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.

AC Only Blows Cold While the Car Is Moving

What the customer reported

The vehicle owner reported that the A/C isn't working properly: when the car is idle cold air doesn't blow, and when the car is moving cold air blows. The owner also said the A/C sometimes works when it's not hot, and the car needs to be in motion for the air to be cool.

What we found and did

The technician's A/C service found the system had 0.00 lbs of freon when it should have had 0.00 lbs. The technician evacuated and recharged the R134A system and added UV dye so any leak could be found later with special UV glasses. The invoice also lists removal and replacement of the air conditioning compressor, condenser, and front and rear expansion valves. The team invited the owner to return at no charge if the vehicle blows warm again so the leak could be evaluated.

Car AC Stops Blowing After 30 Minutes of Driving

What the customer reported

The vehicle owner reported the A/C was still not working even though the compressor was replaced last week, and it stops blowing after 30 min of driving.

What we found and did

The technician started with a Testing - Initial Assessment at no charge and noted that further testing may be needed for a complete answer. The work performed on the visit was a Remove Replace A/C Evaporator Temperature Sensor service at our Winter Haven shop.

FAQ

Heating And AC Repair in Winter Haven: questions answered

Answered by our licensed technicians serving Winter Haven.

Can you just add refrigerant and see if it holds?

We can, and sometimes that's the right call on a system that's only slightly low with no evidence of a leak. But if the system lost enough to stop cooling, it lost it somewhere, and refilling it without finding that spot means paying for the same refrigerant twice. We'd rather look first and tell you what it will take.

How do you find a leak you can't see?

Three ways, usually in this order. Refrigerant carries oil with it, so the first pass is looking for the oily film a leak leaves on fittings, hoses and seals. Then an electronic detector, which picks up traces at the joint itself. For slow leaks we add UV dye, run the system, and bring the car back under a black light so the leak has time to mark its own location.

Is the water dripping under my car normal?

If it's clear water under the passenger side after the AC has been running, that's condensation coming off the drain tube and it's exactly what should happen in this humidity. What isn't normal is that water showing up inside on the carpet, or a puddle that's colored, slick or sweet smelling. Bring those in.

Does the AC need servicing on a schedule?

We don't sell a recharge on a mileage interval, because a sealed system that's cooling properly doesn't need one. What is worth doing is checking vent temperature and the cabin filter during a regular inspection, so a slow loss gets caught while it's still cheap. If a system needs refrigerant every year to stay cold, the honest answer is that it's leaking every year.

Should I run the AC during the cooler months?

Yes, and it costs you nothing to do it. The compressor's seals stay lubricated by refrigerant oil circulating through the system, and a system that sits unused all winter is more likely to weep at those seals. Running the defroster does it automatically on most vehicles, since the AC compressor runs in defrost mode to dry the air.
