditioners, special installation kits are used, which include pipes with flex, brackets with sets of fixing hardware, drainage communications, etc. The physical installation of the segment is carried out using load-bearing components, which are embedded in the walls using anchor elements. At the same stage, brackets are used, the power potential of which is oriented towards the mass of a particular module. Also, the installation of an external air conditioner unit provides for its communication connection with the internal segment. To do this, a hole of the required diameter is made in the wall, which will allow, in addition to the main wiring, to also install a vacuum pump and a pressure manifold. At the final stage, communications are directly connected between the two blocks.

Features of installing the indoor unit

When installing the evaporative unit, that is, the internal module of the air conditioning system, it is especially important to maintain the correct position of the unit. Typically this unit is mounted directly under ceiling surface with a slight indentation. Mechanical fixation is also carried out using suitable brackets. True, in this case the mass of the equipment is not so great, which simplifies the work process. After marking, the master installs anchor elements and, if necessary, fastens load-bearing profiles. Next is installed indoor unit air conditioner with strict adherence to horizontal position. Also, according to the instructions, some models of such segments should have a slight slope towards the passage of drainage.

Maintenance and care

In standard operating mode, every six months the air conditioner should be subjected to service. Most of the work is done with the external unit, which is most susceptible to contamination. Specialists usually check the condition of filters, refrigerant levels, operating pressure module traces, etc. The most difficult operation is replacement working fluid. The refrigerant is a chemically unsafe substance, so it is better to trust its refilling experienced craftsmen. But caring for the remaining components is quite accessible to ordinary users. For example, the answer to the question of how to clean the external unit of an air conditioner is quite simple. First of all, it should be disassembled, after which, using a rag or vacuum cleaner, remove internal surfaces module from dust and dirt deposits. In the process of such maintenance, external filters and heat exchange radiators are cleaned, which extends the service life of the air conditioner.

External unit in multi-systems

The concept of the technical implementation of a split system provides for the possibility of using several indoor modules in one complex, which are serviced by one outdoor unit. Unlike standard configurations, the external module of such a system has engineering differences. For integration into a multi-system, it is equipped with an additional thermostat, which allows you to more effectively control the fan and compressor settings. In turn, the indoor unit of the air conditioner acts as a source of information signals that determine the control of the outdoor module. That is, the user using remote control refers to the panel of the indoor unit, which, in turn, regulates the bypass communications system on the freon line via a digital channel.

Question of price

In modern modifications, split-system type air conditioners are not cheap, which is largely due to the complexity of the design. Even in the entry-level segment, the cost of an air conditioner with a remote unit is rarely less than 20 thousand rubles. Of course, you can also find options for 15 thousand rubles. from little-known brands, but their quality raises doubts both among specialists and among users themselves, who often complain about problems.

Decent quality models are offered by Fujitsu, Daikin, Mitsubishi, etc. The average cost of an air conditioner from the range of these companies varies in the range of 30-40 thousand rubles. At the same time, the most technologically advanced and productive kits can be valued at 70-80 thousand rubles.

Conclusion

The use of air conditioners with a design that requires the installation of a remote unit causes many problems during installation and further maintenance. And this does not take into account the difficulties in transporting equipment. These factors allow us to speak of such units as obsolete. Especially against the backdrop of the proliferation of mobile devices of modest size. However, the external air conditioner unit remains relevant in the market. This is explained by its high performance, functionality and safety during operation, since the main operating units are located outside the living space. And if for household use you can find a low-power replacement for a split system in the form of a monoblock, then in the context of maintenance office premises, public buildings and institutions, multifunctional complexes still have no equal.

Today hardly anyone can live without air conditioning. a private house, apartment, and shopping centers and offices. Split systems are in greatest demand today. This is a type of air conditioner that includes outdoor (remote) and indoor units. Their coordinated work is the key to the proper functioning of the split system.

What does the external unit consist of?

Since the street block is exposed to high and low temperatures, it is subject to increased demands on the quality of workmanship. Its shape, which resembles a rectangular parallelepiped, allows you to place a set of the following parts and assemblies inside the case.

