What Causes Poor Cooling Performance in Sedans?

[Francis]

Poor cooling performance in car air conditioning may be due to insufficient refrigerant; excessive refrigerant; clogged filter screens; air entering the air conditioning system; or insufficient heat dissipation capacity of the condenser. Below are solutions for car air conditioning not cooling properly: 1. Clean the radiator and condenser: The radiator and condenser can be rinsed with a water hose at home, but avoid using a high-pressure water gun as the condenser is made of very thin aluminum material, which can easily be deformed by high-pressure water. If they are too dirty, it is recommended to go directly to a 4S shop for cleaning. 2. Replace the air conditioning filter: It is recommended to replace the air conditioning filter once a year, but check it every six months. 3. Check if the air conditioning lacks refrigerant: If there is a shortage, simply refill the refrigerant and check for any leaks.
