HERS duct tests are now mandatory statewide

.

The new 2016 Title-24 Building Efficiency Standards  require mandatory HERS duct testing for all new construction and HVAC changeouts where the ducts are altered.

.

In addition minimum airflow requirements must be met and tested by an independant HERS rater.

.

We recommend HVAC installers become familiar with these new rules and perform their own “rough-in” duct tests prior to completion of the project to insure the ducts are not leaking before drywall installation.

.

Also, remember that all gaps between the supply/return boots and the surrounding drywall must be sealed (caulking is fine) before the HERS duct test.  The HERS rater must visually verify that these gaps are sealed.  Most importantly if they are not sealed it is likely the system will fail the duct tests.
