I am a highly skilled and experienced home service professional. I recently completed a job replacing a humidifier pad and inspecting a furnace. The humidifier pad was old and worn out, and it was causing the furnace to run inefficiently. I replaced the pad with a new one and tested the furnace to ensure it was running properly. I also inspected the furnace for any signs of damage or wear and tear. I found no issues, and the furnace is now running smoothly and efficiently.
