Starting in September of 2019, a duct leakage test will be required for all residential new construction homes that have ductwork outside of the conditioned space. This includes ducts located in vented crawlspaces, ventilated attics, and attached storage rooms that are not conditioned.

In many states, a certification of some type is typically required. However, in Virginia’s case, the tester’s ability to operate the equipment is to be determined by the AHJ (Authority Having Jurisdiction).

Luckily, Retrotec’s DucTester systems come with an online training module that provides the user with a Manufacturer’s Certification. This can be presented to building inspectors to provide proof that the tester is knowledgeable when it comes to testing ducts for leakage. This is unique only to the Retrotec brand of testing equipment.

A recent Retrotec webinar, “Duct Testing Best Practices,” walks through duct testing procedures relevant to those looking to begin testing in Virginia.

In this webinar, Sam Myers covers all aspects of residential duct testing including total leakage, two methods for testing leakage to outside, testing at rough-in, exposing leaks, and apps that make testing faster and easier.
