New Gen

Just got this 26KW installed and operational today. We are happy with the test that was done with it and hope will all luck that this will never have to be used, but we have lost many a refrigerator/freezers over time and in our new house we refuse to submit and surrender to mother nature and her moods. We are betting on this 26KW to do her job when called into action.

Finally!!!!

Finally had my Generac installed today. Installers were great, basically working in a monsoon. Very professional, very detailed work, left no mess. You could see pride in their work. Now my mind is more at ease. Thank you Shepp Electric of Chardon!!!!

A Very Good Value and Investment

We have had our generator for a month and only had to use it once for five minutes during a brief lightning storm. It performed as expected. The engine noise is somewhat louder than I expected but is not an annoyance. Having this generator has given us much needed peace of mind. An investment that is truly worth the money and value.

Constant maintenance issues

We have had this back up generator for about five years now. We have had scheduled maintenance done every year by Genstar and every year we have some sort of major problem. For the second time in a year and a half, all the oil has leaked out of the generator. The first time was from a pressure switch that went bad. I have not identified the source of the second leak. We’ve also had to replace the entire control panel and another electronic module. We have a severely brain damaged daughter who relies on electricity to power her ventilator, feeding pump, oxygen maker and pulmonary suction machine. We need something more reliable. We have spent about 40% of the cost of the generator in maintenance and repair repairs already in a relatively short amount of time.

Outstanding customer service.

Recently installed 22K generator on new residential construction and finalized hookup with electrician and plumber on July 1. When I asked if they were going to get it set up they both said they just install their part and said to call Generac. I called customer support this morning, July 2 and when I told this wonderful lady what I needed, she said we can do this over the phone. We registered the unit and she was very professional in getting the information and where to find it. I then went outside to the generator and she walked me thru the set up in a matter of minutes. She then reminded me if I need anything else, we're here for you 24/7. What a great experience and greater customer service. Hats off to Generac for this outstanding customer service representative.

Nice generator set

The generator is good, I do wish the generator and the transfer switch were painted the same color. I know its minor, but it bothers me. The gray color of the transfer switch blends in well with my house siding. I have my generator installed near my a/c units and they are all gray, but the generator itself stands out with its beige/tan color. I also with it could be a little more quiet and the sound proofing on the generator lid does'nt stay in place very well. Every time I open the top cover the sound proofing has fallen down.

Great generator and great family peace of mind

Installed the 22kw whole house transfer switch generator at the completion of the construction of our new home. First time having a system like this to keep the power on. It sure adds happiness to our family living in Florida where high humidity and high temperatures during Hurricanes when the power is out will keep us comfortable.

Keeps Our Home Going

After being without electricity for 11 straight days with hurricane Laure and then 3 days with a ice storm 5 months later we decided to get the 22kw home generator with the ATS switch. During Laura I poured 353 gallons of gas for our 15kw portable generator. That is not a type o. Since our purchase 17 months ago we have lost power three times and each time the generator has worked flawlessly. No more having to come home and hooking up the portable generator or hauling gas.

Excellent purchase

We are very pleased with the company that did the installation. They arrived on time after having ensured via phone that the order was in line with what we wanted. The installation team explained all aspects of the installation and the ongoing use/maintenance of the system. Work was completed in a timely fashion.

Excellant Product

We recently had the Generac 22kw installed. We are very pleased with the looks and quality of the Generac. We did shop around and felt it was the best product available. We also liked that we were able to buy the optional Generac pad, made especially for the the Generac, to keep it level. It runs very quiet considering it is an engine. We like that it starts up once a week to keep it in good running condition. With a member of the household having health issues it is wonderful not to have to worry about not having power. The installers were great and we like being on the e-mail list for more information. We referred the Generac to a friend and they also purchased one.
