Our EPA Section 608–certified technicians perform leak detection, verify the refrigerant circuit, and repair or recommend replacement based on what they actually find — for both modern R-410A systems and older R-22 units.
Signs of a refrigerant leak
- Warm air even though the system runs constantly
- Ice on the refrigerant lines or evaporator coil
- A hissing or bubbling sound near the lines
- Rising energy bills with weaker cooling
- The AC that 'needs Freon' every summer
- Longer runtimes without reaching the setpoint
What affects your price
Figures below are published local benchmarks and non-binding estimates — never a quote. You'll get every charge in writing first.
- Published refrigerant recharge benchmark $150–$425 (R-22 costs more)
- Leak location and repair difficulty
- Coil or component replacement if the leak is in the coil
- System age and refrigerant type (R-410A vs. R-22)
What's included with refrigerant leak repair in Covington
Every refrigerant leak repair job is scoped and documented up front — here's what you get when we roll up to your Northshore home or business.
- Electronic sniffer and UV dye sweep of coils, joints, service valves, and line sets to pinpoint the actual leak
- Nitrogen pressure test held and timed so we confirm the leak is sealed, not just quieted
- Proper braze or flare/component replacement at the failure point instead of a top-off that leaks again
- System evacuated to deep vacuum and weighed-in charge to spec for your exact refrigerant, R-410A or older R-22
- EPA 608 certified recovery of removed refrigerant with recovery documented for your records
- Superheat and subcooling verified after recharge so the fix reads correct at the gauges
- Written leak location, repair method, and charge weight left with you
Find the leak, then fix it right
We use electronic detection, and where needed dye or nitrogen pressure testing, to locate the leak — a corroded coil, a worn line-set connection, a failed valve, or a cracked component. Then we present your options: repair the specific failure, or, if the coil or compressor is failing, weigh a replacement.
Because handling refrigerant requires EPA Section 608 certification, this isn't DIY territory. We document refrigerant performance and separate recharge, leak repair, and any follow-up costs so you can see exactly what you're paying for.
R-22 systems and your options
Older R-22 units are increasingly expensive to service because that refrigerant has been phased down and prices have climbed. If you have an aging R-22 system with a significant leak, we'll give you honest repair-versus-replace math rather than pouring costly refrigerant into a system near the end of its life.
Our refrigerant leak repair process
Test first, document everything, and get your sign-off before the work happens — no guesswork, no surprises.
- 1
Confirm the loss
We verify low charge with gauges and check performance so we're chasing a real leak, not a fouled coil or a bad capacitor.
- 2
Locate the leak
Sniffer, bubble solution, and UV dye trace the exact fitting or coil section that's losing refrigerant across the line set.
- 3
Recover and repair
We recover the remaining charge to EPA 608 standards, then braze or replace the failed joint or component properly.
- 4
Pressure test and evacuate
Nitrogen holds pressure to prove the seal, then we pull a deep vacuum to remove moisture and non-condensables.
- 5
Recharge and verify
We weigh in the correct charge for R-410A or R-22 and confirm superheat and subcooling before we call it done.

Refrigerant Leak Repair FAQs
Usually not on its own. A low charge means refrigerant escaped somewhere, so a recharge without finding and repairing the leak is a temporary fix. We locate the leak, document refrigerant performance, and separate recharge, leak repair, and follow-up costs so the problem is actually solved.
