Estimate the cost of supplemental heat during cold winter months with the Space Heater Calculator.

  • Set your thermostat between 76 and 78 degrees in the summer and 68 degrees or lower in the winter.
  • Use a ceiling fan to circulate air in the summer months to make you feel cooler.
  • Get your HVAC system serviced every year including a check on refrigerant levels, the compressor, hoses, ductwork and thermostat.
  • Clean or replace air filters regularly.
  • Invest in a programmable thermostat.

Lighting & Appliances

Calculate your savings by switching to energy-efficient CFLs or LEDs with the Lighting Calculator.
Find out how much energy the appliances in your home use with the Appliance Calculator.
Use the TV Calculator to compare energy costs based on the type of television you own.

  • Keep light fixtures and bulbs clean. Dust absorbs 50 percent of light.
  • Let food cool before putting it in the refrigerator. Hot foods will raise the temperature in the fridge and make it work harder.
  • Consider grilling during summer months. Using an oven makes your home hotter.
  • Wash full loads of clothes and use cold water when possible.
  • Don’t run the dishwasher unless it’s completely full.

Around the House

  • In the summer, close curtains and blinds on the sunny side of your home to block out the heat. In the winter, take advantage of the sun's warmth and open drapes in south facing windows.
  • Seal up leaks by weather-stripping doors and caulking windows.
  • Close the fireplace damper when you aren’t using it.
  • If your water heater is in an unheated space, wrap it in an insulation blanket to prevent it from losing heat.
  • Turn the water heater off if you are going to be gone more than three days.
  • Smart landscaping can provide shade to your home and significantly reduce your cooling costs.
