This is a great "peace of mind". The power went in my area once for four days and I wished I got this generator back then. This unit powers the whole house with no effort. Runs on natural gas and is very quiet. The person who installed it is fantastic, he said he will service it once a year just to make sure its running the right way. I tried it out for a week, just running the generator and I was very happy with the performance. I have a lot of equipment for the physically challenged and really need all electrical sources to run properly. I don't want to be stuck with out power.

I kept waiting for a power outage to see if the unit would cycle as it should and it performed perfectly when the outage happened. The unit is the required distance from the house and is barely noticeable when running. BTW: The installation was done by people that knew what they were doing in a very professional manner.

We have used our Gen 5 times since install. Sure save dragging out extension cords and gen to run septic pumps to pump down, then hook up ref & freezer to charge. The night they finished hooking up Gen we had to use it for 4.5 hrs. Sure glad we have it, worth the money.

I have 2 outagedes already and the system work great, when the power went out and come on. This was great the first one was around 4 hours and I am total Electric, TV worked Lights worked, refrig stay on & the heater stay working. Great system. I am proud I bought it and it was a easy installed and delivery. A Big Thank you

Very pleased with purchase of generator. Between Generac's website and the local dealer, I was able to pick the right one for my home business needs. I will say that not all dealers are "created equal" so be sure to get several quotes for the job. I got quotes from three different local dealers. Though the quotes were within range of each other, the process helped me pick the most professional and customer-service dealer. And that made all of the difference for a perfect and timely installation. About two weeks ago, we had a power outage which lasted 6 hours. The generator automatically switched on when it was supposed to. And then when the power returned, I barely noticed the switchback. What a marvelous experience!

This is our 2nd Generac . We have one for our cabana and now a new one for the house. Oklahoma winters can be very harsh with lots of icing occurring on power lines. For convenience, we added the second Generac for the house. This is a great reliable product.

I live in the Turks Islands. We lose power frequently and we considered buying a generator for years. Luckily i waited and purchased a gereac model. When we lose power the transition is almost unnoticeable. Within seconds the power is on. I have two central air conditioners, one split AC unit and all the normal household appliances. 22kw guardian seriesunit powers it all. The unit is very quiet too. Down side. When we lose power all my friends come over and empty my wine cellar

Actually, aside from it looking good, We have no idea how well it works. We have not had any type power outage since installation. Further, we have attempted to "be there" when the unit initiates its bi-weekly "process". As yet have we heard it start up. Therefore, we're unsure if it works. We've contacted the consultant and he checked the time & date and the schedule and pronounces it "good to go". so, at this time, we are in a "wait & see' mode.

We purchased the Generac 22 kw Guardian system in October of 2015. I installed it over the next several months as I had the time. A few months later we had a power outage for about 5 hours. When the power went off the Generac powered up in about 15 seconds. Wonderful! I am writing this review 2 hours after our power has been restored this morning January 25, 2017 at 8:45 am. We had a very bad ice storm on January 14, 2017 and thousands of people have been without power. Many still have no electricity as I write this. We gave this generator a very good 10 days and 9 hour workout. My wife and I highly recommend this generator.

We live off the beaten path in Midcoast Maine. After losing power several times, I did a lot of research on generators. I ended up purchasing the Generac. Less than a week after it was installed we had an ice storm. In under 15 seconds, EVERYTHING came back on. This is a quality generator that is a great value.
