Increase home heating efficiency
Furnaces are responsible for nearly 30% of home energy use. Use these tips to increase efficiency and minimize energy costs.
Air filter
Clean air filters help furnaces run efficiently and reduce energy use. Check filters every 30 days, especially during cold winter months. If dirty, replace it if disposable, or clean it if permanent.
Savings: Up to 15% annually
Preseason tuneups
Schedule yearly HVAC system tuneups to improve furnace efficiency and life span, while maintaining comfort. Besides saving energy, tuneups can help avoid unsafe conditions, including fire and health hazards.
Savings: Up to 10% annually
Smart thermostat
Smart and programmable thermostats can save energy by reducing heat overnight or when away. Set thermostat to 68 F, then program an 8-degree decrease overnight or when away.
Savings: Up to $180 annually
Insulation
Add or upgrade insulation to save energy. A minimum insulating value of R-38 will reduce energy bills and improve comfort. Start with the attic, then consider exterior walls, crawl space or basement.
Savings: About $200 annually
Duct sealing and insulation
Seal and insulate HVAC ductwork to improve energy efficiency, especially seams and connections that run through an attic, crawl space, basement and/or garage. Check connections where vents meet floors, walls and ceilings. Also make sure air vents aren’t blocked by furniture or rugs. A contractor can inspect and repair the whole duct system.

Leak sealing
Save energy costs and improve comfort by sealing leaks. A qualified technician can detect leaks or you can find them by visual inspection. Weatherstripping creates tight seals between movable parts such as doors and windows — and is easy to install. Other sealing options include caulk, gaskets for outlets and switches, fireplace draft stoppers and attic door covers.
Savings: Up to 20%
Window film
Installing window shrink wrap can reduce heat loss through drafty windows.
Savings: Up to $35
Ceiling fans
Run ceiling fans in a clockwise direction to circulate warm air trapped near ceiling (updraft). Turn off when leaving room to save energy. Install ENERGY STAR® certified fans that offer up to 44% more efficiency than standard models.