Fan - blows on the condenser, cooling the freon.
Condenser - in it the freon cools and passes from a gaseous state to a liquid.
Compressor is a motor that pumps high blood pressure refrigerant, forcing it to move along the circuit (coil) of the refrigerator.
Four-way valve - it is equipped with air conditioners designed for heating and cooling modes. This part, upon command from the control panel of the indoor unit, changes the movement of freon and, accordingly, cooling in the summer to heating in the cold season.
ECU – this module is installed on the outdoor units of inverter air conditioners. They are less sensitive to temperature fluctuations than devices with non-inverter control.
Bends for connecting tracer pipes connecting the indoor unit with the outdoor unit. Freon flows through these pipes. Like electrical wiring with corrugation, they are protected by a box.
Retaining grille – protects parts and components of the outdoor unit from large objects, debris and insects.
A cover that covers the electrical terminals from atmospheric precipitation.

This minimum set elements without which the circuit is broken and the operation of the device is impossible. The outdoor unit may also contain the following parts.

Voltage regulator - protective circuit electronic and electromechanical elements and components that are particularly sensitive to voltage surges.
Canopy – protects the outdoor unit from precipitation and reduces icing of the housing.
A hose through which water condensate flows. Connect it to the sewer or use it for drip irrigation plantings growing nearby. In winter, when heating and cooling change places, additional heating is used to prevent freezing - the condensate does not freeze into icicles on the body, but drains all away.

To prevent other troubles, install the following on the outdoor unit:

thorns - to prevent birds from landing;
reinforcement cage (this is an anti-vandal grille) - to protect against theft, it is not necessary to install it on the balcony and above the 1st floor;
mosquito net - to prevent poplar fluff and leaves from getting inside the block.

What is it needed for?

Window air conditioners are practically a thing of the past in microclimate technology. They occupied one of the top window openings, and the noise from the external unit in the room was commonplace. Efficiency window air conditioners was much lower, and energy costs were much higher. So, the external unit of a split air conditioner (literally, a divided air conditioning system) is designed to eliminate these shortcomings, namely:

remove the main source of noise and heat in summer (or cold in winter) outside the building, structure, home;
significantly reduce energy consumption and increase efficiency;
simplify maintenance - do not disassemble the entire air conditioner for cleaning, washing and repair at once, but divide the work into 2 fronts.

The disadvantage of a split system is that during installation and maintenance at high altitudes, the customer (and the performing company) cannot do without the help of a truck crane or climbers.

Dimensions

Private individuals - owners of apartments and dachas, for example, are not chasing multi-kilowatt power. If you do not create “autumn cold” in the room from 17 degrees, then a temperature of 21-24 degrees in summer is considered relatively normal for most people. The calculation takes into account the power of the air conditioner up to 2.7 kW. Then the average height of the external block will be only half a meter. The width of the unit is up to 0.7 m, the depth is up to 0.4, taking into account the removal of the device on suspensions at a distance from the wall of up to 10 cm. The dimensions of the external unit of the air conditioner with a consumption of 3.5 kW can reach 55 × 76.5 × 28, 5 cm, however, each manufacturer changes these figures downward.

The weight of the assembled outdoor unit is 12-25 kg. The smallest air conditioner is Ballu BSWI-09HN1. The model does not lack the main blocks and components necessary for high-quality cooling of the air inside the house. It is suitable for a room up to 16 m2 in size, consumes only 900 W when the compressor is running, and maintains a temperature of 21-23 degrees in the summer heat, even if it is 35 degrees outside. The dimensions of the external unit are 70*28.5*18.8 cm. The unit is compact and weighs a little more than a vacuum cleaner. You are unlikely to find a smaller and lighter split system. Produce smaller external split system units postal parcel

there is no point. Micro-air conditioning is already the lot of do-it-yourself experimenters, although the technologies have been developed.

Where to install?

If you live (or work) on the ground floor, then the installation height from the ground is at least 2 m. This will help avoid damage or theft of the unit. Be sure to install the external unit in a welded reinforcement cage with thick (from 1.5 cm) rods. The cage itself must be locked with a massive lock with an anti-burglary mechanism. Its door must have reinforced hinges. On the second and subsequent floors it is not necessary to lock the block behind bars.

On the top floor, in order to avoid calling in climbers or a truck crane (both of which charge an hourly rate for work), some companies place external blocks on the edge of the roof. The maximum length of the “route” (each of the pipes) for the refrigerant is 20 m. A larger height difference between the outdoor and indoor units significantly wears out the compressor. He spends additional energy to overcome the force of gravity acting on the height of the column of liquefied freon. The best solution is to place the external and internal units at the same height. In a private house, the external block is often placed on the facade of the building. This applies to air conditioners of all types, including wall-mounted indoor units.

