            My AC stopped working and Cornett Heating & Cooling was able to have someone out the same day. Danny was able to get out to my house earlier than expected and had my system back up and running within 20 minutes. Thanks to Danny and the team at Cornett H&C, true professionals!

            As always: helpful, knowledge, and great to work with. The biggest thig is: you can count on them to be honest. They won't try to sell you a new unit if you don't need one yet. Oh, and the guy who came out to my house appreciates dogs, so bonus points for that.

            Our AC had an issue last night, we called this morning, and a tech was scheduled for 2:30 and arrived at 11:30! They did an amazing job and my family now has working AC on a hot summer day. Danny and the company are awesome!
