HFC Emission Reduction Measures for Mobile Air Conditioning - Addition of AC Leak Test and Repair Requirements to Smog Check

This page last reviewed January 5, 2011


This measure proposes to explore the addition of a new motor vehicle air conditioning (MAC) system leak test and repair requirement to the existing California Smog Check program for HFC-based MAC. Under this proposal, all vehicles that pass Smog Check would have MAC that are either nearly leak-free or empty and excluded from further use of the MAC system unless the leak is repaired. Vehicles that are determined to have unacceptable leak rates would be required to be repaired as a condition for registration. Considerable cooperation with the Bureau of Automotive Repair of the Department of Consumers Affairs is necessary before mandating that a new procedure be integrated into the statewide Smog Check program.
