The state of our air vents greatly impacts the air quality inside of our homes, from spreading contaminants to harboring odors. In this post, we discuss the causes and solutions to a musty odor from air vents.

What Causes a Musty Odor in Air Vents?

As air cycles through the air vents in your home, dust, pollen and other contaminants tend to travel with it. Along the way, these particles are deposited throughout your air ducts and air vents and left to build up over time. This build-up can lead to a musty odor, decreased air quality and an uptick in allergy symptoms. Common offending contaminants include:

• Dust, pollen and dander.
• Bacteria.
• Mold, mildew and mold spores
• Tobacco smoke by-products.
• The feces, nesting materials and/or remains of rodents or insects.

Getting Rid of Musty Odors in Air Vents

• For immediate relief, baking soda can be used to absorb unpleasant smells. Place baking soda in a dish and directly in the air duct.
• Clean or have your entire HVAC system cleaned top to bottom. Dirty evaporator coils, a clogged condensate drain line and dirty filters can all contribute to a musty odor circulating through your home.
• Thoroughly cleaning air ducts and vents, as well as cleaning/replacing all filters frequently is the best way to get rid of and prevent musty odors.

When to Clean Air Ducts

If you notice any of the following, it’s time to call a professional:

• Visible mold inside of air ducts.
• Persistent musty odors.
• Insect and/or rodent infestations, or evidence of their presence, such as droppings or nesting materials.
• Those who live in the space frequently suffer from allergies, sore throats and coughing.
