Whether you’ve just moved to Portsmouth or you’ve lived here for decades, there’s one thing every New Hampshire homeowner should know: your chimney flue system is collecting and distributing contaminants every time your HVAC system runs. In Portsmouth’s humid continental climate, where cold, snowy winters keep your system running for extended periods, the accumulation is accelerated. D&D Chimney Cleaning provides the professional Dryer Vent Cleaning that resets your indoor air quality to where it should be.
The EPA ranks indoor air pollution among the top 5 environmental health risks. In Portsmouth, New Hampshire, common duct contaminants include mold spores that trigger severe respiratory reactions, dust mites that cause year-round allergies, volatile organic compounds off-gassing from household products, pollen and outdoor allergens pulled inside through your HVAC intake, and pet dander that embeds in duct linings. Your family breathes this recirculated air for up to 22 hours daily.
We connect our truck-mounted vacuum system to create negative pressure throughout your entire duct network, then systematically agitate and extract contamination from every supply line, return line, register, and HVAC component. The process takes 3-5 hours for a typical Portsmouth home and delivers immediate, noticeable results. Every job includes before-and-after camera documentation so Portsmouth homeowners see exactly what we found and what we removed.
Open one of your vent registers and look inside. That dark coating is years of accumulated dust, dead skin cells, pet dander, pollen, mold spores, and worse. Now multiply that by every linear foot of chimney flue system — typically 100-300 feet for an average Portsmouth residence. Your HVAC pushes air through all of it every single day. In New Hampshire’s humid continental conditions where heavy heating seasons and moisture is ongoing, this buildup is more aggressive than in milder climates.
According to NADCA, the average six-room home generates 40 pounds of dust per year. The EPA estimates Americans spend 90% of their time indoors. For Portsmouth families, that means breathing recirculated air that passes through contaminated ducts thousands of times. In New Hampshire’s humid continental climate, moisture and temperature conditions accelerate contaminant buildup significantly compared to other regions.
