Accurate leak detection and permanent repair across Southeast Florida, with EPA-compliant recharge and performance verification. An air conditioner is a sealed system, so if it is low on refrigerant, it is leaking. We find it before we fill it.
Leak Detection Before Recharge • EPA Certified Technicians • Residential & Commercial Systems
The Short Answer
Comfort Zone provides expert refrigerant leak detection and repair throughout Southeast Florida, including Palm Beach, Martin, and St. Lucie Counties, as a licensed Florida HVAC contractor (License #CAC1823915) with EPA-certified refrigerant specialists. Our technicians locate the exact source of the leak, complete the necessary repairs, and then recharge the system to the manufacturer's specifications.
If your air conditioner is running but not cooling effectively, a refrigerant leak may be to blame. Refrigerant circulates through the system to absorb and release heat, and when levels drop, cooling capacity falls while strain on the compressor increases.
Thorough leak detection and repair restore cooling performance, stabilize refrigerant pressure, and help protect your compressor from long-term damage during South Florida's long, demanding cooling season.
Symptoms To Watch For
Refrigerant leaks often develop gradually, causing cooling performance to decline over time. Because Southeast Florida systems run nearly year-round, even small leaks can quickly affect system operation.
A common misconception is that air conditioners “use up” refrigerant the way a car uses oil, and need topping up periodically. They do not. A sealed system that is low on refrigerant is leaking, full stop.
If a contractor has recharged your system more than once without ever locating a leak, you have been paying for refrigerant that went straight into the atmosphere, and the underlying fault is still there getting worse.
Get It Diagnosed ProperlyDetection Before Recharge
Adding refrigerant without locating the leak source is not a permanent repair. Our structured detection process identifies where the system is losing charge before any refrigerant is added, so the repair addresses the cause rather than the symptom.
Refrigerant pressure testing establishes whether the system is genuinely undercharged and how severely, which frames everything that follows.
Inspection of exposed copper line sets, where corrosion, vibration fatigue, and physical damage most often show up first.
Evaporator and condenser coil inspection. Coil leaks are common in coastal Florida and are the most consequential to find, since they change the repair calculus entirely.
Electronic leak detection when the source is not visually apparent, pinpointing small or concealed leaks that pressure testing alone cannot locate.
Service valve and connection evaluation, since fittings and valve cores are a frequent and inexpensively fixed leak point.
Matched To The Fault
The type of repair depends on the location and severity of the leak, as well as the age and condition of the system. Our technicians evaluate system age, refrigerant type, and mechanical condition before recommending repair or component replacement.
Minor leaks in accessible copper lines can often be repaired quickly and inexpensively.
When corrosion or multiple leak points are present, replacing the entire line set is often the most reliable long-term solution.
Regulated Work
After the leak is repaired, the system must be properly evacuated and recharged to restore performance. EPA regulations require certified handling of refrigerants and prohibit intentional refrigerant venting. Our EPA-certified technicians follow compliant recovery, repair, and recharge procedures before returning the system to operation.
Removes moisture and contaminants from the circuit. Moisture left in a system forms acid and destroys the compressor from the inside, so this step is not optional.
Refrigerant charged to manufacturer specification by weight, not guessed by gauge pressure alone.
Verification that the charge is genuinely correct under real operating conditions, which is the only way to confirm it.
Confirmation that the compressor is drawing normal current after the repair, catching damage the leak may already have caused.
Airflow performance testing, because a correct charge on a restricted system still will not cool properly.
Proper calibration restores cooling capacity and humidity control during Southeast Florida's peak cooling demand.
Why Timing Matters
Operating a system with low refrigerant increases compressor temperature and mechanical stress. Continued operation while undercharged can eventually lead to compressor failure, one of the most expensive HVAC repairs there is. Addressing leaks early prevents larger mechanical failures and protects the overall system investment.
Salt-laden coastal air attacks copper tubing, coil surfaces, and brazed joints from the outside in. Vibration across years of near-continuous runtime fatigues joints and connections. Storm and landscaping damage accounts for much of the rest.
A leak repair is a modest job. A compressor replacement is one of the largest single repairs on the system, and on an older unit it frequently pushes the decision to full replacement instead. The gap between those two numbers is the argument for acting early.
Refrigerant Questions, Answered
No. Simply adding refrigerant is a temporary fix. Air conditioning systems are sealed, which means refrigerant loss always indicates a leak somewhere in the system.
The leak must be properly located and repaired to prevent ongoing issues and system damage, and EPA regulations prohibit knowingly topping off a leaking system as a substitute for repair.
Yes. We provide refrigerant leak detection and repair for both residential and commercial HVAC systems across Southeast Florida, including rooftop units and large-tonnage commercial equipment.
Yes. Low refrigerant levels cause the compressor to overheat and fail, leading to costly repairs or system replacement if not addressed promptly.
Refrigerant also carries oil through the circuit, so an undercharged system is a poorly lubricated one. That is why running low on refrigerant is far more damaging than it appears from the outside.
Costs depend on leak location, system type, and repair complexity. An accessible copper line repair sits at the low end, while evaporator coil replacement sits at the high end. We provide upfront pricing after a full diagnostic evaluation rather than quoting before the leak has been located.
Most repairs can be completed within a few hours, though complex leaks may require additional time or follow-up service. Coil replacement and full line-set replacement are longer jobs.
Corrosion is the leading cause in this region. Salt-laden coastal air attacks copper tubing, coil surfaces, and brazed joints from the outside in, and formic acid corrosion can pit evaporator coils from within.
Vibration over years of near-continuous runtime also fatigues joints and connections, and physical damage during landscaping or storms accounts for the rest.
It depends on the system's age. R-410A remains widely available. R-22 has been phased out of production and is increasingly expensive and difficult to source, so a significant leak on an R-22 system often costs more to recharge than the repair is worth.
In those cases system replacement is usually the better economic decision, and we present both options with real numbers.
Modern refrigerants used in residential systems are non-toxic and non-flammable under normal conditions, and leaks in a home are typically too small and too dispersed to pose a health hazard. The real risk is mechanical and financial: compressor damage from running undercharged.
That said, refrigerant should never be vented intentionally, and EPA regulations require certified handling and recovery.

Serving Palm Beach, Martin & St. Lucie Counties
Air conditioning systems in Southeast Florida operate through long cooling seasons, high humidity, and continuous compressor demand, which makes accurate leak detection and repair essential. Our technicians understand the region's building conditions, coastal climate stresses, and extended system runtime.
If your system has been recharged more than once without anyone locating a leak, the fault is still there and the compressor has been running undercharged the whole time. Get it found and repaired properly, with EPA-compliant recovery and charge verified to manufacturer specification.
