Great reliability.

We have a peace of mind knowing in the event of an outage our electricity needs will be met. One major concern is that the politicians believe future electric demands can be met solely with green energy. I worked in electric production for 30 years and I know that will not be possible.

Satisfying to spend money on a great product.

Within ten days of the initial startup, we had our first power outage on Memorial Day afternoon. within ten seconds or so, our whole house was up and running on our new unit. It was a great feeling. A/C up and running, everything. It gave us a great feeling.

Perfect for what we need.

Purchased a year and a half ago. Have had it kick in and run twice for about half a day each. As well as test running it has been very reliable! My wife and I are getting on in years and I have developed major health issues. Last major power outage was during Fiona and I was without electricity for a month. We have many medical items to assist us and are crucial. Was running for gas every day and waiting in line like everyone else, as well as trying to find open streets while the power crews tried to restore power. So finally said that this is enough and we are going to get a full house power unit and enough propane fuel to last a month. Feel the power situation isn't going to get any better soon.

Security in the Storm

I bought this a year ago and didn't get the chance to use it until this spring - several times! The sense of security it gives me when the storms hit is priceless. I used to use a portable generator but the auto-pilot of my GENERAC saves time - and potential property damage. I have a sump pump and having it connected to this generator is worth it, besides all my other appliances !!

We've had it for a month, and I would have bought it way sooner had I realized how much comfort there is in just knowing it's there. We don't lose power here, but I DID stress every time they predict freezing rain, and we did fill buckets of water in the bathtub for toilet flushing every time they predicted bad weather. Now I can forget that stuff and just enjoy life. That's priceless.

Features are okay. I just need it to run.

The unit threw a rod in January of 2025 and threw 2 more rods in 2026 with a sum total of 115.5 hours of run time. I can see a unit going down once and being repaired, but twice for the same thing, even Generac should recognize there was and is a problem. Generac finally fixed it but after months of waiting. I would not recommend a Generac to my worst enemy because of Generac's reluctance to make it right.

Love my Generac

I had this unit installed last year. I am so glad I did, and as a widow, it has removed a lot of my stress when the electricity goes out. My knowing that the Generac unit will come on in a few seconds is such a comfort to me. It will run the whole house, lights, A/C or furnace, appliances and the garage door.

A great Investment!

I purchased this 1 year ago and could not be more pleased. My wife and I both work from home. So, power outages which are becoming more frequent are disruptive. It's large enough to power our entire home. And the cutover is pretty seamless. We also have cellular backup for internet connectivity which is a super-solid combination.

Outstanding reliability and performance

A little over a year and several long power outages, this thing has performed flawlessly. There are 2 homes in our area that stay lit up during an outage, my mom's and mine. It was comforting to see her Christmas lights on when the neighborhood was dark.

Time saving, great device!

My wife t thought I was crazy for buying a stand-by generator because we have a generator that I double hook up to run a few things in the house. Now since we have the generac she sees how handy it is and I don't have to go outside in the freezing cold or rain in order to "hook up" the other one!
