Useful tips for installing air conditioners. What you need to install an air conditioner. Installing an air conditioner with your own hands: we do the installation according to the instructions in the apartment Selecting a location and installing it yourself

For every apartment owner, installing an air conditioning system in the house is a great joy, because it brings long-awaited comfort to his life, regardless of the weather outside. In order not to overshadow the joy of purchasing an air conditioner, you need to know and follow some useful recommendations that will help reduce to a minimum the number of problems when installing an air conditioner in an apartment.

Who should install an air conditioner?

If a person decides to install an air conditioner in his home, then some practical tips will be presented below to help avoid the most common mistakes. The most important rule is that under no circumstances should you resort to the help of handicraft installers.

Air conditioner installation should only be ordered from the companies from which the air conditioner was purchased. In this case, most likely, you will not be able to save on installation, but fewer problems will arise in the future.

In addition, if the installation of the air conditioner was carried out by the selling company, then the person will receive a guarantee both for the device itself and for its installation. If any units of the system fail, the person who decided to install an air conditioner in the apartment by the seller will have every right to free repairs.

Service maintenance

From time to time, the air conditioning system will definitely need servicing. The simplest type of work, which even a home owner can do, is to clean the air conditioner filter at least once a month.

As for all other types of maintenance, it is better to call qualified workers. Naturally, no one will forbid the apartment owner to do this on his own, but in this case the possibility of warranty service will disappear and, in addition, the quality of the work may be very low.

Ultimately, such self-service can lead to system failure. So it’s better to trust specialists who have experience in such matters and perform service almost every day.

Speaking of complex maintenance work, we mean refilling the air conditioner with freon, which must be carried out approximately once every two years. This will restore pressure in the refrigeration circuit. Moreover, this procedure is carried out directly in the apartment, that is, without dismantling the device.

Which air conditioner to choose

But before installing an air conditioner in an apartment, the owner of the living space must calculate the power of the installed system so that it fully complies with the parameters of the room.

In this case, a calculation is made of all the excess heat that the apartment emits. If the windows of the apartment face south, then you should take care of increasing the power of the air conditioner by 20 percent.

Also, such an increase is necessary in the presence of heat sources. If the power is chosen incorrectly, then the device will wear out, which is why breakdowns can occur quite quickly.

It is also very important when installing an air conditioner in an apartment to choose the right type. If air conditioning is needed for one room, then split systems are used. In this case, the air conditioner consists of outdoor and indoor units, which are connected to each other by communication lines.

If you need to provide air conditioning in several rooms simultaneously, then systems can be used in which there is only one outdoor unit, while there are several indoor units. But in this case, the outdoor unit must have enough power to operate two or more indoor units simultaneously.

It is best to install an air conditioner in an apartment at the time of renovation work. The thing is that installing an air conditioner requires installers to drill the walls, that is, make holes in them through which the outdoor and indoor units will be connected to each other.

So during the installation of freon pipes and other communications, dust and construction debris will certainly appear in the room. That is why it is better to combine the installation of the air conditioner and repair in time.

Conclusion

In conclusion, it is worth noting that the choice of location for installing the air conditioner should be approached very carefully. If you mount it in the corner of the room, then the cold air will not reach the opposite wall. In turn, this will cause a certain discomfort in the person.

Therefore, as with the choice of air conditioner, the installation location must be chosen as rationally as possible. The indoor unit should be placed so that the cooled air from it spreads throughout the room.

It is also very important to install the system correctly, which will be done by good specialists with experience who can provide guarantees for the installation of the air conditioner.

It is best to order installation directly from the company where the air conditioner was purchased. This will allow the apartment owner to solve fewer problems in the future, because with correct and high-quality installation in compliance with all technological standards, they will arise much less frequently.

It is worth noting that if air conditioners are installed, its cost will depend on the size of the inter-block route, that is, the distance between the indoor and outdoor units, on the power of the air conditioning system, as well as on the method of attaching the outdoor and indoor units of the split system.

Installing an air conditioner yourself - for most people, this is akin to launching a rocket into space or the wonders of genetic engineering. But there is a certain contingent, popularly called home craftsmen, who try to do everything in life on their own, some for reasons of saving money, and some for the sake of curiosity.

