Wolverine Heating & Cooling came out a few days ago and got my furnace running for me. They are very friendly people, and they are very hard workers. What I like about them most is how quickly they come out when I need them. That is very comforting. Whenever I call them, they tell me they will be right here, and that if they don't make it, their backup will. You don't have to wait around on them, and I am so glad. Because sometimes it is very cold here and I really need them in a hurry.
