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

We now have peace of mind to get all our heating/​cooling and plumbing needs met at an excellent value!!”

“We had a backed up drain in our basement and Thornton & Grooms sent a technician, Cody D. who was excellent!! He was both professional and knowledgeable. No high-pressure tactics, just the facts and resolved our issue promptly. This was our second experience with the company and Cody mentioned their Home Care Club which made sense to both my husband and I. We now have peace of mind to get all our heating/cooling and plumbing needs met at an excellent value!!”
