Blower door test is performed to verify building leakage matches the target CFM50 on CF1R when the contractor uses the prescriptive alteration approach.
Fan efficacy test is performed on new system or new duct work to measure the blower fan's consumption. Fan efficacy is measured in Watts/CFM when the air handler is operating at cooling speed.
Houses built prior 1977 may have asbestos as insulation and HVAC ductwork. Our trained raters will identify asbestos in all accessible areas of the duct system. CalCerts does not allow raters to do duct leakage test for homes with asbestos ductwork.
AIR FLOW MEASUREMENT TEST
Testing the system's airflow read to make sure enough air is entering and exiting the system continiously. This test will be peformed if required by CalCerts based on scope of work.
