Start by setting your thermostat to 72 degrees. Then move it up 1 degree each day in the summer until you find the highest setting that still maintains your family’s comfort. Then do the opposite in the winter. Each degree up in the summer and down in the winter can save roughly 3% on your monthly energy bill. Don’t go too extreme, however. You do want your HVAC to run regularly throughout the day to maintain healthy levels of indoor air humidity. Another way to save is when you leave for work, adjust your thermostat up 7-10 degrees in the summer. The savings over those 8-10 hours can add up to roughly 10% off your energy bill. And, a smart thermostat can automatically make those adjustments for you, and efficiently get your home’s temperature back to normal before you arrive back home. See more Energy Savings Tips.
