Furnace precision tune up; clean and tune up furnace; clean burners, test ignition components, adjust gas level, test safety circuit, check indoor motors, checked all electrical components, tested indoor air flow, checked heating temperatures, and tested overall furnace operation. Found inducer motor pulling more power than manufacture label states. This is an early sign of failure, along with grind sound when motor starts. Do recommend furnace replacement over large repair as this. Blower wheel is dirty and should be pulled and cleaned if furnace isn’t replaced. Due to age and current condition, replacement is encouraged.
