Duct testing Frequently Asked Questions

Q: What is a duct leak test?

A: A Duct leakage HERS test is a pressure test to measure any air loss in your duct system.  The HERS Rater seals off the duct system to pressurize it. Using special duct testing equipment that measures the loss of air in the system measures the efficiency. The Energy Department found that the average homes duct system leaks approximately 30% and made duct leakage testing mandatory Oct 2005.

A:  Home Energy Rating System Rater (HERS Rater) is a person Trained and Certified by a State approved organization through the California Department of Energy to perform Testing pertaining to conserving energy. HERS Raters can perform many services from duct testing to builder inspections for LEED or Energy Star programs, energy credits, or other energy saving inspections.


Q: I'm a contractor and only changed out the condenser.
Do I need a HERS Rater Duct Leakage Test?

A:   Yes. As of Oct 2005 changing or adding the coil, condenser, or furnace or adding more than 40 feet of ducting needs a HERS Rater duct leakage test. The City required the CF-6R and CF-4R forms before finalizing the permit prior to January 1 2010.

  Effective January 1 2010 the DOE added a Refrigerant Charge Measurement and changed the forms to the CF-1R, CF-2R, and the CF-3R.  We can provide you with all of these forms after the HERS Rating is completed.
