What to know about commercial HVAC 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.
- Ask about experience with your type of equipment, such as rooftop units or chillers.
- A preventive maintenance contract can reduce surprise breakdowns during summer.
- Ask about after-hours service so repairs don't interrupt business.
- Request proof of insurance and the company's Texas ACR license number.
