About DES in Ontario

Established in sunny, Southern California, Diesel Emissions Service (DES) opened its Ontario location in 2011 and has been providing emissions solutions and options to thousands of clients throughout the region.

Located near the intersection of Interstate 15 and 10, our Ontario facility is a convenient location, easily accessible for servicing, and a perfect option for those diesels involved in the shipping and logistics in and out of SoCal.
