Load & DesignQuestion 18 of 110
Under California energy standards, duct leakage in many new and altered systems must be verified by which method?
a.Visual inspection only
b.A duct leakage (pressurization) test by a certified rater or installer
c.A refrigerant pressure test
d.A combustion analysis
Explanation
Title 24 requires duct leakage testing for many new installations and changeouts, typically verified through a pressurization test. Sealing ducts reduces energy waste and improves delivered airflow. Results are often confirmed by a HERS rater.
