            Bill Scullin - 160 Berrywood Drive , Severna Park, MD, US
            This company is great. Very professional and responsive. Just moved into a house with an old furnace. Danny took the time to educate me on my system and allowed me to shoulder-surf so I could learn a thing or two. Very respectful and hardworking crew. I signed up for a service contract on the spot. Highly recommend.

            Josh and his team did a great job putting in our Bosch heat pump last season. This year Danny came out to check on the units and was very helpful in explaining what they were doing. Highly recommend Cornett!

            Josh came to restore heat to our house soon after I called. It was a simple fix, so he didn't charge me! Amazing, as other companies charge $100 just to diagnose. He is also very knowledgeable. He is coming back this weekend to teach my husband how to troubleshoot (our very sensitive) heating unit. So happy to have found this company. Cornett Heating and Cooling definitely has a new customer for life!
