What to know about indoor air quality in La Porte
La Porte sits on Galveston Bay east of Houston, so salty, humid bay air is part of daily life. Salt can corrode the outdoor coil and electrical parts over time, and a gentle rinse of the outdoor unit a few times a year helps. After strong storms, have the system checked before running it if it was hit by water or debris.
- 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 La Porte 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.
