My furnace went out during the beginning of the COVID crisis. Great Dane came out and fixed the problem with all safety standards in place. My furnace and water heater were both over 20 years old and I knew it was time to replace them. I called Great Dane. They sent their representative out right away. He answered all my questions and even steered me toward the most economical appliances for my home. I got a great price and help with financing on the spot. On the day of installation I was prepared for a stressful day. Instead I was at ease. They knew what they were doing. They notified me when the water needed to be shut off. They also fixed several issues related to the previous furnace. Everything was brought up to code. There work was clean and efficient. I am very happy with Great Dane.

Nick installed a new Bryant Evolution CONNEX thermostat. After he left, I looked in the box to review the instruction booklet and discovered the package contained booklets for Carrier products. Called Great Dane and spoke with Jeremy the next business day He said he'd print out the Bryant booklet and mail it to me.

Our technician Nick was amazing. He was prompt and Great Dane kept us totally appraised of what time he would arrive by phone and text. I appreciate Nick’s honesty and that right away he didn’t try to sell us a new furnace. Nick said the heat exchanger is in excellent shape, he checked everything out thoroughly. He said nothing has cracks or anything. He tested the carbon monoxide and it was good and he said our furnace is in good condition. We were very happy and would definitely recommend Great Dane, in fact they came recommended to us! I feel that Great Dane is a trustworthy company and highly recommend them. The services provided were above and beyond what I expected. Thank you

Great Dane has been a great company to work with over the years. I had them completely replace my HVAC system 5 years. Their techs are very professional and knowledgeable, and are always on time. Jeremy Geisler was out just recently for a rare fault condition on my AC system. He worked through all the possible sources of the fault, until reducing it down to a circuit board, which turned out to be the problem. I couldn’t be happier with Great Danes overall service.

Gas Furnace Repair in Shelby Township, MI 48315

“Same day of the installation of my air conditioner. Furnace kept running on heat. Called customer service and the installers returned to check out the problem. Eventually it came down to having a serviceman to come out and evaluate the problem. Chris was very professional, polite and on point for diagnosing the problem. He arrived quickly and upon consent ordered the repair part. It arrived 4 days later and Chris came back to do the repair. Everything works great. The customer service rep, Amy, was great. She kept me in the loop on the arrival of the repair part and followed up in letting me know Chris was on his way. I highly recommend this company. If I could give 10 stars I would. Using this company you will not be disappointed.” – Steve S.
