Problems with air conditioning: blowing warm air at the outlet of the air conditioner, weakly cools or does not cool at all

Why does not cool the air conditioner?

A complaint about the temperature at the outlet of the air conditioner is the most common in service centers. Another common malfunction is the warm air blowing from the air conditioner.

How to check if the air conditioner cools well?

The most important indicator is the air temperature released by the inside of the device. Its indicators should be within 6-14 degrees above zero. The reason that the air conditioner cools poorly may be a large amount of dust deposited on the heat exchangers from the outside air temperature, as well as from where the air conditioner is manufactured. Air conditioners produced in Japan or the Old World cool less than those made in China.
