What to know about heating 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.
- Test your heat before the first cold front, not during it.
- Many Houston homes use heat pumps. During a freeze, "aux" or "emergency heat" coming on is normal.
- Homes with a gas furnace should have working carbon monoxide detectors.
- A burning-dust smell the first time the heat runs is common; a strong or lasting smell is a reason to call a pro.
Heating repair questions from Katy homeowners
Why does my heat pump blow lukewarm air?
Heat pumps deliver gentler, steadier heat than a furnace. If rooms aren't reaching the set temperature, have a technician check it.
When should I get my heating checked?
Fall, before the first cold front, is the easiest time to get an appointment.