We strongly support a person’s desire to learn everything new, especially when they can save money, but in order to independently install a split system, you need knowledge and experience, as well as specialized equipment for installing air conditioners. You can not buy it, but rent it, but where can you get experience or rent knowledge? We will tell all those who undertake to install an air conditioner in their own home with their own hands how to do it.

Equipment and tools

Before you think about purchasing a tool for installing an air conditioner, it would be a good idea to study the structure and design features of the split system you have chosen. Maybe after this you will think about the complexity of its design and contact a specialized company for installing climate control equipment. If studying the insides of a split system does not scare you, and you still intend to install it on your own, then first prepare a specialized tool:

• Gauge manifold.
• Vacuum pump.
• Rolling set.

If you managed to get this equipment and learn how to use it, then now it’s worth thinking about and calculating how much it cost you and how much time it took to learn, so isn’t the price of the issue high? If it’s just right, then you need to prepare the rest of the tools for installing the air conditioner: a large hammer drill and an impact drill, a 45-55 mm drill or a concrete bit of the same diameter, a set of open-end and socket wrenches, pliers, a straight and shaped screwdriver, pipe benders, scrapers etc. You will need a mount for the external unit of the air conditioner, 6 anchors for installing it on an external wall, the required quantity, a plastic box for laying pipes, an electrical cable with a cross-section of at least 1.5 mm2, insulation for copper pipes, a foam pipe, vinyl tape, dowel plugs , self-tapping screws. After the copper tube, cable and other consumables have been purchased, calculate how much it cost you, add the cost of renting specialized equipment and think how much you saved if, on average, specialists charge 3000-4000 rubles for installing an air conditioner? And you haven’t started doing the work yet.

Selecting a location and self-installation

Before you start installing the air conditioner yourself, you need to accurately determine the installation location, both the external unit and its internal part. The indoor unit must be installed with a distance from the ceiling of 10-20 cm, and at least 5 cm from the wall to the unit. The internal part of the split system must be positioned so that there is a distance of at least 3 m from the unit to nearby pieces of furniture. This promotes free circulation of air flow throughout the room and its uniform cooling. It will also be a plus for the uniform distribution of air masses. It is best to install the indoor unit on an empty wall, so that it will have the necessary access for periodic maintenance. When installing the external unit yourself, you need to install it on a balcony or under a window. With this installation, you will always have easy access to it. It should be mounted slightly lower in relation to the indoor unit, this contributes to its proper operation. To install it, it is used, which is attached to the wall with anchors.

Important! High-quality installation of the external unit of the air conditioner will help to avoid its strong vibration and, as a result, increased noise during operation.

Self-installation of a split system

1. Marking. Using a level, mark the fastening of the internal unit of the split system. To do this, you need to attach the bracket for attaching the air conditioner to the wall and mark the mounting holes on it.
   

   Important! The internal unit of the split system must be positioned strictly horizontally on the wall, otherwise this may lead to improper drainage of condensate and its flow through the cracks in the device body.

2. Drill holes according to the marks, then insert the dowel plugs and attach the bracket to the wall with self-tapping screws. After installing it, check the correct installation using a building level.
3. Marking the hole on the wall where the freon line is supposed to be laid. An important factor for proper installation is the distance of the route from the indoor unit, which should be 1 m.
4. Using a hammer drill, in the intended place you need to drill a wall with a diameter of 45-50 mm, with a slope of 10-15° towards the external unit of the air conditioner. This is necessary for proper drainage of condensate.
   
   

   Important! When drilling, do not forget about the possible presence of electrical wiring in the wall. Carry out work adhering to all safety regulations.

5. Following the connection diagram, attach a five-core electrical cable to the internal unit of the device.
6. Place the nuts on the copper tubes. To do this, use two adjustable wrenches. After this, the tubes are flared using a rolling set, and then connected to the internal module of the split system.
   

   Important! Do not use grinders or hacksaws to cut copper freon pipes. This can lead to clogged tubes and deterioration in the performance of air conditioning equipment.

