Notice when it happens
After rain? When the AC starts? In one room? Those details can narrow the search.
Musty smells
Why does my house smell musty?
A persistent musty or damp smell is worth investigating. The odor may be related to excess moisture, wet materials, HVAC components or microbial growth, but smell alone cannot tell you exactly what is happening.

What to know
Treat the smell as a clue, not the problem itself.
Air fresheners can hide an odor without changing its source. A better approach is to notice when the smell appears, look for moisture or water damage, check indoor humidity and determine whether the HVAC system is part of the pattern.
Check moisture before buying odor products
Look for condensation, water stains, damp materials and elevated humidity.
