Rated 4.9 out of 5 by 17 reviewers.
Rated 5.0 out of 5.0 by New install We just got this generator installed about a month ago and couldn't be happier with it. It doesn't look bad, and is very quiet. It sits outside next to our master bedroom. March 23, 2015
Rated 5.0 out of 5.0 by Product works perfectly in maintaining power during frequent power failures We now have peace of mind knowing we have continuous reliable power for our home.We have frequent extended power failures where we live which gave us constant stress due to possible damage to frozen and refrigerated foods.Since the installation of the 22K generator we have no worries.The generator works perfectly all the time with excellent fuel economy. A highly recommended product. March 11, 2015
Rated 5.0 out of 5.0 by Excellent Choice While we bought a unit that is a bit larger than was needed we have had the occasion to use it 3 times this winter and it worked fantastic - very seamless operation. Couldn't be more pleased. Just what a senior citizen needs for peace of mind! March 11, 2015
Rated 5.0 out of 5.0 by This product has worked well in a power outage. For 2 1/2 hours this past month when we had a power outage it did an excellent job of running smoothly. We are pleased so far with its performance. March 12, 2015
Rated 5.0 out of 5.0 by Excellent product Carefully researched products using unbiased information from reliable testing sources and found that this product not only met our needs but was excellent quality and great value. It is quiet, unobtrusive in appearance, and valuable mobile link. Service excellence by the dealer as well. March 6, 2015
Rated 5.0 out of 5.0 by convienence and satisfaction we purchased our generator late last year and really got to experience the convience of one on febuary 2,ground hogs day,our power went off around 3 in the morning while our furnace was running which is what woke me up,the furnace had shut off and started about three times all of a sudden and I thought it had blown up, but then iy went clear off and within a short amount of time the generator kicked on and the furnace came back on with no problems,this is really nice to know that when your power goes off you don't have to worry about anything,the generator will come on and run anything in your house without having to go outside and drag out a portable generator fill it with gas if you have any at the needed time and plug in your extension cords,which does not run everything in the house.the convience of be able to get up in a power outage and flip on a light switch and have light really is great,which is a small thing in comparison to having heat and hot water but it's nice to be able to do.

Rated 4.0 out of 5.0 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 5.0 out of 5.0 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
