PORTLAND — Energy Trust of Oregon advises it is time to prepare for the big chill, especially with below-freezing temps across much of Eastern Oregon this weekend and during the next week.

Energy Trust is a nonprofit that makes it easier for people to use less energy while keeping their homes warm. With a cooler and wetter winter forecast, thanks to La Nina, and the recent 2025 Oregon Climate Assessment predicting more freezing rain and ice storms in the future, Energy Trust of Oregon has provided its top tips for keeping your home warm while saving money on your energy bill this winter.

Set the temp: At night or when no one is home, save on energy costs by lowering your thermostat to 58-60 degrees. When you are home, keep the thermostat at 65-68 degrees. If you have a heat pump, turn the thermostat down no more than 3 degrees at night because heat pumps work best when maintaining a temperature. You also can install a smart thermostat so it can adjust the temperature automatically and help you save energy all year long.

Seal those gaps and openings: Small gaps and cracks in a typical home can add up to the same loss of energy and comfort as leaving a window open year-round. Use caulk or spray foam to seal small holes and cracks and use weather stripping and door sweeps to seal drafty windows and doors. When not using a wood stove or fireplace, close the dampers to prevent a draft — but wait until several hours after the fire is out and the ashes are cold.

Take advantage of the sun: Heat your home with help from the sun by leaving window shades or blinds open during the daytime. At night, close the window coverings to help keep the heat in.

Check air filters once a month and schedule maintenance: During the coldest months when your heating system is working its hardest, check your air filter and change it if it looks dirty. A dirty air filter will slow airflow and make the heating system work harder and waste energy. Now’s the time to schedule maintenance service for your heating system. An HVAC specialist can help catch issues before you’re left in the cold.

Utilize rugs: If you have bare floors, cover them with rugs to add comfort and help retain heat, especially if there is little or no floor insulation in your home.

Find support: If you need assistance with utility bills, check with your utility for options and programs. For more information about the incentives we offer, visit Energy Trust’s website. Energy Trust offers higher incentives for people with lower to moderate incomes.

It’s also a great time to schedule maintenance service. With product shortages and busy contractors, planning ahead will keep you warm. For more energy-saving DIY tips, visit energytrust.org/residential/DIY.
