Ratings & Reviews for Generac Next Generation 24000 -Watt Dual Fuel (Liquid Propane/Natural Gas) Home Standby Generator

Junk wish I would’ve went with a different company

L I bought this generator less than a month ago and it broke down within the first month installer keeps canceling my appointments to figure out what’s wrong.

Poor Product

Generator was installed and does not work. Installer is doing their part to troubleshoot. Extremely disappointed with the product, not the installer.

Faulty equipment

Generator has only operated for 107 hours and quit running. Very difficult to get warranty service.

WARNING: Don't buy - too many issues

The Generac NextGen generators are new machines with problems. My generator was installed in April 2026, it ran a few exercise cycles and broke down. Repairs made. Lost power three times in June, broke down each time within 3-7 minutes. Broke down in July for a power outage and exercise cycle. The installer wanted to fix one part at a time, as you can see the uploaded photos the generator had many issues. As of today 8/30/2026, it still sits broken. I wanted a removal and refund; Generac a...

Peace of mind

I bought this last month. Dealer was very fair in pricing. Installed in a timely manner.

whole home generator 26kw

had it for a year. no ;issues whatever. app is relatively easy to use.

Best Buy Ever!

Best buy we have ever made. A month and a half after it was installed, we had a big windstorm in Montana (in December). Power was out for 3 days, but our Generac generator started right up and kept running for 3 days, with NO problems at all. Kept us warm, kept the lights on, kept the hot tub hot. We could cook and go on with our daily lives with no hitch. It's a Godsend!

Fast Power Transfer

I finished installing generator a mouth ago. Pretty straightforward installation. I had my first outage during a storm last week. Generator started and transferred power within seconds. Very happy with quality and performance of my new generator system.

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.

Bought and installed in the last month , gives us piece of mind , as well as the ability to work from home without interruption.

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!

great unit

This is a great unit and we love it. best buy we made

Don’t know enough about the unit

For all the money I spent on this unit I should get a new complete replacement

We had it installed for one simple reason. My wife is on oxygen and we can not have a power failure endanger her life and wellbeing.

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.

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.

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.
