Load & DesignCâu 18 / 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
Giải thích
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.
