Great experience all around! They were prompt and repaired my generator before i signed the service contract! Wonderful to do business with!
Installed a gas generator for our home about 2 years ago and they were great to work with and reasonable with pricing. Would definitely recommend. I am also doing the maintenance with them and everything has been good so far.

I would highly recommend Fred for a Generac standby generator. He was competitively priced and his crew did a great installation job. Whenever I have a question, Fred or Laura respond promptly. Chris their service technician is a pleasure to work with. I got estimates from a number of firms and I am very happy we went with Fred. Thanks Jay W.
Installation of a turn key 14 Kilowatt standby back up generator. Including filing of permits and permit fees, a two foot elevated masonry platform, 14 Kw generator, automatic transfer switch, all wiring, plumbing for the gas line, gas meter upgrade, 5 year warranty, Gen Link, one year of maintenance. I met with Fred Mohrmann, the President of Mohrmann Electric Company in May 2014. Fred proposed a 14 Kw system, and bid a very competitive price. By the middle of June 2014 Dennis two additional electricians delivered the unit and begun the installation. In addition to the generator installation Dennis replaced my outdoor light with a customer supplied light with motion detection. At the end of the day the crew did proper clean up. After the generation was installed the contractor had a plumber from JLM Plumbing & Heating install a gas line to the generator, and add a meter upgrade. This too went very well. On July 3 the installer returned to activate my generator. All went well. Twice a year a technician from Mohrmann Electric performs an inspection and maintenance onsite. The service people are highly qualified and take the time to do the job correctly.
