Completed gas furnace replacement. Disconnected and removed the old furnace and set the new furnace on blocks in its place. Reconnected the gas, electric and the ductwork. Removed existing 1 1/2†pvc vent pipes and installed new 2†pipes to be sized properly for the new furnace. Installed a new T4 thermostat and wired it to the furnace. Ran new drain hose for the furnace, AC and humidifier drains. Run tested the furnace but our office will contact you to schedule a technician start up at your convenience.
