Verified Purchase

Great pick

Had it for 7 months and no issues so far, the unit routinely tests itself with no issues. Not much to say on the appearance it kind is what it is but we put bushes around it to cover it up

Good Product, But Very Expensive

The only concern was that the installer had difficulty setting up the weekly Exercising. After three attempts, this was corrected and is now working correctly.

I purchased this to replace previously installed unit which was over 20 years old. (Still working perfectly) Case was rusted. New one works perfectly, however WiFi could use improvement.

Never be with out

We have 2 homes. One is a small ranch in the country that has 10 other people on the power leg. It is not uncommon to have power outages frequently. During an ice storm power was out for 2 weeks. Not mine! The other home is a lake home which also takes a long time for power to return to normal. Bottom line is we will not have home with out a generator. We use the 22K on propane. The ranch has 2 large a/c units, 2 upright freezers and 2 refrigerators. The generator runs the whole house just fine.

Generac Generator

In my previous residence, I installed a Generac generator, and its reliability has consistently been exceptional. Furthermore, the maintenance process is straightforward and hassle-free. I have encountered no issues whatsoever with the Generac generator, making it a highly recommended investment.

Generac and Robbie's (dealer) Support

This is my second 14K generator, first lasted 15 years. Replacement done less than 24 months ago. Little over 1 month ago, new unit's engine died. It blew oil , smoke, and even the oil dip stick. Dealer replaced new Generac engine, after going through protocol with Generac. This was within 2 weeks of engine failure. New engine just ran for 61.5 hours during major blizzard!!

Thankful

I'm so thankful I purchased this generator my daughter had been wanting me to buy one for a few years . Me being afraid to step out on faith thinking we couldn't afford one. So we prayed about it God heard our prayers and sent the right salesmen to talk to us about it. I almost called him and told him not to come but a small voice dropped into my spirit and said just listen to what he has to say and the rest was history.. so thankful I listened and didn't make that call to not come and tell me about this generator... We are so thankful and it's at a price that we can pay without a struggle... Yes God will always get the glory from us. . GREAT INVESTMENT to our home. Thank you all so very kindly. Rita & Tyra..🙏 for all.

New and improved version

Just installed and completed and we have no issues. Had to leave our first Generac at the old house and now have the new and improved version. The simplicity of managing is great, have recommended to our neighbors and they are being installed and ordered as I type.

Works great when not triggering error messages

This is my second home with a generac and I am very disappointed in the new unit on my current home. It keeps encountering errors after it starts running which defeats the purpose of having a generator. It's terribly disappointing to spend so much money to prevent energy outage at our home/business, but with no better outcome than others that have not installed a generac. I truly hope that this software issue with our new generator will be resolved soon by generac.

Very professional and informative.

Installation was very smooth as the electricians and plumber know this product inside and out. They were courteous and professional and answered any question I through at them. They went though how to manually start, transfer and test the unit as well as the app. The generator it self has a very clean look and is quieter than I imagined. K&B Energy out of Livonia Michigan. I highly Recommend this company. They were not the cheapest and it was scheduled about a month out, but let's be honest… you want a busy contractor: they're busy because they do good work. You don't want the cheapest: why/how can a company be cheaper than others? Because they don't do good enough work to get enough work. K&B was the smart choice for me.
