HVAC reviews in Clinton Township, Michigan

Adam arrived to work on a chronic furnace issue. Three other companies have tried to repair it over the last year, with no solution. Adam arrived and immediately told me with cautious confidence that he would be able to fix it. Polite and professional, he told me that he trained on my furnace design. Within minutes of looking at my system, he knew EXACTLY what was the issue... ordered parts, and two days later was installing them.... The system is working like new. Future needs will be handled by Finzel's permanently. THANK YOU!

I would recommend Finzel’s Heating and Cooling for your HVAC needs. Adam initially came out and stated that the blower motor needed to be replaced. During install, Nels noticed that there were issues with the heat exchanger and the system would need to be replaced sooner than later. Two weeks later, the team installed my entire system within a matter of 6 hours on one of the coldest days of January 2026. Nels, Jayson, and Alex were great at getting all the work done in a timely matter and answered all my questions during the install. Great job guys!!!

Alex and Caiden were top-tier professional from start to finish. Upon arrival, they introduced themselves with friendly faces. They were helpful too, answering questions we had about the humidifier. They walked us through the parts of the system and how to maintain it. To be honest, they are the reason why I am signing up for a maintenance plan and would ask the schedulers that they be the ones to service the AC and furnace in the future. That is just how comfortable we have been working with them. Christy has also been a great help since the first time I reached out with questions about Finzel’s work on the home I recently purchased. I am thrilled to have “inherited” a great hearing/cooling company to work with. Thank you all so much!

Great Dane Heating and Cooling has been our go to for all our HVAC needs and service. We subscribe to Great Dane care plan which always gives priority to their great service. Had our yearly furnace maintenance, it was a new Tech Jim for us but usual awesome Great Dane service. We got a great discount on furnace filters during the yearly open house.

They came out on a Thursday for a tune up and inspection on my boiler system, when he left he did not turn on my power to the system, when I went to turn it on I smelled gas, they missed the gas leak, I called them on Friday morning to set up an appointment for Saturday and they would not do it, after some time they decided to send someone out, he found the leak and did nothing, it took several days for someone to get back to me, they wanted to charge me almost $500.00 to fix, they were charging me for several things I did not need, three weeks later I had enough of them so I finally had someone else to come out and fix it, only charge me $125.00
Will NEVER use them again.
To update your response to me I personally replaced the thermal coupling two weeks before your technician came out. He forgot to turn the power on my heater. That’s why I went downstairs and that’s when I smelled the gas. It was your guys that missed it.

I had my furnace cleaned and evaluated. The 2 techs that came arrived on time, were very considerate and explained everything. My furnace was installed 20 some years ago and going strong. Thank you Great Lakes Cooling and Heating. See you in the spring for the air conditioning unit.

We have an older furnace (25 yrs old at least). I can’t stress enough how the membership and maintenance appointments helps. We’ve had a couple repairs in the last five years but way cheaper than purchasing a new unit. Great Dane technicians are always so thorough and helpful. I appreciate the detailed reports. Highly recommend!

Great service and very professional. Connor Thank you for getting my heat working again. Derek solved my plumbing issue. I highly recommend Great Dane

Had no water flow to my whole house humidifier. Called Great Dane and Nick came out and found the problem. He also gave me several hints about HVAC maintenance. He was both friendly and efficient. Great experience, great results.

So we had Shad come out to our home to do a panel upgrade. This kid was the most professional and knowledgeable electrician I've ever seen. Dummied it down so we could understand what the job entailed. Very professional. Sad I can only give him 5 stars.

We requested a technician due to an issue with inconsistent heating and cooling in a few rooms throughout our home. We have a >25 year old furnace so we knew a recommendation for a new system was likely. I specifically asked for someone to assess our ducts, in addition to the furnace. They were able to schedule a technician to come out within a few days.

The technician spent about an hour looking at the furnace and taking measurements. He didn't show us any pictures, but he said he used a camera. After the inspection, his conclusion was that we needed a new furnace. He said he could potentially get someone out for a quote that afternoon.

The shocking part was that he told us: "one heat exchanger tube has a hole." We asked if that was dangerous/urgent because of the risk of carbon monoxide. He said it was not and that we'd be ok. He knew we had a small child in the house. He left the furnace running and scheduled us with the salesman for a quote that afternoon.

