Read the full jobIn Central Florida a dead AC isn't really a comfort problem. It's whether the car is usable in August, and we treat it that way. Cold air comes back faster when the diagnosis is right the first time, so here's how that actually works.
Air conditioning isn't a tank of cold that gets used up. It's a sealed loop, and the same refrigerant circles it over and over. So when a system that used to blow cold doesn't anymore, something specific changed: refrigerant escaped through a leak, a part stopped moving it, or the air side stopped delivering it to the vents. Those are three different repairs with three different bills.
Diagnosis starts with pressure. We put gauges on the high and low side and read what the system does while it's running. Low on both sides points one direction. High head pressure with weak cooling points another. Add vent temperature measured against the outside air and humidity, plus how the blower and blend doors behave, and the picture narrows quickly.
If the charge is low, the next question is where it went, because refrigerant doesn't get consumed. We look for the oily residue a leak leaves behind, run an electronic detector along the fittings, hoses, condenser and service ports, and add UV dye when a slow leak needs time to show itself. Those photos come to your phone with the digital inspection, so you see the stain or the dye ring for yourself.
That's also why a recharge on its own is a temporary answer on a system that leaks. Putting refrigerant into a system that's losing it buys a few weeks of cold air and puts the same problem back on your calendar. Charging is the last step of a repair, not the repair.
Heat that never warms up, a musty smell, a noise when the compressor engages: same bay, same approach. We find it, show you the photos, and give you a number before anything comes apart. The work carries a 36 month / 36,000 mile nationwide warranty.

Our experts diagnose and resolve any issue.
At speed there's plenty of air moving through the condenser, and at idle there isn't unless the cooling fan is doing its job. A charge that's slightly low behaves the same way, so the gauges tell us which one you have.
That pattern is a leak, and the size of the leak sets how long the cold lasted. Refrigerant doesn't wear out, so anything that left the system left through a hole we can find.
The cold parts of the system pull moisture out of the air, and that moisture has to drain away instead of sitting in the case. A slow or blocked drain and a loaded cabin filter are the usual reasons it doesn't.
The compressor clutch engaging and releasing over and over is often a low charge tripping the pressure switch, not a failed part. A squeal that lasts is more likely a belt or a bearing, and those sound different on a stethoscope.
Heat comes off engine coolant, so low coolant, an air pocket or a thermostat stuck open will all produce lukewarm vents. A blend door actuator that isn't moving does the same thing with a perfectly healthy engine.
When the air is cold but there isn't much of it, the problem is usually on the air side: a clogged cabin filter, a tired blower motor, or a failed blower resistor. It's the cheapest thing on this list to check, so we check it first.
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 :)

The AC on our 2020 Cadillac XT4 quit working, and in Florida, that's not acceptable. Called Johnny's Automotive and was able to bring it in that same day. Waited for about half an hour while they checked it out. Come to find out the AC Compressor clutch fell apart and we needed a new compressor. They ordered the part and gave me a ride home. The next day, after the repairs were done, they picked me up and drove me back to their shop. After paying the bill, I got in my vehicle and there were 4 long stem red roses laying on the dash. Never had that happen, ever. If you need your vehicle repaired, I highly recommend Johnny's to help you out!! Very knowledgeable and helpful!!! If I could give them 10 stars, I would. Go see them, you won't be disappointed!! Thanks Johnny's, you people did a awesome job!!

Everyone was very kind and courteous. They have a nice waiting room. They had to put in a new compressor and condenser and fix the mixing door. The air-conditioning works great! The price is what you would expect, it’s a top-notch shop and I will go again.

Your car's AC doesn't make cold, it moves heat out of the cabin. That one idea explains why Florida is so hard on these systems, and which habits actually help.
Read articleCommon questions about our heating and ac repair.
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.
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.
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.
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.
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.
