Calvin and Marcus were the best! They arrived on time and were very nice and professional. Everything was explained and they went out of their way do a temporary fix until our air conditioner part could be ordered and installed. It was going to be about five days before the part would arrive, but someone from Duggan drove to pick it up! Calvin contacted us immediately and came over to install it the next morning. The AC has been great since! We really appreciated their thoughtfulness and great service during this hot August!

Kevin provided outstanding HVAC service. Our unit had been running 8–10 hours a day and still couldn’t keep the house at the set temperature, often falling 7–9 degrees behind throughout the day. Kevin was polite, professional, and took the time to listen to every issue I described. He went straight to work, quickly identified the problems, made the corrections, and explained everything in a way that made perfect sense. The difference in our system’s performance is noticeable. Highly recommend his service.

Shumar provided our Bi-annual service maintenance review on our system inside and outside (and Attic). He was very friendly and professional completing every task with care and excellence. We highly recommend Duggan’s and we highly recommend Shumar! He also changed our two return filters and the thermostat battery.
Kevin was professional and courteous. Did a thorough investigation of my 27 y/o system and as I expected, compressor was dead. So he provided me with a fair written estimate. So next review will be on the installation team and how (hopefully) quick they get my system swapped out.

Calvin and his apprentice came out to see what was wrong with our downstairs ac unit. They found the issue relatively quickly and fixed everything in a timely manner. This is the second time we've had Calvin and both times he's been very nice, respectful of the house, and does great work.
