It's too hot. What's wrong with the air conditioner not cooling?

The reason why the weather is too hot and the air conditioner does not cool: it may be that the filter screen is blocked and needs to be cleaned immediately; Or the room area is too large and the air conditioning power is too small. It is suggested to replace the air conditioner or increase the wind speed in the early stage of refrigeration; It may also be that the temperature around the outdoor unit is too high. It is suggested that the outdoor unit should be installed in a backlit and unobstructed area, and the effects of rain, sun and dust can be achieved by installing a range hood.

The answer is applicable to air-conditioning models of most brands such as Gree, Haier and Midea.
