Good machine. CO sensor and GFCI to sensitive

GFCI trips when I plug in my refrigerator. CO sensor keeps shutting down my unit that is placed outside not even close to my home. I had to put a box fan under the handle to blow air across the unit to keep it running. I dont need the CO shutdown. Other than those 2 items I am impressed.

Finally was able to use my GP17500e

I purchased this generator new approximately 5 years ago. I left an initial impression review at that time. Other than monthly test runs, I have not had to use it. Last night it was finally used to provide power for the entire house. It worked flawlessly. It was 28 degF. When I started the generator and it ran continuously for 16 hours with no shutdown. Temps got to a low of 6 degF. It’s one thing to lose power in the summer. Losing power when it is in the single digits is an altogether different scenario. Our house has baseboard electric heat that had to work in some rooms not heated by the woodstove. In conclusion, and as a follow up,after five years it did exactly what is what purchased for.

Good but pricey

[This review was collected as part of a promotion.] I was sent this generac generator to try and review. It cake just in time because 2 days later the oowpo went out due to a storm. This ran quietly, compared to other brands, and efficiently. I would recommend it if you can afford one!

Terrible warranty/parts service

I have had this machine for about two years. I am giving Generac one star because their customer service and warranty repair is very poor. I was not able to acquire a warranty part from the factory. My dealer was not able to acquire the warranty part from the factory. I could only find one repair shop that was willing to do warranty work for portable Generac, generators, and they took six months to repair my machine because Generac did not quickly supply them with the warranty part that they needed to repair my machine.

You absolutely need this!

[This review was collected as part of a promotion.] Y'all!! This generator is huge! Built to last and so quiet to use! Being able to use 3 fuels makes it accessible! Was so easy to assemble and easy to maneuver with its handles and wheels! It powers our big farm house with ease! Definitely going to be a big help during power outages or whenever we need added/extra power!

Great product

Had to replace the generator I left behind in my previous home after 14 years of use. It was a Generac. I looked at several other brands, but settled on the Generac because of the reliability, wattage and value. Received it yesterday, assembled the wheels, feet and battery, and it started on the first try. Thanks.Tim31

Changing of the guard

We have been running our old 15KW Generac Guardian Ultra-source gasoline generator for the past decade to power our home during after hurricane power outages. The Generac has always been dependable. ( Be on notice however, if there are huge amounts of ethanol in gasoline, the unit WILL NOT RUN. A thing that may or may not be an issue after a hurricane ). We only run non-ethanol as a standard with fuel treatment, bolster your reserves. With standard maintenance (oil, plugs, filters,battery,,,) and running for 30 minutes+ every month, it has aways been “at the ready”. After 10 years, we are pulling the 15KW from service to rebuild the unit and it will be a backup. The 15KW would run 1 of 2 Central Vac systems, the heavy amp draw well pump, kitchen, home theater, lights, water heater, etc,,. Naturally we can shut subsystems off to conserve fuel. We do have our property in the swamps of Florida, 2 miles from the main road, so we are the last place where propane will be delivered after an event of a hurricane or other crazy events, that is why we chose gasoline. We purchased the new Generac 17500 and was delivered yesterday. At unboxing, we realized that the wheel axle was missing. Fortunately we had our existing 15KW and we had a working axel to maneuver the new 17.5 Generac through the landscaping into position. I thought, “here we go!”. I called Generac Support the next morning and “Bam”! The support rep was an English Speaking American in the States (Chris) and the part is on its way,,, UPS! 15 minutes of may time, done! Wow! It’s a bummer that my new purchase was missing a part, but I am surprised at the quick phone pickup with a fix! We will see how the new Generac performs, as it is expected to a active hurricane summer in Florida, The El’Nino weather effect is drifting away again.

Cranks easy

I bought the 6500e to run my heat pump, I have a generac 17kw standby unit but the guy that hooked up find the wire the heat pump in and was less trouble to wire it outside for a portable unit. This unit fires up in a half a turn with the electric start and pulls the heat pump with ease!

Nice generator

I purchased this generator after purchasing and returning 3 Westinghouse generators. 2 generator was defective and the other 1 would not power what I needed. Purchased the generac and am very satisfied with its performance. No issues with this generator. Provides all the power I need for my camping needs.

this product has great features

i highly recommend everybody having a generac generator as an emergency backup after going through hurricane irma and having no power for 8 days and we lost all of our perishable food in deep freeze and refrigerator because we did not get generator until after the storm but so glad i ordered it because of the unbearable heat in florida and we were able to run window ac's and well to take showers very satisfied.
