So far the unit hasn't been necessary. It comes on automatically for it's weekly 5 minute run. Starts right up and shuts down afterwards. It is a lot quieter than I I expected, like a lawn mower as others have mentioned. Installation was straight forward, the contractors knew exactly what they were doing. Wiring through our attic was iffy because it is so flat up there but they managed. So glad we went ahead and bought it. Feel so much more secure.

So far this has been a good investment. Thankfully we have not had to utilize it. It self tests every Monday and appears to be working fine. At least wedon't have to worry anymore about losing power for days on end. Glad we haven't had to use it yet extremely elated that it is available if a need arrives.

The Generac 22K whole house generator and switch gear is a reliable unit and was given good references by the electrical contractor that I sourced and installed it though. It is a little noisier than what I was told and I have had to let the neighbors know that they will likely hear it exercise running weekly. It could be muffled down more with a few additional low cost sound reduction improvements.

We had just had it installed several days before a hurricane. It was wonderful to have the secure feeling of having power to our home!! It worked great for the 3 days that we did not have power. It has also come on again about a month ago. We didn't even know our power had gone off due to a cut line in our neighborhood. It is a blessing to us!!

Nice generator. The Generac concrete pad is a must in my opinion. Also the generator base trim piece. With both of these options, we are VERY pleased with our unit. A very clean look that Generac has come up with. Not the least bit sorry for purchasing Generac! Should have done it years ago.

Power went out for 3 days after the install of our generac generator....ran continuous with no problems....convenience was exceptional of not having to manually start..powered the house with ability to do laundry, dishs and live life as if the power never went out. i highly recommend if you have power outages.....

We live in a rural area which is prone to power interruptions, so we felt we needed to have backup power generation capability. After comparing several alternatives, we chose Generac. Installation went smoothly, and the technicians explained everything we needed to know about the system in detail. Since then, our power has gone out twice. Both times, the Generac unit automatically started up, and provided power as advertised. The automatic transition back to commercial power and generator shutdown went smoothly. We are very satisfied with our decision to go with Generac, and highly recommend the system to anyone who needs backup power capability.

I am a little uncertain about the product for now. When they came to start it the motor would run fine but it would not generate any electricity. They now have to call the manufacturer and see what the problem is. They have installed a lot of these and say it is the first to do this. I hope it is something small. I believe once the get it working I will be pleased with it.

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.

My unit was installed in March 2016. Other than the weekly exercise period, there have only been a few times when the generator kicked in due to loss of power. There has been no problem with almost immediate replacement of power. There has been no failure to kick in. I'm very satisfied and happy with my purchase and dealer/installer.
