David H. says, "I wanted to upgrade to a smart thermostat but didn’t know if I had the required power for that. These kind folks came by the house, verified that a quick electrical hook up could be made, helped with a suggested smart thermostat, and drove to the local Ace hardware store for the purchase. 30 minutes later I had the smart thermostat that I wanted! Very nice technician! I will be using them for my upcoming AC and Furnace cleaning this spring"See more

Kate Sanchez says, "I had a great experience with KC heating and cooling. Kenny was very professional and extremely knowledgeable. He diagnosed the issue with my furnace and explained the repair process in detail. I appreciated how transparent he was about pricing, and there were no surprise costs at the end. The repair was completed efficiently, and my system is running perfectly now. The whole process was stress-free, and I couldnt be happier with the service. Ill definitely be calling them for any future HVAC needs. Highly recommended!"See more

Martha J. says, "Dara was professional, knowledgeable, and truly an all-around great guy. He came out to service our furnace and did a thorough deep cleaning, and the entire experience was incredibly refreshing. We chose Dara because he only charged $49 to come out and diagnose the issue on a weekend, while other companies were quoting $200 or more just to show up. That alone set him apart. From the moment he arrived, Dara was honest and transparent. He took the time to walk us through every option, explained what was actually necessary, and never pressured us into making a decision. That level of integrity is rare, especially in the HVAC and furnace repair space. Not only did Dara fix the problem, but he also took the time to educate my husband on how our furnace works and how to better maintain it going forward. We learned a lot and felt completely confident in the work being done. We have already saved Dara’s information and plan to work with him again in the future for air duct cleaning and ongoing furnace maintenance. If you are looking for reliable, affordable, and trustworthy furnace service in Denver, I wholeheartedly recommend reaching out to Dara. Hands down one of the best furnace technicians in Denver."See more

Donald C. says, "Called Dan's Contracting because my furnace was not igniting. He scheduled the appt for the next morning, showed up on time, was respectful to cover shoes when on our new hardwood floors, and had the furnace up and running within the hour. He showed me how to do some simple maintenance, replace filter, clean dust area around ignitor, so that the chances of having problems again is reduced. Overall great experience, reasonable fees."See more
