            Cornett replaced a 3-ton Trane that went bad with a 3-ton Bosch. They did a great job with installing, including reconnecting the zone system that already existed. They also explained all the rebates available, including Federal tax incentives. The Bosch seems to work well. The outdoor unit is very quiet compared to the Trane, and is much smaller.

            From initial call to install Cornett Heating and Cooling exceeded all expectations. Receptionists were forthright and efficient in timely scheduling(during busy 100 degree summer days) and the service team was meticulous with the installation. Highly recommend!
