This is my second Generac whole stand by generator. I bought in 2016 and the new one as it has the aluminum housing and it has 5K more power, even I really did not need the extra power. I bought the extended warranty. So far it works just fine – we have only one outage and that lasted about 6 hours. I live in the Houston area and the time we really need a generator are hurricane type events and those can keep the areas powerless for up to three weeks. Before I bought my current home, the neighbors reported to me with we had hurricane Ike in 2008, they were without power for over two weeks. As long a BIG tree does not fall on the unit, I am ready for the next one.

Mine has worked exactly as I had hoped it would. That is, it only turns it's on Saturday at 2pm to perform its weekly check... Haven't had any power outages yet requiring its service but it has given me a comfort level knowing it will come on and my home will be powered since I have a disabled son here 24 hours per day.

Thankfully,we have not had a power loss yet. But it's working.Every Friday at the exact minute it runs through it's test for 5 mins.to the second,then shuts down. It's given us great confidence that it will be there when needed. And already gave recommendations to family and friends. 22KW Guardian

this unit was a replacement for a 18kw generac , it only lasted for less than 500 hours less than 8 years old. current one 22kw on its first weekend run, it started to have a slight surge. found the air filter had to much fire retardant on it changed out for new now its ok. hope this one lasts longer!

We live 1 1/2 miles from the highway on a dirt road. In 1995 when Opal came through, we were without power for a week. Now that we are older, as bad as that was then, it would be a very bad imposition now. With our generator, we can keep the entire house going now and don't have to worrying about power outages.

One of those items one hopes will never need, but wish you had when needed! Was put into action a few days ago during a storm- was completely seamless in terms of activation and performance of required tasks. Quiet, efficient, with no running back and forth to obtain fuel, etc. In summary entire family is glad we have a dependable source of power if needed.

Great investment. Having heat and an elevated sense of security during inclimate weather has put us at ease. At first, the cost may be a little frightening, but you won't be disappointed in the purchase when you are warm and safe in your home, when others aren't so fortunate.

This was our first purchase with Generac and couldn't be any happier with the entire process. From answering questions about the products to receiving delivery, it couldn't have been any smoother. Great value for the price! Generac staff were very helpful and professional!

I upgraded to the 22K size to do my whole house. The smaller sizes would only do part of the house but the price difference wasn't too big. Overall, I do feel the price was too high but part of the reason is the installer had to come from the big city to my small mountain community. In less than a year since installation there have been several power outages, some lasting many hours. The unit has worked flawlessly and my whole house runs normally, with only a 30-second delay while the generator turns itself on automatically. My only complaint is the remote monitoring offered by Generac, at quite a high price. It doesn't have enough features or control capabilities, and I couldn't find a 3rd party monitoring solution that would work better without spending many more hundreds of dollars. I would reluctantly pay the Generac high price for monitoring if their system had better functionality. Now i no longer dread the inevitable power outages and I would recommend the 22K Generac.

I had this Generator installed about 4 months ago. The power failed only once since then and the Generator kicked in within 10 seconds. We hardly noticed the power failure. If this Generator continues to work like this (with proper maintenance) for the next 10 years--I will consider this as an outstanding investment. So far so good.
