When should your air ducts be cleaned?

Even though it sounds like something that should be done often, the Environmental Protection Agency (EPA) suggests that you don’t have air ducts cleaned on a routine basis, but only when it’s needed.  However, if you have a fuel-burning furnace or fireplace, it is important to have the ducts checked out for functioning issues to prevent any chances of Carbon Monoxide Poisoning.

How do you know that it is time for cleaning?  One of the main warning signs is when you see mold growing inside of the ducts or on parts of your heating and cooling system.  You may not be able to see the mold growing, so your technician will be able to spot any that is hidden during a full inspection.  Sometimes mold that is found is just a false alarm, so be sure that whomever your hire is experienced.  If you have the type of air ducts that are insulated, they will need to be replaced and not just cleaned.  You also need to have checks for insects and rodents, and be aware of any extra dirt that may be coming into your home.  It is important to also make sure that after cleanings and repairs that your ducts are functioning properly.

Can unclean air ducts affect the health of my family?

Even though the average member of your family may not feel the symptoms of dirty air ducts, people with allergies or other illnesses may be more sensitive.  This will worsen as you allow problems to go without being fixed.  This is another reason it is important to hire a professional.  This can prevent mistakes during cleaning and minor repairs from becoming worse later.

Lower your health and safety risks by cleaning your air ducts. Here’s what you as a homeowner should know.

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 the air system. 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 ductwork. If the duct components were stored outside prior to construction, they may have collected dust, rainwater and even mold before they were installed in a system.

Clean Systems Use Less Energy

Five to seven times a day, the air in your home circulates through the air ducts of your heating and cooling system, carrying with it the dust and debris of everyday living. There are three major parts to your air system:

  1. The supply and return grills;
  2. The interior surfaces of the supply and return vents;
  3. The furnace/air conditioner air handler.

All three components need to be cleaned. 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, you should have a qualified duct cleaning professional apply an EPA-registered biocide every 6 to 12 months.
