Customer Reviews

Ted Schoenleber — review for Cornett Heating & Cooling

5/5
We had an HVAC condensate pump that leaked after a power outage causing all sorts of water damage but we were unsure what caused it. Zach was an amazing technician who diagnosed our entire system, trouble shot the issue, and was able to determine the pump wiring was inaccurate which led to the failure. He fixed the pump, demonstrated it's renewed function, and never once made us feel rushed or concerned. Outstanding service and great pricing, I would highly recommend them.

5/5
Cornett was great to work with, from the technician to the office staff. Technician Zach was friendly and provided a thorough diagnosis of our older AC that had quit running. We received a detailed explanation of the issue with repair options. He was able to fix the system and did not push any unnecessary upsells. Honest, local company worthy of their high recommendations.
