During the furnace inspection, I discovered duct leakage in the attic, which was causing the attic to overheat and melt ice down into the walls. Additionally, I identified a high-efficiency furnace in the attic, which was producing 6 to 8 gallons of water daily. This is unusual for a high-efficiency furnace, as they typically do not produce water. I sent an estimate to address these issues and ensure the system operates at the required 80% efficiency.
