Celebrating 80+ years of service in the great state of Michigan

"Very thorough...explaining everything he was doing..."

Brian gave us excellent service when our furnace stopped working in the middle of a cold spell. He was polite and had a great sense of humor which I appreciate in a person. He was very thorough in checking out the problem, explaining everything he was doing. I was able to ask him questions and he answered all of them for me. He was at the house for 3 hours and fixed the problem efficiently. I will definitely use Thornton & Grooms again and hope that they send Brian out to the house to fix the problem!
