Here’s something most Mercer Island 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 Washington’s cool maritime climate — where persistent dampness and mold risks adds even more contaminants — that’s a significant health and efficiency problem. D&D Chimney Cleaning provides the deep, professional Chimney Cap Installation that your filter can’t deliver.
Mercer Island’s cool maritime climate creates specific conditions that accelerate duct contamination:
A common misconception among Mercer Island homeowners: “I change my filter regularly, so my ducts are clean.” The reality? Standard filters capture only 10-15% of airborne particles. The rest settles in your chimney flue — building up layer after layer with every HVAC cycle. In Washington’s cool maritime climate where persistent dampness and mold risks adds constant new contaminants, your filter is fighting a losing battle without professional backup.
It’s not just about air quality. Dirty chimney flue forces your HVAC system to work harder, increasing energy bills by 25-40%. In Mercer Island, where cool, wet conditions drive heavy HVAC use during cooling season, that translates to hundreds of dollars wasted annually. Factor in premature system failure — a new HVAC unit costs $5,000-15,000 — and preventive Chimney Cap Installation becomes one of the smartest investments a Mercer Island homeowner can make.
