AC Still Blowing Hot After Two Recharges This Year
What the customer reported
The vehicle owner reported that the A/C was still blowing hot after two recharges this year at another shop. They were not sure whether dye was used on the last recharge.
What we found and did
The testing showed the A/C system uses R-1234YF refrigerant but had at some point been introduced to R-134 refrigerant, so the contaminated refrigerant had to be recovered and the system completely evacuated. At our Winter Haven shop, the team performed the contamination recovery along with the A/C service with testing, which covered connecting the A/C equipment, verifying system pressures and refrigerant levels, charging the system with the proper refrigerant and oil capacity, and leak testing. UV dye was added to the system, and the vehicle owner was invited to return at no charge if the vehicle blows warm again so the team can search for the dye with special UV glasses and evaluate the leak.
