Solid Generator
My generator has worked flawlessly since I purchased it. Unfortunately I have been unable to get it to work as I had intended, which is to run my pool circulation pump during winter power outages. I have verified through multiple electrical experts that my connection from the generator to the pool equipment is correct. My next step is to adjust the Hertz output down to ...

Didn't even get a chance to use it/ it failed.
I bought this new generator new in the box for our deer camp. We unboxed it and added the oil and clean gasoline and started it. It was gushing gas out of the carb so we had to shut it down. When we called Menards to bring it back for an exchange they said that they don't take them back and we had to bring it to a certified repair shop that was 75 miles away from our ca...

Response from Staples :
Thank you for sharing your experience with us. We’re very sorry to hear that your generator arrived in that condition and that it disrupted your deer camp plans. Opening a brand‑new unit only to have fuel pouring from the carburetor is absolutely not the experience we want for any customer. While retailers set their own return policies, it’s unfortunate that you were sent straight to a repair shop—especially one so far away—and then couldn’t use your generator when you needed it most. We also recognize how confusing it must have been to hear that the carburetor was full of “gunk” on a machine fresh out of the box, and that the repair shop wasn’t compensated. That would raise questions for anyone. We want to look into this further for you. If you’re willing, please reach out to our Customer Support team at 1‑888‑GENERAC with your generator's serial number and any repair documentation you received. With that information, we can review what happened, work with the servicing dealer, and ensure you’re supported going forward. You invested in a generator for reliability and peace of mind—please know we’re here to help restore both.

Overall, very good quality and features.
Just bought this a month ago and haven't had the need to use it yet. But I did have to assemble the handle, wheels, add oil and gas and start it. My review is solely based on that.
The wheels were relatively easy to assemble, keeping in mind that the machine is heavy and you will need to lift it on blocks, or use a helper. They give you a perfectly shaped funnel to ...

Thank you for taking the time to share this. We’re sorry to hear that you’re still waiting on your replacement since purchasing your generator on December 1. That’s far longer than the experience we want for our customers, and we understand how frustrating this delay must feel. We’d appreciate the opportunity to look into what’s causing the holdup and help move things forward. Please reach out to our Customer Support team at 1‑888‑GENERAC with your order details and generator serial number. We’ll work with you to get this straightened out as quickly as possible.

Will run the whole house.
Bought generator on Amazon black Tuesday. Still breaking it in. Electrician said it was a good product. Starts easy with on or two pulls . Hope I never have to use it to run the house but if bad weather sets in I will be ok.

Nice generator
This geneator will be great when we are boondocking with our RV! It requires gasoline which is a minus for me because of the smell but at the same time, it is easy to find and purchase. This is a very heavy item, and you will need a friend to move it around!

Quality Generator
The Generac 5500 generator was very simple and easy to put together. Adding oil and fuel easy as well. Start-up with manual startup was fairly easy. This unit also comes with a battery for an electric start which is pretty cool. The load can handle several small appliances such as a refrigerator, freezer and a TV or you can use it to run a single 220 volt HVAC system by...

Solid, well-made unit.
This generator is everything it claims to be. Easy to set-up, use and is reliable. I hooked it up to my home for a test-run the day after I received it. It started up instantly and powered the entire "critical function" sub-panel in my home (HVAC, water/well, freezers/refrigerators, water heater (gas), water softener, garage door, washer/dryer (gas), WIFI/network and ...
