Verified Purchase

Outstanding!

My unit was provided at best price. Delivery timely and professional. Installation superb and was coordinated with my LP provider without my intervention. The unit is extremely impressive, technologically advanced and provides security for me and my family. If and when it is needed I am confident my home will be secure. Thanks Generac!!

Works Great!

We purchased the Generac 22 kw Guardian system in October of 2015. I installed it over the next several months as I had the time. A few months later we had a power outage for about 5 hours. When the power went off the Generac powered up in about 15 seconds. Wonderful! I am writing this review 2 hours after our power has been restored this morning January 25, 2017 at 8:45 am. We had a very bad ice storm on January 14, 2017 and thousands of people have been without power. Many still have no electricity as I write this. We gave this generator a very good 10 days and 9 hour workout. My wife and I highly recommend this generator.

Not working to specification.

Been over a month and I have no resolution to an Engine Speed Alarm/Fault that renders the system to not initiate automatically as designed when my power goes out. Without this key feature operating correctly I feel dissatisfied. No eta has been provided for a fix which adds to my frustration.

Runs quieter and has great App features.

We bought this 24KW four months ago and was only able to get it installed a month ago. So far we're very pleased with it. We bought a 22KW Generac 20 years ago and got a lot of usage out of it in south Louisiana. Back then it was referred to as a "whole house generator" but we soon learned that didn't mean you could run "everything" in the house on it. It running under a load because of a power outage and my wife was running the clothes washer, dryer, microwave, the electric oven and all the lights at the same time and it handling the load just fine until our 3.5 ton AC kicked on and it started to bog down badly. Lesson learned!! We have only used this one in the exercise schedule and not under a load yet. It is quieter than our old one though. Be sure to get the App for it if you want a more detailed status of it and setup an exercise schedule.

If you have the extra money, put it to GOOD use!

We have had the unit for about 10 months. It now tests twice a month for 10 minutes self checking and keeping the oil moving around. We had an outage the week after it was installed while we were away. I received a notice of it working, via the app, as it was supposed to do. We have had two other outages last year. The unit performed perfectly. So far so good! I had a year of complimentary wireless coverage. I just signed up for the next year. While not really a cheap benefit, it is nice to have. I may change to testing once a month later. We used to have outages every other month around my neighborhood due to weather, trees and old lines. Consumers has done a good job of cleaning up the lines and overhanging trees. The outages are fewer now, but as an older person, I now join the group of people that are more susceptible to cold, heat and less flexibility in dealing with the inconveniences of power outages. Our Generac should make things easier!

Ease of mind.

When installed we were very pleased. In the past year it was only needed for a few hours but the ease of mind is well worth it. Sound is a bit loud and weekly testing is very reliable, The wifi needs improvement when the signal is lost. It is a bit difficult to reconnect. Our installer was excellent.

2026 Generator SUCKS!!!!

We purchased a brand new 2026 Generator. It is now April and the thing still does not work. Every time the power goes out ... the generator runs for 5 seconds and then shuts down and we get a "failed" message. Our installers (Blue Sky Plumbing) has said they have installed 23 of the these same generators and ALL OF THEM are having the same issue. I would not purchase a new generator again from these people and if we don't get our money back ($50K), we will be suing Generac.

Just do it

I was hesitant to purchase this at first. My wife insisted that we do. Since purchase we have had 2 major storms and the Generac has performed flawlessly. The whole valley was without power for 2 days and we were eating popcorn and watching Netflix. I will say that we can hear it running when it comes on, but it's a small price to pay for comfort.

Power in mind

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.

Excellent Great installation, look great Very impressed with the Installers effort to evaluate our power requirements He contacted the local utility company and found out our average and peak power utilization from the past two years and installed a system that will totally support the whole house
