How to choose air conditioning for an apartment and a house: what to look for Attention

When choosing an air conditioner for an apartment, house or office It is recommended to pay attention to the following parameters:

  1. Type of air conditioner;

  2. Power (including the amount of indoor air that the device able to condition);

  3. Available operating modes;

  4. Noise level;

  5. Power consumption level;

  6. Additional functionality (drainage, ventilation and etc.).

Of no less importance is the manufacturer air conditioner.

Types of air conditioners

Structurally, according to the principle of operation and installation method air conditioners are divided into the following types:

  1. Window;

  2. Floor standing;

  3. Wall split systems;

  4. Channel.

Window air conditioners

Window air conditioners

Window air conditioners are one of the easiest to install, and the functionality of the options. As the name implies, they mounted directly in the window opening. When turned on they pump air from the street while heating or cooling his.

The design of such air conditioners includes a single unit, in which all functional elements are installed: compressor, refrigerator, etc.

Like most other mid or budget air conditioners class (and the windows belong to it), they can work on cooling or heating the room, and additional functionality determined by the type of filter installed. These components may to be coal with a high degree of purification, antibacterial with disinfecting effect, washed with reusable, etc.


  • Easy to install. You can even install yourself with certain skills and a compatible window framing;

  • Easy to operate. Service procedures such as replacement filter or cleaning, you can do it yourself;

  • Long operational period. With proper care window air conditioning can work for several decades;

  • Low price. Often much lower than other air conditioners types;


  • High noise level. Since the compressor is, in fact, in the indoor unit, his work is very audible;

  • Inability or very high complexity of lead organization moisture. Condensed water from the air conditioner drips directly from the conclusion to its outer part. Because of this, organize her abduction can be very difficult.

  • Violation of the integrity of the window opening. Often air conditioning It is located in the frame loosely, without adhering to the walls. it leads to the fact that in the cold season low temperature with the street enters the room;

  • Air conditioning occupies a usable window opening area. it leads to a decrease in the amount of penetrating into the room Sveta;


All this makes a window air conditioner a good option. exclusively for places with mild winters.

Floor air conditioners

Floor air conditioners

Floor air conditioners come in two types – with and without air duct him. Structurally, they are a mobile unit in which, according to analogy with the window, built-in compressor, refrigerator, filter and other function blocks.

The duct is a system of channels in the walls of the room. By hot air is removed from the air conditioner and is “thrown out” on the street. This is the main disadvantage of such devices – the hot air exhaust system must be installed at the stage construction or decoration.

An alternative is to install a duct in a window opening. Then a tube system is not required.

Floor air conditioners without duct air conditioning, in fact, are not. These are rather humidifiers, which are additionally heat up the room. Due to their action, subjectively seem to have become cooler in the room, however objectively the temperature does not decrease. In addition, humidification can cause discomfort in people with diseases cardiovascular or respiratory system.

Some models of floor air conditioners without duct still cool the air by passing it through briquettes of ice. But this also leads to increased humidity in the room.

Therefore, using floor air conditioners, it is better to choose models with air duct.


  • Mobility. They are located only in the room, which required to cool;

  • Easy installation of the duct in the window opening (if the system tubes in the room is not used);

  • Possibility of easy replacement. In the event of a breakdown, it is enough to purchase only a new mobile unit, the air exhaust system is being repaired does not need (except if it is clogged);

  • The absence of cold flows in the upper area of ​​the room air. This protects against “blowing” and diseases caused by it. Air convection occurs naturally;


  • Low productivity. Indoor air cooling requires some time;

  • The need to organize the duct – either in the form of a system tubes, or in part of the window;

  • The need for manual removal of condensate. Periodically capacity they need to be cleaned with it – and the more often, the better, because in a humid environment, bacteria can develop;

  • Large dimensions of the main unit. It is similar in size to bedside table;

  • High noise level. Similar to window air conditioners, the compressor – the loudest part of the device – is located in indoor unit;

  • Pumping part of the air out of the room. Especially critical for rooms in which fresh air for one reason or another is not comes;


Floor (mobile) air conditioners are just an alternative for full split systems, but not fully functional devices for cooling the room.

Wall split systems

Wall split systems

Split system, as the name implies (split translated from English – “separate”), consists of two blocks. Main the air conditioner module in which the refrigerator is installed is located on the outside wall of the house. Additional, with compressor, located directly in the room and is designed to output chilled or heated air.

