Quality Assurance: Visit our Facility and See for Yourself!



DIA.jpgDiesel Service & Supply stands behind the quality of all the used generators and industrial power equipment we sell. If you are not convinced by the pictures, videos, check-in reports, load tests, customer experiences and sales associates’ knowledge about the generator you are interested in, then we invite you to come visit our expansive yard and shop facility to witness a load test and see the professional operation we have going on here.

We are conveniently located near the middle of the country, just 20 minutes from Denver International Airport in Brighton, Colorado. In order to make your visit as efficient as possible, we can arrange for transportation to and from the airport so you can be in and out the same day in many instances (for most locations throughout the U.S. and Canada).  We can also assist in logistical details for overnight stays here if you need more time or want to stick around and enjoy Colorado for a day or two while you are here.

While at our shop, we’ll give you a tour of our 140,000 sq. ft. facilities and load bank test the used generators you are interested in to give you the confidence and security you need to ensure you are making a sound purchasing decision.

We stand behind the quality of both our products and our people - which is exacctly why we offer our Certified Generators and Satisfaction Guarantee. We invite you to speak with one of our sales associates today by calling 800-853-2073 or contact us online if you would like to set up an appointment to inspect one of our generators for yourself.
