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.

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.

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.

Good generator for the entire house.

Have had this generator for a year. Had to have a faulty emergency switch replaced (under warranty). I've put about 11 hours on it. It's able to power everything in my 2500 sq/ft house (A/C, Heat, oven, dryer) all appliances with no issues.

Reliable Power

Just completed year two annual maintenance. Generator has activated reliably 5 times over the past two years and powered my home without any issues. Propane usage seems very efficient.

Great Whole Home Generator for my house.

I purchased this one month ago and could not be happier. The installation went great. Generator runs like a clock every week for it’s week test.

Doesn't run! Doesn't work

15 plus thousand dollars waste of money. Our contractor called the generac service tech at our home 04/17. Unable to reach the generac service tech after the contractor spent most of the day at our home trying to get the generac generator to run.
