How do you know when need more Freon in your car?

Freon is no longer used in automotive air conditioning systems. It was phased out in the 1990s due to its ozone depletion potential. Current automotive air conditioning systems use refrigerants such as R-134a, which are more environmentally friendly.

If your car's air conditioning system is not cooling properly, it is likely due to a refrigerant leak or some other issue with the system. Have the system inspected by a qualified technician, who can diagnose the problem and recommend the appropriate repairs.
