AC Repair San Marcos & I-35 Corridor

Signs your AC needs repair

The system runs but the air from the vents isn't cold
The outdoor unit hums but the fan doesn't spin
Ice on the refrigerant lines or the indoor coil
Water around the indoor unit or a tripped float switch
Breakers tripping, or the system short-cycling on and off
New noises: grinding, squealing, banging or buzzing
Some rooms much warmer than others, or humidity that won't come down

What we work on

We service central air conditioners and the parts that keep them running, including:

Capacitors, contactors and motors
Condenser and evaporator coils
Refrigerant leaks and charge
Thermostats and controls
Condensate drains, pans and float switches
Blower and airflow problems

Why systems fail in Central Texas

Long stretches of 95°F-plus days mean an AC here can run for hours at a time from May through September. That load wears out capacitors and motors and exposes small refrigerant leaks. Cottonwood fluff, grass clippings and dust clog outdoor coils, and the humidity keeps condensate drains busy. A clogged drain is one of the most common reasons a system shuts itself off.

What to check before you call

Make sure the thermostat is set to Cool and below room temperature, and replace its batteries if it has them
Check the breakers for both the indoor and outdoor units
Replace a dirty air filter
Make sure the outdoor unit isn't blocked by plants or debris
If you see ice, turn the system off and let it thaw. Running a frozen system can damage the compressor.

Older systems and refrigerant

If your system uses R-22 (common in units installed before about 2010), new R-22 hasn't been produced in the U.S. since 2020, so recharging is expensive. In that case we'll talk through repair versus replacement so you can decide. See AC installation & replacement.

Frequently asked questions

Is it worth repairing an old AC?

It depends on the age of the system, the refrigerant it uses, the cost of the repair and how well it has been keeping up. A single failed part on an otherwise healthy system is usually worth fixing. Repeated major repairs, or an R-22 system with a leak, often point toward replacement.

Why is my AC running but not cooling?

Common causes include a dirty filter or coil, low refrigerant from a leak, a failed capacitor or fan motor outside, or a frozen indoor coil. A technician needs to test the system to know which.

Do you repair commercial AC units too?

Yes. We work on commercial systems, including rooftop units. See commercial HVAC.
