AC Repair in Houston: what's different
Houston AC repair is as much about moisture as heat. Systems here remove gallons of water a day from May through October, so many no-cooling calls turn out to be a clogged condensate line or a tripped float switch in the attic rather than a failed compressor. Oversized units in older homes short-cycle and leave rooms muggy even when the thermostat is satisfied.
Many 1980s and 1990s homes in Spring Branch, Westchase and Clear Lake still run R-22 equipment, which makes refrigerant leaks expensive to fix. After tropical storms, outdoor units that sat in floodwater should be inspected before anyone switches them back on.
Houston climate
Summers are long, hot and muggy, with high dew points from May through October. Winters are short and mild, though occasional hard freezes stress heat pumps. Hurricanes and tropical storms bring flooding and power outages.

FAQ
AC Repair questions
Why does my Houston AC keep freezing up?+
Low airflow from dirty filters or coils and low refrigerant from leaks are the usual causes. In humid weather a frozen coil can also overflow the drain pan when it thaws, so turn the system off and call for a diagnosis.
Should I repair or replace my AC?+
Repair is usually the right call if the system is under 10 years old and the repair costs less than a third of a new system. Past 12–15 years in Las Vegas heat, or with an R-22 leak, replacement often makes more sense.
Why does my AC run but not cool?+
The most common causes are a dirty filter or coil, a failed outdoor fan motor or capacitor, or low refrigerant from a leak. A tech can tell which with a pressure and temperature test.
