About Us

CNG COMPLETE is a family-owned business located in Utah County, at 480 S. Main Street, Springville UT. We focus on personal service and attention to detail. Our goal is to make sure every customer is 100%  satisfied with their results!

My name is Kelly Bronson, and I'm the founder of CNG Complete. CNG has been a passion of mine ever since my first natural gas car, seven years ago. I took my passion to Dixie College where I learned to install CNG conversion systems myself. I started with my own vehicle, but quickly started receiving requests from friends, family, and others. It has now become my primary business with great success.

I've repaired, and converted numerous vehicles with fantastic results! In fact, I still drive the same truck I installed my own kit on. That truck has now traveled over 120K miles on natural gas, and I have saved over $53,000 in fuel costs with that vehicle alone! I would love to help you achieve similar savings.

Give me a call, e-mail, or just stop by the shop. And I will personally work with you to answer any questions you may have. You can even call and make an appointment to bring your car in, for a free consultation, so I can give you an accurate bid on the best system for your vehicle.

I strive to work with my clients and do all I can to keep the prices low. If you have a quote from another shop, I can usually match, beat, or out-perform them. I have tested many other regulators and the ones we use have had the best, and most consistent performance. Combine that with my experience, and high quality workmanship, and I guarantee you will love the outcome!

It's also important to understand that most kits installed are not EPA certified. That goes for almost every shop in UT, not just ours. Some vehicles can be, but this involves a significant extra charge. For more information and general education on CNG, please visit our Learn about CNG page
