Seal air infiltration into the home
If your home is not sealed to today’s standards you could be spending 30% or more on your energy bill than necessary. Infiltration refers to airflow through gaps or cracks around windows, or in walls or flooring. Using caulk or other means to fill in the holes you can access will help to seal the building envelope so that less energy will be needed to maintain the temperature in your home. Having a home energy audit conducted will also give you more information about the most cost effective changes you can make to reduce costs.
Seal ducts located outside of the building.
If you have ducts that run through your garage, attic, basement, or crawlspaces they may be susceptible to extreme temperature deviations from the portion of the home where the temperature is regulated. Sealing and insulating these ducts will result in a reduction of energy consumption.
It may be hard to believe, but if your outlet covers are not properly insulated, air could be entering your home around them. Use outlet insulators to help seal the space behind the outlet and lower your energy bills.
