What to Do When Your AC Stops Working in the Houston Heat

When the temperature outside hits 100°F (38°C), a broken air conditioner goes from being an inconvenience to a dangerous health hazard within hours. Here is what you must do if your AC fails.

Step 1: Check the Thermostat and Breaker

Sometimes, the fix is incredibly simple. Ensure your thermostat has fresh batteries and is set to "Cool." Next, check your electrical panel. If the breaker is tripped, reset it once. If it trips again, do not reset it—you have a dangerous short circuit. Call a [Houston AC repair] technician.

Step 2: Change Your Air Filter

A completely clogged air filter restricts airflow so severely that it can freeze the evaporator coil or cause the compressor to overheat and shut down.

Step 3: Keep the Heat Out

Close all blinds, curtains, and shades, especially on south and west-facing windows. Avoid using the oven or stove, and keep doors closed to trap the remaining cool air inside.

Step 4: Hydrate and Circulate

Turn on ceiling fans (ensure they are spinning counterclockwise to push air down) and drink plenty of water. If you have elderly family members or infants, consider relocating them to a cooling center or a friend's house.

When to Call for Emergency Repair

If checking the breaker and filter doesn't work, you need professional help. Waiting until Monday will only make your house hotter and the wait time longer. Call Texaserv for rapid dispatch of a licensed HVAC technician.
