- Close blinds and drapes during the day to keep the sun’s warming rays at bay. Where practical, plant trees and shrubs that provide shade in summer and sunlight in winter.
- In extremely hot weather, your cooling system works harder to close the gap between the high outdoor temperature and the cool indoor thermostat setting. To lessen the difference and lower cooling costs, set the thermostat as high as you can while maintaining your comfort level. Employ a programmable thermostat to adjust the settings a few degrees higher when no one is home or your family is sleeping.
- Using a ceiling fan in conjunction with your air conditioning can allow you to increase the thermostat setting by about 4 degrees with no reduction in comfort. Just make sure to turn ceiling fans off when no one’s in the room.
- During the hottest months, it’s all the more critical to replace any remaining incandescent lightbulbs with LED bulbs. The wasted heat from the old bulbs affects energy use and creates wasteful and unwanted heat.
