"This project needed 2 people. My old refrigerator was extremely heavy. I took a photo and submitted it Angie’s list. I would of thought a large stainless steel fridge would almost impossible to move with only one pro. My only complaint is that my old fridge is sitting outside because it was too heavy and dangerous for the pro to move to the garage himself."

"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."

"We had to get our Cooking range hood serviced that had just stopped working. NEXT HVAC promptly scheduled John T to come the same day. We were also updated about the schedule and ETA proactively. John was on time, kind and very knowledgeable. He diagnosed and fixed the problem in about 30-45 minutes. Great professional service!"

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!"

Humidifier Repair questions, answered by experts

For certain repairs, a plumber may be able to help fix a humidifier, but HVAC technicians are typically the go-to professionals. The most common humidifier repairs that plumbers handle are humidifier water shutoffs, solenoid valve maintenance, and evaporator pad replacement.

NATE (North American Technician Excellence) certification is not legally required for HVAC technicians in most areas, but hiring a professional with this certification is highly recommended. NATE-certified technicians demonstrated their expertise and proficiency in different types of HVAC systems, offering assurance of quality service. It's a voluntary certification, yet it indicates a commitment to professionalism and ongoing training. Choosing a NATE-certified technician often means you're working with someone who is up-to-date on industry standards and best practices, which can lead to better service, energy efficiency, and long-term cost savings.

Whole-house humidifiers work, but the home itself determines their efficacy. If you have a drafty house or an old home with wooden floors that leak air and moisture, the humidifier must work much harder to keep moisture levels constant. Because of this, we recommend doing an air test of your home to determine the best type of humidifier and any work that needs to be done to install it. 

Whether you’re facing significant humidifier repair costs or it’s time to replace your humidifier altogether, it’s understandable to question whether the expense is worth it. Still, there are many benefits of whole-house humidifiers that you might miss, including improved indoor comfort, improved breathing and sleep, better hair and skin, and even increased home value. Either way, the answer is subjective, so it’s helpful to evaluate your home’s humidity without the unit running and give it a few weeks to see if you notice a difference.

One handy thing about whole-house dehumidifiers is, once installed, you don’t have to worry about placement or changing the dehumidifier’s position. But if you are using a portable dehumidifier, we suggest keeping it away from walls, vents, and furniture. It needs a central, unobstructed spot with access to lots of air to do its job.
