Get matched with top thermostat installers and replacers in Vallejo, CA

"Very good experience. Will was great!!! I will hire him again!!"

"Yes withholding until certainty it's fix"

"Great experience"

"I got bids from a *large* number of installers and Red Mountain gave me the best equipment for the price and did a nice job of it despite a few early teething problems that were resolved quickly and competently. But note that the going price in this area for heat pumps is significantly higher than in other areas of the country - regardless of which installer I let bid on my home. In my opinion, given energy price trends, the environmental impact of heating with gas, and having existing solar power on my home, the benefits of a heat pump outweighs the high price in this area, but YMMV. Think thru your position re: BayREN rebates and the recent federal Inflation Reduction Act rebates carefully to make sure you qualify."

"The job was done well and the system has worked perfectly. "

"Needed my duct system under house replaced with better design system that was balanced. Had at least 5 local HVAC Contractors come out to give estimates and Comfort Factor Mechanical estimate was much lower than the "local" companies. Work was completed in 1-1/2 days (two men) which included demo of the old and replacement with new. System works great and would definitely recommend Comfort Factor Mechanical for any HVAC work, repair, or replacement. Eric and Arik are both very knowledgeable about any type of equipment and fully understand a well designed and installed system."
