Several Reasons Why a Car's Air Conditioning Isn't Cooling?

[JamesAnn]

Refrigerant being too much or too little, compressor damage or aging. Here are the detailed introductions of relevant information: Introduction: In the air conditioning system, the proportion of refrigerant has certain requirements, too much or too little will affect the cooling effect of the air conditioning. If the refrigerant is too little, the amount of refrigerant sprayed into the evaporator by the expansion valve will decrease, thus the cooling capacity of the refrigerant will also drop. Conversely, too much refrigerant will affect its heat dissipation, because more heat dissipation means greater cooling capacity. Compressor damage or aging: The air conditioning compressor is an important component to ensure the normal operation of the car's air conditioning. If the vehicle is relatively old and the air conditioning is not cooling, it is highly likely that the air conditioning compressor has problems such as looseness or aging, affecting the transmission efficiency, thus leading to unsatisfactory cooling effect. It is necessary to check whether the drive belt is broken, and then listen for any noise inside the compressor, these can all be used to judge.
