I'm a happy customer of Wolverine Heating & Cooling. They installed a new air conditioner and heating unit in my crawlspace. Dave installed it in a good looking way in a tricky space. He did a very good job. It looks very professional and expert. I often choose bids that have the lowest price and end up regretting those decisions. This time, I chose Wolverine Heating & Cooling not based on price but based on their professionalism. So I paid a little bit more but it was well worth it. I got an honest installation at a fair price. it hasn't been cold enough to use the heat yet but I'm confident the new energy-efficient system will work as well as if not better than my thirty-year-old system did. In the meantime, I am enjoying the air conditioning!
