Duct tests are performed to assess potential leakage in the HVAC system. Our technicians execute these tests on each duct system individually by sealing off the system openings and using a machine called a duct blaster.

NC building and energy codes require leakage testing for all residential duct systems (except those located entirely within a home’s thermal envelope). Upon passing the test, the home receives a duct test certificate for city inspection. 

Duct leakage wastes both money and energy, and often causes uncomfortable temperature disparities in a living or working space. In addition, leaky ducts can negatively impact the indoor air quality of the building by facilitating mold growth within the duct system.
