Frozen AC Coil Repair in San Antonio, TX

Frozen AC coil repair in San Antonio, TX begins with turning the cooling off. If you see ice on the copper line outside or frost on the indoor coil, running the AC longer only builds more ice and can send liquid refrigerant back to the compressor. Set the thermostat to OFF and the fan to ON to start the thaw.

A coil freezes when it gets too cold, and that happens for two main reasons. Low airflow is the first: a clogged filter, closed supply registers, a dirty evaporator coil or a weak blower motor lets the coil temperature drop below 32 degrees. Low refrigerant charge is the second, because a system that is short on refrigerant runs lower suction pressure and a colder coil.

Our crew checks both. We measure static pressure across the air handler, inspect the evaporator face for matted dust and pet hair, and put gauges on the system to read suction pressure and superheat. When the coil is dirty, we clean it with a non acid coil cleaner. When the charge is low, we go hunting for the (/services/refrigerant-leak-repair).

Melting ice also floods the drain pan, so we check the drain line too. Call (866) 703-1217.

Central AC Repair FAQs

Common questions about central AC repair

Questions we hear about Frozen AC Coil Repair in San Antonio, TX.

Talk to our crew
How often should I get an AC tune up?
Once a year, in spring, before the first long stretch of hot weather. In long cooling season states, some homeowners book a second check in late summer. A yearly AC tune up catches weak capacitors, pitted contactors and clogged drain lines while they are still cheap fixes.
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.
Why does my AC keep tripping the breaker?
Common causes are a compressor struggling to start because of a weak capacitor, a shorted fan motor, a compressor with a winding shorted to ground, or loose and overheated wiring. Resetting the breaker over and over can make it worse. Leave it off and call us.
Do you work on heat pumps and furnaces too?
Our focus is central air conditioning: split systems and packaged units, the outdoor condenser and the indoor coil and air handler. Call (866) 703-1217 and tell us what you have, and we'll let you know if it is a job for our crew.
