Keep your furnace clean, lubricated and properly adjusted with annual maintenance. If your furnace is working at peak efficiency it will use less energy and cost less to operate.
Clean or replace the filter every 1-2 months – a dirty filter reduces the airflow and forces the furnace to run longer to heat your home.
Consider purchasing a new ENERGY STAR® qualified furnace with a variable speed motor. An average home can save up to $571 in natural gas and electrical costs annually when upgrading from a standard 60% efficiency natural gas furnace to a 95% efficiency furnace with a high efficiency variable speed motor.
