Customer review summary generated by AI, including incentivized reviews.Excellent from installation to education
This is our second Generac as we recently moved to Florida and had to leave our other Generac behind. The feeling of security it provides, and the almost instant continuation of electric service to our home, is worth every penny of its price. Our Generac dealer made the entire process simple for us, taking care of each detail involved with the installation. The instructions provided were simple and clear, and they made sure we knew how to reach them with any questions or concerns we might have. ...

Air filter issue on brand new 22KW generator

Great machine and Great Peace of Mind!
I purchased this unit in August of 2024 and to date, it has performed flawlessly. We've only had one brief outage but it ran then and runs every week for 10 minutes to exercise. The Mobile app gives me all the information I need at my fingertips and is easy to navigate, even for a 68 year old!

Honest opinion
Generac has reputation of general quality at reasonable price. I do not like the mobil app being only control you have of generator. Much more prefer the on unit control screen. Design and appearance is good, but wiring entry should have more options than the one entry point. One eyesore is the gas regulator having to be 5' from generator. This is requested by Generac not local jurisdiction inspection. This also adds to possibilities of damage to gas line which outweigh the gain of safety by pla...
