Stay away from this company. We been using this company to service our generator and it was not the best experience. They promise great support and same day support, but its never the case. They only work around their schedule. We had outages many times and they never came when it was needed. It was always after when the outage was fixed. My most recent experience was too much to hamdle. Our generator for some reason was not turning on, I called them to come take a look, after a few weeks, they finally came.

They never called me to let me know what they did. After many calls I and no return calls, I received an estimate to replace the entire controller and relay and replace the battery too. They wanted to charge me over $2570.85. Luckily I called another company to check. The other company had the generator up and running in no time. They said we did not need a new controller or new relay. Of course I was upset and I emailed the previous company to stay away and to cancel my contract. Who knows how many other hard working families they did this too, I will be reporting them to local authorities and towns. Pissed off customer. Stay away.

This outfit serviced my generator for a number of years (since it was new) and I have not been impressed. I find their communication very poor, their phone system does not even have the capacity to take messages after a storm event (insufficient volume). I don''t fault them for not having the surge capacity to service all their clients after a storm, but I do have concerns about their expertise and practices based upon a few of my interactions. The last experience forced me to go elsewhere. These things are expensive. Go with the best outfit you can find. I don't recommend these guys!

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.

I can't say enough great things about Mohrmann Electric! It started when Fred came to give me an estimate for a generator. He was so thorough, professional and considerate. I felt very confident after he left my house. Everyone that I dealt with could not be nicer or more helpful...Judy and Laura in the office who really walked me through the whole process and kept me up to date, Juan who did all the electrical work, and Dennis and Brandon who set up the generator and came to do the start up.

I wasn't home when other work was being done so I can't mention their names. My home was always left in perfect condition. Since I needed a gas meter upgrade the new meter is much larger and no longer fit behind the sliding doors I have in my finished basement but Fred told me not to worry because they would take care of. Fred was right because Dennis and Brandon rebuilt the closet beautifully! (Sorry again about the sandwich Dennis!!) I'll always use Mohrmann Electric from now on for anything electrical. I just love hearing my generator do the weekly checkup every Sunday! Thank you Thank you Mohrmann Electric!!
