Dead on arrival

1st unit would not work, and Generac would not stand behind the unit or repair it. The supplier had to replace at cost, and I had to eat the cost or try to repair the 1st one and the installation of the new one.

Don't buy this unreliable generator

I bought this NextGen 28kW to replace a rusty but reliable 20 year old 35 kW Generac. Our NextGen failed immediately at our first power outage 3 weeks after installation and is still nonfunctional after 3 service trips and more than 4 hours labor over the last week.

Peace of Mind

I purchased this one year ago. It is whole-home capable, completely automatic and easy to monitor with the phone app and the Ecobee thermostat. The generator responds to power loss in seconds. It is very reassuring to know that if our home loses grid power while we are away the app will notify us.

Reliable Protection

Purchasing this generator was similar to putting up a magical ward against power failures. Where the original motivation was a frequent number of outages, we've not had any single outage since installation. In it's standby configuration it's met our expectations.

Generator Upgrade

This is our second Generac generator because, after 19 years with our first one, we wanted to upgrade to one with more current features/functions. Our first one was purchased in Sept. 2007. It gave us optimal, quality, and dependable service. It is still working today, in another household, with a family whom we gave it to. We look forward to and are confident that we will have the same level of quality service with our recent new upgraded generator!

Hurricane Prepared

4 years after Hurricane Ian it was time to replace a portable 5kw generator with a whole home generator. We will now be able to have the entire house on standby power should another major outage occur. Being familiar with the Generac company based in Wisconsin, this was the only generator considered.

Insurance policy for the future

I purchased this generator in July and the installation was completed in August. The installation was very professional. I would recommend One Way Electric in Phoenix for the installation.

Fast and efficient.

I finished installing my generator a mouth ago. I have my first outage during a storm. The generator performed perfectly. I am very happy I installed this generator system.

Something is Wrong with it

I bought this a month ago and it’s still not working properly. It runs for 15 seconds and then shuts off. After five cycles of this it stops altogether. They are still trying to figure out the issue. I am happy to review again once it works properly.
