To improve efficiency, replace the humidifier pad, filter or element every year. Washing machine Check the water hoses. A small blister in the hose indicates wear and could cause the hose to rupture.
Manufacturers recommend replacing the hoses every five years.
Dryer Clean the lint filter after each load. Your dryer vent pipe should be made of rigid aluminum. The white vinyl duct that was common several years ago no longer meets most building codes. The coils need to be cleaned at least once a year. The coils may look like a grate or a wide radiator.
