  1. Change the air filter regularly – this ensures that the furnace operates efficiently and prolongs its lifespan.
  2. Clean the furnace regularly – remove dust and debris from the furnace and its surroundings to prevent clogging and improve air flow.
  3. Schedule an annual tune-up – an HVAC professional can inspect the furnace, clean it, and make any necessary repairs.
  4. Keep the furnace clear of obstacles – make sure there is at least 12 inches of clearance around the furnace to ensure proper ventilation.
  5. Use a programmable thermostat – this allows you to set the temperature at different times of the day, saving energy and money.
  6. Insulate your ductwork – this helps to reduce energy loss and improve heating efficiency.
  7. Keep the furnace level – an unlevel furnace can cause a variety of problems, including reduced efficiency and increased wear and tear.
  8. Don’t cover the furnace – covering the furnace can cause a buildup of dangerous gases and can also lead to reduced efficiency.
  9. Keep the burners clean – if the burners become dirty, the furnace may not operate efficiently or effectively.
  10. Replace the flame sensor – if the flame sensor becomes dirty or damaged, it can cause the furnace to shut down.
