why choose us

Jeff and Mike Addair's dedication and commitment to these core competencies led Diesel PowerHouse to becoming one of the area’s most respected diesel fuel injection service centers in Northeast Florida.


Providing services to both consumers and businesses, the company started in Callahan, Florida, just north of Jacksonville, Florida off US1. The company's 12,000-square-foot facility was designed to accommodate a full service repair shop with the industry's most advanced diagnostic and testing equipment as well as service bays allow Diesel PowerHouse to accept any type of diesel powered vehicle for "Drive Up Service."

"It's not uncommon for service trucks to roll up at any time of the day. Even contractors who are having a problem with a bulldozer or backhoe might trailer it right up to the service bay," said Jeff Addair.

With the nation’s focus on "Green" technologies, fuel efficiency and of course performance, Diesel PowerHouse has been uniquely positioned for growth over the last decade. The company's success has led to many new job opportunities for area diesel technicians and an expansion of its original 4,000-square-foot facility to over 12,000-square-feet in 2010.

We believe the success of our firm is directly attributed to the professionalism and service excellence we extend to every customer, our commitment to sticking to what we know best by focusing on our core competencies and the integrity to recommend exactly what you need to get back on the road as cost effectively as possible without cutting corners.

If you’re having performance issues with your truck or SUV, industrial equipment or any other diesel engine powered equipment: we can help.
