What is the reason why air conditioning heating does not cool?

There may be many reasons for air conditioning heating without cooling. The following are some common possible reasons:

Temperature setting problem: First, please make sure that you set the temperature of the air conditioner correctly. If the temperature is set too high or is quite different from the actual indoor temperature, the air conditioner may not be able to heat. Try to adjust the temperature to the appropriate heating temperature, wait for a while and see if there is any improvement.

Mode setting problem: Make sure your air conditioner is set to heating mode. Some air conditioners have different working modes such as cooling, heating and air supply. Make sure the heating mode is selected correctly.

Outdoor temperature is too low: when the outdoor temperature is low, some air-conditioning models may not be able to heat normally. In extremely cold environment, the air conditioner may automatically turn off the heating function to protect the equipment. In this case, you can consider using other heating equipment to keep the room warm.

Need cleaning and maintenance: Failure to clean and maintain the air conditioner for a long time may lead to failure. Filters and heat exchangers on indoor and outdoor units of air conditioners may accumulate dust and dirt, thus affecting the heating effect of air conditioners. Cleaning the filter regularly and maintaining the air conditioner are helpful to improve its performance.

System failure: If the above methods are ineffective, there may be air conditioning system failure, such as compressor failure, sensor problem or refrigerant leakage. In this case, it is recommended that you contact a professional air-conditioning maintenance technician for maintenance and repair.

Please note that the above are some common reasons, but the specific reasons may be different due to the air conditioner model, use environment and fault conditions. If the problem still exists, please consult professional air-conditioning maintenance service personnel for diagnosis and maintenance.