Installation rules

Without observing the following rules, work installed air conditioner may be significantly complicated or even impossible.

Brackets and brackets are installed with a margin of strength up to several times greater than the strength required for hanging the external unit. Ideally, both fastenings together should support the weight of a person.
The load-bearing wall must be strong and fairly smooth. Uneven walls with old plaster and loose blocks and bricks used for masonry are excluded. Otherwise, the hanging device may fall and injure someone passing by.
On facades with a porous finish, for example, composite soffits on foam plastic, the fasteners are not mounted on the finish itself, but are drilled and cut into the wall (plaster, bricks). This will give suspended structure required strength, inviolability. You can use a basket - a ready-made lattice structure into which the external unit is lowered before connecting to the internal one and the mains voltage source.
You cannot place the external unit of the air conditioner close to the wall - this will prevent it from natural ventilation from the wind. The distance between the rear wall of the external unit and the wall finishing is at least 0.1 m.
The technicians or owner of the air conditioner performing maintenance must have unhindered access to the outdoor unit. Mount the device so that it can be quickly cleaned, prompt replacement worn parts and assemblies.
Do not hang the outdoor unit vertically or slanted to either side. Its horizontal position is set strictly according to the level - this is necessary for uninterrupted circulation of freon in both directions.
The installation location can be a balcony or loggia that is not covered with double-glazed windows. The glazed space will create a locked chamber, where soon the temperature will reach 55 degrees, and the air conditioning will be interrupted - the heat must go somewhere.

The placement of communications also does not contradict the following rules.

The maximum distance between the external and internal blocks can reach 30 m. However, there is a risk of completely losing everything beneficial effect: while the cooled freon travels these 30 m, it will heat up almost to initial temperature. The compressor will run continuously, which can cause it to wear out quickly. Modern split systems, which have protection based on a self-diagnosis module, after useless operation for several minutes, having discovered that the room temperature has not decreased by a degree, simply turn off the power to the compressor and fans of the indoor and outdoor units. The optimal distance is 5 m for each of both pipes, then losses are small.
Copper pipes must be sealed and thermally insulated.
With absence finishing It is advisable to hide the route in the wall. Otherwise, place it in a box. But access to pipe and electrical connections must be present.
It is not allowed to sharply bend the pipes - this will impede the passage of freon.
It is advisable to install a separate line for the air conditioner with a circuit breaker.
Route the hose to drain the condensed water into the drain. It is recommended to install the drain pipeline separately in the walls.
It is recommended not to just start engineering Communication into the wall, and pass them through a special cup holder from the outside.
Hide freon pipelines, electrical cables and drain hoses in foam tubes. Then protect them with vinyl film.
Before pumping in freon, evacuation is carried out using a vacuum pump. It will remove remaining air and prevent freon from turning into exhaust gases, which are less useful. In addition, the tubes are protected from corrosion by vacuum.

The delivery of the installed air conditioner is preceded by a test run and checking the device for freon leaks. No less important indicators– constant freon pressure and regular removal of condensate.

These rules are easy to apply - they are dictated by common sense and are easy to remember.

It is forbidden to push foreign objects through the bars of the cage of the external block, as well as through the curtains of the internal one. Keep children away from the operating device.
Check that room temperature maintenance is turned on at 21-26 degrees. More low temperature during the heat period it can lead to healthy person before a cold - going outside after spending many hours in the cold represents temperature fluctuations of 10 degrees or more, as during a sudden change in weather in the off-season.
Do not allow the air conditioner to operate when open windows. Modern technology does not allow the compressor to overheat and the fans to operate uselessly if the temperature in the room after switching on has not dropped even by a few tenths of a degree. But not all models are equipped with such a “smart” function - low-budget air conditioner models simply do not have it. The device will work absolutely ineffectively, like an old Soviet refrigerator in which the compressor does not turn off around the clock. As a result, all air conditioner motors will fail before the warranty period expires.
Curtain the window on a bright sunny day - excess daylight does not allow the indoor unit to adequately perceive the signal from the infrared LED of the remote control. This or that command is triggered every once in a while - you need to bring the remote control too close to the air conditioner for it to work.
Do not use air conditioning, for example, in the bathroom - excess vapor turns into excess condensation in the indoor unit, which contributes to clogging of drainage and filters.
Regularly turn on the air conditioner purely in fan mode - this will blow out excess condensation.
Clean the indoor unit filters every 2 weeks. It is advisable to wash the external unit at least once every 1-2 months.
Do not place heating or heating devices. Minimum distance – 1 m.
Provide the necessary protection air conditioner from interference sources. The indoor unit should not be adjacent to devices that use radio signals to transmit data and cellular communications. So, do not install nearby 3G/4G modems, routers or Wi-Fi repeaters, the system unit of a home PC, etc. As for the external unit, it is prohibited to place it, for example, near a cell tower and radio relay equipment, if they are located nearby on the roof - the power of their signal is tens of times greater than the radiated power of a smartphone or tablet. Interference from them can reach the processor of the indoor unit and interfere with its operation - especially when the clock frequency of the processor coincides with the side frequencies that are present in abundance near any antenna.

