  • Do jobs that produce heat and moisture (cooking and cleaning) in the coolest part of the day. Use your hood vent when cooking, and use a microwave when possible to cut down on cooking time.
  • Use LED lights (light emitting diode) which produce less heat. Keep off unnecessary lights to generate less heat in your home.
  • Install a programmable thermostat. A programmable thermostat can help you use energy more efficiently and save money on your bills by automatically adjusting your home's temperature based on settings you select. The thermostat can pay for itself within two years and continue to save you money in the future.
  • Take advantage of the weather and use outdoor drying in place of running your clothes dryer when possible.
  • Seal leaks around windows and doors. (In a pinch, you can use cardboard, plastic, or blankets to minimize drafts.)
  • Place any window AC unit on the north sides of the house if possible. Keep central air vents clear, shut doors to unused areas, and close floor and wall vents.
  • Plant trees to shade your HVAC or window unit. The sun beating down on the unit makes it work harder to keep you cool; providing shade may increase its efficiency up to 10 percent.
  • Plant shade trees on the west and south side of the house. Mature shade trees can cut cooling costs by 20-40 percent.
  • Water plants either in the early morning or late evening when evaporation due to heat and wind are at their lowest point. This ensures a more efficient watering of your plants and cuts down on your overall usage.
  • Move heat-producing items like incandescent lights and the television away from the thermostat. Their heat will make the thermostat think it is warmer and the AC will work overtime.
  • Keep out the hot daytime sun. Close curtains or blinds on the sunny rooms of your home. Install solar screens on west-side windows to reduce heat buildup.
  • Use a fan with your window AC unit to spread the cool air throughout your home. Or use a ventilating attic fan to help keep your entire house cooler.
  • Use your ceiling fan in the counterclockwise direction to help you stay cool. Your fan creates a wind-chill effect. Just remember to turn off your fan when you leave the room. Ceiling fans cool people – not rooms.

When the weather outside is extreme, your utility bill can be extreme, too. Levelized Billing Plan can help you keep your bills more level, no matter what the weather does. When you sign up for LBP, KUB recalculates your payment each month based on your latest 12 months of history. That rolling average means that bitter cold weather in January, for example, is somewhat offset by milder weather (with lower bills) in the fall and spring.
