DUCT TIGHTNESS TEST

All ducts passing through unconditioned space (attics, garage ceilings, cantilevered floors, etc) must be tested for leakage. The test should be performed as soon as the supply & return ducts are ‘roughed in’ – before they are covered by insulation & drywall. The furnace/AC does not need to be installed for the test. Insight can help train your employees in cost effective duct sealing techniques (use Mastic – NOT foil tape) and serve as the approved 3rd party to test those duct sections for leakage. This process does not have to add significant time & cost to your projects if you consult with Insight for cost saving strategies.
