Set your dial to 78 degrees – yes 78 degrees

June 28, 2019

Setting your air conditioner at 78 degrees when you are home has been one of Rocky Mountain Power’s most effective energy saving tips. But many customers question how to stay comfortable and cool at a higher setting.

Running AC at temperatures lower than 78 degrees can increase your electricity bill by up to 8 percent. So the key is taking alternative steps to keep cool instead of just relying on your air conditioner.

Get some fresh air. Open windows throughout the house and let the night air cool your home. Use fans to circulate the fresh air.

Keep clear of the sun. In the early morning, close the blinds and windows to keep the sunlight from heating up the house. Blackout curtains and plantation shutters are particularly effective in reducing heat gain.

Fan out. Using ceiling fans and portable fans can be very effective when it comes to keep you cool. They keep air circulating, create a cooling effect and are often a comfortable alternative to running your AC.

Reduce indoor heat. Avoid the use of heat-producing appliances such as ovens, dishwashers and blow dryers. Grilling outside, washing dishes by hand and air-drying clothes are great alternatives.

Be AC savvy. Use a programmable thermostat to set your air conditioner to run only when you are home and set it to 85 when you’re away.
