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:
- Electric plenum heaters
- Electric boilers
- Thermal-storage systems
- Radiant-heat systems
- Heat pumps
- Fan-forced heating
- Baseboard heating
- Snow and ice elimination systems
- Heat-recovery air exchangers
- Air conditioning
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.
