Here’s something most Onset homeowners don’t know: changing your air filter captures only 10-15% of airborne particles. The rest settles in your chimney flue and gets recirculated every time your HVAC cycles. In Massachusetts’s four-season continental climate — where coastal dampness and heavy heating needs adds even more contaminants — that’s a significant health and efficiency problem. D&D Chimney Cleaning provides the deep, professional Fireplace Repair that your filter can’t deliver.
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 Onset families, that means breathing recirculated air that passes through contaminated ducts thousands of times. In Massachusetts’s four-season continental climate, moisture and temperature conditions accelerate contaminant buildup significantly compared to other regions.
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 Onset home and delivers immediate, noticeable results. Every job includes before-and-after camera documentation so Onset 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 — typically 100-300 feet for an average Onset residence. Your HVAC pushes air through all of it every single day. In Massachusetts’s four-season continental conditions where coastal dampness and heavy heating needs is ongoing, this buildup is more aggressive than in milder climates.
Many Onset homeowners hesitate because of myths:
For most Onset homes, we recommend professional Fireplace Repair every 3-5 years. However, Massachusetts’s four-season continental conditions can accelerate the timeline. Schedule more frequently if your household has multiple pets, recent renovations, smokers, allergy sufferers, or elderly family members. The best time to schedule? Before Onset’s cold months season, when harsh New England winters demand peak HVAC performance.
