Completed gas furnace replacement. Disconnected old furnace and removed from house. Set new furnace on blocks and reconnected the gas, electric, pvc venting and ductwork. Installed a new T6 WiFi thermostat and connected it to the furnace. Disconnected the other two thermostats per owner request and bypassed the existing zone control board. Ran new drain hose for the furnace and AC drains. Run tested furnace but will still need a technician start up. Thank you for choosing Black-Haak Heating.
