CUSTOMER REVIEWS

Rated 4.8 out of 5 by 249 reviewers.
Rated 5.0 out of 5.0 by Great product. Highly recommend This product is great. We've had numerous power outages over the last year and the generator has never failed. August 7, 2015
Rated 5.0 out of 5.0 by Extremely satisfying! We got a 20 kW Generac installed the summer of 2014 when we moved into a new home. The previous owners had one already but decided to take it. So we just replaced it with a brand new one. So far we have had only two power outages. One in January of 2015 and one about a week ago. We were so happy to have it when we lost power during the ice storm because the whole house could be heated! Also when we lost it a week ago our neighbors were without power for 3 days from just a pop up summer storm, but we weren't because we had a Generac. All of our neighbors had to leave their home to go to a hotel because there was 100+ degree temperatures during the day. We were so relieved that it our generator could run 2/3 AC units and everything else in our 5,000+ sq. ft. home! This was our first backup generator and have been very satisfied since we have moved. So far it's been great and hope it will last a long time. I just wish Generac made an air cooled generator bigger than 22 kW because they are so much more affordable then a liquid cooled and some people don't want to spend $15,000+ dollars for a liquid cooled model that will run 3 AC units at once!

Rated 5.0 out of 5.0 by Great product Installed 20 kW unit with the smart transfer switch in November of 2014. Simple enough to install. Not for a do it your self project without a huge understanding of multiple trades. Started by picking a 17kw unit. Bought it, waited and waited for it. 2 months later, I finally walked into my supplier and asked in person what is going on. After the run around, they informed me that the 17kw was not available anymore. So I changed suppliers and went to a 20 kW. Had my unit delivered on the next day. I poured the pad one night after work, landed the unit a couple of days later, took a full day on a Saturday with 2 guys to complete the install. Overall, I am happy with the unit that I have.

Rated 4.0 out of 5.0 by Only had it for 2 days too early to tell Looks good starts good just waiting an outage! It looks like my text is to short so xxxxxxxxxxxx oooooooooo xxxxxxxxx ooooooooo try this July 3, 2015
Rated 5.0 out of 5.0 by model 6729 20/18 kw Generac Generators are extremely dependable in 15 years of owning one and having numerous power outages our generacs have never failed us July 3, 2015
Rated 5.0 out of 5.0 by Worry Free Area has been hit with power outages of over 22 days in last 2 years. Newly renovated house has sump and sludge pumps and if the power goes out . . . . Whole home generator comes on, we have well water and no worries. Transfer system awesome, techs were professional and very well organized. Even in the -20 degree day of installation were great to work with. 4 thumbs up (wife and I). June 12, 2015
Rated 5.0 out of 5.0 by Has shown it is commercial grade We installed the system 3 years ago. There has only been one issue with it when one winter cold snap brought up the need for a cold weather kit. This kit should have been recommended by the installer. No issues since then. In one outage it has ran continuously for almost 5 days without a problem. The one feature item that is needed is to have the system charge the battery while online. Running without a charge for extended periods risks a failed restart if, for example, you stop for a short period to check the oil level. May 26, 2015
Rated 5.0 out of 5.0 by worry free connectivity I've had my generator now for over a year and am very satisfied. Although we have not had any significant power losses, the power has gone out several times for a few hours at a time and the generator has performed well. I work shift work and the power losses were at night, so my wife was very happy that she didn't have to lift a finger to get the power back on; the generator auto started and auto transferred to power the whole house. Very satisfied. May 22, 2015
