We have been using Wolverine Heating & Cooling for years and we have always been very pleased with them! Their technicians are always prompt, friendly, courteous and respectful of our home. If there are any problems they take time to explain what is going on and they go over options to try to salvage what we can to wait a bit to replace things. They also take time to answer our questions. This last time they came out for our winter annual inspection and put a filter into the humidifier. He even showed up early. I would tell potential customers to call them, you won't be disappointed. We will continue using Wolverine Heating & Cooling!
