GENERAC 3500 IO

I purchased the 3500 IO back in 2020 in Texas. To date I have 7558.7 hours on the unit, it went through the Big Freeze in Texas, kept my neighbors homes heated during power outages. This unit has had the oil changed every 250 hrs (30W), Lucas upper cylinder gas additive occasionally, a new pull cord at 5800 hrs and a yearly plug change. I recommend this unit for all your uses up to 25 amps, it hasn't let me down. Great unit

Don't be 'one of those guys' while camping

I bought this to use with our 26 ft. camper. Sites with hook-ups are becoming more difficult to get with the increase in post-pandemic campers. I wanted to have full use of my camper but didn't want to listen to (or have my neighbors listen to) a loud, open-frame generator. This generator is SO quiet. It is barely louder than ambient noise at the campground when sitting in our site, and is virtually in-audible by the time you are 50 ft away. Set up was super easy. Connect battery cables. Add oil and good gas (91 octane with zero ethanol is BEST.). Turn on and push start... It is very well built. None of the problems noted in other reviews. My only 'complaints' is the weight and the oil drain design. 100+ pounds seems heavy for a unit this size. But I knew the weight prior to buying it. The oil drain design could use some work. A 4" hose that would slip out through the bottom oil drain port would be a HUGE improvement.

Super quiet and gives the needed power

I haven't had a chance to use my new generator a lot yet. However, the little that I have used it, it is very quiet and has the power to run the lights and tools that I. Need. I love all of the extra features that it has to offer for competitor brands. I would recommend to others.

Made life without power during the huricane considerably more tolerable.

This generator was a blessing. We went from oil lanterns and flashlights to lamps, fans,and TV. We were also able to cook a hot meal with our electric fry pan and pot. The general 2000 started with first pull and was quiet enough for our 3 year old grandson to sleep comfortably. This was a wise investment for a premium quality generator.

Great looking , quiet and affordable generator!

Researched inverter generators on YouTube for hours to find the perfect unit to power my camper at unserved sites. Narrowed my choice down to the Honda EU 3000is or the Generac iQ 3500, but it was the Generac’s cost that made it the easy decision! For being equally (or possibly even more) quiet, 20lbs lighter and having nicer features such as a keyless starting switch, automatic choke, and a display screen for monitoring voltage output and run time to gauge oil changes it knocked it out of the park!! Generac…please make a nice fitted storage cover for this generator! It is a beautiful unit and deserves one! Only one complaint is that the generator started surging right out of the box brand new. I carefully added the included engine oil to the correct level and poured in clean, fresh gas but it needed a carburetor cleaning probably from having residual gas sitting in the carburetor or float bowl during product testing before packaging and sitting in a warehouse for 2 years until I purchased it. Service was covered under warranty, it was just the inconvenience of having to take a brand new unit in and the frustration of fiddling with it myself for 4 hours previous to the service. (I removed and cleaned the carburetor personally, the service centre only removed the float bowl as people are lazy now). ***Be mechanically inclined if you buy this generator. Good service doesnt’ exist anymore. No one will help you. 😑***

Began positive

I have had several carb issues. I worked where we sold Generac generators, and always spoke highly of them. I owned a GP5500 prior w/ few problems. I always kept ethanol free gas or gas w/ Stabil in my IQ3500 . Which purchased 9/2019. I had one carb replacement a year ago ,after a month wait for parts from Generac. It would start but not run and the ECO setting would shutter and shut the engine off. Now it is repeating problems, after only being run on ethanol gas for less than 1 hour. We used it to run the 13.5K A/C or to run heater fan and charge RV batteries. We were able to do one or the other at a time. It was never able to pull the 25 Amp specs.

Good product without much support or info

First off I won this in a raffle, so there is nothing to complain about. However I would like to point out a few things that I feel could be done better by Generac. First off, there are no break in instructions included with the generator. I assume every small engine needs a break in period so I had to look this up myself and perform it. Secondly, why no wheel kit? Yes it’s kinda light but would a wheel kit be hard to make or sell? Sure would be handy, so I’ll have to make one myself. Third, it was quite difficult to find where to register the warranty. You really have to search to find it.

Trouble starting generator

Recently purchased GP2500 generator. Add the oil and fuel as stated in start up guide. The generator fired right up and used it for about 20 minutes running an electric trimmer. Stored it in my shop for month. I got it out last week added fuel. Now it won't start, checked the oil level. Still won't start up. Do you have any things to try before I find an authorized dealer that does repairs.
