Although your home performance contractor will develop a specific plan for your home, commonly recommended improvements for an energy-efficient home include:
Sealing air leaks and adding insulation
Sealing air leaks will make your home more comfortable and significantly reduce your energy bills.
Many air leaks in homes are more obvious:
- Electrical outlets
But other areas are even more significant sources of air leaks:
- Recessed light fixtures
Along with air sealing, your contractor may recommend that you add insulation. Many older homes are not well-insulated, and some have no insulation at all! Even new homes frequently have improperly installed or missing insulation.
Properly installed insulation in walls, floors, and attics:
- Moderates temperatures throughout the house
- Results in a quieter, more comfortable living space
- Makes your home easier and cheaper to heat and cool
Number one rule in air sealing – air seal before you insulate!
Improving your air ducts
Your home performance contractor may recommend the following energy-efficient home improvements:
- Sealing ducts with a heavy tape such as mastic, durable foil-backed tape, or aerosol-based sealant
- Insulating ductwork in attics, crawlspaces and unconditioned basements
- Balancing the duct system to circulate air to all rooms
