What to know about indoor air quality in Galveston

On Galveston Island, salt air is hard on outdoor AC units, and corroded coils and electrical parts are common. Many homes are raised for flooding, so outdoor units often sit on platforms, and some older homes have limited space for ductwork. After a storm, have the system checked before turning it back on.

  • 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 Galveston 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.
