Heating and Cooling

Heat and cool more efficiently

Heating and cooling may seem pretty straightforward, but there are actually a variety of technologies you can use—many of which can save you money.

These  electric heating and cooling technologies operate with 100% or more energy efficiency:

Tips for reducing your heating and cooling costs

  • Service your heating and cooling systems every year for peak operational efficiency and safety.
  • Adjust your thermostat. Set your thermostat as low as is comfortable in the winter and as high as is comfortable in the summer. You’ll save 3% on the day’s heating or cooling costs by changing your thermostat temperature by one degree (higher for cooling, lower for heating) for that 24-hour period. Maintain those settings and you’ll save 3% all season!
  • Clean or replace heating and cooling filters once a month.
  • Clean air registers, baseboard heaters, and radiators as needed.
  • Make sure air returns and registers are not blocked by furniture, carpeting, or drapes.
  • Use kitchen, bath, and other ventilating fans wisely, turning them off as soon as they have done the job. Depending on where they are used, a ventilating fan will complete 8–15 air changes per hour (ACH). If left running when not needed, this will cause your heating or cooling system to run more often.
  • During the heating season, keep draperies and blinds on your south-facing windows open during the day to allow the sun to help warm your home.
  • Close drapes at night to help reduce heat loss.
  • During the cooling season, keep the window coverings closed during the day to prevent the sun from heating your home.
