1. What air duct cleaning actually does (and why Pepperell homes need it more)
Cleaning your air ducts gets rid of dust, dirt, mold spores, and allergy triggers from the tubes, vents, and grates in your heating and cooling system. In Pepperell, where many homes are older and humidity lingers even in fall, ducts act like a filter trap, collecting pet dander, pollen, and even lead dust from older paint. Without cleaning, this buildup forces your furnace or AC to work harder, raising energy bills and shortening equipment life. The U.S. Environmental Protection Agency notes that dirty ducts can circulate up to 40,000 times more dust than clean ones, meaning your Pepperell home’s air quality suffers long before you see visible dirt. Thompson Air Duct Cleaning Co. targets these hidden contaminants with HEPA-vacuum systems and antimicrobial treatments, especially critical after renovations or when moving into an older Pepperell property.

Black, green, or gray spots inside vents or on ductwork mean active mold growth. 6. Increased energy bills.
