• Change your furnace filters regularly. You can save up to 40 percent in furnace electricity costs just by changing your furnace filter. A clean filter ensures efficient airflow while maintaining the air quality and comfort of your home. A clogged air filter will only make your furnace work that much harder to keep your home warm.
  • Set your furnace fan to “auto.” Setting the fan switch on your thermostat to “on” will cause it to run all the time, whether or not your home needs heating or cooling. Switching from continuous to auto can save from about $75 to over $400 per year.
  • Fireplaces look and feel cozy, but can be expensive to use. We all love the warm glow of a fireplace but keep in mind that this entertainment feature comes with a price tag. Both gas and wood fireplaces are typically less efficient than the average furnace and won’t heat an entire home, so that cost is being added to your regular heating bills. Fireplaces might add a little extra comfort to a room, but generally shouldn’t be used in place of your furnace
  • If your home has a fireplace, close the chimney damper when not in use to stop cold air from entering the house through the chimney. If you never use your fireplace, consider having a contractor plug and seal the flue to reduce heat loss through the roof
  • If your furnace is more than 15 years old, it could be wasting energy and money. When shopping for a new furnace, look for an ENERGY STAR certified model with an annual fuel utilization efficiency (AFUE) of at least 90 percent. To save electricity, choose a multi-stage furnace with a variable speed fan motor (also known as an ECM, or electronically commutated motor). These furnaces use less electricity and are quieter than those that use standard fan motors. Depending on how you use your fan, you could save $80 to $380 a year in electricity costs.
  • Just like a car, your home heating and cooling system needs regular maintenance to keep it running efficiently. That’s why it is smart to hire a qualified technician to service your furnace and central air conditioner annually. The technician should check indoor and outdoor coils, airflow, refrigerant charge, and electrical connections.
