Rated 4.8 out of 5 by 12reviewers.
Rated 4 out of 5 by Generac was the mostly widely recommeded Spent quite a bit of time researching which generator to purchase before deciding on the Guardian 22kw. Read tons of reviews on all products and even when there was an issue with the Generac it was always quickly resolved. Brings a lot of peace of mind just knowing it is there the next time a storm threatens a power outage. January 28, 2015
Rated 5 out of 5 by Great generator I have been having my 20 kw Generac generator for 20 years. Great product and very reliable. I use it for Katrina in Louisiana for 18 days 24/7. Never had any problems. November 19, 2014
Rated 5 out of 5 by Excellent product & dependability We live on the Gulf Coast (near hurricane ally) and purchased the 22kw LP Quitesource. This unit will run everything in my house, A/C, oven, water heater, everything at once, including lights for my neighbor's house. We purchased a liquid cooled unit for it's continous running ability and it is reportedly quiter, but I now believe an air cooled unit would have been fine. The generator is about 80' from our house behind a small shop. If we are on the porch when it does it's weekly maintenance run it's as quite as a small truck would be at 80' and unless you're tuned in to listening for the generator you can not hear it run from inside the house. And cheap on LP consumption, the unit has been in service for 2 years, it runs 15 minutes weekly and on 3 occasions 3, 9, & 5 hours respectivly. We have used about 25% of our LP tank. Best decision for comfort & security we have made in a long time.Thanx, Generac April 22, 2014
Rated 5 out of 5 by Very quiet,powerful,relatively economical good investment I live in Louisiana approx 15 air miles from Gulf of Mexico Hurricaine-prone area the QT2524 has reliably run 24-7 when Hurricaine Gustav reared it's ugly head...this generator performed flawlessly and ran our entire house, Central AC and all appliances for 7 1/2 days we stopped it after 4 days to change engine oil & filt (very simple task) and cranked it up again; a very quiet well-made unit that I would recommend to anyone. I noticed the QT25 is no longer offered but the QT27 is avail. whichever QT series you buy, you won't be disappointed with the service! Note: this unit runs on natural gas & was installed in May of 2008 March 29, 2014
Rated 5 out of 5 by Excellent investment Best investment we've made. Unit is well sized and quiet. Does exactly what we need it to do. December 20, 2013
Rated 5 out of 5 by High end After listening to everybody say diesel is better, we installed this unit on a 3200sq beach house in Puerto Rico. Being so close to the sea, the aluminum enclosure is a must. Very quiet, smooth running, powers everything in the house with power to spare and best of all, we do not poison our neighbors with Diesel fumes! Generator is hooked up to a 120gal LP tank, has run 30 hrs already without a single problem. Best warranty, other units offer only one year. October 2, 2012
Rated 5 out of 5 by Peace of mind! This generator just ran for 115 hours following Hurricane Isaac's overstayed welcomed in New Orleans. Best home investment I've made in a long, long time. Unit is powered by natural gas and ran all systems in a 3400 sq.ft. home plus pool. Strongly recommend this product. September 5, 2012

1 Person needs an answerI have this question too


Recommended fuels should have a Btu content of at least 1,000 Btu's per cubic foot for natural gas; or at least 2,520 Btu's per cubic foot for LP gas. Ask the fuel supplier for the Btu content of the fuel.
