“Kim and Kelly came on Monday, February 10, 2025, to clean my ducts and, they did a very nice job!! DunnHill was referred to me, as they did a great job for friends of mine and, I am very happy that I contacted them to have this process done. Kim and Kelly are very professional and hard-working women, with a great work ethic. The cost was in line with the average cost in my area and, this is their specialty. I am quite happy with the results and, I highly recommend Kim and Kelly.“

“Paul was on-time and ready to fix all the problems especially from the last two furnace companies could not fix. All issues were resolved and we found a new furnace company. Tempura Mechanical .“

“Awesome service! Called them on a Thursday afternoon and they had our AC fixed by noon the next day. Luckily it was just a repair and they did a great job. The techs that showed up explained what happened, what they replaced, and how to help maintain our unit. Fantastic price as well. Definitely recommend them if you’re in need of an AC or furnace fixed!“

“I had the pleasure of working with Steve and the team and Coleman Systems to have a vent duct installed in our new retail space for our laser. Steve came out and looked the place over, saw what our needs were, and even diagnosed an unknown issue with the HVAC system. They then worked with the roofing company for the space were in and coordinated an install time that met our even timeline. Work was top notch and done timely and professionally!“

“Brady was outstanding doing an analysis of what was needed for our house and getting everything scheduled. Even went the extra mile and made sure our AC survived until installation day. Logan and Zach did the install of everything and were very polite and professional. Everything looks and works great. Highly recommend.“
