            We relied on Cornett to replace our furnace last year and their service and work were outstanding and at a fair price. More recently, the Cornett team rerouted a number of air ducts in our old house as part of our kitchen remodel. And again, the work was very well done - and the team was able to complete the work quickly. I m glad a neighbor recommended Cornett. We’re very happy to work with them!

            Cornett is top notch. Knowledgeable, honest, and dependable. I highly recommend them. You’ll be in good hands. We had an issue with our AC sweating. We had another company come in who were not helpful. Cornett came in and helped us properly diagnose the problem.
