Dusty, dirty, or clogged air ducts can compromise your indoor air quality and your health! It is important that you have these return air ducts (or the large vents that consist of your home’s air filters) cleaned by professionals on a regular basis. If you don’t, you run a great risk of having contaminants circulated into the air you breathe in at your home or business property. This, in turn, can cause certain types of health complications.
