Our technician, Tom, was outstanding. He was thorough, thoughtful, explained the work to be done, the cost, options, and seemed to take the minimum amount of time to complete the work. The technician’s helper, who came along with Tom, was also a great asset. It was a wonderful experience for us. But, it always is when we call James A. Wheat & Sons.

Technician was prompt, polite, and obviously new his business. He thoroughly checked our fireplace insert, and made acheck for CO in the room. His work reassured us that the insert and its inlet-outlet system had not suffered earthquake damage. That's just what we needed to know.
