Tips from Efficiency Vermont on saving energy, money this summer

As summer finally kicks in, the folks at Efficiency Vermont have some tips on how to stay cool on hot days and spend less on energy.

  • Block the heat. When it’s hotter outside than inside, close windows and draw window coverings against direct sunlight.
  • Is the house hotter than the outdoors? Open your windows and use a window fan – blowing out. That will push out hot air and pull in cool air through other, nearby open windows.
  • Control moisture. Use your bathroom fan to remove shower heat and moisture. If you need to install one, choose a quiet, low-energy model with the ENERGY STAR label. Be sure to duct it to the outdoors to avoid moisture and mold problems.
  • Adjust your schedule. When possible, do tasks that produce heat and/or moisture like dishwashing, baking, laundry, showers, etc. in cooler evening hours.
  • Cool down your lights. Replace incandescent bulbs with ENERGY STAR labeled LEDs which stay cooler and use about 80% less energy.
  • Dry clothes for free. Hang laundry outside to dry and save the cost of running the clothes dryer while reducing moisture in the house.
  • Using A/C? Keep heat out by making sure there are no gaps along the sides of your window unit or between window sashes. Clean air conditioner filters regularly. If buying, get the smallest ENERGY STAR labeled unit appropriate for the size of the room you’re cooling. Search “Properly Sized Room AC” at for more details.
  • Consider a heat pump.  A ductless heat pump unit is a tremendous energy saver for both cooling and heating. Find out if a heat pump is right for you at
  • Insulate & air seal. An insulated, air-sealed house stays warmer in winter AND cooler in summer. A Home Performance with ENERGY STAR contractor can do a whole-house assessment and make improvements, now or over time, within your budget. Rebates and financing are available. Learn more at
