01
Compressor
The pump. It squeezes refrigerant so it can carry heat out of the car.
When it fails: Warm air at idle, a clutch that will not engage, or a loud clatter when the AC turns on.

Car AC Refrigerant Leak Repair, Oakland Park FL.
Car AC refrigerant leak repair in Oakland Park. We find the leak with UV dye and an electronic detector, $200/hr, price before work. (954) 714-8099.
The quick answer
Front Line Auto finds where your car AC loses refrigerant with UV dye and an electronic leak detector, then gives you an itemized repair price before any work.
- Price
- Diagnostic labor $200/hr ($250/hr European). You approve an itemized total before any repair.
- What's included
- Pressure readings to confirm the system is low
- UV dye and lamp check of fittings, hoses, condenser and compressor seal
- Electronic leak detector pass, including the evaporator drain under the dash
- Written estimate for the leaking part, then the recharge after the repair
- How long it takes
- There is no fixed time. It is billed by the hour, and you get the time and total before work starts. A slow leak may need dye added and a return visit after a few days of driving so it shows under the UV lamp.

How your AC works
One loop, five parts. Find the one that failed.
Refrigerant leaves the compressor hot, gives its heat away at the front of the car, and comes back cold through the dash. Tap a part to see what it does and how it fails. Low on refrigerant? That is a leak somewhere in this loop, and we find it before we recharge.
02
Condenser
The radiator for your AC, in front of the engine radiator. It sheds the heat the compressor built up.
When it fails: Cold on the highway, warm in traffic. Road debris can bend fins or puncture it.
When the AC is not cold03
Receiver-drier
A filter canister that pulls moisture and debris out of the refrigerant.
When it fails: Cooling that fades over weeks. It is replaced whenever the system has been opened.
Recharge, done right04
Expansion valve
Drops the pressure right before the evaporator, so the refrigerant turns cold.
When it fails: Cold at first, then fading; frost on the valve; vents that are cold on one side.

Evaporator
The cold coil behind your dash. The blower pushes cabin air through it.
When it fails: A musty smell, weak airflow, or leak dye showing at the drain under the car.

More about this repair: what is involved and what the shop checks
What the repair involves
If your car AC cools right after a recharge and then turns warm again, refrigerant is escaping through a leak. Front Line Auto uses electronic halogen leak detectors, ultraviolet (UV) fluorescent dye, and nitrogen pressure testing to locate exact leak points across hoses, O-rings, service ports, condenser seams, and evaporator cores before quoting repairs.
Why timing matters on this repair
Service work is easier to approve when the vehicle has been inspected and the repair path is explained first. Front Line Auto ties common repairs back to the actual condition of the car.
What Front Line Auto checks
- Perform visual inspection with high-intensity ultraviolet (UV) light for fluorescent dye traces at all fittings and seals.
- Scan high-pressure lines, condenser, compressor shaft seal, and evaporator drain with electronic halogen sniffers.
- Check high- and low-side service port Schrader valves for micro-seepage under pressure.
- Conduct nitrogen pressure decay testing to confirm system integrity when leaks are microscopic or elusive.
- Inspect the under-dash evaporator condensate drain tube for oil or dye residue indicating internal core leakage.
- Provide an itemized estimate for seal, line, or component replacement with published labor rates ($200/hr non-European, $250/hr European).
Why repair the refrigerant leak instead of recharging again?
Because the refrigerant you pay for goes out the same hole. The EPA says topping off or recharging improves cooling but does not permanently fix a leak, and that repairing or replacing the leaking part gives longer-lasting results. A leak also lets the compressor's oil travel out with the refrigerant, and a compressor running low on oil is the expensive way this ends.
Common leak points are the Schrader valves in the service ports, O-rings at the line fittings, a condenser hit by road debris, the compressor shaft seal and, less often, the evaporator behind the dash. Finding which one it is turns a seasonal recharge into a single repair with a known price.

How does a shop find a car AC refrigerant leak?
Two ways, often together. UV dye is added to the system and shows up as a bright trace under a UV lamp where refrigerant escapes. An electronic detector sniffs for refrigerant at fittings, hoses and the evaporator drain. Before any part is opened, the remaining refrigerant has to be recovered: under Section 609 of the Clean Air Act, anyone paid to service car AC must be EPA-certified and use EPA-approved recovery equipment, and venting refrigerant is prohibited.
After the repair, the system is put under vacuum to check that it holds, then recharged to the factory weight. That vacuum hold is the proof the leak is gone, before you drive away.
When to call

Questions customers ask
How much does refrigerant leak repair cost?
Finding the leak is billed as diagnostic labor at $200 per hour ($250 per hour on European cars). The repair price depends on the part that leaks, and you get it itemized in writing before any work.
Can a leak sealer fix it?
Sealer products can clog the small passages in the system and the shop's recovery equipment. Finding and replacing the leaking part is the repair that lasts.
How do I know my car AC has a leak?
It cools after a recharge and then turns warm again within weeks or months, there is oily residue on AC lines or fittings, or the compressor clicks on and off quickly.
Do you work on cars only?
Yes. Front Line Auto is a car repair shop. It does not service home or building air conditioners.
