Message from the Owner/ Founder: “As a third generation heating and air technician and retired 20 year veteran of fire and public safety, I wanted to create a service company that you could count on for its integrity and professionalism. When our service technicians arrive at your home, we want you to feel the same level of confidence and trust you get from a firefighter arriving at your home to help when you call 911. Our service technicians are professional, courteous, and well trained. I am comfortable allowing them into the homes of my families and friends who are firefighters, police officers and the public. Thank you for the opportunity to service your comfort needs and believing in our company. We look forward to a continued long relationship. Warm regards, Harry Abbott” Comfort Energy Inc is a full service provider of quality air conditioning and heating repair and installation. . Locally owned and operated, with over 30 years of experience. We are proud members of the Nexstar network of contractors. We specialize in helping homeowners make informed decisions to best meet your family's comfort needs. Spanish and Japanese spoken.
"We had a wonderful experience with Comfort Energy! The service person, whose name was Chance, did a thorough evaluation of the problem with a focus on saving us as much money as possible, to either repair or replace our 30-year-old heat furnace. He quickly determined that our inlet filter was too dense (it was a Merv 11 and should have been a Merv 8) and that that was probably causing the heater to go off an on every 5-10 minutes. He then tested and confirmed his hypothesis. He also performed a CO test to make sure there wasn't anything more serious going on. Finally, he gave us a good idea of replacement options, which we should probably do before the next Winter, but not necessarily right away. All in all, this is exactly the kind of assessment we needed, and it cost orders of magnitude less than what was estimated by the first service company we had come out. Chance was great, and Comfort Energy is our go-to for heating and cooling service and/or installation from now on."

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!"

"Called this company for their $77 dollar, which they advertised with a flyer, for a tune-up and cleaning for my heating system. They are a Hayward company and I was told that our Castro Valley home was not in their service area. I bet if I called to buy a new heater they would be out in a day."

Central a/c service or repairs FAQs
Yes, a once-a-year tune-up keeps the system efficient and helps it last longer. During the visit, a technician cleans coils, checks electrical connections, and swaps or cleans the filter. Catching small issues now stops bigger, pricier failures later, so that a quick appointment saves money and stress over the life of the unit.
Changing your AC filter every 30 days is necessary to maintain optimal performance and high indoor air quality. Regular filter replacement prevents dust buildup, ensures efficient airflow, and protects the system from stress that could lead to costly repairs. This disciplined maintenance routine not only boosts energy efficiency but also prolongs the lifespan of your unit by safeguarding its critical components.
An HVAC service plan is worth the cost, especially if you forget to schedule maintenance on your own. A service plan locks in yearly (or twice-yearly) visits, allowing a professional to identify small problems early, clean key components, and maintain energy efficiency. Many plans also include minor repairs or priority scheduling, which can pay for themselves if an unexpected issue pops up.
In a pre-season service visit, your technician gives your system a top-to-bottom check before peak season hits. Expect a filter change, thermostat test, condenser-line flush, electrical-connection check, and coil cleaning. They also tighten loose parts and make minor adjustments so the unit fires up without surprises when temperatures swing. That quick tune-up cuts the risk of mid-season breakdowns and keeps energy use in line.
