First Call, Last Call

Quick Look

First Call

A-1 Alternative Fuel Systems understands that providing a quality product goes well beyond the initial sale. We pride ourselves on having the industry's only "First Call Policy". As part of our warranty and support services, we provide our customers with a direct line to contact our technical support team - free of charge. Rather than point fingers, A-1 encourages our customers to make A-1 their first call when there is an issue with your alternative fueled vehicle. Regardless of what the issue is, our technical support staff will work with our customers to diagnose the issue over the phone - whether it is fuel system related or not. Once the issue is identified, we will either direct your mechanics on how to repair the issue or direct you to our network of maintenance and repair facilities located across North America.




 If we discover that your issue is not a fuel system related issue, our certified technical support staff will direct you to not only the appropriate company but also the appropriate person to resolve your issue. At A-1 Alternative Fuel Systems, we understand that getting in touch with the appropriate person can be half the battle to getting your vehicle back on the road. Additionally, as part of our "Last Call Policy", we offer our continued support even after we have referred our customer to the responsible party for the warranty/failure. An open ticket will remain with our technical support team and we will continue to follow-up with our customer and other vendor until the issue is resolved.
