Our Experience with Great Dane was outstanding. Our A/C went down the team showed up Monday morning first thing. We had cool air flowing in no time. The crew was fast, clean, and finished under time. June in Florida can be really tough and Great Dane stepped up bigtime!! Everytime we have needed them, they show up! The new thermostat has current technology too!

I am forever grateful to have been connected with Great Dane Heating and Air. I'd been without A/C for quite some time. It was so amazing; the care and concern that Mike (and MJ & Brandon) had about my situation. I know I chose the right company. Now my home has an amazing (brand new) system. Not only was Mike professional and knowledgeable, but he wanted to make sure that everything was as it should be. These days and times, customer service is not what it used to be. But I recommend Great Dane any day, anytime, to anyone who wants top notch service, reasonable prices, and to be connected with one of the best companies, run by one of the best persons in the business. THANK YOU GREAT DANE!!

What an amazing experience! Mike and the team were very professional, friendly, and knowledgeable. The price was not unreasonable. So happy we found this company. We know we will be taken care of in the years to come. Great people! Great company! Wanted to update review! On October 29,2025 I notice my AC unit was not working. I called Mike, he answered immediately and within two hours a technician was at my home and the unit was repaired. That is the definition of GREAT service. If you need a company that cares about their customers not to mention the pricing is awesome make the call. You want be disappointed!!!
