What’s Hiding In Your Home’s Air Ducts?

Inspecting a Home Air Vent for Maintenance

When was the last time you took a look inside your home’s air ducts? If it’s been a while (or never), here are a few things you might find hiding in them…


Did you know that the average three-bedroom home generates more than 40 pounds of dust per year? Some of this dust settles on your furniture, but a lot of it collects in your air ducts. This accumulation of dust can hinder air flow and reduce the efficiency of your HVAC system.

Animal Dander

Not to be confused with pet hair (which can also collect in air ducts), dander is small flakes of skin. Virtually every animal sheds dander, including cats, dogs, birds, and rodents. Dander possesses a unique, jagged shape that allows it to stick onto our furniture, clothes, and inside our air ducts. It can even be found in homes without pets.


If you suffer from spring allergies, you know that pollen is something you want to avoid at all costs. However, what you may not know is that this pollen could also make its way into your home via your air ducts. If your HVAC system has a fresh air intake pulling in air from the outside, it is giving pollen easy access to your house.


The combination of darkness, moisture, and food (read: dust and pollen) make your air ducts the perfect breeding ground for mold. Mold isn’t just damaging to your house, it can also trigger allergic reactions, asthma attacks, and respiratory infections.

These are just a few examples of what you might find lurking in your air ducts. Once these pollutants make their way into your ductwork, they can use it as a transportation system to spread throughout entire your home and compromise your indoor air quality.
