Weekly test runs are going fine: starts on time and idles low after a short run at full speed (so it is much quieter). First power outage and the transfer switch, generator and power supply started, ran and shut off seamlessly. Impressive. The only improvement would be if it were not that loud: can be heard clearly in the house and even might affect level of speaking or certainly could affect getting to sleep.

This is my second 14K generator, first lasted 15 years. Replacement done less than 24 months ago. Little over 1 month ago, new unit’s engine died. It blew oil , smoke, and even the oil dip stick. Dealer replaced new Generac engine, after going through protocol with Generac. This was within 2 weeks of engine failure. New engine just ran for 61.5 hours during major blizzard!!

We purchased it about 2 years ago and it pretty much has failed us when the need arises during storms or other weather in climate conditions. This was bought because I have a cpap machine and need it to sleep. Also to protect the contents of our freezer and fridge.

We had a bad thunderstorm yesterday and lost power for a couple of hours. Our generator came on and worked perfectly. We would not have known the power was off and the generator had taken over if it had been for us hearing the generator running and the light blinking. I gave a 5 star rating because of the way the generator has performed even though I am still not happy about being put off about the damages,

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.

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.

I bought this a few weeks ago, already storms have gone through on two different occasions and knocked out our power. The generator has preformed flawlessly on both occasions, running for approximately 23 hours total for both occasions. My neighbors are jealous

Our Generac was installed new, at the end of February and we are really excited to have it. Although the power has not failed as of yet we feel more secure having the backup/emergency power. I have been disabled for 10 years now and having to lug around a portable generator only to run a fridge and furnace fan was getting very hard to manage for me. Now I can sleep a lot better knowing all that and more will be working as it should when commercial power is not available.

I bought this last year when Michigan was out of power; yes, practically the entire state was out because of a massive ice storm. I was without power for 3 days, called the Genarac dealer and they installed the next day. There was a small problem, they installed the wrong size generator (18KW instead of the 22) but, because it was an emergency, they installed, but didn't bury the lines and set in the ground. They came back after the ice storm and replaced and reset. It runs for 5 minutes every Saturday. Good thing, a year later, another ice storm. Power went out and I didn't even know it. I woke up to everything running, including my robot vacuum. Wasn't till about 1/2 hour later that I realized the generator was running. My only complaint, after about 24 hours, I could smell gas (propane) in my house. I didn't know if it was just the fumes from the generator or if I had a gas leak from ice. But once the generator shut off, the smell went away. So, I guess it was just fumes.

If you are familiar with the Electrical and Gas Codes you will find this very easy to install. This family of Generac Generators is very reliable and convenient. It offers a great deal of confidence that your home and family are protected during emergencies.
