“Duncan's Heating and Air is amazing. My new HVAC system failed right at the beginning of the summer and after several outrageous estimates from various HVAC companies a friend referred me to Duncan's. They came to my home in a timely manner and gave me an estimate that was several hundreds of dollars below that of the other companies. They were quick to schedule the repair appointment and the tech was able to repair my unit within a few hours. I am so impressed with the kindness and professionalism of this company and I highly recommend them to anyone needing service for their HVAC system.”

“Andrew installed a split system ac unit for us. He was punctual and did nice work! (Felt bad for him, he continued working to get the job done, even in the rain). It was a seamless process from the schedule to job completion. We will definitely use Duncan’s Heating & Air for future needs!”
