As it turned out, our Generac generator had a defective control panel. The defect prevented the generator from properly switching the house over from the electric company's power supply to the generator's power supply. So, the first time the power went out in a storm, the generator motor activated, but because of the defective control panel, we remained without power. That caused us some real concerns and worry, a long 3:00 a.m. conversation with our electrical contractor, and two warranty visits to get the new control panel installed. Since then, the generator appears to operate correctly. The power went out one other time, and we had no problems. Just the same, we have a small remaining "trust" issue with the unit. A manufacturer defect can occur in the producing any product; we certainly understand and accept that fact. Yet both the manufacturer and the unit installer would do well to test for control panel defects. On the plus side, Generac fully stood behind its warranties. All in all, we like the generator, and remain optimistic that it will give us many years of reliable service.

Pretty straight forward install. My actual costs were about half what a pro quoted not including chasing parts and my labor. Commissioning was straight forward also. Notable notes: Im not 100% satisfied on the auto start. The engine start takes longer than i like and it stumbles a bit. Plan to recheck gas service. Its also a bit louder than expected. From pre buy conversations with local dealers i dont expect much support either because i didnt give them the total sale. Consider that before you buy from a wholesaler.. I will review again after the first power loss.

That's what I like. The generator is always ready for action. Electricity fails, generator cuts on, never misses a lick. Very happy. I have installed three of these on three different homes and have never regretted it. In fact I have increased the value of each home.

After a hurricane & 4 days with no power, we bought a whole-house generator. Good reviews led us to choose Generac. It has already served it's purpose twice in the 3 months since it's installation. It's quieter than a portable & has kept us up & running with only a few seconds without power. It's no larger than the AC unit & it's case is unobtrusive. We chose propane with a buried tank. We sr. citizens are grateful for the peace of mind.

Adding the Guardian "whole house" system offers great piece of mind that our family and home will be automatically protected during severe weather and any other catastrophe. The generator itself and transfer switch are well made, easy to use and look great too! Hearing the generator start-up every week for it's self-test actually makes me look forward to the next time the power goes out ;)

I am a little uncertain about the product for now. When they came to start it the motor would run fine but it would not generate any electricity. They now have to call the manufacturer and see what the problem is. They have installed a lot of these and say it is the first to do this. I hope it is something small. I believe once the get it working I will be pleased with it.

After building our new home on the South Texas coast and installing our new Generac with automatic start, we moved in in May 2017. Three weeks later, a huge storm hit and our entire town lost power. Needless to say, we were the only house on our street with power and, thank goodness, air conditioning. Our Generac was worth every penny -- we're so glad we installed it from the beginning!

This product is essential to comfortable living in South Louisiana! With many power outages, it would be miserable without it, or even using a manual generator which has to be constantly monitored. I view it as needed as much as having central air condioning. I would definitely recommend it.

In 2006 I bought my first backup generator. It was a 22kW liquid cooled and worked flawlessly. My new one is a 22kW air cooled and is awesome as well. At my old house, I plumbed it to my gas line, this one is on propane which it sips. The notifications to my phone give peace of mind. Great, great product. Beautiful. All other generators are losers.

We have had four power outages since we installed our Generac 22KW generator. It is fueled by our propane system (1000 gal tank) so we never need to worry about refueling it. The automatic test feature provides the confidence that it is ready to step in to provide the power to meet all of our needs when we loose electricity due to grid failure. Peace of mind!
