Customer Testimonials

Josh Cornett of Cornett Heating and Cooling is my GO TO for my home HVAC system repairs plus as a Realtor I recommend him highly to my clients - he’s on my preferred vendor list which says a lot as no one makes it to that list unless they’re tried and true. He’s saved me from costly fake repairs with his vast experience and honesty. Always fairly priced too. I wouldn’t trust anyone else.

General system check and routine maintenance service on (7/10/23). Fixed heat issue on 11/2/23. Always efficient service. Would not use any other company for any of my HVAC needs. Great repair work at a reasonable price.
