What to know about indoor air quality 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.
- High indoor humidity feels sticky and encourages mold. The EPA suggests keeping indoor humidity below 60%, ideally 30–50%.
- A higher-rated air filter (MERV) catches more pollen and dust, but check that your system can handle it.
- After flooding or roof leaks, have ducts and the air handler inspected for mold.
- Ask whether a whole-home dehumidifier makes sense for your house.
Indoor air quality questions from Houston homeowners
Do I need duct cleaning?
Not on a set schedule. It can help after renovation dust, pests or water damage. Ask the company what they found before agreeing to it.
Why is my house humid even with the AC on?
An oversized AC, a dirty coil or airflow problems can leave humidity high. A technician can check.
