Air ducts are conduits for the distribution of cooled and heated air throughout your home. Air ducts, like any other HVAC system, require routine maintenance to operate at peak efficiency.
The National Air Duct Cleaners Association (NADCA) recommends air duct cleaning every three to five years as a general rule.
Certain methods allow for an extension of that cleaning recommendation to 6 to 8 years.
The accumulation of mold and other pollutants that cause allergic reactions may warrant a more immediate air duct cleaning for the sake of your home and family’s health.
