Why is my AC blowing a weird smell?
Clogged air filters become moisture-laden and breed mold. Dirty filters are unable to capture pollutants, which flow into the system. If the drip pan is blocked, water may back up, causing a musty smell. If coils become coated with dust, they may give off a bad smell as they expel heat.
Why does my car AC smell like feet?
The air from your blower motor forces air across this surface and out through the vents in your dash, floor, and defroster. This results in the “dirty sock” like odor you smell when you first start your car and turn on your air conditioner.
Why does my AC smell at first?
Dust, hair, and moisture on the AC filter encourage mildew growth, which can cause a musty odor when the air conditioner runs. This is a likely reason why the air conditioner smells when first turned on if you don’t use forced-air heating in winter. To help prevent this odor, clean or replace the filter in the spring.
