Air Duct Cleaning Across New Hampshire
Armstrong provides NADCA-certified air duct cleaning to homeowners across New Hampshire — from Amherst, Atkinson, Auburn and more. Our New Hampshire crews know the housing stock in this region and tailor every visit to your ductwork, your concerns, and your schedule.
Over time, dust, pet dander, pollen, and construction debris collect inside your ductwork and recirculate every time your system runs. Our source-removal process uses powerful negative-air equipment and agitation tools to clear it out — not just push it around.

Key Benefits
NADCA Source Removal
We use the NADCA-standard negative-air method with agitation tools to physically remove buildup — not just mask it.
Cleaner, Healthier Air
Removing dust, dander, and allergens from your ducts means fewer irritants recirculating through your home.
Better HVAC Efficiency
Clean ducts and coils let your heating and cooling system move air freely, which can lower energy bills.
Before & After Proof
Every job includes a digital report with before-and-after photos so you can see the difference.

After seeing a terrifying expose on dryer fires, we decided to have our vent cleaned out after 20 years. Two technicians showed up , both were amazingly professional. Austin took the lead explaining all of our options and how best to go about cleaning Once they finished and cleaned up, it was if they had never been there Definitely would recommend highly and totally like keeping it local

I hired Armstrong to clean my ductwork. They were great from start to finish! Well detailed quote. The service team was on time, courteous, thorough and cleaned up after themselves. They even provided before and after pictures of their work. I would recommend them to anyone!
