If you have been dealing with musty smell in your home, Filti has some helpful tips. Read more for the top tips on how to clean up the air and remove foul odors by performing simple routine cleaning, HVAC checks, and maintenance.

What Causes Your Air Conditioner To Smell Musty?

Clogged Filters

Air conditioning systems trap tiny particles that settle in the filters over time and cause mildew growth when exposed to moisture. If your air conditioner’s filter is dirty and clogged, this may result in your AC smelling musty.

Clogged Drain Lines

The condensate drain line helps in removing the condensation generated by the coils. A clogged drain can promote the growth of mildew around the coil and cause your air conditioner to smell musty.

How To Get Rid Of Musty Smell In HVAC

 Air Filter

Replacing the air filter is important for regular ac maintenance. If you fail to replace the ac filter on a regular basis, it could cause many issues within your HVAC system. Be sure to keep a log of when to replace your ac filter. It is recommended that you replace it once every three months. This keeps the smells and odors from traveling throughout your home.

Clean Coils

Coils are responsible for heat exchanges in the HVAC system and come into regular contact with the outside air circulating throughout, so it’s essential they are kept clean. HVACs have two main sets of coils: the interior, evaporator coil; and the exterior, condenser coil. However, it’s most likely that a dirty evaporator coil is the culprit. To alleviate smelly odors, as well as prevent a build-up of allergens, dust, grime, and spores in the HVAC’s coil system, be sure the coils are routinely cleaned.

Check For Excess Moisture

A common cause for a home’s mildewy smell is a clogged condensate drain line. As condensation forms on evaporator coils, the water drips into the condensate pan and down the drain line, taking with it the dirt that has fallen into the pan. Over time, neglected evaporator coils allow the excess moisture to create perfect conditions for mold growth in the condensate pan.

Our professionals check and clean condensate pans on routine visits. However, if it’s been a while since your HVAC was last serviced and excess moisture is noticed, clean the clogged condensate pan by removing water from the drip pan with a towel or vacuum. Then, remove and cleanse the drip pan with mild soap to clear any algae or contamination.
