How’s my ducting?

National studies of residential duct systems indicate that many duct systems leak 40% or more.  This means that 40% of cooling capacity, heating capacity, and utility dollars are going into unconditioned space.  Duct leaks also cause pressure imbalances inside the home causing indoor air quality problems.

We find many duct systems to be poorly designed, installed or don’t have a improperly implemented maintenance program. A sure sign of duct problems is rooms that heat or cool unevenly.  Dust streaks around supply vents are often thought to be caused by a dirty duct system.  Most of the time dust streaks around supply vents are caused by leaks in the duct system between the “bucket”, the sheet rock, and the supply vent cover.  A venture effect caused by the moving air sucks dirt, humidity and heat directly from the attic.

Poorly insulated points or sections of ducting can cause moisture and microbial growth to occur.  Air is then circulated past the molds growing in the duct system, distributing mold spores thru out your home. Since these spores are created after the filter; even the best filtration system can’t fix this duct problem.

Proper duct design is also important in achieving and maintaining proper system operation and efficiency.  Some residential homes and commercials buildings have supply air outlets placed near the interior walls of the home.  This poor duct installation practice creates a need to run high duct static pressures in order to push air all the way from the interior wall to the exterior wall where the majority of the heat enters your home.  This one poor duct design feature creates a host of potential problems.
