Completed gas furnace and AC replacement. Disconnected and removed the old furnace and set the new furnace back on blocks. Reconnected the gas, electric, pvc vent pipes and ductwork. Ran new drain hose for the furnace, AC and humidifier drains. Recovered the old refrigerant and disconnected the old condenser outside as well as removed the evaporator coil from inside. Flushed the lineset and reconnected it to the coil and condenser. Pressurized the lineset with approximately 400 psi nitrogen to test for leaks. We will return in spring to complete the AC start up procedure when it is warmer. We run tested the furnace but our office will contact you to schedule a technician start up at your convenience.
