Why Doesn't the Car Air Conditioning Blow Cold Air?
1 Answers
There are several reasons why a car's air conditioning may not cool properly: 1. Insufficient refrigerant due to low levels: The primary cause is usually minor leaks in the system. When there's not enough refrigerant in the AC system, less refrigerant is sprayed into the evaporator from the expansion valve, resulting in reduced heat absorption during evaporation and consequently diminished cooling capacity. 2. Air in the system: The presence of air in the AC system can lead to excessive pressure in the refrigerant lines or poor refrigerant circulation, both of which can cause insufficient cooling. This typically occurs due to deteriorated sealing in the refrigeration system or incomplete vacuuming during maintenance.
