What are the reasons why air conditioners don't cool at high temperatures?

There are four reasons why air conditioners don't cool at high temperatures:

1. Wrong type selection

The number of air conditioners does not match the room area, or there are heat sources in the room, and the glass room is exposed to sunlight, which will lead to poor cooling effect.

2. The external environment temperature is too high.

If the outdoor unit is installed in a relatively closed space or the temperature around the outdoor unit is too high, the air conditioner can't dissipate heat normally, resulting in poor cooling effect of the air conditioner.

3. Overheating protection of air conditioning compressor

The temperature of the outdoor unit of the air conditioner is too high, far exceeding the heat dissipation capacity of the condenser. At this time, the compressor will be overheated and cannot be cooled normally.

4 indoor long time without cleaning.

If the indoor unit is not cleaned for a long time, the filter screen and evaporator of the indoor unit will accumulate dust, which will affect the refrigeration effect.
