About Us

Committed to providing you excellent and honest service, so you always choose NorCal Auto for your repair & smog needs.


Established in 2011, NorCal Auto quickly became a favorite in Chico for auto repair and smog services.  Customers appreciate the affordable prices, friendly atmosphere and trustworthy relationship with owner and mechanic Sean Loch.  

Sean went to the Chrysler Dealer Apprenticeship Program at Mercer County Community College in West Trenton, NJ.   He moved to Chico in 2003 where he worked as a mechanic and smog tech for almost a decade before opening his own shop.

NorCal Auto is not just your average auto shop.   Sean specializes in smogs including his "no pass, no pay" feature.  His shop also specializes in computer system diagnosis, smog check failure and light duty maintenance.
