Customer Testimonials

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!

Danny always does such a great job. He found a small issue on our outdoor equipment during our seasonal maintenance, explained what was wrong and how much it was to fix, and then promptly made the repair. It provides peace of mind knowing that the maintenance plan worked the way it is supposed to and that my A/C is ready to handle the heat of summer!
