We live in a world where healthy living has become a way of life. We diet and exercise to make ourselves feel better. We have also taken on environmental issues to make our world a cleaner and safer place to live. Yet the most overlooked issue is the air that we breathe.
The Environmental Protection Agency claims that Phoenix indoor air quality has been found to be up to 20 times more polluted than outdoor air. Now consider that most people spend about 60% to 90% of their time indoors... The facts can be quite alarming.
Dirt, dust, mold, pollen and animal dander are re-circulated through our air ducts every time we turn on our heat or air conditioner. Combine this with moisture and you have the ideal breeding ground for fungi, germs and household mold. Studies have confirmed that some diseases, including salmonella, strep and legionnaires disease are spread by contaminated air ducts.
It is important to note at this time that if you choose to do air duct cleaning, the entire HVAC system needs to be cleaned, not just the air ducts. Cleaning the air ducts without cleaning the HVAC unit itself is not acceptable. HVAC system cleaning is just that: removing dirt and debris from the ductwork and air moving equipment. Current cleaning standards recommended by the National Air Duct Cleaner's Association (ACR 2005) require that non-porous air conveyance system surfaces must be visibly clean and capable of cleanliness verification tests.
