Frequently Asked Questions
An air conditioner, like any household appliance, if used incorrectly, can cause harm instead of benefit. To prevent this from happening, it is enough to adhere to a few simple rules:
- The air flow from the air conditioner must not come into contact with people. Since the cold air stream from the indoor unit is directed forward and downward, it is advisable to place the indoor unit on the side of the workplace. The flow direction can be adjusted using horizontal and vertical louvers (vertical louvers are usually not controlled from the remote control, they can only be turned manually).
- If during the day you periodically leave the house, the temperature difference between the outside and inside air should not be too large, otherwise it will be difficult for the body to adapt. At an outdoor temperature of 30 — 35 ° C, it is recommended to set the room to 22 — 24 ° C, but if the temperature outside the window is at 40 ° C, then it is advisable to increase the room temperature to 25 — 27 ° C, although everything is individual here (just watch carefully for your well-being and set the upper limit of the comfortable temperature). Note that when the air is cooled, its humidity decreases, so even at a relatively high temperature, you should not experience discomfort.
- It is necessary to regularly clean the filters of the indoor unit from dust. Before the start of the season, it is recommended to call specialists for preventive maintenance, which includes cleaning the radiator of the indoor unit with special detergents. This will help prevent mold from developing inside the air conditioner.
Most «warm» air conditioners can operate in heating mode only up to -5 ° C. If the temperature drops below, then you cannot turn on the air conditioner — the compressor may fail.
In order for the air conditioner to cool the air normally and not to fail prematurely, it is necessary to regularly (usually every two to three weeks) clean the filters located under the front panel of the indoor unit. In addition, it is advisable once a year, in the spring before the start of the season, to call specialists for cleaning, diagnostics and refueling with freon of your air conditioner.

Air conditioners without an external unit are monoblock air conditioners (mobile and window). There are no other domestic air conditioners without an external unit. In household appliances stores there are so-called coolers that look like mobile air conditioners. Sellers sometimes pass them off as air conditioners without an external unit, however, coolers have nothing to do with air conditioners — they are just air humidifiers with a powerful fan. The first 20 — 30 minutes after turning on such a device, the air can really cool down a little due to the evaporation of water, but then it heats up again, only because of the increased humidity it will become even more difficult to endure the heat.
Household split systems cannot ventilate the air, they only cool or heat it. Window air conditioners can throw out about 10% of the pumped air outside the window, respectively, the same amount enters through the doors or leaks in the windows. For ventilation, you can use ducted air conditioners, which can not only cool or heat, but also take up to 100% of fresh air from the street. However, due to the large size and the need for air duct routing, such air conditioners are rarely used in apartments. For ventilation of air in residential premises, as a rule, compact air handling units are used.
The outdoor unit of the air conditioner generates a large amount of heat, therefore, a powerful fan is installed inside it, which cools the air conditioner evaporator with air flow. That is why the outdoor unit of the air conditioner must be installed in an open space. As a last resort, it can be installed on a glazed balcony, provided that the balcony has several opening windows and one of them is located opposite the outdoor unit fan.
Regular filter replacement helps your heating and cooling system operate at peak levels and improves indoor air quality. It is important to change filters regularly to ensure proper air flow and to keep your home free from dust, allergens and germs. Depending on the type of filter you have, you may require monthly filter replacements.
