HOME ENERGY SAVINGS

The Department of Energy recommends setting the thermostat no lower than 78⚬ F when you are home and need cooling. Set your thermostat at as high a temperature as comfortably possible. The smaller the difference between the indoor and outdoor temperatures, the lower your overall cooling bill will be since the unit will not need to run as frequently.

Avoid setting your thermostat at a colder setting than normal when you turn on your air conditioner. It will not cool your home any faster and could result in higher electric bills. Assuming that your air conditioner is properly sized and operates on a 20-degree differential (the difference between the temperature inside and outside the home), an AC system would be operating continually if the thermostat was set at 78⚬ F when the outside temperature is at 98⚬ F or more.

During summer months in Arizona, we often experience multiple days with temperatures at 100⚬ F or higher. If you’re not at home during the day, set your thermostat higher to stay within the 20-degree differential. Consider a programmable thermostat so that you control how often and when the air conditioner operates.

The more frequently your AC cycles on and off, the more energy you use. The goal is to keep the thermostat set at a temperature that is comfortable for you, but high enough that the system doesn’t cycle on and off too frequently.

If the temperatures outside continue to increase, but you are not also increasing your thermostat, and the temperature differential between the outside and inside temperatures become larger, the AC unit will cycle on more frequently and result in higher energy usage and larger electric bills.

Also note that if you have a second refrigerator or freezer that is in unconditioned air (porch, garage, etc.), those units will also work harder to maintain the internal temperature while the outside temperatures continue to rise, resulting in more consumption and higher energy costs. While you might not do anything different from day-to-day or week-to-week, the outside temperatures do play a big part in your energy consumption.
