What to know about HVAC maintenance in Houston
Houston's cooling season runs most of the year, and in this humidity your AC is pulling moisture out of the air as well as heat, so a struggling system often shows up first as a sticky, damp-feeling house. Many Houston homes have the air handler in the attic, where summer heat is hard on parts and a clogged drain line can leak into the ceiling below. Companies get busiest in the first big heat wave of the year and after storms, so call early in the day.
- Book an AC tune-up in spring, before summer demand peaks, and a heating check in fall.
- A tune-up usually covers cleaning coils, clearing the condensate drain line, checking electrical parts and refrigerant levels.
- Houston humidity makes clogged drain lines a common cause of leaks. Ask for the drain to be flushed.
- Change filters every one to three months, more often with pets.
- Ask what a maintenance plan includes and whether it gives priority service.
