Refrigerant Leak Repair in San Antonio, TX

Refrigerant leak repair in San Antonio, TX starts with a simple fact: a central AC system is sealed. It does not use up refrigerant. If the charge is low, it leaked out somewhere, and adding more without finding the leak means paying for the same refrigerant twice.

Our crew traces leaks with an electronic detector first, then bubble solution to pinpoint the spot. Common leak points on central air systems are the Schrader valve cores at the service ports, flare nuts on the line set, the U-bends of an evaporator coil where formicary corrosion eats pinholes in the copper, and the brazed joints at the condenser. Slow leaks sometimes need UV dye and a return visit.

Once the leak is fixed we pull a vacuum down to 500 microns, confirm it holds, and weigh in the charge to the nameplate spec. That process matters more than the refrigerant itself.

Older systems running R-22 are a separate conversation. R-22 has not been produced or imported in the US since 2020, so what is left is reclaimed stock and it is expensive. We'll give you the cost to repair next to the cost to replace so you can decide. Call (866) 703-1217.

Central AC Repair FAQs

Common questions about central AC repair

Questions we hear about Refrigerant Leak Repair in San Antonio, TX.

Talk to our crew
Is it worth repairing an older R-22 system?
Sometimes. R-22 has not been produced or imported in the US since 2020, so any recharge uses reclaimed refrigerant at a high price. A small electrical repair on an R-22 unit can still make sense. A major leak or a failed compressor on one usually does not. We'll give you both numbers.
Why is there ice on my AC lines?
Ice forms when the indoor coil gets too cold, usually from low airflow (dirty filter, dirty coil, weak blower) or low refrigerant charge. Turn cooling off and run the fan to thaw it, then call us. Running a frozen system can damage the compressor.
Can you just add refrigerant to my AC?
We can, but it rarely makes sense on its own. A central AC system is sealed, so low refrigerant means a leak. Topping it off without fixing the leak means the charge leaks out again. We find the leak, repair it and weigh in the correct charge.
How long does a central AC system usually last?
Many central air systems run 12 to 15 years with regular maintenance. Units near the coast, where salt air corrodes coils, and units in very long cooling seasons often wear out sooner. Age alone is not a reason to replace, but it factors into repair decisions.
Why is water leaking from my indoor unit?
Most of the time it is a clogged condensate drain line, a cracked or rusted drain pan, or a frozen coil that is melting. Turn the system off to limit water damage and call us. We clear the line, check the pan and test the safety float switch.
