“I would like to commend Mr. Kelly from Duggen’s one hour heating and air conditioning for providing truly outstanding service. From start to finish, he demonstrated professionalism, thoroughness, and genuine care. Before beginning the service, Mr. Kelly took the time to clearly explain each step he planned to take, ensuring I understood what to expect. Throughout the process, he kept me informed of his findings and made sure I was comfortable with the work being done. After servicing both HVAC units, Mr. Kelly went a step further to verify that the indoor temperature align accurately with the reading on his diagnostic device, showing his attention to detail and commitment to quality. This is the second time Mr. Kelly has served our unit, and once again, it was exceptional. Thank you, Mr. Kelly, for your professionalism and dedication. Your service it is truly top-notch! -Mark”

“I cannot say enough good things about Calvin Jones. Calvin is special. He is first and foremost a superb and capable heater and air expert. He is courteous, smart, and efficient in his craft. He is quick to find a problem, and he is extremely professional as he goes about the business of repairing the problems he finds. He explains things extremely well, he does top quality work, and he cleans up after his repairs. We enjoy his company, and we are not going to be very receptive if and when the Duggan's front office tries to send anyone other than Calvin to our home in the future. I consider Calvin the "best of the best" and he should be treated as such by his leadership. Thank you, Cal.”

“Spencer is very knowledgeable and even better at explaining how AC systems work. He's been here before but even with it being years ago, was able to rapidly diagnose and fix the issue with my HVAC. Highly recommend Duggan's, they fixed my incorrectly designed system and it's kept on trucking for years, whereas before I had to have other services out multiple times a year to "fix" it.”
