Thank You! Rick & Dave finished the installation on our generator today and did a marvelous job, very efficient and neat, could not have asked for a better job.

Mike and AlexStafford Springs, CT

I want to thank you for your prompt service and all the folks who helped me, especially Dave and Dan who installed the unit. Thanks again.


Please extend my thanks to your entire team, this was a long project, you had to put up with a lot of questions from me and delays due to the gas contractors. Everyone I had contact with at O.J.Mann was courteous, professional and always provided the information or service requested. An A+ job. Thanks again.


The power went out again tonight, for inexplicable reasons, here in the south end of Danbury, and our Generac kicked in right away. One of your service people showed up in less than three hours after we called you, and now all is humming along perfectly.

OJ Mann installed a standby backup home generator for us. The service, responsiveness and professionalism is remarkable. They're some of the most friendly people I have worked with. They took the time to listen, didn't try to up sell me and obviously know their product line cold. I would recommend without reservation.

This dealer is great. OJ Mann installed and serviced our Generac since day One. About a year after we bought it and about a dozen power outages in which it performed flawlessly hurricane Irene hit. I was most impressed that during a hurricane outage across the entire state it was fixed so quickly and also that the warranty was honored!!!! There was no charge at all. I have since recommended them to everyone I can.

Don, I want to thank you for your suggestion to use the new outside flood lights. They are really wonderful and give bright white light. Our generator has been installed and approved by the town of Fairfield... and now I am waiting for a power outage. Your electricians were efficient and professional. Anyone who asked, I have used your company name for new installations. Thanks again.

Excellent work! Very impressed with the workmanship... very neat & tidy. The guys worked for 12 hours straight to get it all done! The final product looks really good. There was a bit of a wait, but it was on Generac's end due to the sudden spike in demand for generators. I would recommend OJ Mann to anyone who wants to install a back-up generator in their home.

OrlandoDanbury, CT

I want to thank both of you for an awesome customer experience. I have been in the customer service a long time and have not had service like this in a very long time. I kind of lost faith in most companies for how business is done these days. I am old enough to remember how it used to be (but I am not that old yet lol). The way Alec and Don handled this process was exceptional. My wife and I thank you very much. You will be hearing from us once we get the gas installed to the house. We can't thank you enough.

TonySouthington, CT

Service has always been first rate, including this time – May 31, 2017. Equipment is reliable and functions properly.

SticklerWoodbridge, CT

OJ Mann installed our Generac 20KW standby generator six years ago and they have serviced it twice annually on a service contract. They did quality installation work, and they have kept the generator running perfectly the whole time. Today, their serviceman, Lou, did our six month service. He was extremely professional and cleaned the entire generator, inside and out, so that it looks brand new! I highly recommend OJ Mann to anyone who wants a dealer who cares about the customer after the sale as much as before the sale!

PopPortland, CT

I had generator transfer switch interfaced with my home panel so I could easily use my generator. The work was done perfectly and at a fair price. Others quoted much more so I am very happy. Glad I met the owner for on site quote,he is very knowledgeable and a PRO.


OJ Mann installed our generator 4 years ago. The installation was done professionally and we were given fair and objective advice when selecting the proper equipment for our needs.

We recently had an upgrade done to our standby panel, along with a routine service. Their service tech, Rich came right on time and completed the job in a courteous and professional manner.

We would strongly recommend this dealer.

BarryRiverside, CT

Our experience with O.J. Mann has been positive from day one to today (5+yrs later). Before they finalized our purchase, they did a site visit. They recommended a more efficient model that has performed flawlessly for the past 5+ yrs.

The installation was done flawlessly and on time. They thoroughly tested the unit before the delivery was completed. In addition, O.J. Mann has serviced our unit twice a year.

Every contact we have had with O.J. Mann has been friendly, Professional and exceed our expectations. Based on experiences, without hesitation we recommend O.J. Mann for design/install and long-term service.
