What Lives In Dirty Air Ducts?


Air: 21% oxygen, 78% nitrogen, 1%…erm, do you really want to know?

Well if you want a clean house and a healthy family then it’s important to know what’s in the air in your home and this all has to do with your air ducts. The average home has between 30 and 90 linear feet of duct work, which is quite a lot of places for nasty contaminants to lurk. Cleaning your air duct system is a great idea for your home to freshen your environment.

Air ducts carry both A/C and heat throughout your home, meaning they are constantly in use. Throughout the years, many things can build up inside air ducts, but dust is certainly the most likely candidate. A 1600 square foot home produces 40 pounds of dust a year. Now, this isn’t all in your air ducts, but your air ducts do affect the circulation in your home and how this dust is distributed. You may think you are allergic to this dust, but that’s not 100% accurate. Inside the dust lives these tiny creatures called dust mites and it’s actually these animals that you are allergic to. Having your air ducts cleaned can reduce the amount of dust floating around your home, cutting off the food supply for these dust mites and making life easier for allergy sufferers.

Another thing that can be found in dirty air ducts? Mold. Some mold can be easily cleaned out of your ducts if it’s within eyesight/reach, but if there’s mold where you can get to it, you should probably assume there’s mold in ducts that you cant see. Mold likes moist environments and if it starts growing anywhere in your home, mold particles can become airborne and be circulated into your air ducts. This obviously compounds the problem since mold can now be spread to any corner of your home. Inspect and maintain your HVAC system regularly to be sure the machinery is in good condition and all fluids or condensation is draining properly.

The third most common thing found inside your air ducts? Animals. Rats, mice, raccoons, and squirrels can easily enter your air duct system if they find their way into your attic (which they particularly like to do in winter time to escape the cold). A single animal can cause thousands of dollars in damage if it chews through your ducts. Holes in ductwork mean the air is no longer circulating properly and your house isn’t being cooled or heated efficiently, driving up your energy bill. Hearing noises such as gnawing, scampering, or squeaking coming from your walls or ducts is a sure sign of an infestation. You may also experience bad smalls coming from your ducts if an animal crawls in and doesn’t make it out (if you know what I mean).

Getting your air ducts cleaned can dramatically affect the quality of the air in your home. Not only does it ensure no contaminants such as mold or dust are not being circulated, but it also keeps your HVAC units working efficiently. The cleaning process starts with your Sears technician inspecting your system and explaining how they will be cleaning your ducts. Protective coverings are placed around the home and return air vents are sealed for the vacuuming. Truck-based equipment uses high powered air to loosen debris inside your vents before a powerful vacuum takes it directly out of your house into a containment unit, leaving you with only the fresh, pure air you and your family deserve. Doesn’t that sound nice? Sears Clean can help you with that today!
