Josh was prompt at returning a text and putting me in touch with Julie to schedule a service call. Danny was on time, let me know everything before he did it and how much it was going to cost. No hidden fees. Very personable and knowledgeable. I highly recommend Cornett Heating and Air.

Cornett was extremely responsive and had somebody out within hours on a hot day to replace a capacitor and get the house cool again. Very professional and takes the time to explain what they're doing and why.
