  • Visually inspect all windows and exterior doors for missing caulk or windows putty
  • Check the bottoms of exterior doors and thresholds and replace when necessary
  • Have a trained professional inspect the windows and door to determine if they are in need of serious repairs or replacement

On a windy day, safely use a lit stick of incense to check for air leaks.  If the smoke flows in a horizontal direction while holding the stick close to windows and doors it can help identify an air leak.

  • If you have a fireplace, close the damper when not in use *FREE TIP*
  • Install foam gaskets or insulation behind lights switches or outlets located on exterior walls
  • Do you have a kitchen exhaust fan?  If so, use a magnetic cover to keep air from escaping when not in use
  • Seal holes and cracks in exterior walls, crawlspaces, and basements where HVAC ducts or plumbing lines penetrate
  • Use dense foam board to cover up crawlspace vents
  • Install proper weatherstripping around the perimeter of attic access hatches and pull-down stairs
  • Ensure all vents are not covered by furniture or curtains or rugs so air can circulate *FREE TIP*
  • Seal leaky duct connections properly using a foil backed tape.  It may sound odd, but the normal gray duct tape will dry out and come loose so it should not be used.
  • Limit your use of space heaters.  Yes they produce heat in close proximity however they consume a lot of electricity.
  • Set the thermostat setting to maintain reasonable comfort levels when you are at home.  Reducing the temperature by 2 degrees in the winter or increasing by 2 degrees in the summer can make a difference.  *FREE TIP*
  • Consider installing a programmable thermostat to control temperature when you are away from home or on vacation.

  • Do not leave the television on for background noise or when you are not watching it.  *FREE TIP*
  • Set your computer to hibernate or standby mode after 30 minutes of inactivity and set the monitor to less time.  Screen savers generally do not save energy and some screen savers are graphic-intense and use more energy to display the images.  *FREE TIP*

  • Always check for leaks if you hear water running or a hissing sound and make necessary repairs.
  • Install an insulation blanket around the water heater to help retain the heat
  • Install a low-flow showerhead in your bathroom.

  • Crawlspace Wall Insulation:  R-10 with vapor barrier (foam board)
  • Duct Insulation:  R-13 in unheated areas
  • Rim Joist Insulation:  R-13 (4 inches)
  • Consider having a professional perform a blower door test on the home to determine if there are leaks around windows or doors that need to be sealed better.
  • Have a thermal imaging scan performed on the house to see if there are places where heat is escaping
  • Install storm windows to provide an additional insulation barrier and to reduce air leakage
  • Replace your old, leaky windows with new, energy-efficient double pane windows
  • Insulate all duct work that is in an unconditioned space such as your attic or crawlspace.
  • Consider having the ductwork replaced if it is old to eliminate pin holes or other voids that cannot be easily discovered.
  • When you are in the market for any new appliance, make sure to pay attention to the energy star rating and the big yellow rating sticker.
  • If your water heater is over 10 years old, consider replacing it with a more energy efficient model.
  • Replace your air conditioning unit with a new unit with a Seasonal Energy Efficiency Ration or SEER rating of 14 or higher.
  • Replace your furnace with a new unit with an AFUE Annual Fuel Utilization or AFUE rating of 95% or higher.  This is a rating on overall efficiency.
