DIY'rs?...skip the inconvenience, don't wait!

Replaced name-brand, ng, 15kw mobile (shed/outside/stationary) machine w 26kw Generac. Unit was fine; not enough juice to carry both ac units @ same time. Generac resolved all issues: no going outside to start, easily carries full house load, can be run during storm, no periodic inspections during extended run times. Should've done this in the first place! Great machine w perfect financing (18 mo/no interest)!

You won't be disappointed!

I have been wanting to purchase a whole home generator for some time. Finally bit the bullet an got a 26KW with transfer switch about a month ago. 2 days ago, 08/13/26, the power died for about 4hours. Unit kicked in flawlessly and handled central AC, stove and package AC unit with ease. I like the fact that natural gas is always ready to go when problems arise. Install was truly professional and exactly as promised. I'm a satisfied customer!

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.

Piece of mind

Purchased the generator two years ago and have no issues. Haven't had to use it often but it is a great comfort knowing that we are protected considering the storms that pop up increasingly

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.

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.

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.