Split system modules are connected by one or several tubes, through which hot air is vented or cold is pumped. These channels are laid through the wall, resulting in installation air conditioning becomes quite difficult, and in some cases also requiring permission from the management company (if property rights to the facade of the house are issued on it, for example).

However, split systems are the most productive and functional variety of air conditioners. They are not only fast cool the room, but also able to heat it. And in some models also have humidity and cleanliness control modes air.


  • Highest performance for fast room temperature control;

  • Optimum price (models that are designed exclusively for cooling, can cost about several thousand rubles. At that same time, multifunction devices are different high cost);

  • Advanced functionality;

  • Minimum noise level;


  • Complex, and in some cases problematic, installation of an external block;

  • The need for periodic qualified technical maintenance, including cleaning and repair of the cooling system.

  • Lack of mobility – the indoor unit cools or warms up only the room in which it is installed;

  • Increased power consumption;

  • The need for punching walls for laying pipes and cables;


Despite the above disadvantages, wall mounted split systems are the best solution for effective protection against high temperature outside.

Duct air conditioners

Channel air conditioners

Ducted air conditioners are functionally a kind of split systems. The key difference is that to the system is connected to the internal block of such a device ductwork. It is on them that the cooled air is distributed throughout rooms – several rooms, offices, etc.

Since ducted air conditioners involve the use of duct systems, their installation should be designed at the stage construction or overhaul of a house or apartment. Tubes with exits can be placed in walls, under suspended ceilings or in special niches.

The main advantages of this air conditioner are the lack of noticeable indoor unit and the possibility of cooling (or heating) several rooms at once. And the drawback is the highest complexity installation – you need to allocate a separate room for placement functional elements and lay ducts.

Duct air conditioners are usually designed for use in large buildings with high traffic – office centers, restaurants, hotels – therefore, in the vast majority of cases have high power.


  • Possibility of cooling and supplying fresh air at once several rooms;

  • Low price when used in large office centers, homes, other large rooms with many rooms;

  • High performance;

  • Lack of indoor units in refrigerated rooms;


  • The impossibility or high complexity of climate control in separate rooms;

  • High power consumption;

  • The need for regular professional maintenance, including canal cleaning;

  • The high cost, making it impractical when used in apartments or private houses;

  • High complexity of installation, resulting in the placement of channel air conditioning must be planned before repair;


All this makes ducted air conditioners an appropriate solution. only for use in large buildings with a large number premises.

Which air conditioner to choose

Which air conditioner to choose

When choosing an air conditioner, it is worth starting from planned conditions of use and structural features in which it will be set.

  1. If the main requirement for the air conditioner is ease of installation, then you can use window models or floor with a duct, which throws hot air directly out the window.

  2. If the house already has a duct system, good the solution will be a mobile floor air conditioner, which connects to existing channels.

  3. If the main requirement is productivity and wide functionality – a complete solution will be the ideal solution split system. It is she who quickly cools or heats the air in indoors. In addition, many models of modern split systems require minimal interference with the wall structure.

  4. If you plan to install a single air conditioner in a large private or an apartment building, office space or similar structure, a good solution is the channel.

The main criteria for choosing an air conditioner

When choosing an air conditioner, the following parameters should be considered:

  1. Productivity (in terms of capacity or volume for which rated air conditioner);

  2. Power consumption level;

  3. Noise level;

  4. Operating modes;

  5. Extra options.

Air conditioner performance

Air conditioning performance – a parameter that determines at what speed or efficiency can the device cool to heat the air in the room. It is influenced by two characteristics – directly the power of the device and the volume of air to which it calculated.

Air conditioner power is measured in watts. The higher it is, the faster, the device cools (or heats) the air in the room. But at the same time, both energy consumption and level increase. noise of the air conditioner, which is especially critical for window or floor models.

Technically, air conditioning power is a pretty concept fuzzy because manufacturers often indicate no direct compressor power, and system power cooling. It is much higher than consumed. So, in the air conditioner with a cooling system of 4 kW installed, most likely 1.3 kilowatt compressor and actual consumption also is 1.3 kW (or a little more for the rest functional elements).

For home use, it is worth choosing air conditioners with power of the cooling system up to and including 4 kW (up to 1.3 kW compressor consumption, respectively). Similar devices may join the household network without changing or withdrawing it additional load channel. More powerful air conditioners preferably included in a separate line for power protection the rest of the house.

