I live north of Buffalo, NY and we get some wild weather. 20+ years ago I had a 13kw partial home Generac generator installed I never had an issue with its operation for 2 decades. Due the age of the 13kw and hours I had on the unit - I added a manual hour meter; it was time for an upgrade. I chose the 18kw whole house with external whole house transfer switch. The dealer arrived with 2 installers and 3 electricians and knocked out the replacement installation in about 6 hours which was remarkab...

Reliable backup
If the power goes off during a storm it is sure nice sitting in the dark for 20 to 30 seconds and then the Generac fires up and our whole house power is back on. The only way to tell when the hydro power is back on is when the Generac shuts off without any interuption of power.

So Relieved and Happy
Running now for a year. We have had power outages while away. It was great not worrying about the basement flooding. We have also had a couple long term outages and it's nice not having to pull out our gas one and set it up. We didn't go for the whole home. We have our furnace, well, sump pump, septic, freezer room, kitchen fridge and some outlets. We also have my aquariums running on a circuit. Well worth the money

To soon to tell.
Fortunately, I have not needed to use it yet. It has been hooked up for three weeks now. It runs every week on its scheduled start time. But, I can’t rate how well it works as a true backup since I have not yet needed it.

Mostly happy
Bought this a year ago, we are happy with the system itself but not with the company who installed it, we were pushed to buy it and then their follow up has been no contact at all, they got their money so they don't care

Great dependable generator.
I’ve had Generac generators for over 30 years. Very dependable with little maintenance. They last for a very long time. I have so much peace of mind knowing my home will always have power.

26 kw generator
It’s about two years old . I have done the maintenance myself using generic oil and filters spark plugs and air filters no aftermarket products and it ran 8 days and nights this past January during the worst ice storm I have ever been through it ran everything flawlessly

Keeps me breathing
I am on oxygen 24/7 , and , my generac has saved me from relying on oxygen tanks. Although , we have had a couple of minor setbacks where the generator failed. Our local certified generac service team " GEN ONE" had us up and running quickly.

Ready when!
I've owned this unit for over a year now and it was purchased through Costco. It has kept the power on a few times for short outages, without fail. No hurricanes yet and hopefully we won't have any, but, I'm ready if when we do.
