How To Eliminate Musty Smell From Air Conditioner

The nasty smell coming from your HVAC unit can be a big issue for homeowners who just want to relax in their homes during summer. While there can be multiple reasons for the smell, you should know how to eliminate them from the air conditioner.

In this blog, our experts have listed the best ways to get rid of this unpleasant air conditioner smell to help homeowners remove the musty odor and restore their home’s pleasant environment.

Ways To Eliminate Musty Smell From Air Conditioners

⇒ Replace Air Filters

Dirty air filters are a common reason for a musty smell in your HVAC unit. It’s because, after a while, air filters get so dirty that they no longer work. You should change your air filters every two to three months to prevent them from getting clogged.

So choose the right filter for your air conditioner and replace the old one with it. Doing so will remove the musty odor from your HVAC and make it smell good once again.

⇒ Clean the HVAC Coils

The function of HVAC coils is to exchange heat. So they regularly come into contact with outside moisture to do that. It leaves them susceptible to damage from moisture and even mold growth. To prevent allergen and mold build-ups on the coils, you should clean them at least once a year.

⇒ Maintain the Evaporator Coil

Dirty and frozen evaporator coils are another reason for the musty air conditioner smell. Both conditions can lead to mold growth on your AC, which is the source of the odor.

So, use a sanitizer to clean the coils in a way that kills the mold without damaging the evaporator coil. You can do this by removing the metal fins to access the evaporator coils and spraying sanitizer on them. Before doing this, clean any dirt and dust with the vacuum cleaner.

⇒ Drain the Condensate Line

The chances of mold growth increase if the drain pipes get clogged as the water backs into the pan. This moisture is the most likely reason for the unpleasant smell coming from your HVAC unit.

You can solve this issue by using a dry-wet vac to de-clog the drain. Use the machine to remove the excess water in the drain and clean it. If this fails, you need to call in experts to unclog the drain.

⇒ Clean the Air Ducts

Accumulated dirt, grime, and allergens inside the air ducts reduce the air quality of your home and cause unpleasant odors. The best way to prevent this is to get the air ducts cleaned by professionals at least once a year. It will keep the air ducts clear and prevent the debris from gathering inside and causing the musty smell.
