Berkeley Smog Test Only Center, Berkeley

The state-licensed technicians at Henry's Smog Check have conducted more than 50,000 smog checks all in the name of California's air quality. They welcome cars of all makes, models, and ages, gauging the emissions of convertibles and mobile homes alike. Their expertise enables them to complete most tests in approximately 20 minutes—though vehicles with complex parts may require a bit longer—and they cut down on long lines and exaggerated sighs with online booking. Clients can submit their rides for any reason, whether they are keeping abreast of biennial certification requirements or transferring their car to a new owner who could never love it like they did. Regardless of motive, the staff preserves a cheery and professional ambiance.
