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

Missing parts
Would Not RecommendI purchased this generator on July 12, 2026. It was delivered Aug 26, 2026. When the electrician went to install it, the key was not included in the box nor were there any instructions. I have been trying to get a key and instructions since August 28. I have been given the run around. I was instructed to contact the dealer and a local dealer/contractor in my area to get a key. Today, I asked to return it since I can't open it to have it installed. They said they would call me tomorrow with a pic...

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.

You won't be disappointed!
Would RecommendI 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
From generac.com
The app is very good and verifies its working
Would RecommendHad this 6 weeks now, just before storm season. Good quality product but difference is the installation by a company that only does generators, not some diversified franchise or one-at-at-a-time electrician. Family run business that concentrates on Generac and installs 5- 7 per week. The price was $2800 less than other vendors and they gave me the confidence of a quality installation and maintenance program.

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.
