“Mr. Calvin did a great and thorough job with the heat. We were frosty the snowman in our house even w/ plug -in heaters for (3) days. I knew it was freezing when the dog was shaking inside the house. Shiver me timbers, right? Right 👍.... So I knew what company to call and tech to request "Calvin Jones"!!!! A standing ovation type service💪🎊. Started feeling heat asap, thank the Lord😇. He also fixed our AC when it went out in thisbSouthern GA heat, and fixed that too during the summer. Very prompt, professional, kind and thorough as I mentioned before. 5 star performance 🌟 🌟🌟🌟🌟”

“From start to finish, the experience was amazing. I was needing a new HVAC unit as soon as possible, especially before the "snowstorm", called them to set up the appointment and the office manager came to my house the very next day. She was so amazing, knowledgeable and personable which I appreciated. She went over my options, which I like that she gave me options and a final price after a discount. The estimate was lower than another estimate I received from another local HVAC company. I had to get financing and that was also very seamless and fast, really 5 minutes or less. The technicians were out the next morning. They arrived on time, were very professional, knowledgeable and really an all-around pleasure. Will, one of the technicians made sure to keep me updated throughout the process and was a pleasure to work with. Tyree and Randel worked so hard, working in a very tight space in the attic. Will, Tyree and Randel were great! I'm so glad that I have heat and air now.”

“Calvin was amazing! He’s been to my place multiple times over the last several weeks to evaluate an intermittent heating problem. You’d think since he’s been here more than once, I’d be paying for multiple service calls, but you’d be wrong!! Only had to pay once! I’ll definitely be using their services again!”

“I purchased a maintenance contract from Duggan's 1-hour Heating & Air for the mini-split unit in my workshop to have it serviced twice annually. So far, I have had service technicians that appear to be very accomplished at their skill/trade/training, as well as friendly, courteous, and very professional. The most recent servicing (Jan '26) by their technician, Chance Mills, was no exception. He thoroughly serviced the mini-split and was on his way. I have had a completely positive with Duggan's HVAC service.”
