Jose, was here today to do preventive maintenance and he appears to be very knowledgeable regarding his craft.

Installed a whole house generator for us a few years ago and everything has been working great. Signed up with them to do the maintenance and everything has been running smoothly. Install was pretty easy going. They handled all the permits with our village and it all went smooth. Prices are reasonable as well. read more

I have an older Generac generator. It stopped working. I had TWO other electrical companies come to repair who also claim to fix Generac generators and had no idea what they were doing. First guy was face timing his boss. Told me to order the control board off Amazon which I did and then thought about that and returned it. Looked under the hood after he left and the guy had screws all over and I saw that he broke one of the battery connectors. Cancelled them coming back. Next electrician said he would come back in a few days and thought it was the starter. That was three weeks ago. Had Mohrmann come today and within 15 minutes the generator was working. They replaced the two battery connectors and battery. That's all we needed. To think two other companies who say they "specialize in generator repair" had no idea what they were doing. Thank you Dennis Mohrmann. I will recommend you to everyone as you came with a fully stocked truck, professional demeanor and knowledge you were willing to share with me about what you were doing and what was wrong. You are a fabulous diagnostician and electrician. read more

First of all let me start by saying that this is the worst most unprofessional company, you could ever deal with, if there was someway I could have given them zero stars I would have, they only want to sell you service, I have been using them for regular maintenance on my standby generator for years, I received a letter from them stating that they wanted to provide us with a regular maintenance service which I allowed them to do, today we had a horrible storm I tried calling them for two hours , it went straight to voice mail, finally someone picks up I tell her my generator that just had been serviced and was working fine is now not working, She tells me that she has no idea when someone will be able to come for service, not for at least 2-3 days, when I start to talk this very nasty lady has the audacity to hang up on me, I am so outraged by this I go down to their office to see if I could speak to someone perhaps the owner, I am treated with the same disrespect, The owner was there, a much much older man who did not at all seem to care one bit about the way I was treated, this company is run by one old man and two nasty old ladies, if you are looking to get any type of service I would stay away from this company, I don't usually write yelp reviews, but I really wish I myself would have been warned before I started doing business with this company. It's nice to know when you deal with a company and you need them they'll be there for you, sadly to say this is not the case with this company. read more

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!! read more

If it was possible to give this company a negative review I would. Horrible service. Had to deal with a rude employee that really put a bad taste in my mouth. Do NOT use them, trust me read more

I use Mohrmann Electric to service my generator yearly. Today was the first time I used them for an electric project. The quote was more than reasonable. The office staff was responsive when scheduling my appointment. Chris, the electrician was the best! He was on time, courteous, extremely knowledgeable and professional. He is an asset to their company. I would definitely use Mohrmann again! Thanks again Fred and Chris! read more

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. read more

They could not have been easier to work with and fairly priced! They did all the permits and everything for our generator, and were super professional walked us through the whole process, made sure they called to let us know each step when we needed someone home worked with our schedule. Our generator is fantastic! They did an amazing job right within budget I highly recommend them! read more
