Running your air conditioning in summer helps keep your Indianapolis home from getting too hot. However, you might not enjoy having it on if it gives off a musty smell. Knowing more about why you might have a musty AC can help you figure out what to do about it and how to prevent it.

Causes of Musty Odors

AC systems can develop this kind of smell for different reasons. Dirty coils or a dirty air filter can make your AC smell this way. A full drip pan, mold or mildew in your ducts, or an AC system that’s too small for your home can all lead to a musty smell. In general, a moisture problem allows mold or mildew to grow, resulting in these odors.

When mold or mildew grow anywhere inside your AC unit or in your ductwork, they give off a musty odor when your air conditioning is running. Determining the cause with help from HVAC technicians can help you figure out how to get rid of this odor.

Dirty Air Filter

If a dirty air filter is the cause, changing it should eliminate musty odors and a musty AC. Replace your air filter on a regular basis to keep musty smells from returning.

Dirty Coils

HVAC technicians can check your coils and give them a good cleaning to remove debris. This should get rid of bad odors from your AC.

Full Drip Pan

Draining a drip fan that’s full of water can help remove musty odors. This also helps prevent serious mold problems from developing.

Mold or Mildew in Ducts

If you have dirty ductwork, having a professional cleaning done is important. This is an effective way to get rid of mildew or mold inside your ducts so that spores aren’t blown into your home, which can lead to a musty AC.

Incorrectly Sized AC

An AC system that’s too small can lead to musty smells due to moisture buildup and inadequate cooling. Replacing it with the correct-size AC system can eliminate musty odors.