7. A PVC drainage pipe with a diameter of 16 mm should be connected to the hose of the indoor module.
8. 
   The external unit of the split system is installed on the prepared bracket and securely fixed with bolts to prevent vibration and displacement.
9. After that, the distance between the block taps is measured, taking into account the bends and turns of the main line.
10. Using a pipe cutter, the required length of copper tube is cut, onto the ends of which nuts are put on and flared.
11. Insulation is put on the copper tubes, after which they, together with the drainage tube and connection wire, are wound into a single whole, a foam rubber pipe is put on them and passed into the prepared hole in the wall.
    

    The ends of the copper and drainage tubes must be immediately covered with vinyl adhesive tape to prevent dirt and dust from getting inside.

12. After passing through the wall, the freon line is connected to the taps of the external unit of the split system.
13. Following the connection diagram, attach a five-core electrical cable to the external unit of the device.

Checking the system and first start of the air conditioner

Before a test run of the system, a vacuum procedure should be carried out to remove air that has entered the system from the tubes and moisture from the circuit. To do this, connect the vacuum pump to the nipple located on the service taps and turn it on. The pump will pump out air, as indicated by the pressure gauge. When it shows a negative pressure value, it can be turned off and the service taps of the freon line can be opened and the first test run performed. http://www.youtube.com/watch?v=pbLqOrHYS1Q

Advice:
Installing an air conditioner in your own home is a labor-intensive job that requires experience and certain knowledge, so trust it exclusively to professionals. This will be the key to long and efficient operation of climate control equipment.

These instructions are given to you as an introduction to the steps and stages of installing an air conditioner. If hot days have arrived, but you still haven’t installed an air conditioner, then try using improvised means. This will help you maintain a good indoor climate.

Remember that installing climate control equipment yourself may cost you additional financial expenses for its repair due to improper installation. Don't take risks and invite professionals to do this job.

• Air conditioner power calculation

Any room that you want to cool has its own parameters, on which the required power of the air conditioner depends. This includes area, volume, and the number of windows, taking into account the cardinal directions they face, and the number of heat sources in the room, and a number of other factors. If something is not taken into account in the calculation, then there is a possibility that you will choose an air conditioner with insufficient power, which will lead to the fact that it will not fully perform its functions, especially in hot periods, or, conversely, you will incur unreasonably high costs due to purchasing and installing a more powerful air conditioner than you need.
As a rule, if it is necessary to cool rooms in standard apartments, the calculation is significantly simplified, however, there are nuances here that are best discussed with a specialist.

• Choosing a brand and type of air conditioner

This is a very important and subtle point. Currently, there are a huge number of different brands on the market, from those that are constantly heard, to a lot of new ones, sometimes sounding very nice. At the same time, the sellers who offer you this product often act as “experts” and strongly recommend some of them. Be careful: sellers are not entirely objective. Their task is to sell the goods they have, so according to them, the best will always be exactly what they currently have in stock.
We recommend that when choosing an air conditioner brand and seller (however, this applies to all household appliances in general), adhere to a few simple rules:
1. Try to ensure that the brand of the product you choose is familiar to you. Beware of buying products, no matter how much they are praised, and no matter how attractive their price (remember the free cheese in the mousetrap!), if you have not heard of such a brand before.
2. It is advisable to purchase household appliances from those sellers whose location you know, and in case of any unforeseen situations it will be easy to find them later.
3. It is better to purchase air conditioners from an organization that can carry out their subsequent installation (then, if dismantling is necessary, for example, for warranty repairs, you will not incur additional costs).
4. When choosing a brand of air conditioner, be sure to ask the seller about the warranty period, the availability of authorized service centers, and where the nearest one is located to you. Practice shows that if an authorized service center is located far away, then when warranty cases arise, problems very often arise with the repair of the repairman - and they demand money (considerable) for the visit, and the journey takes a very long time, and in case of problems with repairs, they may subsequently refuse to do it at all .
5. The least risk in this sense is faced by customers who purchase and install air conditioners in authorized service centers for air conditioners of the corresponding brand, which are also located nearby and constantly work in the area of ​​your residence.

