While the performance of your HVAC systems and ductwork both play a key role in terms of your home’s overall energy efficiency, HVAC system efficiency has come a long way—with technological advancements greatly boosting performance. On the other hand, air duct technology is still in its infancy, and the same goes for air duct cleaning.
What is Air Duct Cleaning?
According to the EPA, duct cleaning generally refers to the cleaning of various heating and cooling system components of forced air systems, including the supply and return air ducts and registers, grilles and diffusers, heat exchangers, heating and cooling coils, condensate drain pans (drip pans), fan motor and fan housing, and the air handling unit housing.
If not properly installed, maintained, and operated, these components may become contaminated with particles of dust, pollen, or other debris. If moisture is present, the potential for microbiological growth—such as mold—is increased and spores from such growth may be released into the home’s living space. Some of these contaminants may cause allergic reactions or other symptoms in people if they are exposed to them.
When Do You Need Air Duct Cleaning?
Experts agree that there are some conditions that warrant air duct cleaning:
• If you see evidence of mold in your home, or it’s visible on the HVAC systems, it’s likely that the mold has extended into the ductwork. Mold causes a host of problems for home occupants, and it can greatly exacerbate symptoms for those who suffer from allergies or asthma. It’s imperative that you schedule duct cleaning if you believe the ducts harbor mold.
• The presence of vermin entering or exiting duct supply and return registers may indicate the need for cleaning the ducts. Vermin leave behind nesting materials and their droppings, and these are particles you don’t want to be inhaling on a regular basis.
• Excessive dust in the ducts is difficult to determine, except if you see large puffs of it released from the supply registers when the air conditioner cycles on.
It’s difficult for homeowners to assess the need for duct cleaning, in part because it’s impossible to visually inspect inside the ducts.
