Your AC Is Not Built for 105 Degrees — But It Should Still Cope
Houston's design temperature is around 99 degrees, so on the hottest afternoons your system will run almost constantly and may only hold the house in the high 70s. That is normal. What is not normal is warm air from the vents, ice on the lines, water where it should not be, or a system that cycles on and off every few minutes.
The difference between a system that survives August and one that dies in it is usually maintenance: a clean coil, a clear drain line, a healthy capacitor, and the right refrigerant charge. Most of the failures on this page are preventable with a spring tune-up — and most of the rest are fixable the same day if you call early.
If the system is icing up, turn it off at the thermostat and let it thaw — running it frozen damages the compressor.
A tripped breaker can be reset once. If it trips again, leave it off and call us.
Water leaking from the indoor unit means the drain is blocked — turn the system off to limit ceiling damage.
Keep the outdoor unit clear of leaves, grass clippings, and stored items so it can breathe.