Basic requirements for brackets for installing the outdoor unit of an air conditioner:

The bracket must be strong, but not heavy and can withstand the weight of the outdoor unit of the air conditioner. It must also match the diameter of the holes.
Depending on the weight of the equipment, the brackets must have an appropriate safety margin. The minimum permissible figure is twice the weight of the outdoor unit itself.
Meet GOST requirements for climate control equipment. The material must withstand any temperature regime and have an anti-corrosion and anti-oxidation coating.

Outdoor unit mounted on rectangular brackets

Lately everything larger number Manufacturers resort to making brackets from stainless steel, due to the susceptibility of the metal to corrosion from water on their surface.

The most common types of brackets used when installing air conditioners

Companies involved in the implementation of contracts for the installation of air conditioners use several types of brackets. Among them are the following:

Right angle fasteners made from welded rectangular metal corners 2-2.5 millimeters thick

Rectangular brackets

Brackets of this type are characterized by ease of manufacture, which is why they are cheaper than their thicker and more durable counterparts. However this type fasteners is not quite reliable and suitable for long-term use, since it has a rather small margin of safety. When vibrating, it experiences a strong load, which can damage the protective seam. When anti-corrosion coating will begin to diverge, the brackets will become vulnerable to the harmful effects of water and other particles that can disrupt the integrity metal structure.

U-shaped metal fasteners connected to each other. Like the previous sample, they have a right angle of 90 degrees. The thickness of the material is 2-2.5 millimeters and is fastened with special bolts.

This design is more expensive than conventional rectangular brackets, but it is more reliable. Vibration only applies to connecting element, while the load on the remaining parts of the structure remains minimal. At the same time, galvanized bolts are not subject to corrosion and oxidation. The coating of the brackets reliably resists harmful effects moisture and other atmospheric particles.

U-shaped metal structure with an elongated body, fastened at the bottom with an additional section of channel. The thickness of the metal elements is 2 millimeters.

By the look this design seems to be the most reliable of all presented. Despite the small thickness of the metal elements, the structures can successfully withstand blocks of almost any weight. They do not deform under constant vibration, which guarantees long term bracket services. The coating reliably protects the structure from negative atmospheric influences, preventing deformation, corrosion and oxidation processes in the metal.

Rectangular design of two straight metal corners 2-2.5 millimeters thick

This type of brackets almost completely copies the first sample. The difference between them is that here both corners are fastened together with a connecting metal strip, which significantly strengthens the brackets, allowing them to support blocks of almost any weight. All elements are connected to each other using bolts. The bar lightens the load on the fasteners, and the coating reliably prevents the occurrence of corrosion and oxidation processes due to the negative effects of moisture and precipitation. The connecting strip greatly simplifies the installation of brackets.

All of the above are samples of almost any outdoor units. The size of brackets for air conditioners is traditionally about 40 centimeters in length for the vertical mounting sections.

The choice of bracket for mounting the external unit of the air conditioner should be approached as responsibly as possible. First of all, make sure that the load capacity of the bracket is twice the weight of the outdoor unit. This is necessary because ice that periodically covers the block significantly increases the weight of the equipment.

The holes on the fasteners must match the bolts and other hardware used to secure the brackets. It is strictly not recommended to drill additional holes: this can damage the protective layer of the elements, as well as reduce their load-carrying capacity, which will accelerate corrosion and oxidation processes as a result negative influence moisture and precipitation. But this is also fraught with distortion or collapse of the entire structure under the weight of the external unit of the air conditioner.

