Nick
After calling 3 different HVAC companies who couldn't get to us until 24hrs later, Danny with Cornett was able to get to us in 10 minutes. He made sure we understood the process from start to finish, and was extremely nice and respectful. I wasn't brand loyal on HVAC until today. I will 100% be using Cornett for all of my heating/cooling from now on.

First time using Cornett Heating and Cooling and couldn’t be happier we chose them. The office staff that answered my call was friendly and helpful and sent a technician out within a couple hours. Our technician, Zach, was amazing! He was friendly, honest, and explained everything he was doing. Added bonus-he was able to fix our HVAC system on the spot. We will definitely be returning customers and recommend them to all our family, friends, and neighbors.
