What Causes AC Blowing Warm Air With No Freon?
What the customer reported
The vehicle owner reported that the AC was blowing warm air.
What we found and did
The technician found the AC system had 0.00 lbs of freon. At our Sebring shop, the team connected AC equipment, evacuated the system, verified system pressures, then charged it with R134A refrigerant and the proper oil capacity. The system was leak tested and UV dye was added so any leak can be traced with special UV glasses if the vehicle blows warm again. The shop told the owner to return if that happens, at no charge, to have the leak evaluated again.
