Poor installation

I bought the unit a month ago and I had to contact the salesman about the poor installation. The generator was bouncing across the pad when it came on. The crew came back the next day with Billy to add more dirt underneath the pad and added anchor screws to hold the unit on the pad. Billy promised he would come back to landscape the dirt to prevent erosion. But nobody has returned and recent rains are washing the dirt away!

Great product

Bought this generator about 6 weeks ago. The install was completed without any issues or concerns. Final connection was completed after gas company upgraded the meter. We had a power outage about 2 weeks after the install and never noticed the power going out. The generator started so fast there was never a flicker of the lights.

Generac Won't Replace This Lemon Unit!

I had this unit installed in 2024 & have had nothing but problems with it. Finally after I complained enough Generac sent out another company to ‘fix' the unit during the summer. It ran kind of ok, then today 9/11/26 it stopped & another over speed error showed on the app. This has been a long standing problem with this piece of junk & Generac apparently will not replace this lemon unit! Maybe they'll do something when I get an attorney involved! I know some love their Generac & it appears I have the LEMON. SO GENERAC HOW ABOUT REPLACING THIS PIECE OF JUNK!

Looks and works great!

Very happy with our Generac generator. Provides peace of mind and for those days where the public utility leaves us short. Looks good and easy to use the app for status and system updates. I would highly recommend using a Generac authorized location for you generator

Seamlessly powered our home during utility outage

We bought the generator 2 years ago. About a year ago our utility company had a 5 hour scheduled outage. The generator kicked on within seconds and powered everything in our 3500 sq ft home. We live in a hurricane and tropical weather prone area and so we feel it will be important going forward

reduced stress level

I bought this because of frequent power outage in our area. At my advanced age I was very concerned about loosing power during inclement weather condition. since the unit was installed it has come through for me a few times without any problems. I am very happy and with the results. My stress level during bad weather is greatly reduced.

Wonderful Service

I live in an area that has frequent power outages because of high winds and fire dangers. Having a Generac for backup power is a comfort. It was installed quickly and professionally. I am sleeping better knowing it's ready to spring into action if necessary.

Generac Generator is a Great Product

I bought my generator when I bought my new home. I owned a Generac generator at my prior home and I loved it, so there was no question about buying one for my new home. It has already paid for itself in usage for power outages. I work at home, so this is an invaluable tool to help keep my business running.

Peace of mind

We purchased the generator because we do a lot of traveling and it is a piece of mind to have this generator ready to kick on if the electricity goes out. We have sump pumps in the basement that are almost constantly running, and if that were to stop our basement would be flooded within an hour or so additionally, we have a deep freeze with a lot of meat in it and if we had a power outages for several days and we're out of town. All of that meat would spoil.

Piece of Junk

We purchased this generator in June and, despite repeated efforts, it remains unusable at the end of August. The contractor has ordered replacement parts on two separate occasions for a brand-new unit that has never been operational. The entire experience has been plagued by delays, confusion, and quality issues. Frankly, this has been one of the worst purchasing experiences we've had in years, and we are extremely disappointed that the equipment still does not work.
