What to know about AC repair in Katy
Katy has grown fast along I-10, and many homes in its master-planned communities are newer, often with the air handler in the attic. With the high summer temperatures out west of Houston, those attic units work hard, and a clogged condensate line is a common summer call. If your home is still under a builder or manufacturer warranty, check it before you book a repair.
- Check the easy things first: thermostat set to Cool, fresh batteries, and the breaker for the outdoor unit.
- A clogged air filter can stop cooling. Replace it if it looks gray or dusty.
- If you see ice on the indoor coil or the copper line outside, turn the system off and let it thaw before the tech arrives.
- Ask for the company's Texas ACR license number and a written estimate before work starts.
- Refrigerant work must be done by an EPA 608 certified technician.
AC repair questions from Katy homeowners
Should I repair or replace my AC?
It depends on the age of the system, the cost of the repair, and how often it has broken down. Ask the technician for both options in writing so you can compare.
How fast can someone come out?
It varies by company and season. Call two or three companies from the list and ask about their next available time.
How does AirScouter choose these companies?
