Clean Air
Once you have an air duct cleaning, it should have clean air for 3 to 7 years if properly maintained and a high arrestance filter is installed. A standard disposable filter only stops about 10% of the airborne contaminates, allowing 90% of the dust in the room to flow back into the air system. To maintain protection against biological growth, an EPA registered biocide should be applied every 6 to 12 months by a qualified Clean Air Duct Cleaning Professional.
All inside air was once outside air, so all of the dust, chemicals, pollen, insects and mold spores in the ouside air can be pulled into the clean air system and should be removed during an air duct cleaning. People shed millions of tiny dead skin cells every hour. Cooking smoke, household insect sprays, personal care products are also a source of pollutants. Many construction materials, carpets, wood products and plastics give off pollutants as well. During construction or remodeling activities, many types of dust are produced and find their way into the duct work. If the duct components were stored outside prior to construction, they may have collected dust, rain water and even mold before they were installed in a system.
In addition to the obvious health benefits, air duct cleaning can help you maintain a home with clean air. It also helps you restore HVAC/Air Duct system capacity and lessen running time, resulting in lower heating and cooling bills.
