Duct Sealing

 Home / Services / Duct Sealing

Air Duct leakage affects your home comfort system in a variety of ways including poorer indoor air quality, a less comfortable atmosphere, and higher energy costs.

According to Energy Star in a typical, non-earth advantage home, 20 percent of the heating or cooling from a forced-air comfort system may be lost through leaks in the ductwork.


As a certified contractor, Columbia NW is trained to meet the duct testing and sealing requirements of the regional Performance Tested Comfort System (PTCS) program, the same standards as used by most utility incentive programs for ductwork.  A duct system that is well-designed and properly sealed will make your home more comfortable, energy efficient, and safer.


By eliminating heat loss or gain into unconditioned attic and crawl spaces we can be assured that all the heating and cooling you are paying for is delivered where you will enjoy it not the inhabitants of your crawl and attic spaces.  This will lower your monthly cost and reduce your carbon footprint.  A duct seal will improve the quality of your homes air as it will not allow dust and particles from your attic and crawlspace to invade your home.  A properly sealed home will deliver more air to all rooms thus improving hot and cold regions in your home.

1.  You have high winter and summer utility bills
2.  You have rooms that are difficult to heat or cool
3.  You have “stuffy” rooms that are never comfortable
4.  Your ducts are located in attic, crawl or garage spaces
5.  You find tangled or kinked flexible ducts in your home comfort system
