I had some people come to install an AC unit, a Mitsubishi, for a condo. I worked mostly with the AC company but there was one part of it, a 220 hook-up, that they weren't licensed to do the work on so I think they hired Mr. Electric to take care of that part. They did an excellent job. The hook-up passed inspection, so they must have done it right! I'd have no reason not to give them 5 stars.
