Stay Cool This Summer with These Simple Energy-Saving Tips Use floor and ceiling fans On those nice days when it doesn’t feel as hot, turn off your AC and use ceiling, floor and table fans instead. Fans use a fraction of the energy that central AC units do — so when the job can be done by a fan, pick the fan. Concentrate your AC When it is just too hot to use fans, try to concentrate your air conditioning flow to the rooms or areas of your home that you use the most. This is more energy-efficient than trying to cool your entire home. Close the vents in those rooms you don’t frequently use, like spare bedrooms and the basement and only open them when you need them. Don’t cool an empty house When you leave for that summer vacation, remember to turn up the thermostat to 85-90°F so you don’t cool your home when no one is there to enjoy it. Upgrade to a smart thermostat If you haven’t upgraded to a smart thermostat, now is the time to do so. These thermostats can change the temperature automatically based on your preferences, so you can set a lower temperature when you’re home and a higher temperature while you’re away at work.

Reducing the amount of moisture in the air can make your home seem much cooler, without having to turn on the AC. Upgrade your cooling units Because older appliances tend to be less efficient, it might be time for you to upgrade to a newer, more energy efficient AC unit.
