Douglas Mechanical Services Heating and Cooling Flint

Mark is GREAT! He was one of only a few contractors in the area who answered on my first call and one of two who came to my house to give me a quote (most quoted over the phone). He was friendly and professional. His quote was the best and I only had to wait a few days before he started working. He installed air conditioning for me but had to take apart my entire system to do it. I was very impressed with how fast and efficient he was. Everything works great now and he backed it with a warranty. Can't wait to enjoy fresh cool air this summer. Thanks Mark!

Mark did a great job hooking up my A/C unit. He showed up when he said he would and completed the install in a timely manor. Mark was professional explaining what is being done and even gave me a few pointers on my HVAC system. Thanks for the work!

I could not be happier with this company! Mark is fantastic! So helpful, kind, and professional. Thanks. I will see you soon for new a/c and furnace!

Excellent
