Was able to get on the schedule next day, tech was quick to diagnose the problem and took the remaining time to inspect the rest of the system and do preventative maintenance.

Arrived on time. Very professional. Took the time to explain the process involved with replacing the furnace/AC system. Once the work was completed maintenance of the system was explained to me. The old system was removed and the work area was cleaned. Very impressed with the quality of the work that was performed. I highly recommend this company.

First time to use Cornett. Found them through a personal referral. The techs were very clean, polite and informative. They fixed my problem per my request and recommend new unit which I agree we need and will do in the spring with them.
