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.

Thomason Mechanical exceeded our expectations for multiple reasons; professionalism, speed of providing our estimate, installation, cleanliness and friendliness.
