Our experience with Superior HVAC Service was excellent! Kurtis conducted a free inspection, answering all our questions with courtesy. He provided a better price than other quotes, and the installation of a new furnace and AC unit was completed in a day. The work looks great, and the equipment functions wonderfully. I highly recommend Superior HVAC Service
