Nice to have.

[This review was collected as part of a promotion.] I was so excited to finally have a generator. Where we live the power constantly goes out even if it’s a small storm. It stays out for hours and hours and we have three children and most of the time we weren’t prepared and had no batteries ready so we sat in the dark. No fun at all. Now I feel so much better because when it goes out we will still be able to have a couple lights on and a space heater. It gives me so much peace of mind. My husband had to take it to work yesterday and he said it worked great! Started up on the first pull. I definitely recommend this generator.

Excellent generator

I use this generator five days a week, all day long. It is a work horse. My only complaint is that the electric start is not dependable. Since the generator starts so well with the pull starter this is not a deal breaker. It is of interest that I've had a few Generac 8,000 watt electric start generators and they all have electric starters that are flaky. Since they pull start so well I live with it.

This product has a remarkable starting ability never had one problem

I live in a single home with oil heat and during the winter I need something to run all of the major things in the house if my power is lost this generator for the price is the best purchase that I've ever made it starts every time on the first or second pull I never had a problem with the needing more power than it supplies and if I do overload the circuit The Breakers work and help me to be confident so that my family is not left in the dark

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.

Great Product

[This review was collected as part of a promotion.] Love the Generac 3600 Portable Generator. Easy to start, very good product, very easy to move. Runs quietly compared to other generators. Like the feature that lets you know when its time to change oil and air filter.

Excellent so far

The generator was ready to gas up and start up when I picked it up at the dealer. It started immediately on the very first try and ran like a top. We installed the transfer switch and tested the generator with the same load I would expect during a power outage. It performed flawlessly! I have a good comfort feeling knowing we will be comfortable during our next outage.

Good bang for your Buck

Just recently purchased a home in Florida, our first hurricane season and Irma made us realize that a generator is a life saver in Florida. We have only owned it for 2 months and it was a big purchase but well worth it. We only used it for 2 days it is on the loud side but it does the job we expected it to. Overall a good purchase so far... time will tell.

This product was well worth the money.

I bought this generator after Hurricane Irene and I had to put it in service during the freak October snowstorm that hit the East Coast. It performed as well as expected. I used it for 36 hours without a hitch. My wife was happy to have hot water to take a shower and also she enjoyed being able to use the microwave. I argued with her for 14 years as to the pros of having a generator. She always said it would be a waste of money, guess what ? Her tune changed during the snowstorm. She was happy to have the generator.

This product is just what I needed.

Having used generators with pull start, I was not able to pull with my bad arm. So I looked for one with electric start and chose the Generac GP 8000. Glad I did. Easy to hook to my house, and it powers my house, and one push of a button, it starts right up. I would recommend it to any one.

Excellent generator.

This generator came well crated and delivered on time. I was impressed with the ease of start up and was amazed at the included maintenance kit. (extra spark plugs, plug wrench, primary and secondary air filter, oil filter). I have not had a chance to power the entire house with the unit but it starts easily and runs strong. Although I do not look forward to a lengthy power outage (which has been more frequent lately in my rural setting) I feel much more at ease having a well built machine as a back up.
