Peace of mind

We bought it last month and hope we never have to use it for emergencies. My wife is on oxygen and needs it almost 100% of the time. We bought it so her oxygen machine would still work if we had a power outage.

24KW in Ohio

Everything works as planned. My install was April 2025 and I just had an event in March 2026 where the unit ran for 24 hours consecutively. No issues. And very little oil usage. My recommended installer is 5*.

Glad we did it!!

We bought this a month ago. No power loss, so I not sure. I do feel good about the unit covering any power loss. It the next generation. So the phone application could use some improvements. Im sure they will improve over time.

I had the generator installed in 2024 and we had a hurricane in September of 2024, and was without electricity for over a week. My genetic worked beautifully. I just love it.

Peace of mind

The unit works very well, and it has provided service several times when the electric grid failed. It provides us with a great feeling of safety and peace of mind.

Generator Experience

The experience of getting the generator and getting it installed was a big pain. It works as expected and will see how it does when the electricity actually goes out. Time will tell.

Peace of mind

Bought my Generac after an ice storm and a tornado. We have only had to use it once since it was installed. Knowing I can heat and cool my home as well as protect my pool pumps and hot tub equipment from freezing is well worth the investment!

No more worries

Within 6 months of installation we had a 2 day power out event, so the peace of mind was worth it, since it was at our 2nd home and we were not there.

Right on time!

My 18KW Generac standby generator is one of the best investments that I have ever made for my home. The unit supplies all of the emergency power needs to my home during a power outage, which occurs frequently in my neighborhood.

Runs when needed

I purchased 1 year ago. So far it has run on call as expected. The installer contractor is very expensive and annual maintenance is ridiculous. 600.00.per year
