Arrived on site at Oak Ridge Presbyterian Church to install a new Coleman furnace. Prior to equipment removal, all necessary safety precautions were taken, including disconnecting electrical power to ensure a safe working environment. New Romex and BX wiring were installed to supply power to the furnace. All electrical connections were properly secured using approved connectors to prevent wire fatigue or breakage. Electrical testing confirmed that all circuits were wired successfully and operating as intended. Sheet metal transitions were fabricated and installed to ensure proper airflow and a secure fit between the new furnace and existing ductwork.
