There can be a variety of reasons why an air conditioner doesn't heat well, and here are some common possibilities:
Mismatch between the number of air conditioners and the size of the room: If the room is too large and the number of air conditioners is relatively small, then the heating effect of the air conditioner may not be ideal. When buying an air conditioner, you should choose the right number of horsepower according to the size of the room.
Excessive dust accumulation on the filter: After the air conditioner is used for a long time, a large amount of dust and dirt may accumulate on the filter, resulting in poor air circulation, which in turn affects the heating effect. Therefore, it is very necessary to clean the air conditioner filter regularly.
The vents of the internal and external units are blocked by foreign objects: If the vents of the internal and external units of the air conditioner are blocked by foreign objects, such as dust, paper scraps, etc., it will seriously affect the ventilation effect of the air conditioner, thereby reducing the heating efficiency. These vents need to be inspected and cleaned regularly.
Insufficient refrigerant of air conditioner: Refrigerant is the key substance for air conditioning heating, if the refrigerant is insufficient, the heating effect of air conditioning will be significantly reduced. If there is a suspicion that the refrigerant is insufficient, it needs to be checked and replenished by a professional.
Outside temperature is too low: When the outside temperature is too low, the air conditioner's ability to absorb heat from the outdoor environment is limited, resulting in a decrease in heating efficiency. In this case, the use of auxiliary heating equipment can be considered to increase the indoor temperature.
Poor installation of the air conditioner: If the air conditioner is installed in a poor location, such as direct sunlight, near a heat source, etc., it may affect its heating effect. When installing an air conditioner, one should choose a location that avoids these disadvantages.
Faulty air conditioning system: If there is a fault in the air conditioning system, such as circuit failure, compressor failure, etc., it may lead to poor heating effect. In this case, it is necessary to call in a professional for inspection and repair.
In short, when it is found that the heating effect of the air conditioner is not good, it should be investigated and repaired from many aspects. If you can't solve the problem on your own, it is recommended to ask a professional for service and maintenance.
