Refrigerant is a fluid capable of vaporizing at a low temperature and therefore used to cool the air supplied by the AC system. In the past, vehicles used R-12 (Freon) before its ozone-depletion properties were scrutinized. Now, vehicles use R-134a, which is much more environmentally friendly.
Symptoms of Wear or Failure
- Air conditioning does not blow cold air

- Some refrigerant leaks can be very difficult to locate. Many shops will inject dye into the system in order to try and pinpoint the leak.
- The proper refrigerant charge (or fill) is critical to proper AC operation
- Only refrigerant recommend by the manufacturer should be used when recharging the AC system
- Due to the high cost of R-12 refrigerant, in some cases, it may be cost effective to retrofit an old R-12 system to use the new R-134A refrigerant
