So far, so good!

I have had my generator for about six weeks so far. The installation was quickly and efficiently accomplished. The installation team answered all my questions and explained the operation of the unit. So far, the only experience I have with the unit is when it tests itself every week. I have yet to experience an actual power outage and run on my home on generator power alone.

New and improved version

Just installed and completed and we have no issues. Had to leave our first Generac at the old house and now have the new and improved version. The simplicity of managing is great, have recommended to our neighbors and they are being installed and ordered as I type.

Seamlessly continues power supply.

I bought this unit for a rental tiny home on my property. I had already installed a 17kv Generac which services the main house. We have electrical outages several times per year in our rural location and our Generacs work flawlessly to seamlessly continue to provide power when this occurs.

Not the first, wont be the last!

Our most recent purchase was a replacement unit for fhe original used unit we had for 10 years. We did not even hesitate when it came for the replacement. Our first unit was about 5 years old when we got it and it lasted another 10 years and was an absolute blessing when we needed it. So happy we installed a whole home generator shortly after we moved in!

Does the job well!

I have had it for a year now, and of course there has not been a power outage since the installation. However I did decide to run a simulation of an outage and was very happy with the results. My only issue is the description provided on Generac's website, makes it sound like the noise level is just above the level of an air conditioner. If I had an air conditioner that loud, I would be worried!!

New generac blew oil and then just quit

We paid over 10 grand just a year ago for brand new generac. It's only ran for 5 minutes at a time for its weekly test. We lost power 4 days a go. The generac kicked on and has ran solid. We haven't used much power. Mostly lights and fridge. This morning, the generac just quit. Went to check it out and it has blown oil out the side. They say our power is still a day, possibly from returning. Called generac and they can't get anyone here for at least 3 days. I'm very disappointed and sickened that we spent well over 10 grand on this product. I don't feel at all comforted ,now, for having it for emergency.

Love our Generac❤️

We have been thinking about buying a Generac for years. So glad we finally did! Our neighbors had their installation done in 2018. Every time a storm caused an outage, they were completely comfortable, up and running! It has made us feel much more secure with the hurricane season coming.

50/50 feelings

I wish I had better things to say but I feel the company that installed the unit did a poor job the unit leaks oil and when I told them about it on the 1st maintenance visit, they wanted charge me extra this was part of the installation and has been leaking ever since . Other folks may have a better experience with this brand I think it was just the company that has installed mine .

Not working to specification.

Been over a month and I have no resolution to an Engine Speed Alarm/Fault that renders the system to not initiate automatically as designed when my power goes out. Without this key feature operating correctly I feel dissatisfied. No eta has been provided for a fix which adds to my frustration.