Another important question: what type of air conditioner to choose, regular or inverter? It all depends on the requirements you place on the air conditioner. If you want to get a modern product with a very low noise level, reduced energy consumption and an increased service life, and at the same time you are not very strapped for money, then this is, of course, an inverter. If your goal is to provide sufficient comfort at minimal cost, then it makes sense to choose a conventional split system.
For reference: the main difference between an inverter and a conventional air conditioner is the operating mode of the compressor. If in a conventional air conditioner it turns on and off at the command of temperature sensors, then in an inverter it works continuously, smoothly reducing or increasing its power as needed. This ensures the absence of starting currents and loads, which reduces the overall power consumption, increases the service life of the compressor and makes its operation more silent.

• Choosing a location for the air conditioner

When you decided to purchase an air conditioner, you probably already mentally figured out where you would have it and how it would fit into the interior of your room.
Unfortunately, your wishes are not always technically easy to implement. When choosing a location for installing an air conditioner, for each type you have to take into account some features, for example: for installing split systems, it is desirable, if possible, to minimize the distance between the outdoor and indoor units (route length); It is not possible to hang an external unit on an external wall everywhere - it is advisable to hang it where installation can be done without high-altitude work, where direct sunlight does not fall on it during the day, etc. Therefore, it is best to finalize the location of the individual units of your device with the installation engineer.

• What time of year is best to install an air conditioner?

Many clients, having decided to install air conditioning next year following the hot summer, are waiting for next spring so that the warmth and sunshine will allow them to do this. And with great surprise, when they contact sellers and installers in the spring, they discover a shortage of air conditioners and a waiting list for installation. The time has already passed, even in our country, when air conditioners were exotic and a luxury item. Now they are becoming a necessary attribute of creating normal living conditions for all segments of the population. And they are noticeably turning from a seasonal product into an all-season product. Therefore, there is absolutely no need to wait for warm days. If you decide to buy an air conditioner, do it almost any time. Experienced installation organizations carry out installation at any time (with the possible exception of frost below - 20 degrees) with the same quality and at the same prices.

• Air conditioner maintenance

Have you become the proud owner of an air conditioner? Congratulations! We wish you to fully enjoy the comfort it creates. At the same time, do not forget that this is a complex technical device that, like a car, requires periodic maintenance. It is advisable to do this at least twice a year - before the start of the summer season, in the spring, and at its end, in the fall.
And for those areas where there are a lot of poplar trees, it is highly recommended to carry out a third maintenance after the spread of poplar fluff has stopped. And then you will enjoy coolness without problems for many years.

Who should install an air conditioner?

Who should install an air conditioner? Install it yourself or entrust it to professionals? Anyone who has ever purchased an air conditioner has asked this question. The duration and reliability of the climate control equipment depends on the correct installation of the air conditioner. Often, due to poor installation, the air conditioner fails within the first months of its operation.

So, the model and brand of air conditioner has been chosen, the air conditioner has been purchased, and it’s time to install it. Installing an air conditioner is not limited, like any household appliance, to simply connecting to the network; there are special rules defined in SNiP. Installation of an air conditioner begins with installation. In practice, it looks like this: an installation team comes to you with special tools and various components and assembles your air conditioner. Your air conditioner will serve you faithfully for a long time only if you contact a proven, serious organization with qualified specialists.

When purchasing expensive climate control equipment, buyers often think that installing an air conditioner is not a serious matter, so they turn to little-known companies that claim that installing an air conditioner with them will cost much less than in other companies. So-called “fly-by-night companies” under different names suddenly appear on the market and just as suddenly disappear. Seduced by the low price, statements about the “quality of components” and an eternal guarantee, the consumer also purchases the equipment itself from dubious companies, not realizing the true quality of the “pig in a poke.” By contacting a “one-day company” for the installation of an air conditioner, you are signing a death sentence for your climate control equipment. Pseudo-specialists do not spend money on professional tools, but make do with a minimum number of tools such as pliers or a hacksaw. What kind of quality of work performed and warranty on equipment can we talk about?

Contact companies where the installation (installation) of air conditioners and any other climate control equipment is carried out by qualified specialists who have previously been trained in the installation centers of the largest climate control companies. Professional installation of an air conditioner will significantly save time, money and nerves, and eliminate the need to deal with warranty (post-warranty) service issues. Don't skimp on installation!

