Raise your air conditioner's temperature settings
Whether you’ve got a central air conditioner or window A/C units, you can save a significant amount of energy and cut carbon dioxide emissions by raising the temperature setting on your air conditioning unit.
How to raise your air conditioner's temperature settings
Most people can live quite comfortably at a temperature of 78°F. Rather than reducing your air conditioner’s temperature setting to a chilling 72 degrees, try raising it one degree at a time to see how warm it can be before you become uncomfortable. Remember, the higher you set your thermostat (in summer months), the more energy you’ll save.
If you don’t have a programmable thermostat, manually adjust the temperature on your air conditioner. While occupying your air conditioned space (at home or at the office), adjust the temperature upward one degree at a time to see what temperature works for you, striving for at least 78 degrees. Raise your air conditioner’s temperature in unoccupied spaces—at home while you’re at work, or at the office during non-business hours—and at night while you sleep.
If you do have a programmable thermostat, use it to your advantage. Set your thermostat to gradually increase temperatures while you’re around, then lock in the highest comfortable temperature setting so that it's consistent from one day to the next. Program your thermostat to raise the temperature even further when you’re away.
Raising your air conditioner's temperature settings helps you go green because…
- It prevents excess energy from being wasted, reducing carbon dioxide emissions.
On average, an air conditioner emits 2,263 pounds of CO2 every year. During the hot summer months, raising an air conditioner’s temperature 6°F can save 10 percent on cooling costs. In fact, for every degree the temperature is raised above 72 degrees, cooling costs drop by 3 percent and carbon dioxide emissions decrease by 121 pounds.
