It works

After 19 years we replaced our old Generac generator with this slightly larger, newer version. I like that the air conditioner doesn't bog down the generator. It has no problem running our modest home.

Terrible Purchase

Purchased a month ago and it is still not operational. Both installer and generac have no idea why it is not working. I am Currently going through the loan company to see what rights I have

Peace of mind!

I bought this before Hurricane Beryl.It ran flawlessly for 49 hours. It has ran through several other power outages since. Peace of mind is well worth the price

Peace of mind

Haven't lost power since it was installed but the security of knowing I'll have uninterrupted power is immeasurable. In addition the supplier/installer, Gen Ready, is excellent!

One year - no issues

Has been installed one year. No issues. Performs a test every two weeks. Operated properly during two brief outages, less than 15 minutes. App works well. Having a generator provides a peace of mind. Glad we had it installed.

Love owning a Whole House Generac Generator

We have only had the generator now for less than a month. Luckily we have not had any power outages and have not had to use it. I will say, that when I hear a storm is coming our way, I do not panic or worry about having an outage.

Piece of Mind

We love this product....We had a faulty part that was trouble for almost a year but after it was narrowed down and replaced....the 22kw runs like a dream. It's a wonderful item.

Has never worked

Has not worked at all. How Generac can release a product that has software issues. I paid all the installation and equipment money for a product that has never worked.

Great features

We bought our generator a month ago and are very pleased. We had a problem free Generac generator in our previous home that we were very happy with, which lead us to buying another in our new home.

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.
