We love our Generac!

We had our Generac installed during the winter. The process was handled with care and patience. We have family and friends with Generac home generators and we heard nothing but good things about them. The generator is turned on remotely once a week to make sure everything works properly. It’s so good to hear it running and to know it’s ready at a moments notice.

Just do it

I was hesitant to purchase this at first. My wife insisted that we do. Since purchase we have had 2 major storms and the Generac has performed flawlessly. The whole valley was without power for 2 days and we were eating popcorn and watching Netflix. I will say that we can hear it running when it comes on, but it's a small price to pay for comfort.

Don’t Waste Your Money - Buy A Different Brand

I bought this generator and installation was attempted by a Generac “Elite” dealer and installer. Now, 3 weeks later, and after multiple attempts by the installer, IT STILL DOES NOT WORK! There are battery charging error codes and fuel delivery error codes. If it comes on during the weekly self test it shuts off after 4 minutes, the warning light turns red and it sends a warning that it won’t restart in an emergency. Don’t waste your money buying a Generac 22KW whole house standby generator. Look at other brands that actually work .

Seamlessly continues power supply.

I bought this unit for a rental tiny home on my property. I had already installed a 17kv Generac which services the main house. We have electrical outages several times per year in our rural location and our Generacs work flawlessly to seamlessly continue to provide power when this occurs.

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.

Saved our sanity!

Bought this over the winter and have already lost power for three days. Generac saved our food in freezers and fridges. Last year we lost everything. Like the AP so if you are away from home you can see it if it is running. Also since we are on a well, Generac kept the water running! Lights, water, kitchen, wifi all good.

Not working to specification.

Been over a month and I have no resolution to an Engine Speed Alarm/Fault that renders the system to not initiate automatically as designed when my power goes out. Without this key feature operating correctly I feel dissatisfied. No eta has been provided for a fix which adds to my frustration.

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.

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!!
