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"

FAQs for thermostat installation and replacement projects in Vallejo, CA

It's often worth replacing your old thermostat with a newer model that can enhance your home's comfort and energy efficiency. Upgrading to a programmable or smart thermostat can save you up to $200 per year on energy bills. Plus, smart thermostats offer convenient features like remote control and learning capabilities, making your home more comfortable and easier to manage.

Signs of a bad thermostat include your HVAC system not turning on when it's supposed to or failing to reach the desired temperature. If the thermostat's display is blank or not functioning properly, it could be malfunctioning. Another indicator is the HVAC system running continuously without shutting off or cycling on and off too frequently. You might also notice uneven temperatures throughout your home, with some rooms being too warm or too cold. These issues suggest that the thermostat is failing and may need repair or replacement to ensure your HVAC system operates efficiently.

A thermostat should last between 10 to 20 years, depending on its quality and how well it's maintained. Over time, dust, wiring issues, and general wear can affect its performance. Even if a thermostat is still functioning after 10 years, you might choose to replace it to take advantage of newer energy-saving technologies and smart home integrations. Upgrading to a modern thermostat can improve efficiency, offer more control over your home's climate, and potentially lower energy bills.

The number of thermostats you need depends on your home's size, layout, and heating and cooling zones. In a standard single-zone HVAC system, one thermostat controls the temperature for the entire home. However, larger homes or those with multiple floors might benefit from multiple thermostats linked to a multi-zone HVAC system. This setup can offer better comfort and energy efficiency: It lets you customize the temperature in different areas, so you're only heating or cooling the spaces you're using.

Replacing a thermostat typically takes a professional technician about one to two hours to complete. If you're swapping out an existing thermostat for a similar model with compatible wiring, the process can be done in less than an hour. However, installing a new thermostat that requires additional wiring, such as a smart thermostat, or moving the thermostat to a new location can extend the time to two hours or more. Complex installations may also involve cutting into drywall or integrating with other home systems, which can add to the duration.

There are a few things that can cause your home thermostat to fail. The most simple one is age and cleanliness. Dirt, grease, dust, and other small particles can clog sensors and cause malfunctions in readings. You may also have a failing power supply and loose connections, and the simplest cause is that it isn't installed in the right place in your home so it can't properly sense air temperature. Repairing a thermostat costs around $210.
