Customer Testimonials:

"We contact Square One to see what they could offer. From the first component we sent them we saw a drastic improvement in the quality of analysis that was done on the components. Through their analysis of the failure modes, we are able to implement counter measures that are helping to prevent the same failures from happening again. All rebuilds cone in at or better than new condition with detailed spec sheets on what was done. We are extremely satisfied with the service that Square One is providing for us."

Our experience with Square One confirms to us that we've chosen to align ourselves with a reputable service company." - Fred / Solvay Solexis, inc.

"The reason I like Square One is the after hours service. One night I had a motor on one of our main air handlers burn up. I called the after hours number and got a return call in minutes. They did not have the motor I needed in stock but opened the distributor in the middle of the night and delivered the motor in a couple of hours. Great customer service." - Ron / Terumo Medical
