The first home HVAC system air filters were actually designed to keep particles out of the air handler of the heating and air conditioning equipment. If large particles were to move from the air in your home into the blower fan, it could hinder performance, causing the fan to slow down and potentially jamming the motor. Dust can also clog the burners of a furnace or keep the air conditioning coils from absorbing heat effectively.
Just like the air filter in your car, the air filter in your air conditioning and heating system protects the parts of your unit from damage. But today’s filters serve a second purpose, eliminating unsafe particles from the air that you breathe. Because air cycles frequently through the ducts, it’s important to have some form of defense against pollutants that could aggravate allergies and irritate the lungs.
But a standard air filter doesn’t guarantee that all of the contaminants that could enter the ducts are deterred. In fact, most home air filters are ineffective at removing even the most common home contaminants, such as mold spores, which could then move into the ducts. Many of these contaminants stay dormant in the ducts for a while, infiltrating the home from time to time and irritating household members’ allergies and other respiratory conditions.
The following contaminants may be contained within your duct system. Experts recommend scheduling duct cleaning once a year in some cases, or as often as your technician recommends it.
- Dust mites: Dust mites thrive in warm, humid areas, and the ductwork may be a perfect location. As one of the most common allergens found in homes, dust mites can irritate those with allergies and may even trigger asthma in children.
- Pet Dander: You may not have a pet in your home due to your allergies, but what about the homeowners who came before you? Duct cleaning is especially important for people with severe allergies, especially if they seem to act up often.
- Bacteria: There could be some harmful bacteria present in the ducts that could make family members ill, particularly those with immune disorders.
- Mold: Finally, mold survives on wet surfaces, like the indoor air handler of your air conditioning system, and could spread to the ducts.
