The air conditioner at home doesn't cool when it is hot, but it cools normally when it is cold?

1. The space where the outdoor unit of the air conditioner is located is very narrow, but the heat can't be dissipated in time, the compressor can't work normally, and the cooling effect can't be achieved. But at night or when it is a little cooler, the heat emitted by the compressor will be neutralized by the surrounding cold air, and the compressor can be cooled without overheating. 2. If you don't clean the outdoor unit for a long time, the surfaces of all components will be covered with dust, which will lead to heat dissipation during work and protect the outdoor unit from overheating.

Treatment method:

1. Move the machine and move the outdoor unit to make it have enough heat dissipation space.

2. Regularly clean the dust or sundries of the outdoor unit. If possible, you can connect a water pipe and directly wash the fan blades of the outdoor unit with water. Adding a little lubricating oil to the rotating shaft of the fan can ensure the normal and efficient operation of the fan and reduce the adhesion of dust.

The daily maintenance of air conditioning is very important. The maintenance and cleaning of air conditioning is the main key to air conditioning maintenance, which can effectively improve the refrigeration effect of air conditioning, reduce the time required for refrigeration, save energy and reduce consumption, and also prolong the service life of air conditioning. However, because the cleaning and maintenance of the outdoor unit is not a simple matter, it is recommended to invite a professional central air conditioning cleaning company to operate it.
