Summer Energy Efficiency Tips

The official start of summer is still a couple of weeks away - but temps are already hitting 90º! Here are some tips to save energy (and money) during hot weather while maintaining comfort.

  • ​The Department of Energy recommends that you set your air conditioner thermostat to 78ºF (or as high as is comfortable for you) and bump it up by 5º to 7º when you leave for an extended period of time. (Heat pumps are designed to efficiently overcome about a 20 degree difference in outside and inside temperatures.)

  • Operate your dryer and dishwasher after 8 p.m. on hot days and let your dishes air dry. In fact, it’s best to avoid the use of any major appliances between 2 and 8 p.m. Why? Appliances generate additional heat - which your cooling unit must overcome.

  • Avoid heat-generating incandescent lighting and use a microwave, toaster or outdoor grill instead of the oven when possible.

  • Close blinds during the day (to keep out solar heat) and open them at night.

  • Set your ceiling fans to rotate in a counter-clockwise direction. This will create a “wind chill” effect that make the room temperature feel cooler.


And here are a few more tips that apply all year long:

  • Caulk and install weather-stripping around windows and doors to stop air leaks.

  • Make sure you have at least 10” of blown attic insulation over all heated and cooled areas. (10" equals approximately R38.)

  • Seal gaps in floors and walls around pipes and wiring.

  • Service your HVAC unit ANNUALLY and change air filters MONTHLY. Inspect ductwork and repair any gaps.

  • Keep your outside air unit clean and clear of debris.

  • Keep all windows and doors near your thermostat closed tightly.

  • Keep heat sources such as lamps and appliances away from your thermostat.

  • Replace incandescent bulbs with compact fluorescents or LEDs – they use 75% less energy.

  • Turn off lights, televisions and other electronics or appliances when not in use.

  • Install aerating, low-flow faucets and shower heads.

  • Fix any leaky faucets – one drop per second can add up to 165 gallons a month.

  • Wrap your water heater with insulation or install an insulating blanket.

  • Reduce hot water use by taking shorter showers and using cold water for the rinse cycle in your washer.
