You know that little breeze that sneaks in around the window in the dining room? And the draft you feel as you pass electrical outlets in the living room? Most homes have areas of air infiltration like these, where unwanted outdoor air gets in and conditioned air flows directly out, with energy wasted in each direction.
Those Little Air Leaks Might Be Costing You A Lot -- Get Them Plugged
Too-warm or too-cold outdoor air coming in makes it harder for your home comfort system to cool or warm your home, as it must use extra energy to keep up. Here in the Twin Cities metro area, this is a problem year-round during the hot, humid summer and sub-freezing winter weather. Conditioned air warmed or cooled by your furnace, air conditioner or heat pump, flowing out of the house through leaks – without doing you one bit of good – is also a big waste of energy.

Even greater amounts of conditioned air are wasted through air leaks outside your main living space, in attics, basements, attached garages and especially ductwork. These “little” leaks compromise the ideally airtight and energy-efficient envelope of your home, adding 10 percent to your energy bills each month, according to Energy Star. So it literally pays to seal them up and add insulation. To get started:

  • Inspect the attic for leaks where walls meet the roof, where plumbing pipes enter the house, around the base of knee walls and near the chimney, for example. Seal leaks with appropriate material, including caulk and weather stripping.
  • Check for leaks around the air hatch between home and attic. The hatch can be sealed with weather stripping, then insulated.
  • Schedule a professional duct inspection, perhaps along with your annual A/C or heating system maintenance visit. For best results, ask your HVAC contractor to seal the duct system to minimize future leakage.
  • Insulation should also be added to the ducts, especially those outside the living space (conditioned areas) of your house.
  • Then move on to your attached garage and lesser leaks in the home’s living area.
