The ‘wet sock’ smell when the AC starts is biological: a damp coil, a slime pan, or mould on the blower. Perfume sprays hide it for an evening. Coastal towers get this more than inland villas because the coil stays wet.

Causes
- Dirty evaporator and blower
- Blocked drain sitting full of water
- Mould on duct lining after a leak
- Dead rodents in a return (less common, but we have seen it)
- Kitchen grease pulled into a nearby cassette
What you can safely check
- Change or wash filters.
- Run fan-only for a while after cooling to dry the coil if the unit has that option.
- Do not pour bleach into the indoor unit.
- Do not block the return with furniture.
When to get a technician
Smell returns within a day of cleaning filters, or you see black specks on the grille.
A standard split clean fixes many cases. If the smell is in every room of a ducted apartment, look at the FCU pan and the ducts, not only the bedroom split. Sanitization is an add-on after mechanical cleaning, not a substitute.

FAQs
Is it dangerous?
It is a moisture and hygiene problem. People with asthma notice it first. Fix the water, then the growth.
