If you have noticed that the air quality in your home isn’t what it used to be, or that your allergies have been causing you more trouble this year, the problem may be that you have dirty air ducts. Dirt, dust, pet dander, and other airborne particles can collect in your air ducts and be distributed around your home by your heating and air conditioning system.
Even worse, if moisture enters your air ducts, it can create an excellent environment for mold and mildew growth. Mold and mildew spores are then blown into the living areas of your home where they can cause serious health problems.
Not every home needs air duct cleaning. In fact, if your air ducts were properly installed and you use a high efficiency pleated filter that you change regularly, your air ducts should stay clean for years. On the other hand, improper installation, using standard flat fiberglass filters, or failing to change filters regularly can lead to dirty air ducts.
You can inspect your air ducts by removing an air register and examining the inside of the duct with a mirror and a good flashlight. If you see a buildup of dust, dirt and other debris or mold and mildew growth, your ducts may need cleaning. Better yet, ask your HVAC contractor to inspect your ducts during your routine HVAC maintenance visit.
Your HVAC contractor will not only be able to help you determine whether you need duct cleaning, but also will be able to identify leaky or improperly installed air ducts. Many HVAC contractors can also handle your air duct service and cleaning if necessary.
