After running well for a couple of years, about a week ago, my generator stopped starting. When the usual troubleshooting failed, I guessed that it might be a bad fuel pump. A bit of research led me to Advanced Generator Service, a Cummins Onan repair service in Azusa California advancedgeneratorservice…. Watching Gary Patton, the owner, chief cook and bottle washer, made me very happy I'd decided against tackling this on myself. He however had the parts, dropped and repaired the generator and had me back on the road no time.

So, if you're in need in anywhere in Southern California Gary gets my highest recommendation.

Great Service provided by Gary & Laura ! We drove from LAX to Azusa to have our Onan Generator worked on. They have a good spot close to the fwy exit & plenty of parking & room to move around. We had some useful information explained to us by Gary that will help us in the future. They were upfront about pricing & we felt very comfortable with the atmosphere & professional service they provided. Thanks Again Gary & Laura