Correct installation of the air conditioner

Important details. Ask about the dimensions of the equipment offered. It may happen that in all other respects the air conditioner suits you, but it won’t fit into the interior of the apartment. An important, although often forgotten, point is the coloring of the external unit. Good equipment should have a multi-layer acrylic coating, which is 5-6 times more reliable than conventional paint and protects the device from corrosion. You should inquire about the reliability of different models, the availability of warranty and service. Experts recommend that when purchasing climate control equipment, you should pay not for the number of air conditioner functions, but for its reliability.

Often, customers who want to install an overly powerful air conditioner (or several conventional units at once) in their apartment forget that the home electrical network may not be able to cope with the upcoming load. The consequences of such a rash step are going through the authorities, approving permission to increase electricity consumption, laying cables, additional financial costs, etc. The power consumed is approximately half or a third of the cooling power. For example, an air conditioner with a cooling capacity of 2.5 kW consumes about 0.8 - 0.9 kW of electricity.

It is better to install the air conditioner before or during repairs, because... To lay electrical wiring and install brackets for the indoor unit, it is necessary to chisel and drill the walls of the apartment.

When concluding an agreement with a company for the maintenance and installation of an air conditioner, make sure that the text of the agreement specifies all the services agreed upon earlier, as well as the timing of the equipment installation work. A high-quality installation will cost at least S200-300 dollars. Practice shows that more than 80% of all defects identified in air conditioning systems in recent years are caused by unqualified installation of the air conditioner or other equipment.

Where does installation begin?

For any air conditioner, even a low-power one (from 1.5 kW), it is necessary to install separate electrical wiring and install a separate circuit breaker in the electrical panel. Old wiring may not withstand the load and heat up.

During the standard installation of a split system air conditioner, the following operations are performed: - fastening the external and internal units - drilling holes in the wall - installing freon pipelines - installing a drainage system - installing electrical connections - removing air from freon pipelines - test running the equipment.

Fastening the external and internal units When installing the external unit of the air conditioner, the following points should be taken into account: It is practical to install it on an unglazed balcony. If the balcony is glazed or does not exist, the external air conditioner unit must be installed within reach, because equipment requires preventative maintenance. Otherwise, you will have to call a climber, which is quite expensive.

The surface of the wall must be strong to withstand the weight of the block, and smooth - otherwise the block will vibrate and deform. The external unit of the air conditioner must be installed at a distance of at least 10 cm from the wall, otherwise in hot weather the compressor will overheat and fail.

To mount the external unit, holes are drilled and special brackets and bolts are used. Fastening occurs using a mounting plate strictly level and must withstand a weight several times greater than the weight of the block. Features of installing the air conditioner: Regardless of the height at which the external unit is installed, it is necessary to make a metal canopy over it. This will protect the device from snow and icicles.

On high floors, the outdoor unit is mounted from a machine equipped with a sliding staircase. If installation is carried out above the 5th floor, climbers are called. Such calls are paid separately and cost from $60 to $150. If you live on the upper floors, then the outdoor unit can be placed on the roof. At the same time, the difference between the indoor and outdoor units in height should not exceed 3-20 meters (depending on the brand of air conditioner and model).

When installing external air conditioner units on walls made of sandwich panels (tin, reinforcement and thermal insulation), as well as on the roofs of buildings with metal roofing (corrugated sheets, metal tiles), strong vibration and increased noise are possible. Therefore, it is necessary to plan a separate foundation with special supports and vibration isolators.

When installing an air conditioner in an apartment on the ground floor, you can hang the external unit at a height of 1.8-2 meters above the ground and hide it in a special cage. Installing an external air conditioner unit is a responsible undertaking. During the warranty period, the company that installed the air conditioner bears responsibility for the consequences of falling of a poorly secured unit or unsatisfactory operation.

The indoor unit is also installed on special brackets, which are attached with screws to the wall (if the unit is wall-mounted) or the ceiling (if it is ceiling-mounted). When installing the indoor unit of the air conditioner, there should be no distortions. Otherwise, water (condensation) will flow out of it onto the floor, which, according to installation rules, must be discharged through a drainage tube into a special tank. (Usually the drainage pipe is placed outside or in a sewer).

