What's Hiding in Your Air Ducts


When it comes to things hidden around your home, you probably worry about surprises your pet may bring in from the yard or snacks the kids hide before dinnertime. But have you ever considered what might be hiding in the winding maze that is your air ducts?


If it's been a while since you’ve had your ducts cleaned (or you’ve never had them cleaned at all), there are several things that could be hiding in them that you may not like.


One of the biggest contaminants that can be lingering in your air ducts is dust. Whether it’s dust that flew off of knick-knacks sitting on your dresser or dust bunnies that form by your return vents, those particles can make their way into your ducts and circulate to the rest of your home every time your unit cycles on.

Pet Dander

If you have furry friends running around your home, you can almost bet that they’ll shed fur and dander all over the place. All that fluff can get pushed into your air ducts and not only circulate around your home but also clog your ducts if enough debris gets caught in the system.

Mold and Mildew

Air ducts, especially those located in your basement or attic, may be subjected to higher humidity levels — and if too much moisture makes its way into your ducts, mildew and mold can begin to grow. Talk about gross!


Germs and other bacteria can make their way into your air ducts and linger there as long as your ductwork goes uncleaned. This can be particularly unsettling if someone in your home is susceptible to illness or has respiratory issues.
