Car A/C Repair in Denton, TX · Since 1995
If your air conditioning went from cold to warm, the refrigerant didn't wear out — it leaked out. We find where it's escaping, fix the actual part, and recharge the system to factory spec so the cold lasts. Written estimate before any work.
The honest truth about low A/C
A car's air conditioning is a sealed loop. The same refrigerant circulates over and over — it never burns off, evaporates, or gets consumed the way gas or oil does. So when a system is low on refrigerant, there is only one explanation: it escaped through a leak somewhere. That's why a plain recharge without finding the leak is a countdown — you're paying to refill a system that will empty itself again, sometimes in weeks. We'd rather find the leak first.
Where car A/C leaks hide
Refrigerant escapes wherever the system is joined, sealed, or exposed. Some spots are easy to reach; others take hours of labor to get to. Here's the range, roughly from most common and accessible to least.
If the leak turns out to be the compressor shaft seal, that's its own repair — see our A/C compressor replacement page.
How we actually find the leak
A guess isn't a diagnosis. We use real leak-detection tools — often more than one — to confirm the exact source before we quote a repair.
We add a fluorescent dye to the system, run it, then scan every joint and component with an ultraviolet light. The dye glows bright at the exact spot it's escaping — good for slow leaks that only show over time.
Pinpoints visible, external leaks at seals, hoses, and the condenser.
A hand-held sniffer sweeps along the lines and fittings and alarms when it senses refrigerant in the air. It catches small leaks in tight spots a dye scan can't easily see.
Finds leaks hidden behind or under other parts, by detection instead of by eye.
We charge the empty system with inert nitrogen and watch the pressure, or pull it into a deep vacuum and watch that it holds. A pressure drop proves a leak exists and, with the other methods, helps us locate a stubborn one.
Confirms whether the system holds at all — used for sealed or intermittent leaks.
Which method we reach for depends on how fast the system is losing charge and where the symptoms point.
Two very different answers to a leak
The parts-store shelf sells a shortcut. Here's the honest difference between masking a leak and repairing it.

The right repair
We do not install stop-leak. If a previous can has already been run through your system, tell us — it changes how we service it.

Every A/C leak repair follows the same disciplined order so the fix holds.
The recharge step itself is covered in depth on our A/C recharge page.
Where your repair goes next
Once we know where the refrigerant is escaping, here's where the job may lead from here.
A leaking compressor is its own job — replacement, plus flushing the system it shares oil with.
A/C Compressor ReplacementOnce the leak is repaired, the system is evacuated and recharged by weight. See exactly how that's done.

A/C leak questions
It depends entirely on where the leak is. A dried-out O-ring or Schrader valve is inexpensive; a hose or condenser is more; an evaporator buried in the dash is labor-heavy because of everything that has to come apart to reach it. We won't quote a number over the phone without finding the leak first — you'll get an honest, written estimate before any work begins.
Parts stores mainly sell you refrigerant and stop-leak in a can — they're set up to sell products, not to diagnose. A real leak find takes UV dye and a black light or an electronic detector and someone to trace it. That's the part we do.
O-rings and seals at the system's connections are the most common — the rubber dries out and shrinks with age. The condenser up front is a close second because road debris and corrosion take their toll where it sits behind the grille.
Yes. A leak isn't a mystery — it's a failed part, and failed parts get replaced. We find the source, replace the seal, hose, condenser, or component that's leaking, then evacuate and recharge to spec so the cold holds.
You can drive the car — a refrigerant leak won't strand you. But you'll lose your cold air, and running a low or empty system can starve the compressor of the oil that circulates with the refrigerant, which risks turning a small leak into a big repair. It's better to have it looked at sooner.
We don't recommend it. Sealant in a can is meant to gum up small leaks from the inside, but it can just as easily clog the condenser and valves, foul the equipment used to service the system, and in the worst case contribute to a compressor failure. It also hides the real problem instead of fixing it.
