How to Bathroom Exhaust Fan Check

Bathroom exhaust fans are your first line of defense against the moisture that hot showers introduce into your home. This inspection verifies that your fans are actually removing humid air to the outside—not just circulating it or dumping it into your attic where it causes serious damage. You'll test airflow, clean the fan and grille of dust buildup that reduces efficiency, verify the exterior vent is unobstructed, and check that the duct is properly connected. A properly functioning exhaust fan prevents the mold, peeling paint, and wood damage that excess bathroom moisture causes.
