Serving Santa Rosa for over 30 years, we are proud to be a Carrier Factory Authorized Dealer and were honored to be win the Carrier President's Award Winner in 2008. A family-owned business, we employ some of the BEST people in the HVAC industry with a combined experience of over 50 years. Our technicians are certified by the North American Technician Excellence (NATE)organization. We are a member of Local Sheet Metal Union 104 which means our employees are highly trained, educated and well skilled in all makes and models of heating, ventilation and air conditioning systems. We are also members of the Santa Rosa Chamber of Commerce, North Coast Builders Exchange, and Marin Builders Association. We provide respectful, dependable, honest and reliable customer service for any job, no matter how large or small and our pricing is competitive and fair with no hidden or surprise costs. Simpson takes the family approach to business by having the estimator conduct all of our free estimates, not an aggressive sales person. This provides all of our customers with the confidence that every system is designed and installed properly. It is our commitment to ensure that all of our customers are completely satisfied. We are your one stop source for all of your heating, air conditioning and air quality needs.
"Simpson Sheet Metal HVAC was recommended by a friend who had just had a heat pump and mini-split system installed and raved about the company and the individuals to me. I had already gotten three quotes from other area companies (I was in need of replacing ancient and malfunctioning baseboards and had been using a Quadrafire wood stove to heat my house), but decided to get a quote from Simpson and it turned out to be the lowest, with the best warranty terms, and the most "hand-holding" in terms of permit, rebates and payment. I also love the fact that it's a union shop because that means a well-educated and well-treated employee. Lead installer Jose and assistant Chino did a fabulous job, and as others have said, they left everything perfectly clean and also answered my many questions with patience and good humor. John Roncone managed the job and designed the system, and has been an amazing communicator as well. Nothing but raves for Simpson! What a relief!"

"Jeff has come to the rescue twice to my new build home. He came the first time in the middle of summer when the a/c would start up. It was just the fan running. He was able to repair the unit same day. Recently, the same thing happened but with our heater. The burners were not lighting up. Apparently the builders never put the cover on and they got clogged with dust and debris. He was able to get our heater working and cannot be more thankful. He was able to fix a couple of things in the attic that the builder just slapped on. I’m sure this system will not stand the test of time, especially here in Vacaville so I’ll trust New age when it’s time to replace this system"

Most standard ductwork rerouting projects require between one and three days for completion, though complex installations may extend to a week. Factors affecting the timeline include accessibility of work areas, whether walls need opening, and the discovery of unexpected issues like asbestos or mold.
Projects involving multiple rooms or requiring extensive modifications naturally take longer. Scheduling during moderate weather seasons minimizes comfort disruptions while your system is temporarily offline.
Properly redesigned ductwork can significantly improve energy efficiency in many homes. Inefficient duct layouts may waste 20% to 30% of conditioned air through excessive length, leaky connections, or poor insulation.
Professional rerouting creates more direct airflow paths, eliminates leakage points, and often includes improved insulation. These enhancements allow your HVAC system to operate more efficiently, potentially reducing energy consumption while improving overall comfort throughout your home.
If you suspect asbestos in your ductwork or surrounding materials, immediately stop any work and contact a certified asbestos inspector. Asbestos testing services cost between $250 and $700 to confirm the presence of this hazardous material. Professional removal, if necessary, ranges from $700 to $2,200 depending on the affected area. Never attempt to remove or disturb potential asbestos materials yourself, as improper handling creates serious health risks through airborne fiber release.
Permit requirements for ductwork modifications vary by location. Many municipalities require permits for significant HVAC system changes, especially those involving structural modifications. Consulting your local building department before beginning work ensures compliance with regulations.
Working without required permits can lead to complications, including potential fines, insurance coverage issues, and disclosure requirements when selling your property. Professional HVAC contractors can handle permit applications as part of their service.