Places where the indoor unit should not be installed.

• Above any heat source. Otherwise, the air conditioner will constantly work at full capacity and will quickly fail. In rooms where devices with high-frequency electromagnetic vibrations (drill, drilling machine) are constantly used. Their operation can disrupt the settings of the processor installed inside the air conditioner.

• Above the bed or work area (to prevent colds). In places where air circulation will be difficult, such as behind curtains. The distance to the obstacle (wall, furniture, etc.) must be at least 3 meters. Otherwise, the air flow from the air conditioner will be reflected from the obstacle and will return back at the same temperature with which it left the device. Setting the air conditioner will show that the desired climate is set and the device will turn off.

In a standard apartment, when installing a ducted split system, they most often proceed as follows: the indoor unit is hidden under a false ceiling where a high ceiling height is not particularly needed (in a dark room, in a hallway or in a toilet). Air grilles are installed above the doorways leading from the rooms to the common corridor - and there is no need to install a false ceiling in the remaining living spaces. Drilling holes. The holes are necessary for laying inter-unit communications (freon pipeline and electrical cable) and installing a drainage system. For work, a hammer drill with a 45-70 mm drill is used. The holes are drilled with an inclination downward towards the outer wall for unhindered removal of condensate from the pan of the indoor unit.

Installation of freon pipelines.

Pipeline installation is the most important stage on which the final result largely depends. Usually the pipeline is placed in a decorative box or hidden in the wall. In the latter case, appropriate grooves are prepared in advance in the wall of the room. Cutting, bending, cleaning edges and flaring pipes are carried out using special tools (pipe cutters, pipe benders, scrapers and flaring tools). In some cases soldering may be required. Signs of poor quality work in this case are neglect to clean the pipeline from chips, poor-quality rolling, and pipe bends.

It is impossible to bend the freon tubes several times in a small area and unscrew their connections. If the tubes are twisted into a ring with a radius of less than 100 mm, then it will be more difficult for the compressor to pump freon. The consequence of all this will be a freon leak, a decrease in air conditioner power, and compressor failure.

Installation of electrical connections, drainage pipeline.

Indoors, the freon pipeline, electrical cable and drainage hose are usually laid together (in a box or in a groove). It is important that the cross-section of the electrical cable used matches the power of the air conditioner. It is also necessary to remember about grounding, to avoid kinks and ruptures of the drainage hose when passing through holes in the wall and touching bare parts of the pipeline. After laying this “bundle,” the hole in the wall is filled with a heat insulator to prevent water freezing and drafts in the room.

To install the air conditioner drainage pipeline, you must use only a specially designed reinforced pipe. It should bend easily without changing its round internal section, and be perfectly smooth inside. The drainage tube through which accumulated moisture is removed must be inclined at an angle of 5-10 mm so that there is a natural flow of water. If the tilt cannot be done for some reason, it is necessary to install a special pump to forcibly remove moisture.

Violation of technology leads to electrical hazards, melting of the drainage hose, drafts, and condensation entering the room. When diverting drainage into a sewer system indoors, a siphon (water seal) must be installed on the line in front of the drainage discharge point to prevent unpleasant odors from penetrating.

Removing moisture and air from the pipeline.

The air conditioning system pipeline must be cleared of moisture and air, since their interaction with freon negatively affects the operation of the air conditioner. A vacuum pump is used for operation. Neglecting this operation leads to loss of power by the air conditioner, possible failure of the compressor, and a sharp reduction in the service life of the equipment.

Test run of the air conditioner.

At this point, installers should turn on the split system by setting it to a test program. If everything works and the case does not vibrate, then everything is in order. If necessary, the refrigerant is recharged or released.

Operation and preventative maintenance.

For long, trouble-free operation of the air conditioner, certain operating rules must be followed.

Specialists at RostComfort LLC name the following main reasons for air conditioner failure.

