Neil and his team from Superior were great to deal with. They came same-day and the new furnace took only @ 2 hours to fully install.He was extremely thorough and gave me things to expect and look for with anew furnace and to call them if I had any concerns or questions.Also walked me through the functions of my new Smart-thermostat which is wonderful.RobG, Cambridge ON
