Musty Smell When the AC Turns On
A stale or musty smell when the cooling system starts can come from buildup near returns, vents, or accessible ductwork. The estimate should confirm what is visible before cleaning.
What we check first
- Supply and return openings
- Accessible ductwork near the concern
- Visible dust, debris, or damp odor signs
- Cleaning options before work begins
Confirm the source before cleaning.
The technician reviews the visible system, explains what can be cleaned, and gives you the scope before the visit moves forward.