And also pay attention to the anti-corrosion coating. Traditionally used enamel, although it reliably protects the metal from the negative effects of moisture and precipitation, loses its properties after a year and a half, which can contribute to deformation and corrosion of the metal structure. More reliable is polymer coating: it penetrates deeper into the material and better protects the metal from corrosion.

Among all anti-corrosion agents, galvanizing of metal is recognized as the best. Experts guarantee that galvanized brackets will last at least ten years. The split system itself can last approximately the same amount of time.

Above we discussed what types of brackets there are and what are their main advantages. A few practical tips will help you purchase a high-quality bracket and make the right choice:

When purchasing brackets yourself, do not forget to make sure that the product itself is certified. By law, the seller is required to provide the relevant documents. If the product is not certified, it is better to refrain from purchasing it - there is a possibility of counterfeit or poor-quality processing. In this case, the reliability of fixation is significantly reduced, which can lead to the collapse of the structure itself and the external unit installed on it
The fastenings must correspond in area to the length and width of the unit being installed. Maximum permissible load should be twice the mass of the block itself, which will protect the brackets from collapse when ice forms on the block itself
Among all the same products, focus on the price-quality ratio. If the block is quite light and the vibration level is low, then regular rectangular brackets will be suitable for you. For heavier blocks, a U-shaped structure reinforced at the bottom will be useful. Here a sales consultant can help you and tell you which type of brackets is most suitable for your air conditioner
The simpler the product, the easier it is to install and the stronger it is. If you are installing the bracket yourself, then a rectangular bracket will suit you, the sections of which are fastened together with a metal strip. These brackets are best suited for those who install the brackets alone

Thus, almost any brackets are suitable for the external unit. The higher permissible level load, the more reliable the design itself. At competent operation the fastenings will serve you for at least ten years, which is comparable to the service life of the split systems themselves.

Which brackets for mounting the outdoor unit of the air conditioner do you prefer?

The principle of dividing the air conditioner into external and internal units in split systems has significantly increased the possibilities of microclimate control. The serviced area of the premises has increased, the power of the cooling and heating system has increased, etc.

The dimensions of the outdoor unit of the air conditioner directly depend on its power.

The higher the power, the larger the dimensions of the external unit, but this should not be taken literally. Manufacturers have developed several standards for the dimensions of the external unit casing, each of which is sufficient to accommodate air conditioner units with a capacity of up to 100%. Going over the upper power limit requires a larger enclosure.

Structural elements of the external unit that determine its dimensions

The main element of the air conditioner, which determines the dimensions of the external unit, is the cooling system condenser, which becomes the evaporator when the unit switches to heating mode. The higher the power of the air conditioner, the larger the area of the evaporators and condenser.

Here it is already observed directly proportional dependence. The condenser area can reach such dimensions that two fans are required to blow it. The dimensions of the compressor, monitoring and control devices, etc. have an influence on the dimensions of the outdoor unit of the air conditioner, but although it is insignificant in geometry, it can be noticeable for the weight of the unit.

When size matters

The size of the external block is great importance when choosing a location for its installation, when, for example, the dimensions do not allow it to be installed in the optimal position from the point of view of installation. The dimensions of the outdoor unit of the air conditioner also remind us of its weight.

Usually in multi-storey buildings install air conditioners with a power of up to 9 kW, at which Weight Limit the external unit weighs just over 60 kilograms, which is quite a lot, and when installing higher-power air conditioners, the weight of the unit reaches 120 kilograms or more. To install such a block, a winch is already required.

Air conditioner high power requires more careful maintenance to prevent the compressor from overheating. Let's give an example. In normal electric kettle With a power of 1 kW, a liter of water boils in 3-4 minutes. When operating an air conditioner with a power of 5-7 kW, it is theoretically possible to boil a bucket of water in the same time. This explains the importance of caring for the external unit - cleaning the surface of the condenser from dust and dirt, especially such as poplar fluff.

We remind you that overheating of the compressor means, at a minimum, additional losses of freon, and in the worst case, it will completely fail when it will need to be replaced and the entire split system repaired. The cost of such work is tens of times higher than the cost of servicing an air conditioner.
