No news is good news. In the almost 1 year since we purchased it, no power failures, thanks. It faithfully runs 5 minutes every week to let me know its ready and willing when the time comes. Hope it continues on that cycle, best investment I ever made.

Got the unit about 11 months ago. Haven't had any power outage yet. It runs once weekly as it's supposed to. I did turn off commercial power a few weeks ago to test. Couldn't do it long enough to test the power shedding to the furnaces. But no issues yet.

This is my fourth whole house Generac generator that I have purchased in the past 10 years (one each time I moved to another home). They have all been outstanding and very reliable - I could always count on them when I needed emergency power. Living on the Gulf Coast, a reliable generator is a must. I will never buy any other brand.

I upgraded my Generac Guardian generator from 15KW version to a 22KW version (due to load increases). I have to say I am pleasantly surprised on the quality of power being delivered. The old generator fluctuated several hz (+-2 Hz) and had a hard time holding a steady voltage. We are using this generator to power a small data center, power quality is important as UPS don't like dirty power. This new generator holds voltage steady, the frequency is within +-0.1 Hz. Even when the large roof top air conditioning unit kicked in, the generator powered up and recovered the correct voltage and frequency within a second. The power monitoring is also a nice touch. Now I know when we loose power and if the generator kicked in or not. Although the old unit mechanically was working fine, visually the case was metal and rusted heavily. This new case is aluminum so we are expecting no rust.

The auto switch generator we had installed has already paid for itself with the amount of times my family and I lose power in the woods of Maine. It takes a meme moment to kick on, but runs better than my electricity from the electric company. Super grateful and happy to have it

The standby generator from Generac is a great buy! Only days after installation it was called upon to power my whole house during a Hurricane. As my wife is handicapped, it was imperative to keep our power on. I would have no other product but the Generac generator.

I love this new 22KW generator. The dealership and installation folks were just fantastic. They set up a time with my propane provider so that they could all be there during the installation. The install of the generator, wiring and propane lines were all done in one mornings time. We decided on a whole home unit that would run the power in our whole house if the electric service went out and we are very very happy with it. The generator is set to come on weekly and will run for about five minutes or so and does a complete check of the system before it turns off. We also decided to go with the Com-Link option which was around $200.00 and it will send you texts or emails with a report of the weekly tests along with each time the generator is on or the power goes out, a great option for our peace of mind while away from home. There is also an app that you can refer to that tells you the condition of the battery, times the test runs occurred along with Minutes/hours of run times and when the next maintenance is due. Your Generac dealer can also pull up all this information and line out a time with you for upcoming maintenance. As I've said before, I LOVE THIS NEW ADDITION to our family :)

Living where power goes out often, it is much easier going to sleep or leaving home knowing this machine has my back. It does it's routine check once a week letting you know it's fine and has a green light that lets off a soft glow I check for out my window before turning in. A great investment.

My new Generac whole-house generator eliminates the need to refrain from using heat/air during a power outage. Much more convenient. Also, the new plastic housing eliminates the serious rust problem we experienced with the prior metal encased unit. And finally, no more replacing the battery every year. The new charging system has come into the modern ages and does not charge all the time until the battery explodes. Like an iPhone or other device, it only charges when needed and stops at full charge. Overall, I am well-pleases with the new, larger unit and find greater peace of mind in ownership.

We are very pleased with our Generac generator. It was installed in April 2017 and by the end of May we had already seen the benefits of our Generac 3 times! It is quiet, and the switch over from normal to generator is seamless. Great product - so glad we purchased!
