Best Testing in Columbus OH

Two very professional technicians came to troubleshoot a problem related to an outside light above the garage. I really appreciate the expertise, dedication and determination they displayed as they worked to solve the problem. They answered my questions clearly and concisely. They provided me with an estimate for additional work, and explained the details. I won't hesitate to request them again.

Daniel responded to my text and showed up shortly after. He diagnosed the issue (that was missed by a previous electrician) within a few minutes, replaced a part, and brought power back to our lives!
He was so friendly and knowledgeable. He talked us through exactly what the problem was and how he would fix it. Couldn't be happier.

Excellent service hands down! Ken has a really great personality and he's definitely a subject matter expert. He was able to accommodate a scheduling conflict with professionalism and a timeliness turnaround. I'm a happy customer and I approve this message! ?

Had a great experience with this company.

Great place and super fair pricing. Tremendous skill and honesty here!
