Celebrating 85+ years of service in the great state of Michigan

Extremely pleased with the attention to detail, professionalism, and clean-up…”

"Extremely pleased with the attention to detail, professionalism, and clean-up. Ahmad H. was the fabulous technician who installed my new furnace and air conditioner. He was very thorough and made sure everything worked perfectly before he left. The township inspection was completed today; he said everything looked good. All the work was APPROVED! Thanks, Ahmad H. and Thornton & Grooms. I was a former Burton & Sons customer for several years and was always pleased with their service. I can now say I look forward to being a satisfied customer of Thornton & Grooms."
