When the warm summer months arrive, it’s time to prepare your Goodman furnace for a season of rest. Shutting down your furnace properly ensures its longevity and optimal performance when the cold weather returns. The process of shutting down a Goodman furnace is relatively straightforward, and by following these simple steps, you can ensure that your furnace will be ready to keep your home warm and comfortable during the next heating season.
Before beginning the shutdown process, ensure that the furnace is turned off and has had ample time to cool down. Turn off the gas supply to the furnace and disconnect the electrical power. Once the furnace is isolated from its energy sources, you can proceed with the shutdown. First, remove the access panel to the furnace’s blower compartment.
