Air Duct Comfort and Safety

Air duct leakage lowers the heating and cooling capacity and lessons your equipment’s life expectancy. Just 20% duct leakage of the total airflow causes the efficiency of your system to drop as much as 50% or more. Many common comfort complaints are due to duct leakage caused by poor design and installation, as well as lack of proper sealing.

Studies show than more than 50% of homes have at least one room that is too hot or cold. Many people mistakenly assume this is unavoidable. You don’t have to put up with these problems.

Ductwork is often located in attics, basements, or crawlspaces. Air handlers, including furnaces, and their supply and return plenums are often located in similar unconditioned spaces or mechanical rooms. If your return ducts leak, they draw air directly from these areas and literally pump it into your home. This “bad-air” is often contaminated with dust, mold, mildew, excess humidity, and potential toxins such as pesticides from termite treatment, combustion gases, automobile exhaust, and even radon. Leaking supply air ductwork can create lower pressures inside your house that can also draw in these same containments too.

While the increase in your energy costs and your loss of comfort is very important, protecting your health and safety is the most important reason to air seal your house and ducts properly.