1. Contamination of the indoor unit filters. The air filter protects the heat exchanger of the indoor unit, which, when dusty, reduces the efficiency of the air conditioner. Essentially, the air conditioner works like a vacuum cleaner, and the filters act as a dust collector. To clean the filters, simply rinse them in warm water and dry them for a few minutes or vacuum them once every two to three weeks.

If the filters are not cleaned for a long time, the air in the room will cool worse, the operation of the refrigeration system will be disrupted, which can lead to freezing of copper pipelines. In this case, when you turn off the air conditioner, the ice will begin to melt and water will drip from the air conditioner. Cleaning of filters is not included in standard warranty service and must be performed by the consumer in accordance with the requirements of the operating instructions.

2. Freon leak. The second most common cause of air conditioner failure is a normal freon leak. The normalized leakage (about 6-8% per year) always occurs. To compensate, the air conditioner must be refilled with freon every 1.5-2 years. During operation, the compressor is cooled by freon; if there is a lack of it, overheating and jamming are possible. The cost of replacing a compressor is about half the cost of a new air conditioner.

3. Drops in the middle of winter. If you turn on an air conditioner with a drainage pipe leading outside for cooling at sub-zero outside temperatures, the water inside the pipe may freeze, forming an ice plug. Therefore, it is necessary to take care in advance to heat the drainage pipeline to +5° C. For this, use a special cable. If an ice jam does occur, you will have to wait for a thaw without turning on the system for cooling until it warms up.

If your apartment is undergoing renovation, then the installation of the air conditioner should be carried out before the finishing work takes place. In this case, all communications are easily hidden in the wall, and besides, installing air conditioners in a room during the renovation stage will be 1.5 times cheaper than in a finished room.

Some tips for those who are planning to purchase an air conditioner. If your apartment is undergoing renovation, then the installation of the air conditioner should be carried out before the finishing work takes place. In this case, all communications are easily hidden in the wall, and besides, installing air conditioners in a room during the renovation stage will be 1.5 times cheaper than in a finished room. When choosing an air conditioner, it is necessary to correctly calculate its power, taking into account all sources of heat generation.

It is better to install a more powerful model, which is guaranteed to maintain comfortable conditions even on very hot days and extend the life of the air conditioner. Inverter models provide more comfortable maintenance of the set temperature in the room, while significantly saving energy (by several times). When using an air conditioner (with a heat-cold function) to heat a room in the off-season (when the heating is turned off), for every kilowatt of electricity consumed, 3-4 kilowatts of heat are supplied to the room. Think in advance about the place where you are going to install the external air conditioner unit. You should not ask installers to install it on a blank external wall of a 10-story high-rise building. Installation of such a unit will cost much more, and maintenance will generally cause a lot of trouble. The external unit requires cleaning. In such a situation, it is much better to place the external unit of the air conditioner on a balcony or other inconspicuous place. When installing an indoor unit, it is necessary to ensure, firstly, normal air flow to the unit, and secondly, that the outgoing air flow does not enter the workplace or resting place of people.

It is also unacceptable to have any obstacles closer than 2 meters from the outlet openings of the indoor unit. A standard air conditioner can remove up to 2 liters of water per hour from the air, and therefore you need to discuss the nuances of drainage in advance. The best option would be to drain the drainage water into the sewer, but if this is not possible, then it is necessary to remove the drainage to the street. But in winter, it is necessary to ensure heating of the drainage system, which will protect against freezing of water and failure of the air conditioner. Under no circumstances agree to drain condensate into a jar. This not only spoils the interior, but there will also be problems with constant drainage of water. The window air conditioner should not be blocked by blinds or thick curtains. In this case, its performance will drop significantly. If your office or home has PVC windows or double glazed windows, then installing a window air conditioner will be expensive. In addition, the air conditioner will not be able to work as an extractor. You should also remember that when the window air conditioner emits cold or hot air, you should not sit near it at a distance of less than 1.5 meters.

You should inquire in advance about the volume of the condensate collector of mobile monoblocks. If it is small, then you will have to drain the water often, while the air conditioner itself turns off when the container is filled with condensate. The comfortable state of a person is a thing that is difficult to overestimate. Therefore, in order for the air conditioner to please you throughout the entire operating time, you need to choose the option that is suitable specifically for your room.
