AC Not Cooling in San Antonio, TX

An AC not cooling in San Antonio, TX is the most common call we take all summer. The system runs. Air moves. The house still sits at 79 degrees at 6 pm. That pattern has a short list of causes, and our crew works through it in order instead of guessing.

First we check the temperature split. A healthy central air system drops return air about 15 to 20 degrees across the evaporator coil. If the split is 8 degrees, the problem is on the refrigerant side or the airflow side, and we go looking. A clogged filter or a matted evaporator coil chokes airflow. A dirty outdoor condenser coil can't shed heat. A slow leak leaves the system undercharged, which shows up as low suction pressure on our gauges and often as ice on the suction line. Our page on refrigerant leak repair covers how we trace those.

Sometimes the unit is simply too small for the house, or ductwork in a hot attic is leaking cold air into the insulation. We'll tell you straight if that is the case.

Call (866) 703-1217 and our crew will measure what your AC not cooling problem really is before we quote a repair.

Central AC Repair FAQs

Common questions about central AC repair

Questions we hear about AC Not Cooling in San Antonio, TX.

Talk to our crew
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.
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.
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.
What should I do before the technician arrives?
Check that the thermostat is set to COOL and below room temperature, check the breaker and the outdoor disconnect, and look at the filter. If there is ice, turn cooling off and run the fan. If there is a burning smell, shut the breaker off and leave it off.
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.
