Fantastic company! Mike came out gave an estimate no fluff which is what I like. He was honest and professional. The team that installed the unit worked well together and the work performed was stellar!! I highly recommend this company. If you want a great system from a company that has a lot of integrity give Great Dane a call and you won’t regret it!

Just had Great Dane install a new A/C in my home. Working with Mike and DJ was a great experience. Mike came to my home saw what I had and I told him what I wanted installed. There was absolutely no sales pressure and the price was perfect. The removal of old equipment and installation went very well. I’ve lived in my home for almost 30 years and had two A/C units prior to this one and neither worked like the one Great Dane installed. This company stands by their work and does an excellent job.

Best hvac service in Jacksonville. When you call you get in touch with the owner Mike. He respects your situation and needs. He treated my time as Valuable as his and immediately sent out a technician to solve my problem. Most places make you wait all day. The efficiency and quality of work is second to none.

Huge thanks to the man (I didn't get his name) with the full beard and cool hat for helping us rescue a kitten from under a car in a parking lot on 5/12/2025

My experience with Great Dane was beyond my expctations. They did an amazing job in replacing my antique air conditioner! Mike gave me a great quote and DJ and his son completed this challenging job amazingly well! If you have any a/c problems I highly recommend hiring this company. They will not disappoint!

I just had a new a/c installed by Great Dane, they did a great job, very nice ppl, Mike was very nice and communication with him was great, which is very hard to come by nowadays and his employees were also nice and respectful and cleaned up well. And of course made sure my new unit was all setup correctly and working well before they left. I would definitely recommend them to friends and family and will call them again if and when I have an issue again.
