My father doesn’t have a lot of money, but he desperately needed specialty work on his truck’s engine. Red mark quoted him fairly, did great quality work quickly, and went the extra mile for my father because he is a veteran. Whenever a business treats my dad this way it almost brings me to tears. Thank you for helping him out the way you did

Kris and his crew have been absolutely remarkable to work with on my truck conversion. I would HIGHLY recommend Redmark CNG.

Great on the phone. Not so much in person. Got the job for me fair price. Wish I knew how my system worked without youtube

Tony and Gary are GREAT! I asked around, EVERYONE says go here with your CNG Vehicles, or problems. These guys diagnosed the actual problem faster than my original source, and fixed it for half the quoted price of the other guys!!! EVERYONE I TALKED TO SAID GO TO THESE GUYS!!!!

Great to work with

Very quick and friendly service

Great place for CNG services.

Great service and quick response to my concerns. the owner Kris, was very knowledgeable and answered my questions. very happy Redmark was referred to us. thanks for a job well done.

Top notch customer service, got us back up and running in no time. Kris and his team definitely have it all, there is no substitute for knowledge and experience. Their efficiency in dealing with CNG issues is unparalleled.

The most professional CNG conversion we have ever gotten. Even better than the ones our company does

Every time I call Tony he gets me an appointment set right away and they always turn our trucks quickly so we can get them back for sale. They know their stuff!!

Exhalent service on our CNG fleet! Redmark fixed what no one else could, even FORD !! Great job!

Good service

Absolutely the worse customer service ever.
