3 EXEMPTIONS TO A DUCT LEAKAGE TEST
- 1HERS rater previously tested the duct work, ducts have not been altered since the previous test took place & a duct leakage verification certificate can be presented.
- 2Less than 40' of duct work is existing or altered in unconditioned space (crawl space, between walls, garage, etc.)

Installing a new furnace would trigger a duct test regardless of the amount of altered ducting.
