What happens when Freon is low?
When your AC unit is low on freon, the evaporator coil gets too cold and causes the cold liquid refrigerant to flow back the refrigerant line. This will cause the surrounding moisture on the refrigerant line to freeze up. This is a sign you need freon. You may even end up having to replace the entire AC unit.
What causes low Freon?
Low refrigerant usually occurs because of leaks along the line or in the compressor. The reason is that the indoor coil serves as the evaporator coil, where the refrigerant absorbs heat. With less refrigerant, there is less heat absorption. The coil remains cold, and moisture begins to freeze across it.
Can you add Freon to a golf a / C system?
The A/C system in your Golf consists of a compressor that is belt-driven, an evaporator and freon. If there is a problem with your compressor or evaporator, adding freon will not restore cooling.
