What are the reasons for poor cooling effect of car air conditioning?

[MacEden]

Poor cooling effect of car air conditioning may be due to insufficient refrigerant; excessive refrigerant; clogged filter screen; air entering the air conditioning system; insufficient heat dissipation capacity of the condenser. Here are the solutions for car air conditioning not cooling: Clean the radiator and condenser: The radiator and condenser can be rinsed at home with a water hose, but never use a high-pressure water gun, as the condenser is made of very thin aluminum material and can easily be deformed by high-pressure water. If it is too dirty, it is recommended to go directly to a 4S store for cleaning. Replace the air conditioning filter: It is recommended to replace the air conditioning filter once a year, but check it regularly every six months. Check if the air conditioning lacks refrigerant: If it lacks refrigerant, simply add some, and also check for any refrigerant leaks.
