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.

The generator performed great during Hurricane Sandy

I purchased this generator after the issues with Hurricane Irene. When this storm hit and we lost power, I simply brought out the generator, hit the switch and forgot about it. It performed great. I ran my boiler, refrigerator and a TV. I have and will continue to highly recommend this product.

This Generator is a Life Saver

I live in Louisiana I’m 38 year old dad of three kids that just lost my wife to cancer she was my "high school sweetheart”and loving mother of our kids and our area just recently got hit by Hurricane Laura. The storm took out a 100% of the towns power and knew it would take a long time to restore all the power and we all know how it is with no power so I drove to another town not hit by the hurricane and purchased what I would call a life saver and the best purchase Iv ever made the Generac RS5500 Iv heard nothing but good about this brand so I had to see if it held up to its reputation I got it home it was easy to put together very detailed instructions and steps for operating and maintenance it also came with a heavy duty 220v to 120v extension cord with a 4 way plug in to run your regular extension cords off of and I love they included that with the generator because that cord alone is very expensive to buy and very useful it also came with break in oil to get you started so straight out the box I was impressed but could it run and operate as good as it’s reputation was and I’m here to tell you it 100% did run and operate as good as it’s reputation. The first pull and it cranked right up I plugged in everything we needed and still had more power I could have used off of it. I ran this generator only stopping it for its break in oil change and oil changes and Maintence checks after that. This generator ran like this for two weeks until power was restored and I’m here to tell you as a dad with kids needing to keep them cool and have almost all the functions we would with power this generator did it all even my kids were impressed on how it could run that long and that good and they were happy to see there dad not having to struggle fixing something or seeing the frustration in me of something going wrong or breaking down so that In itself should show any future people looking for a reliable generator easy to operate worry free generator that this is the brand to buy don’t even hesitate on which brand to purchase I’m telling you Generac Generators is the only brand you need to buy unless you want to purchase another brand and have the thought of worrying if it will crank or break down so if you want a worry free piece of equipment that helps your family not only survive but survive comfortably and a brand you can count on then do what this dad did Buy a Generac Generator and your love ones will thank you because it’s not only a Generac it’s a Life Saver!!!!!!!!!!!!!!!

Great unit

I live in an area that is rural and the power goes out a few times a year. A month ago we had a storm and lost power for about 24 hours. I had a little generator but it was only good for a couple lights and t.v.. Problem is I have a refrigerator, a freezer, and a well pump I need power to as well. Next week I went looking for a bigger more reliable generator and found it with my generac 6500. After I got it home I was actually hoping to have another storm knock the power out so I could see how it would do. Wasnt long and it happened! It was only about a week later another storm came through and knocked the power out for about 7 hours. Long enough to try out the new generac. Rolled it out easy enough even though it's pretty heavy, pulled once and it was running like a champ. Plugged in the necessities and it handled everything. It was so nice to have in that situation. This winter I plan on having a transfer switch so I can run everything from lights to heat. I'd recommend this generator if your looking for one.

Needed for immediate concerns that we may need it

Having no backup plan for heat and concerns we may lose electricity with forecasted temperatures at -33°. I wanted piece of mind knowing it would sufficiently power our furnace and any other things we need. Started right up on first pull, battery wasn't charged straight out of box when I did initial start, but works now that it has been charged. Great product.

[This review was collected as part of a promotion.] My review for the GP8000E COS W/Cord 49 St. One day after receiving this my town flooded. We were without electric for 2 days. We ran our refrigerator, tv and window ac off this. Very nice!!! Not to loud. Easy to turn on.

Excellent quality and features for the price

I bought this generator on the recommendation of a friend who has this same one and from all of the positive reviews that I have seen online.Upon receiving the generator,the only thing that I had to do was (easily) install the wheels and handle,connect the battery and fill the oil(included) and gas.It started right up.I really like the electric start feature,my wife will be able to start it if I'm not home.I haven't had to use it yet in a power outage but now I'm ready.

Cost effective and easy to setup

After close to a week with no power I decided it was a good time to look for a generator powerful enough to get everything we absolutely need. The 7500E only took about 10 minutes to setup but keep in mind you should have 2 people to easily unpack and setup otherwise it will be a little more difficult but not impossible. Parts seem strong enough and the unit started right up and runs pretty smooth. Can't say I wouldn't like to see a more quiet units but it's not terribly loud either. Overall, very happy.

wasn't allowed natural gas or propane

I needed to run my entire home inn case of a Hurricane. This was the only generator gas powered to accommodate our needs. 50 amp service was more than enough, ran my entire home for almost 3 days till power was restored. I was extremely happy. I referred this model GP17500E to a friend he bought one and like me very happy thank god we didn't need it so far in 2018.

The Little Generator that Could

During Hurricane Sandy we were without Power for 13 days. My friend got power back in five days so he lent me his Generac GP 6500 and it powered my four bedroom house for 8 days without a problem running about 20 hours a day. So I went out and bought one for myself. My neighbors with bigger generators were very impressed with my little generator that could.
