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!"

Aim for indoor humidity between 30% and 50%, with the sweet spot around 45%. That range keeps mold, dust mites, and musty odors in check while protecting drywall and woodwork. Staying in the zone also helps your HVAC system run more efficiently and supports healthier air for you and your family year-round, during hot summers and cold winter months.
With routine filter changes and coil cleanings, most whole-house units run for eight to 15 years. Heavy use, poor air quality, or bargain-bin equipment can shorten that span, while a well-maintained, high-quality model often makes it to the upper end of the range. Ask your installer about recommended service intervals to get the most mileage from your investment.
It depends on your climate. Homes in cold, dry regions can often shut the dehumidifier off once winter sets in. If you live in a warm, humid area—or your house tends to trap moisture—you may need to keep it running year-round. Use a simple hygrometer: if readings stay below 50%, give the unit a rest. Just remember to restart it when humidity climbs again to avoid mold and condensation.
Dry air feels cooler, so your AC doesn’t have to work as hard. By stripping out excess moisture, the dehumidifier lets you raise the thermostat a few degrees without losing comfort. A shorter AC runtime reduces electricity use and can shave a noticeable amount off your summer power bill. Energy-efficient models further enhance those savings.
If your home is under about 2,000 square feet, a well-placed portable unit can handle the load. Just remember they’re less efficient and need hands-on upkeep—think emptying tanks and cleaning filters. If you prefer set-and-forget convenience or plan to expand your living space, a whole-house model still offers better long-term comfort and lower energy use per square foot.
