I have been using DES for several years for all of my DPF cleaning and maintenance needs and am very satisfied. Their staff is very knowledgeable and helpful; they usually diagnose problems quickly to get me back on the road. I appreciate the friendly and supportive staff and how they consistently communicate about my orders. I highly recommend Steve and his crew at DES.Kelly GranberryOperations Manager at Cross Petroleum
Best place around inland empire to get your filters cleaned out. I love the way they give you pictures of before and after of the work they do. Will keep going to them... no one in the inland empire does that and gets the filters as clean as they do. Thanks to Frederico, my mobile business will keep on doing work with them in the future.Jason MorenoCustomer Review on Google
Diesel Emissions Service installs and services the DPF systems in our fleet. They provide quality service and are very knowledgeable on their systems. I would recommend them to anybody in need of DPF cleanings or system repairs.Larry NobleShasta Union High School District
DES has provided us with excellent professional service since day one. They have a great selection of inventory including gaskets and clamps to finish each job. Every DPF we send them is returned cleaned, sealed and tested. Each cleaning comes with a report with test records, along with before and after photos of every DPF. DES is always willing to go the extra mile. Along with their great service, the turnaround time is second to none and Dave has even come in on a Saturday to help us out! I would suggest them to anyone.Dan FunkParts Manager of McCoy Freightliner of Portland
Being a small private school with a fleet of only twelve buses, we didn’t have any clout with anyone, but Diesel Emissions Service made us feel we were important to them and gave us much assistance in bringing our buses into compliance. Whenever there's a problem with a system, or just a filter that needs cleaning, they are always there. I have called at some pretty inconvenient times and they have always come. DES has gone to great lengths to keep our buses running for us. That's my idea of service.Jim SmithRio Hondo Prep
DES performs all of our scheduled maintenance on our DPF units as well as our Preventative Maintenance. They are also our mechanic of choice when our vehicles break down. For over 3 years we have used DES exclusively and never had a complaint. They are prompt, courteous and well aware of our scheduling needs.James NortonTrainer/Dispatcher Robla School District
