Your Cotati, California home’s HVAC system processes over one million cubic feet of air every day. That air passes through your chimney flue — picking up and redistributing every contaminant that’s settled inside. In a Mediterranean climate where warm, dry conditions demand constant heating and cooling, the contamination accumulates faster than most Cotati homeowners realize. D&D Chimney Cleaning’s professional Fireplace Repair eliminates this invisible threat.
Cotati’s Mediterranean climate creates specific conditions that accelerate duct contamination:
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 Cotati home and delivers immediate, noticeable results. Every job includes before-and-after camera documentation so Cotati homeowners see exactly what we found and what we removed.
After inspecting thousands of systems across California, technicians consistently find: up to 40 pounds of accumulated dust per home, active mold colonies (especially in Cotati’s Mediterranean climate), rodent and insect debris in over 30% of homes, construction material residues up to 15 years after renovation, and significant airflow restrictions costing 25-40% in excess energy. These aren’t rare cases — they’re the norm in homes that haven’t had professional Fireplace Repair.
The EPA ranks indoor air pollution among the top 5 environmental health risks. In Cotati, California, 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.
D&D Chimney Cleaning provides upfront quotes before any work begins. Our pricing reflects the quality of equipment, certification of technicians, and thoroughness of service. We’re not the cheapest option in Cotati — but we’re the most honest and effective.
