What to do if the air conditioner does not cool well and blows hot or warm air

Cooling is the main function of climate technology. The question "why does not the air conditioner cool?" very often sounds in service centers. Sometimes the owners can cope with the problem on their own, but in some cases they have to resort to the help of professionals. There may be several reasons for the malfunction, we will analyze the main ones, as well as the actions of the owners when the air conditioner does not cool the air.

Clogged air filters

There seems to be coolness coming out of the case, but the air conditioner does not cool the air? This is a reason to immediately clean the air filters of the indoor unit. If this is not done in time, the air conditioner may break down.

The outdoor unit works in an even more difficult environment: dust, cobwebs, tree fluff, moisture effectively clog the gaps between the evaporator plates. Here, the heat taken from the room is given off to the atmospheric air. But if the evaporator is clogged, the process is disturbed, the air conditioner blows warm air. The air is simply driven around by fans.

Owners who service the equipment on time are not faced with why the air conditioner blows warm air. Some models independently signal the owners about the need to clean the filters.

Not enough refrigerant

This is the second most common cause of poor air conditioning cooling. In a perfectly assembled system, 4 - 7% of the refrigerant evaporates per year. But if the slightest mistakes are made in the installation, the figure increases significantly. Therefore, add refrigerant to the air conditioner. This procedure is carried out by specialists. It is necessary to select exactly the freon that is in the system.

Not enough power

Even a properly sized model may not cope with cooling on particularly hot days. And if the windows face the sunny side, the heat flow increases significantly and the air conditioner does not cool well.

To solve the problem of poor cooling by the air conditioner, you can reduce the flow of heat. Cover the windows with blinds, reduce the number of household appliances in operation, close the vents.

If the air conditioner does not cool well, and after a while the compressor stops, it is necessary to turn it off and urgently call the masters.

In this case, the answer to the question: "why does not the air conditioner cool?" lies in the state of the compressor. He needs repair or even replacement.

Masters with special devices will be able to identify the reason why the air conditioner does not cool well.
