Why Does My AC Smell Musty?

If you have ever turned on your AC to find a weird smell coming from the vents, then you likely understand what it means to panic. No one wants a weird smell in their home, especially when that smell is a musty, damp smell.

There is a reason why people panic when they smell that musty smell, this is due to the fact that musty smells are often related to mold and mildew. Mold build-up can cause health problems within your home, increasing allergies, making it harder to breathe, and causing prolonged illness.

Why Does My AC Smell Musty?

There are many reasons why you may be smelling that musty smell coming from your home’s AC system.

  • Stagnant Water – If you have stagnant water sitting in your AC’s drip pan this could lead to mildew build up within your system. When water pools it often means there is a blockage somewhere in the condensate drain pipe.
  • Oversized AC Systems – If you are smelling a musty smell in your home, it could be due to your AC system being too big for the amount of square footage it is cooling. When the AC system is too big air rushes through the system without dehumidifying, this leads to too much moisture in your pipes and can cause mold and mildew to build up.
  • Dirty Ducts and Vents – If your home often feels humid or you live in a humid climate, these high humidity levels can cause mold and mildew build-up throughout your home, including in your AC ducts and vents. Mold can spread quickly and you will be able to smell that musty smell whenever your AC turns on.
