Was completely thoroughly impressed. I had friends staying at my home in Prudenville on Christmas Eve and my furnace would not work. I actually called another company that completely ignored my call and never called me back. I called Mueller Mechanical and within five minutes Andrew the owner said he will be at my home in 45 minutes. He had my furnace up and running within five minutes at a very reasonable price. I will continually use him for anything mechanically related for my home in the Houghton Lake, Prudenville, Roscommon area. His professionalism as well as seeing the necessity to make sure my friends were warm especially on a holiday evening goes far above any cost. Thank you, Andrew for taking care of my friends. You’ve won a fan for life.

Andrew showed up at my house on the same day I called him. He worked on my furnace and was done after an hour. Great communication and professionalism.