Nominal air volume

Nominal air volume – more practical for power rating air conditioner option. It shows how much (in cubic meters) of air the device can cool or heat at optimal load. It is calculated as follows – it is necessary to take the area of ​​the room or adjacent rooms, where planned to install air conditioning, and multiply by height the ceilings.

When using the air conditioner in rooms with a larger volume rated for which the device is designed, it will work with increased load, which can lead at best to inefficient cooling (heating), and at worst – to breakdown compressor or refrigerator.

Therefore, choosing an air conditioner is primarily based on volume of the room.

Air conditioner power consumption

Power consumption of the air conditioner

The power consumption of the air conditioner is directly dependent on the actual power of its compressor and usually makes about 110-120% of it values. In models with a heat pump, this value may still be higher.

To reduce power consumption, it is recommended to purchase inverter air conditioners. These are devices with automatic by adjusting the intensity of the compressor. Inverter air conditioners consume the most electricity at the start (immediately after turning on or changing the set temperature), and subsequently become very economical, because for maintaining selected microclimatic conditions do not require continuous operation of the compressor.

Energy efficiency indicators for air conditioners are EER and COP parameters. The first shows the system power ratio cooling to actual power consumption; the second is attitude heating system capacity to actual power consumption. Both of these parameters has a letter scale of notation in which the letter A shows the highest energy efficiency, and the letter G – the smallest. It’s self-evident that it’s worth buying air conditioners whose EER and COP parameters are in the range A-C.

Noise level

The noise level depends on two parameters – the power of the air conditioner (the higher it is, the louder the technique works) and its location “external unit” with compressor. So, in window and floor devices, the compressor is located in the indoor unit, and therefore, when they make quite loud noises at work. Split systems and channel air conditioners are equipped with a full external unit and therefore have low or even zero noise level.

The vast majority of household air conditioning performance cooling systems up to 3 kW have an external unit noise level of up to 55 dB – this corresponds to the volume of ordinary human speech. Besides Moreover, such a volume is allowed by sanitary standards, including European and Russian for the dark.

The lower the noise level, the better. Especially for indoor unit split systems. Its noise level for comfortable use must not exceed 20-30 dB, otherwise may be observed physical problems (up to the appearance of headaches pain).

It is understood that desktop and window air conditioners have more high noise level – up to 40-50 dB. Therefore “loud” devices should be used periodically, just cooling room on and off for the night.

Operating modes

Operating modes in general approximation are of two types – cooling and air heating. And if you lower the temperature in the room can air conditioners of all models, only some increase it. This is due to structural differences.

If in cooling air conditioners to create a microclimate only a refrigerator is used, then in heating – also a heating element (tubular electric heater) and heat pump. All of them designed to increase air temperature and, depending on designs, can be located both in external, and in indoor unit.

Air heating mode – optional for air conditioners or split systems. Therefore, if such a device is required exclusively cooling, you can get by with models that don’t equipped with a heating element.

Additional features of the air conditioner

Additional features of the air conditioner

In addition to cooling and heating the air, some models air conditioners are equipped with additional functionality. Among such opportunities may be:

  1. Air drainage;

  2. Ventilation mode;

  3. Air cleaning;

  4. Air ionization;

  5. Airflow direction adjustment;

  6. Work timer;

  7. Smartphone remote control and smart features.

Dehumidification mode

Drying the air in the room allows you to make the microclimate more comfortable and environmentally friendly – in a low humidity environment pathogenic bacteria develop more slowly. Almost all air conditioners and split systems during normal operation (mode cooling) also reduce air humidity. However some models are equipped with a dehumidification function without cooling, which can be use in autumn and winter.

Drain mode – the function is quite useful, but only in that case if you really need it. That is, regularly required reduce humidity – for example, in the bedroom, especially if it contacts with a bathtub or a bathroom.

Ventilation mode

The ventilation mode is designed to create an influx of fresh air from the street without cooling or heating it. If air conditioning planned to be installed in a room with no windows that open, very It is recommended that it be equipped with this feature. Also she will be useful in the cold season, when natural ventilation may cause discomfort.

Air purification mode

The air purification mode is similar to the ventilation mode, but in this in case the air conditioner drives through the built-in filter system air that is present in the room. Due to this is reduced level of dust and other pollution.

