Completed replacement of a gas furnace and AC. Disconnected and removed the old furnace and set the new furnace on blocks in its place. Reconnected the gas, electric, pvc venting and ductwork. Ran new drain hose for the furnace and AC coil drains and terminated it at the floor drain opening. Installed a T6 WiFi thermostat and connected it to the furnace. Recovered the old refrigerant from AC system then disconnected and removed the condenser and coil. Flushed the existing lineset and then reconnected it to the new condenser and coil. Pressure tested the lineset with 345 psi nitrogen to test for leaks. I left the nitrogen in lines until we return in the spring to do the complete AC start up procedure.
