Because of our buying power, we offer price breaks on parts and on average we charge 30% less than our competitors labor rates. Dealerships typically charge labor rates of $140/hour vs. our $110/hour rate.

Our Services


24/7 Indoor Testing Facility

This may not seem like a huge bonus at first glance, but bringing our entire testing operation indoors means we can work on your heavy equipment repairs longer and get them completed faster. No frozen pipes, no weather delays, and maximized repair and replacement efficiency. Did we mention we can test up to five pieces of equipment at one time?
