Testimonials
Thomason Mechanical was knowledgeable, prompt and very reasonably priced. He had the required parts with him and completed the repairs immediately. Very important to me, (and should be conveyed to all of your people), He gave me concise and truthful information - he didn’t try to “B.S.” me as so many furnace repairmen can. I will recommend this company whenever possible.

The Thomason Mechanical & Design people were very friendly and very helpful in explaining the system. We are very happy with our new Trane furnace and air conditioner and the company is great to work with.

Furnace Repair in Marin and Sonoma

furnace company sonoma county I was very very satisfied with the service & installation of my new furnace. The work crew was very neat and clean. They were also very knowledgeable. They cleaned up after the installation and answered all my questions. I would most definitely recommend them to my friends.

Tom Thomason was professional and friendly. It was a pleasure working with this contracting company. The air conditioning unit is working great!
~Andy Jones, Windsor

The contractor provided knowledgeable experience and service the likes of which we thought had been long forgotten. We feel that Trane made a wise decision in making them one of the visible choices for my zip code (on the website). They are a highly professional business that we will recommend.

Lin was outstanding in selling me the Trane system, taking time to explain how it would work. Steve, the installer, was also outstanding and very knowledgeable of the HVAC system, (especially for his age “21”). He also took his time explaining the operation of the thermostat. Overall, he was very friendly and professional through the entire installation. I have already recommended Thomason Mechanical to one of my neighbors who will be replacing her system, and will continue to do so.
