Energy Loss & Associated Costs Can Be Attributed To Air Leaks & Insufficient Insulation

EnergyAccording to ENERGY STAR®, one of the most cost-effective ways to increase your home’s energy efficiency is to improve the building “envelope,” which consists of outer walls, windows, floors, ceiling, and other openings. A residential envelope that is properly sealed and has proper insulation can have a significant effect on your monthly utility costs and energy efficiency. Approximately 20% of air moving through a typical residential AC duct system is wasted due to leaky ducts, and improperly sealed connections.

It’s a good practice to have your air ducts checked and have leaks sealed when your air conditioner is professionally tuned up each year. Insulation can be checked and replenished as needed. It’s also a good practice to have air leaks around windows and doors caulked, and weather-stripped. Check and add insulation as needed to help improve your home comfort

Sealing air leaks and weather stripping can benefit other areas of your home:

  • Decreases pollen, dust, and insects from entering the home
  • Helps control humidity indoors
  • Increases indoor air quality
  • Reduces noise from the outdoors
  • Helps optimize indoor comfort

In general, most homes in this country have a significant number of air leaks and don’t have enough insulation. The sum of air leaks, holes, and gaps in the typical home envelope is equivalent to leaving your windows open every day.

It’s to your benefit to have your ducts checked and sealed, and to properly insulate your home for keeping it warm in winter and cool in the summer. Stay comfortable!
