Energy Savings

Does your Home Experience…

  • High Energy Bills?
  • Constantly Running System?

Over 90% of existing buildings located throughout North America have air duct systems that contain small holes and cracks that reduce the level of comfort and increase heating and cooling costs.

Leaks are caused by a variety of factors including the age of the dwelling, type of construction, type of ductwork and local building codes.

Repairing and patching leaks in HVAC duct systems saves cooling, heating, and fan energy. In air-based systems, ducts deliver all of the heating and cooling to conditioned spaces. Any duct leakage translates into extra air that must be supplied so sufficient heating or cooling reaches the conditioned space. This not only increases effective heating and cooling loads, it also increases fan energy due to increased flow and/or run time. Sealing duct leaks reduces the amount of heated or cooled air the supply fan must handle to deliver the same amount of air to the conditioned space.


Healthy Space & Comfort

  • Air Quality Problems?
  • Excessive Dust?
  • Air Contamination or Odor Issues?

Duct leakage may be causing your indoor air quality problems. A good transmission gets power to all the wheels of a car, just like a good air duct system gets air to all the rooms of your home or building.

In Residential buildings, the problem with leaky ductwork is that air can not only leak out of you HVAC system and air ducts — untreated and unclean air and contaminants from the crawlspaces, attic and other place can actually be pulled in to the air you and your family breath. Since so many air duct systems leak and pull bad air in (we find 20 to 40% leakage in 3 out of 4 homes we visit), poor air quality is a problem that many homes have.
