Larry Ludwig
HomeownerMohrmann Electric installed generators for two of my friends and they both had only great things to say about them. I'm happy that I took their advice and used them to install my generator. Fred and the entire organization were most professional, knowledgeable and easy to work with. I'm in the real estate and construction business, which puts me in contact with many construction subcontractors, and I have never had a better experience with a trade professional. From start to finish they handled everything from the original permit application to the final sign-off. I would highly recommend them to anyone interested in purchasing and installing a standby generator.
