Causes of Musty Smells in Air Conditioners

The most common reason for a musty smell in your air conditioner is the growth of mold and mildew. Moisture accumulates within HVAC systems, especially in dark and damp areas. This creates an ideal breeding ground for these small particles. Mold and mildew cause unpleasant smells. They can also lead to health issues and hurt your HVAC system.

Another culprit behind musty AC odors is a clogged condensate drain line. This drain is responsible for removing excess moisture generated by the cooling process. If the drain line becomes clogged with dirt, debris, or algae, stagnant water accumulates. This fostering the growth of bacteria and can create a musty smell.

Do you have a dirty air filter? Neglected filters can contribute to musty odors.

Over time, these filters accumulate dust, pet dander, and other contaminants. That creates an environment for mold and mildew growth. As the air passes through the filters, the musty odor permeates into your living space.

  2. Have your AC’s condensate drain line regularly cleaned and maintained to prevent clogs and stagnant water. Some homeowners may be able to do this themselves. You can try flushing the line with a mixture of equal parts vinegar and water or a specially designed cleaning solution. Or you can have this tasked handled by contacting Hanna Heating & Air for professional AC maintenance.
  3. Ensure your home has proper ventilation. Good ventilation helps control moisture levels in your home and reduces the chances of mold and mildew growth. Ensure that exhaust fans in kitchens, bathrooms, and laundry rooms are functioning correctly. Consider using dehumidifiers in high-moisture areas to maintain an optimal humidity level.
  4. Installing UV lights within your air conditioning system can help eliminate mold, mildew, and other airborne contaminants. UV lights disrupt the DNA of organisms, rendering them inactive. Installing an air purifier like Air Scrubber Plus can remove allergens, mold spores, and unpleasant odors from your indoor air.
