Time To Clean Your Air Ducts
Studies have shown that indoor air can be anywhere from two to five times more polluted than outside air. Most disposable filters remove about 10% of these pollutants allowing 90% to enter the air system, even during the construction of a new home. The pollutants contain dust, pollen, mold spores, animal dander, and much more. These materials collect in the furnace, air conditioner, and duct surfaces, just as they do on the furniture and floor surfaces.
From Where does the Dirt in your Vents Come?
All inside air was once outside air, so all of the dust, chemicals, pollen, insects, and mold spores in the outside air can be pulled into your central air system. People shed millions of tiny dead skin cells every hour. Cooking smoke, household insect sprays, and 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 can find their way into your ductwork. If the duct components were stored outside prior to construction, they may have collected dust, rainwater, and even mold before they were even installed in your system.
Clean Systems Use Less Energy
The air in your home circulates through the air ducts of your heating and cooling system five to seven times daily, carrying with it the dust and debris of everyday living.
There are three major parts to your air system:
- The supply and return grills;
- The interior surfaces of the supply and return vents;
- The furnace/air conditioner air handler.
All three components need to be cleaned periodically. If only one or two of the components are cleaned, the contaminants from the third component will rapidly contaminate the ones that were cleaned. Depending on the amount of contamination and its location, energy consumption could be increased. If the fan blades, evaporator coil, or other control components of the system are heavily contaminated, the system may have to run much longer to cool or heat the occupied space, thereby wasting a lot of energy in the process.
Contaminants Lead to More Problems
Your furniture and floors are cleaned regularly but the duct surfaces are hidden from view and can only be reached by specialized duct cleaning equipment. These pollutants can migrate out into the room again, or become a food source for mold and bacteria, which can thrive in this dark comfortable environment from high humidity or moisture from the air conditioner or humidifiers. Biological growth can release mold spores or toxins into the air system. Once an air system is thoroughly cleaned, it should remain clean for three to seven years if properly maintained. A standard disposable filter only stops about 10% of the airborne contaminants, allowing 90% of the dust in the room to flow back into the air system. To maintain protection against biological growth, your qualified duct cleaning professional may recommend applying an EPA-registered biocide annually.
According to the 55 (NADCA), the average six-room house collects about 40 pounds of dirt, dust, and allergens in its ductwork every year. This accumulation of contaminants greatly decreases your system’s ability to effectively and efficiently operate. All of this can take a large, unwelcomed bite out of your wallet.
