Completed Gas Furnace replacement. Disconnected and removed old furnace and then set new one on blocks in its place. Reconnected the gas, electric, PVC vent pipes, and duct-work to new furnace. Run tested the furnace, but will still need a technician start up. The Office will follow up to schedule a technician to return to do the Furnace efficiency startup, which is required for warranty purposes. Thank you for choosing Black-Haak Heating.
