Rated 5 out of 5 by Kcender from Peace of Mind We've had ours for nearly two years now and the power outages are becoming more routine here in northern Calif. If it isn't PG&E doing preemptive shutoffs due to winds, it's forest fires like the one we lived through here, just last week. Originally we were going to buy the air-cooled unit of the same output, but my electrician gave me a heads up on this liquid cooled unit and it has paid off for us. The lower dB level plus the extended maintenance schedule is a must when you are making power 24 hrs/day, multiple days in a row. This machine is built to take that duty cycle. We use propane and it can run into cost, but it is really cheap peace of mind for us and I have no regrets on buying this machine. Now my neighbor has the same model and he thanks me for educating him as well. Me too because his is just as quiet as mine.

Rated 5 out of 5 by Brooks from Quiet and Powerful After a great deal of research I settled on the liquid cooled 22kW natural gas powered generator. Quieter and longer lived. I also opted for the extended warranty as well. Very happy.

Rated 5 out of 5 by ctp56 from Performed flawlessly Had our 22 kw liquid cooled Protector QS installed 4 years ago. Don’t remember if we ever had any outages longer than a day or so. It has always run great. We got the true test during Hurricane Laura. We left the morning before the storm hit. It was nice to comeback to a home with minor damage and a generator running just like it was supposed to. All in all it ran for 7 days and never missed a beat. Thank you Generac for making such a quality product. FYI , scheduled maintenance was performed during the outage.

Rated 5 out of 5 by Bob from 7Years old and still going strong I've had my 27KW for over 7 years and it's still performing excellent. We have the annual maintenance with our generator installer (Reliable our of Deerfield FL) and I could not be happier. Two years ago, it ran for 10 days consecutive and never missed a beat! Highly recommend.

Rated 5 out of 5 by JohnT from Natural Gas 22KW I live in south Louisiana and have been plagued by un-reliable electrical power. It seems that most storms, of any size, disrupt the power and on average it will be out for a minimum of 6 to 8 hours. My area is usually the first to ho out and the very last to have power restored. My Generac 22KW QS unit works great. We have had 3 power outages in the past year, and the generac unit picked up and handled the load without any problem.

Rated 3 out of 5 by CharlieH from Not very "rain proof" for claiming it's a "rain proof enclosure". We had this generator installed at our new house summer 2019 running off a 500g LP tank that also supplies LP to appliances. Overall I enjoy the generator. It tests when it needs to. It is quiet which is why I chose this one over the air cooled. Being in country I didn't want to disturb neighbors and wildlife with the horrible loudness of the air cooled version. My biggest and only real issue is that although the enclosure says it is rain proof it is not. We had a moderate rain yesterday afternoon for about 20 minutes. Wanted to check on things, opened it up and the foundation was clearly wet. Water came in on both sides (door sides). Not enough for it to be standing but enough to still be wet. When I opened the side doors water also dripped down the insulation. I would think a simple "gutter" or lip above the doors would prevent that from happening. So simple I believe it to be an oversight. For the cost of these units I would, and do, expect it to be rain proof if it claims to be so. I also think adding a bug screen to the louvers would help stop bugs from making their hokme inside. I spray insecticide to prevent that but i shouldn't have to. With all that said I cannot decide if I can recommend this generator or not which is unfortunate because this was probably the most exciting aspect of the house-build I was looking forward to. Living with unreliable power durijg even minor storms in southern Texas I knew we needed more than a gas-powered generator to get us by during storms and hurricanes.

Rated 5 out of 5 by Reggie from Customer Support Chris Braughton came out immediately and explained the installation process along with an affordable maintenance plan. He also answered my questions about my generac. Very professional, and I'd recommend his service to anyone that owns a generac.
