Duke's recently installed a new HVAC system in our Palm City home. Don, the sales rep, was pleasant and thorough with the free estimate. He provided options that worked well with our budget and had the job scheduled within a week. Everything went smoothly with the installation and we are very pleased with the results. 👍

Rob is the only one that I would use
Rob is the only one that I would use. He is knowledgeable and extremely helpful. I have had so many problems with my unit installed from another company till Rob started my service.
Pamela Shore
The whole experience exceeded expectations.
I’m so impressed with this company and their entire team! From the very start, Don was incredibly responsive, professional, and detail-oriented in coordinating everything and making sure the job went smoothly. And Matt—truly exceptional. He went above and beyond not only with the AC replacement but also by taking extra time to organize and improve our attic space. He made it safer, cleaner, and more functional than it’s ever been. That kind of care and pride in workmanship is rare these days, and it really stood out. The whole experience exceeded expectations from start to finish. I’ll be recommending them to everyone I know. My recommendations don’t come lightly!
NAS Reed
