Beat the Heat with Summer Energy-saving Tips

Hot weather is finally here, and that can mean increased energy use (and higher bills) as we cool our homes and businesses. Idaho Power has a few tips to stay cool and manage your summer energy use when it’s hot outside.

  • Close doors, windows and blinds during the day or when you’re away, especially on the east and west sides. If safe, open your windows at night or in the morning to let in cooler air.
  • Do laundry and run the dishwasher in the early morning and late evening hours to avoid adding heat to your home in the warmest part of the day.
  • Install a smart or programmable thermostat to give your A/C a break at night and when you are away without sacrificing comfort when you need it. Idaho Power offers a $75 cash incentive when you install an internet-enabled smart thermostat in a home with an electric furnace or heat pump.
  • Weather strip doors and windows to prevent losing cool air to the outside.
  • Install a ceiling fan in rooms used frequently. Moving air can help you feel up to four degrees cooler. Ceiling fans are effective in homes both with and without A/C.
  • Turn the A/C off when you’re going to be gone for an extended period.
  • Check your A/C’s air handler or furnace filter. Dirty filters reduce a system’s efficiency.
  • Consider installing an attic fan to draw hot air out of the house.

Idaho Power also reminds customers that summer rates went into effect June 1. Customers may see an increase on their next few bills due to summer rates and increased energy use. Our area experiences the highest demand for energy in the summer, so rates increase from June through August — due in part to higher wholesale prices Idaho Power pays for energy in the summer months.

If you’re looking for more ways to save energy, Idaho Power’s 2022 Energy Efficiency Guide is available online. This year’s guide includes tips on using energy wisely throughout the year, information on whole-house fans, what to look for when hiring a contractor and more!
