Why Is My AC Not Cooling Properly?

What the customer reported

The vehicle owner reported that the air conditioning in their 2015 Honda Fit was blowing strong but not cooling, with the AC compressor clutch engaging and immediately shutting off.

What we found and did

The technician found that the AC system had 0.00 lbs of refrigerant, indicating a lack of refrigerant as the cause of the cooling issue. The team evacuated the system of contaminants, verified system pressures and refrigerant levels, and recharged the AC system with the proper refrigerant and oil capacity. A UV dye was added to the system to help identify any potential leaks in the future.

Result

After recharging the system, the AC functioned properly, providing cool air as expected.

Pro Tip

If your AC stops cooling effectively, it might be due to low refrigerant levels. Recharging the system can restore cooling, but adding UV dye helps detect leaks if the issue recurs.

Why Is My AC Blowing Warm Air After Cooling?

What the customer reported

The vehicle's air conditioning system was not maintaining a consistent temperature. Initially, it would blow cold air but then switch to warm air, accompanied by a clicking sound from an actuator.

What we found and did

The technician found that the evaporator temperature sensor was giving erratic voltage readings, which indicated it needed replacement. The team performed a diagnostic test on the ECM/PCM and checked the voltage at the AC compressor. They identified the faulty evaporator temperature sensor and replaced it to resolve the issue.

Result

After the repair, the air conditioning system maintained a consistent cold temperature, eliminating the warm air problem.

Pro Tip

If your AC starts blowing warm air after initially cooling, it might be due to a faulty temperature sensor. Addressing this early can prevent further discomfort and potential system damage.

Why Won't My Turn Signals Stay On?

What the customer reported

The vehicle's passenger window was not operating, the AC airflow did not switch between vent and defrost, and the turn signals would blink and then stay on.

What we found and did

The technician found issues with the power window motor and regulator assembly, the hazard warning turn signal flasher, and the AC system being completely depleted of refrigerant. The team replaced the power window motor and regulator assembly to restore window functionality. They also replaced the hazard warning turn signal flasher to ensure proper operation of the turn signals. For the AC system, they evacuated and recharged the system with the correct amount of R134A refrigerant, adding UV dye to detect any future leaks.

Result

After the repairs, the passenger window functioned correctly, the turn signals operated normally, and the AC system blew cold air.

Pro Tip

If your turn signals blink but don't stay on, the flasher unit may be failing. Replacing it promptly ensures your signals work correctly, enhancing safety on the road.

Why Is My Car's AC Blowing Hot Air?

What the customer reported

The vehicle owner reported an unusual engine noise and was concerned about the air conditioning system not functioning properly.

What we found and did

The technician found that the air conditioning system had zero pounds of refrigerant, indicating a potential leak. The team performed a supercharger oil service, replaced the drive belt tensioner, and addressed the AC issue by evacuating and recharging the system with the proper amount of refrigerant. They also added UV dye to help detect any future leaks.

Result

The air conditioning system was restored to proper functionality, providing cool air once again.

Pro Tip

If your AC starts blowing warm air, it might be due to a refrigerant leak. Adding UV dye during a recharge can help pinpoint leaks early, saving you from more costly repairs later.

Reviews

What Sebring customers say about our heating and ac repair work

Having issues with my A/C and came here for the diagnostic for it. Waiting lobby is the best I've ever seen in an auto shop. Pleasant and friendly staff with extraordinary knowledge that is easy to understand without a chemistry set. Did not have the work done which was a personal decision not based on them at all. Also I received 2 roses at the end which was a first and brightened my day!! Ill be coming back for sure with my other vehicles soon.

You honestly pay for the awesome quality of service they provide (mechanical & customer service)!!! I came in for an AC issue and after a week, no complaints or problems thus far! I also appreciated the through inspection they did on my little Chevy; I’m truly thankful to them for helping me get my car back on track :)

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.

FAQ

Heating And AC Repair in Sebring: questions answered

Answered by our licensed technicians serving Sebring.

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.
