Norman was the tech that came out. Came right out quickly I might add. He fixed the problem in just a few minutes. Said it was an EZ fix and no charges. Wonderful service.

They did good work, my only complaint was that they didn't show up with a clear plan of how they wanted to do things so we could have things already moved out of the way and ready, so we had to reschedule for the next week.