We went on to get additional quotes for a new system. Later that week, I called Great Dane because we spent $130 for them to tell us verbally that we needed a new furnace. We already knew that. I was disappointed he said there was nothing we could do with the ducts and didn't give us any documentation. I requested the report from the tech. They sent me the report later Friday. That evening I read the report and it said:

"WARNING we have found an unsafe condition in your appliance that may be dangerous until repaired. We have left the gas supply and the power switch to the appliance in the off position. Our Technician will document the actual condition and take pictures to share if available. Your Technician will also review all options available and provide a quote to repair or remedy the issues found. ** Unit is UNSAFE for OPERATION **"

I read this report four days later after being told verbally that we were safe. The furnace had been running the entire week. It was very stressful to find this out on Friday night and not know which to believe - what he told us in-person or what he wrote in his report.

We ended up getting five total quotes for a new system. Another company came in to quote and the gentleman identified a pretty basic issue with our main supply line. It was a $50 fix. So there was an issue with ducting, but the Great Dane tech missed it.

The quote from the salesman was pretty high. He only offered us two top-of-the-line options. He didn't ask whether we wanted a mid-grade or lower option. We received five total quotes and Great Dane's was the second most expensive.

Based on the bad experience with the tech and the salesman, I cannot recommend this company. I cannot come up with any positive reason why the tech would tell us verbally that there's a small leak, but we're safe, and leave the gas and furnace on. Then, write the complete opposite in his report.

They guys did a great job fixing my electrical but after they left I realized my furnace wasn’t working. I called the office and was told that to have the guys come back to find out why it wasn’t working I would be charged again after hours call or a HVAC service call! And asked if I could wait until the next day- with no heat in 20 degree weather! I discovered they had just forgotten to turn the furnace switch on. So all is well but not happy that they wanted me to pay for something that was their doing.

Service rep arrived on time was very cordial and ran all diagnostics in a timely manner. He explained what he was doing and readily answered all questions. He quickly sent a document with his findings and identified all services to consider. Price covered by DTE

Service was amazing, we had the technician Columbus at our house two times and he is a great guy!! He got the job done fast and efficiently and was an overall amazing technician. Thank you!

I had a great experience with this company. I had a fuse that kept blowing after getting a hot water tank installed. They fixed it and also got 2 outlets working that were not. Up front and reasonable with pricing. Also suggested to fix a few loose wall switches and sockets. Ended up getting a new outlet for tankless water heater so it would not be on an extension cord. Full service! Highly recommend!

Absolutely do NOT use Great Dane. In my experience, they show up completely unprepared, charge outrageous prices, and STILL fail to fix issues. They came out to our home and our business multiple times within just a few weeks, for the same issues, billed us, and problems remain unresolved. It felt like they were just guessing and collecting payment.

Based on what I saw, the technicians seemed like they had no real understanding of what they were doing. I’m extremely frustrated and disappointed, and I strongly recommend choosing literally ANY other company. My experience with them has been nothing but incompetence, excuses, and charges for zero results. They lack any customer service skills.

Excellent service. Technician went above and beyond to ensure fair price.
Repair performed flawlessly. Technician was professional, respectful and explained all service in detail.
Enjoy some conversation and a couple laugh. Couldn't have been a better experience.

Great Dane came out and gave me their honest opinion about which unit to go with, rather than try and sell me the top of the line unit. Price was comparable to other companies. Purchasing and financing was an easy process that took less than 10 minutes.
Installation was excellent. Jacob and his partner arrived on schedule and got to work right away. After installation he walked through the areas with me, which were clean of debris and all hoses and electrical were installed aesthetically pleasing, and answered any questions I had.

Clayton was great. After being ghosted by a different company I called Great Dane and they came out next day. I had an unusual issue with my hot water heater and he did not leave until he had it figured out. Highly recommend.

Johnathan was outstanding! He explained exactly what he needed to do and why took great care to make sure all my questions were answered to my satisfaction.
The installation crew (Nick & Lance) were absolutely the best! When they finished the install Nick explained everything to me and answered all my questions. Will definitely recommend Great Dane to friends and family.

Last night our hot water tank died. They had someone out to my house the next morning. Very respectful and cleaned up after themselves. Would highly recommend this company.
