Excellent customer care for after hours emergency phone conversations. Scheduled next day appt. Technician Eric provided excellent, amazing.service. Thorough, considerate, took time to explain and demonstrate equipment issues, serviceability, and options. Felt unhurried, thorough, calm, and he enjoyed customer interactions. Also - he is an excellent teacher (he should be training others if he is not doing so right now).

I am satisfied overall with/Great Dane, however, the cleanup leaves a lot to be desired! I was just outside and found a piece of wiring, three screws (any of which could’ve ended up in my tires) a main shutoff fuse, various brackets and pieces of plastic that you could had been snipped from something much larger!! One man was sent out to do a two-man job, (the techs words, not mine) and therefore what should’ve been a quick fix took several hours!!Adding to my initial review….I have changed my review to probably one star!! I’ve had to call several times to get my total project done, which for the money I had to pay is completely unsatisfactory!!! My electric grouping had to be done by two different people and I was left with a hole in one of my walls, which yea, is being repaired now, as I type this this, but still, I had to call after three weeks of hearing nothing about it!! Final inspection is now scheduled and hopefully I won’t have anymore issues! But my original installation date was 4-7-25 and now 7-26-25, have not been completed!! Very disappointed and would recommend!!

Bryan Holifield was here this afternoon 7-14-25. He was here for maintenance on my new Heating, Cooling and Humidifier unit which was installed last July 2024. He was an excellent technician who explained everything to me. It is in perfect shape. Nothing needed to be done at this time. I've had Great Dane for over 25 years or more. This company has always gone out of their way to repair, replace, and do maintenance for my family. I would highly recommend Great Dane to everyone.

Dominic was here today to service my system. My unit is 21 years old. Dom was an excellent, knowledgeable, and caring technician for repairs, it was determined that I need to replace the whole unit. The repairs would be costly, plus my unit still was old. I still would need to get a new system in the near future.It was decided that it would be more cost efficient to just buy a new one now. He was fantastic, I'm very happy that I had Dom today. I am giving Dom 5 stars!

I am totally amazed and elated about our experience with this company. Robert and Rachel were wonderful at what they do. Our air conditioner stopped working, at a very inconvenient/hot and humid time. They met with us and in a few days we had a new air conditioner and furnace. The experience was excellent and we could not have hoped for anything better! Thank you for being so awesome! I highly recommend this company, 100%!!!!

Serviceman came to replace the water pump on the furnace. It had been leaking for a few days before I notice it. I was able to get a repair date in a few days. The repairman Brad was prompt, courteous, wore protective shoe coverings and did his work thoroughly and described the needed repairs with an estimate before starting his work. Great Dane is always professional and reasonable in their work. I definitely will use them again.

We had our AC and furnace replaced yesterday by Great Dane, and the entire experience—from the initial quote to the final installation—was excellent. Highly recommend them if you're in the market for a new system.On installation day, they text you an ETA along with a photo of the technician coming to your home, which added a great touch of professionalism and peace of mind. Our sales rep, Nick, was fantastic—very knowledgeable and never pushy. He took the time to explain our options without trying to oversell us.Overall, a smooth and professional experience!

Our appointment was scheduled between 3 PM.and 6 PM. The service tech, Kyle arrived a few minutes after 3. (We really appreciate Great Dane's timeliness.) Kyle was thorough, and restored our AC promptly. He then thoroughly checked all components to insure we wouldn't have contining issues. Kyle also gave me a tip on how to reset the system if the same problem were to recur. I know I have said this before, but Great Dane lives up to the "great" in its name.

Best contractor experience of my life.

I was confident of the thoroughness and quality of the work that would be done (no short cuts). And I am reassured that I have the support of a company that values me as a customer long into the future.An incredible group of people all working hard to provide the best experience for their customers. Thank you to everyone at Great Dane, you're amazing.

