Completed gas furnace and AC replacement. Disconnected old equipment and removed. Set new furnace on blocks and reconnected the gas, electric, pvc venting and ductwork. Installed a new AC coil in the plenum. Set the new AC on a new pad and reconnected the refrigerant lines. Pressurized the lines with approximately 520 psi nitrogen to test for leaks and to keep any moisture from collecting until we come back in spring to finish the start up. Run tested the furnace but our office will contact you to schedule a time for a service technician to come do a complete start up procedure on the furnace.
