What Causes a Car's Air Conditioning to Not Cool?
1 Answers
There are several main reasons why a car's air conditioning may not cool properly: 1. Dirty condenser: The purpose of cleaning the radiator and condenser is mainly for heat dissipation. When cleaning, be sure to first use an air gun to blow away dirt before washing with a water gun. Otherwise, it may have the opposite effect—not only will the air conditioning not cool, but fuel consumption may also increase. 2. Substandard refrigerant and compressor oil: Excessive impurities in the refrigerant and compressor oil can also cause the car's air conditioning filter to clog, leading to poor cooling. This increases resistance and reduces the flow of refrigerant to the expansion valve, resulting in insufficient cooling capacity.
