Needed to have my heater upgraded to something more efficient. After calling in I was fit in immediately and a new unit put in within the week. It was difficult work for the 2 gentleman that arrived, but they worked quickly and left the place cleaner than when they arrived. I must commend the young gentleman Kyle on the professional quality work and exceptional customer service. He was extremely polite. I highly recommend this company, they employ quality professionals and I will continue to use them as the need arises.

Totally professional. From the front desk to completion of project. When they were putting in the new air/furnace system, I would forget they were here because they were so efficient and quiet.

I cannot believe this company. They quoted a new furnace for my home in Sonoma in December 2020 for $4700. In May 2021 i contacted them to proceed with the installation. However, i was told the new price would be $9900. When i inquired how the price could increase more than 2x Scott Peterson, the owner, stated there had been 2 cost increases from the manufacturer of 7%. Really, so $4700. plus 14% now equals $9900?
When i questioned his price increase he responded that gas now cost $4/ gallon. Needless to say i will not be hiring this company. I guess their business philosophy is just get away with whatever you can and hope the customer goes along with it.

My ductwork was in shambles. This Company not only gave me the best price, they also were the most professional and polite staff I have ever seen! They were clean, cordial, respectful of my house and pets and knew what they were doing! Especially Kyle, who went the extra mile by leaving me a note regarding their progress and when I could expect them to return and finish. This is an all around great Company, use with confidence!

I recently had my furnace replaced. I got 3 estimates and Petersons was significantly the best price by far for the same work to be completed. From the estimate to completion of the project the customer service, quality of work, and kindness of the employees was 5 star. The 2 men that came to the house were polite and respectful of my home. Thanks to the whole team!
