We’ve always had Great Dane’s service since putting in the system around 2006. We use the annual maintenance plan to do the updating and cleaning of the system. The technicians are always friendly, respectful, and well trained. They always tolerate our poodle and previous dogs well, and most have dogs of their own. (Love this about them! Our system has aged really well with their great care. Today’s service was no different. The technician was great, and helped resolve a very small problem (connecting to Wi-Fi) quickly and knowledgeably. 5 thumbs up, stars, or whatever. I will go back to them for HVAC every time.

Great experience with Great Dane & Nick the technician assigned to my call. Nick was early to my appointment, was professional and explained everything in detail. Got my A/C back up and running. I have the DTE appliance service contract and Great Dane was who they hooked me up with. No issues!

Adam was great knowledgeable, friendly the only thing I am not happy about is when I purchased the maintenance plan I thought that I would get a furnace tune up now I was told that the gas company checkup was my furnace visit. If I had known that I would have waited

I hired Great Dane Heating & AC for a furnace inspection which was completed October 7, 2019. Joel, the manager texted me the name of the tech along with picture of him, which I thought was a great practice.Kristofer, was the technician that came out to complete the job. He was exceptionally upbeat, friendly & knowledgable and explained every aspect of the inspection. He struck me as being trustworthy as well, which I highly value. I highly recommend this company, especially Kristofer!

Called Great Dane because one of our hot water tanks wasn’t giving us hot water. Luckily, it didn’t completely break on us and leak water, but we had to replace it. They were out quick, Nick was great. They were very clean and conscious of our hard wood floors. Covid safe as well. Very pleased!! Customer service is wonderful there, would HIGHLY recommend them!

They responded to my request quickly and sent Jeremy within the hour. He was very nice and knowledgeable. He gave me such great information and solved my issue quickly. Such a lifesaver!!! I’m new to the area but I’ll definitely be using Great Dane as my go-to company from now on.


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.
