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.

Has Never Worked - multiple faults and service

Installed two months - 1 power outage - unit failed. dealer has been out 8-10x. new motor, new wiring harness. every sensor has displayed multiple faults. total piece of junk. I have had a green mobile link status 2 days out of 2 months. At this point Generac should be refunding me my money and removing this unit! it has never worked. think there are serious electrical / computer issues with this brand. all my neighbors that have generac told me it took several months to get them sorted.

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.

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.

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.

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.

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!!

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.

Peace of Mind and Reliable

Having experienced "Snowmageddon" in North Dallas a few years ago and without power backup, this new Generac whole home generator brings incredible peace of mind. It's good to know it is always there ready to take over should the power grid go down. The only reason I gave it a 4-rating is because of the delay between power failure and the generator starting. I wanted Tesla's system mainly because of its ability to take over within milliseconds of losing power unlike Generac. If power is out for more than a second, then there are several clocks that have to be reset. I've had days when the power blinked multiple times thereby requiring clock resetting each time. Very annoying. If Generac would develop a battery unit to incorporate with the generator that would bridge the gap between the grid failing and the generator taking over, then I would definitely give it a 5-star rating. That's my only complaint, and it really isn't a Generac fault since it operates as designed. I just wish the design would change a tad to eliminate the time gap.

Fantastic insurance for inconvenience

At my age of 67, I am glad to finally get an install a Generac standby generator. Even if the power just goes out for a few hours, it will be much easier to put up with the inconvenience. Basically there won’t be an inconvenience. I believe standby generators are worth every penny.
