Why Does My AC Stop Blowing After 30 Minutes?

The Problem

The vehicle owner reported that the air conditioning system stopped blowing air after 30 minutes of driving, even though the compressor had been replaced last week.

What We Found

The technician performed an initial assessment and determined that further testing was needed to identify the issue.

The Fix

The team removed and replaced the A/C evaporator temperature sensor, which was likely causing the system to stop blowing air after a period of operation.

The Result

After replacing the sensor, the air conditioning system functioned normally, providing consistent airflow during extended drives.

Pro Tip

If your A/C stops blowing air after running for a while, it might be a faulty temperature sensor. Replacing it early can prevent discomfort and avoid more costly repairs.

What Winter Haven customers say about our heating and ac repair work

I needed a aux battery for my vehicle and Johnny's was able to get me in right away. I had been to the building when it was Ron's, boy has it changed. The place is immaculate. There is seating in the ac for waiting ,as well as a drink and munchies if you desire.The installation of my second battery didn't seen to take long at all,which means they know what they are doing as they are a pain in the butt to replace. The price was reasonable too. When I left there on my dashboard was a carnation. What a nice touch.I think they are going to be my go to.

Professionalism from the start, great communication, and quick delivery time. I took my vehicle to Johnny’s Automotive for what I thought was an AC problem, but they quickly found it was actually an overheating issue and an oil leak. Before coming here, I was scammed by Agua Wash and Lube, who falsely claimed my AC was recharged and had a leak. Just two hours later, the same issue came back. Johnny’s team found the freon was low and diagnosed the real problem with honesty and care. This is a credible, veteran-friendly shop that treats locals and visitors with integrity. Highly recommend!

Ron is an excellent, honest, knowledgeable mechanic who deserves ten-plus (10) stars. My mentor and close friend, Ms. Treasa, referred him to me, and he repaired my car's A/C, a tune-up, and the 57-point inspection; the car is excellent, and the A/C is working outstandingly. If you need a great and honest mechanic, do not look any further; you will not be disappointed. Ron, thank you so much, and may God continue showering you with abundant blessings from above. Warm regards, Bea Johnson.

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.
