Best Control Panel in Charlotte NC

My technician, John, was professional and on time. He was very respectful of my home and always put cover slips on his boots when coming inside. He spent the majority of the day in the crawl space under the house in 40° weather, but every time he came inside to talk or give me an update he had a great disposition and positive attitude. The final solution was not an obvious one, but thanks to his logical, methodical approach and tenacity he was able to get the heat restored in my house by the end of the day. Additionally, Michael & Sons went the extra length and extended the labor warranty the previous home owner had on to me since the unit was less than 4 years old.. Excellent service. Will absolutely use again and recommend to anyone with HVAC or plumbing issues.
