Most likely causes

  1. Mold/mildew on the evaporator — The evaporator stays damp in Florida humidity; growth on its fins is the classic source.
  2. Saturated cabin air filter — An old filter traps debris and moisture and re-circulates the smell.
  3. Clogged evaporator drain — When condensation can't drain, water pools and stagnates — sometimes wetting the carpet too.

What to do

Start with the cabin air filter — cheap and often overdue. If the smell persists, an evaporator cleaning service and clearing the drain line handles the source rather than masking it.

Common questions

Is the musty A/C smell harmful?

It can aggravate allergies and asthma; it's air you're breathing, so it's worth addressing.

Why does it smell worst at startup?

The blower pushes air over the damp evaporator where growth accumulates overnight.

Will a spray from the parts store fix it?

Surface sprays help mild cases; established growth on the evaporator usually needs a proper cleaning service.