I definitely give Great Dane 5 stars for quality, service, professionalism and affordability. I'm not sure what these other reviews are talking about!! We've had other heating & cooling companies out to our house and they were a motley crew! Not to mention they didn't know what they were talking about. First, we had an issue with our carbon monoxide detector going off in the middle of the night. Great Dane sent someone out to the house within an hour of me calling. They advised that the furnace had a crack that could be causing small amounts of carbon monoxide to leak [after performing several tests and explaining everything to us]. In order to keep my kids and family safe, we needed a new furnace. I would hate to think that another company would sell me used parts and hope for the best. The furnace was old and needed replacing anyways. We got several quotes-- for the price and quality of the furnace, Great Dane was the best. A furnace is an investment, so I'd rather get a little better unit that will last me longer than have to do this again in a few years.The guys that came out were very personable, but more importantly- they were professional. I had a lot of questions- I'm pretty clueless about this stuff and my husband was at work. They went over every part of the furnace that I would understand and showed me how to program my new thermostat. I thought they went over and beyond the call of duty. Then, when I had a question about my humidifier when winter came, they sent someone to my house the same day instead of trying to explain it over the phone. I will use Great Dane again and will recommend to my friends.

I had some concerns with the performance of my air condition unit & what it was going to cost me to repair it seeing as it was less than 2 years old & was purchased & installed by Great Dane Heating & Cooling. After speaking with the owner (Josh) & having service calls (technicians Conner & Clayton), I am very pleased to say that my air has been repaired & to my extreme satisfaction. The owner & the technicians were very pleasant to deal with & demonstrated an ambition to get the job done as quickly as possible & done right. This company is extremely reputable & I would recommend them to anyone who wants exemplary service & satisfaction in quality & workmanship.

Had air conditioning looked at because the house temperature would rise throughout the day with air on. They came out, monkeyed around with the air conditioner for 30 minutes, charged me over 700 dollars. Next day, house temperature is still going up throughout the day. Texted them through their website, got no response. Waste of money and terrible business.

I have the DTE appliance protection plan, and my air conditioning was not working. DTE sent a service person from Great Dane, and he corrected the problem with my air-conditioning. I hesitated to do this Google review because I feel that the service man did a fine job, and he was a very kind, personable man. However, he did somethiing that disappointed me greatly. He told me that “for an upfront cost of $150” He could put a surge protector on my air conditioning unit. He also said he had a $50 discount coupon that he could apply. I told him to go ahead and do it. Then we began discussing a surge protector on my furnace, and I told him to go ahead and put one on that, also. In my mind, I was thinking the total cost would end up being somewhere around $250 plus tax (because I didn’t know if he would apply the $50 discount to the furnace as well as the A/C). In hindsight, I should have asked him specifically how much the total would be, but I trusted him when he said “an upfront cost of $150 and a $50 discount coupon”. When he was finished, he very nonchalantly told me that the total was $619.90. Obviously, it was a sales tactic to not mention anything about any additional costs. I did pay him because the work was done. However, I was very disappointed, and I felt rather foolish for making an assumption and not asking more questions. Unfortunately, Great Dane will not get my business from now on. If I call DTE to have anything fixed, I will specifically tell them not to send this company to my home. I learned a lesson, which is to be more specific and get a written quote on any work to be done in the future. Great Dane got a sale from me, but the sale had no repeat value. They did not earn my trust, and I cannot recommend this company to other potential customers.

UPDATE: After some conversation, Great Dane provided a refund for the incomplete repair.ORIGINAL: At this point, I have to leave a one-star review. My AC stopped working on a Monday, and the company was able to send a technician out on Thursday. I paid a $130 diagnostic fee and was told the issue was a small leak that could be resolved with EZ Seal. After I approved and paid nearly $800 for the repair, the technician then told me he had accidentally spilled half the EZ Seal and would return later that day to finish the job. He was friendly and professional during the visit, but unfortunately, he never came back.By Sunday, the AC had stopped working again — less than three days later. It’s 100° outside, and I have children and pets in the house. The repair clearly didn’t hold, and I never received the full service I paid for. The diagnostic fee now feels meaningless. At this point, I believe I should be refunded for the incomplete sealant application, the refrigerant that leaked out, and the membership plan I was sold, as I no longer have confidence in this company’s service or accountability.

We were astounded and grateful! After our inital plea was made on the hottest day of the year for A/C. A service technician, Mihali, arrived only two hours later. It took him only an hour to diagnose and repair. The A/C has been working better than ever. The service technician and receptionist were personable, efficient and proficient. We highly recomment Great Dane.
“Service today from Great Dane HVAC was the best experience we have had with any HVAC company.

“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.”

Thank you Great Dane!”
