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.

Now we have peace of mind in a storm

We bought our Stand by Generator recently and we are delighted with our purchase. I don't have to dread dragging my walker over the extension cords in the floor when the power is off. Now we simply go on as usual after a few seconds. Thank you Generac and Mr. Allen of Allen Residential Electrical for giving us peace of mind in stormy weather.

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.

Runs quieter and has great App features.

We bought this 24KW four months ago and was only able to get it installed a month ago. So far we're very pleased with it. We bought a 22KW Generac 20 years ago and got a lot of usage out of it in south Louisiana. Back then it was referred to as a "whole house generator" but we soon learned that didn't mean you could run "everything" in the house on it. It running under a load because of a power outage and my wife was running the clothes washer, dryer, microwave, the electric oven and all the lights at the same time and it handling the load just fine until our 3.5 ton AC kicked on and it started to bog down badly. Lesson learned!! We have only used this one in the exercise schedule and not under a load yet. It is quieter than our old one though. Be sure to get the App for it if you want a more detailed status of it and setup an exercise schedule.

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.

No more power worries

I just had this whole house generator installed to my delight. It works seamlessly with household with low noise level. I can run everything in my household without interruption. The only difficulty was using their APP since we are not very Teck savvy.

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.

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.

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.

It comes on when power goes out.

Had 15 different power outages in the last 12 months and some outages lasted days. We have had no power outages yet sense we bought and installed the Generac generator. Now when storms come I'm not worried about power loss but I am scared of tornadoes.
