What could possibly be in my air ducts?
What could be in your air ducts are the same things that are in your vacuum cleaner bag. Picture a full vacuum cleaner bag. This bag may contain any or all of the following debris: carpet fibers, skin scale and hair, dust mites and their feces, food crumbs, pet food and cat litter, mold and mildew, drywall dust and new construction debris, insect and rodent excrements and remains, bacteria and viruses, pet hair and dander.

Now picture 2-4 grocery bags full of this same material. This is an accurate picture of how much debris we vacuum out of an average size home’s air duct system.

Dust and dirt continually accumulate on the inside surfaces of your ductwork. This environment provides the nutrients for mold, bacteria, allergens and fungi to reproduce and grow. Every time your system’s fan goes on, it forces this contaminated mixture into the air you breathe.

In addition to cleaning the air you breathe, the build-up of household dust on furniture and your belongings is dramatically reduced.

Clean ducts also increase the efficiency of your heating and cooling system, cutting utility costs and potential system breakdowns.

How often should the duct be cleaned?
Every three to five years is probably often enough. If someone in your family has asthma or chronic allergies, yearly cleaning may be beneficial. And you don't need to worry about remembering when it's time again - we'll be sure to let you know when to schedule another cleaning.

Will it make a mess?
Andrews Air Duct Cleaning technicians are finicky about cleanliness. The powerful vacuum pulls dislodged dust and dirt right out of your house. We protect light colored carpeting with drop cloths, and of course our technicians will clean up when they’re finished.

Is it really worth the money?
Our customers think so. Your entire family will breathe easier-even more so if someone has asthma, allergies, or other respiratory ailments. You’ll dust less often. Your furnace will operate at its peak efficiency.
