With Pepperell’s August heat pushing HVAC systems to their limits, Kevin Chen Air Duct Cleaning LLC reminds homeowners to inspect air ducts now. Dust, pollen, and summer humidity can clog systems, reduce efficiency, and even pose fire hazards—especially in older homes near Nashua River or on Main Street.
Check these 3 duct issues before the next heatwave hits Pepperell
Before Pepperell’s next 90°F day, walk your attic or basement and shine a flashlight into your return vents. Look for thick dust blankets or black streaks—signs of mold or creosote buildup that can spark fires. Also check for gaps around duct joints; loose seams near the old Pepperell High School area let conditioned air escape, wasting energy. If you spot any of these, call us at contact for a free estimate. We’re licensed, insured, and serve all of Pepperell and nearby towns like Groton and Townsend.
Should Pepperell homes near the Nashua River worry about duct moisture?
Yes—summer humidity plus duct leaks near the Nashua River can create perfect conditions for mold inside your walls. If you smell musty air or see condensation on supply vents, your ducts may need cleaning and sealing. We use negative-pressure systems to remove mold spores safely and restore airflow.