The usefulness of the air purification mode is directly affected filters installed in the air conditioner and their “freshness”. So with factory filter system only removes from the atmosphere mechanical pollution like dust. The carbon filter also cleans at the chemical level, and antibacterial – disinfects.

Very rare air conditioning models produced by treating it with ultraviolet radiation. This does not remove mechanical suspensions, but it is effective disinfects the atmosphere.

If the air conditioner is equipped with a cleaning mode, it is very important change filters regularly and flush the storage tank condensed moisture.

Air ionization mode

The air ionization mode is similar to the cleaning mode, but in this case it is enriched with ions – by passing through carbon filter or special ionizer. Thanks to this air it becomes noticeably fresher (up to the feeling of “mountain”), and also purified from pathogens.

Air conditioners with ionization mode should be used in houses where there are elderly, children and people with reduced immunity. In addition, they can be used simply to improve the microclimate. This is especially important in urban environments where ventilation through windows it can only worsen the organoleptic qualities of air.

Airflow direction adjustment

Airflow direction adjustment via movable divider, which is located in the outlet air conditioner. This function is equipped with almost all modern split systems. Direction adjustment mode allows either faster cool the air in the room thanks to artificial convection, or get rid of drafts and the risk of “blowing”, which is especially important, if the air conditioner is located in close proximity to work or sleeping place.

Work timer

Work timer allows you to automate shutdown air conditioner. It can be implemented in two ways. First and the most popular is the automatic shutdown of the air conditioner after expiration of a certain user-set time. The second option is to stop cooling or heating upon reaching set temperature.

Both of these options have both advantages and disadvantages.

Air conditioners with the ability to set a timer


  • There is no risk of forgetting that the air conditioner is on and thereby freezing either overheat the room;

  • The risk of compressor wear and refrigerant leakage is reduced;

  • You can set the air conditioner on the timer and go to bed – through for a while it will turn off and stop cooling the room;

  • You can significantly reduce power consumption;


  • The air conditioner may turn off before being indoors a comfortable or just suitable microclimate will be established;

  • You need to constantly reset the timer, setting the time or work temperature.


Thus, a timer is a useful function, but only if if the flaws are not critical.

Smartphone Remote Control

Smartphone remote control and other smart features found mainly in the most modern models air conditioners. This, in fact, is not so convenient because in in most cases both devices need to be in the same wireless network. Therefore, setting the air conditioner can carry out only in the house – and the smartphone in this case acts just a replacement for the remote.

However, various “smart” functions allow detailed set the temperature and operation mode, as well as the on timer – so that the air conditioner refreshes the air in the room at the arrival the owner.

Smart features make air conditioning just more convenient and do not determine its capabilities, so purchase climatic devices with a similar control mode costs desire.

The cost of air conditioners

air conditioning prices

The cost of air conditioners is determined not only by their type, but also functionality, as well as power and other operational parameters. Also, offline retailers may optionally increase the price of the device, adding installation services to it or maintenance.

  1. The price of window air conditioners starts from 8-10 thousand rubles. However, the vast majority of models are in the price a range of 20-30 thousand rubles.

  2. The price of ducted floor air conditioners starts at 10-12 thousand rubles. Similarly windowed, the vast majority models is in the price range of 20-30 thousand rubles.

  3. The price of a split system starts from several thousand rubles. The vast majority of models are in the price range of 15-35 thousand rubles, the cost depends on capacity, performance and other specifications.

  4. The price of ducted air conditioners without mounting an air duct system starts from 30-40 thousand rubles, but the vast majority models are in the price range of 100-150 thousand rubles. The cost depends on the power of the device.

The best manufacturers of air conditioners – which company to choose

Among the manufacturers of air conditioners, there are companies whose products are characterized by maximum reliability:

  1. Daikin, Mitsubishi, Toshiba, Fujitsu – already recommended Japanese manufacturing companies. Air conditioners from these brands are quite average in price, however, it is fully justified by quality and operational device characteristics;

  2. Haier, Ballu – Chinese manufacturers of air conditioners. Them climatic technology are relatively low price and at this is very high practicality, as well as durability;

  3. LG, Samsung – Korean manufacturers. Their technique is most often equipped with the latest technological solutions, but refers to the middle or top price range.

  4. In addition, it is worth highlighting Hitachi. Her technique is usually expensive, but very high quality.
