My neighbor built an insulated shed. The high pitched noise still hurt my ears.
Supposedly the sound blocking doesn't work great on hard surfaces, like cement or a hard shed base. At the end of the day, 80db vs 70db are still loud as shit and can easily give ya a headache

Is this Inverter Generator? Open Frame is generally used in Inverter but don't see desc
You have it backwards, 90% of potable generators, and most of those are open frame, are regular (non inverter). Inverter style is fairly new to generators and some are now just being larger open framed models.

Old model. $600-$700 was the Costoco warehouse price several years ago. My neighbor bought one. It's not just loud but extremely annoying.
yeah, it's 9400w. it's not an inverter gennny.
Nothing at this price point (or even 2 grand) and that wattage will be quiet.
and they're not fuel efficient either. ​

Loud but less annoying than having no electricity. Most big generators are loud.

O.K. I qualify by saying that in comparison to other conventional generators in this power range which I have used this Firman made a noise which was highly irritating to me. On the other hand of my conventionals I really like my Firman Ultimate 4550. For those who need a ready-made for natural gas gen right now the price is reasonable.

BTW the description is wrong. The TO7571 is 7500 watts on gasoline.

Grabbed one of these from Costco for the same price. I'm considering returning it since Firman is coming out with a tri-fuel closed-frame inverter in 2024.

I was really tempted until reading this review...
"...would not run my two furnaces. i tried balancing the power to only running one furnace and while the blower fan kicks on, the gas heating elements never did. i realize it won't safely power my cooling unit but should be easy for my furnace. i've read something about the total harmonic distortion THD too high so the furnace might have a safety feature due to the dirty power signature. it does fine with everything else..."

My biggest reason for getting a generator would be for powering my (oil) heat furnace and my water well pump. I didn't think "dirty" power affected those things like they do with computers and other small electronics.
Please inform me before this deal goes away.

edit NVM. Sorry, I didn't realize that shipping was not an option.

I would say it's as fuel efficient as any other in this size/price point. Even better when using on natural gas!

Don't worry about that review. That is user error. You can't just buy a generator and "try" it out with some large unknown load and expect it to work. First, make sure you understand the generator ratings. The advertised power(starting watts) usually is not what you can use full time(running watts). You have to read the description to see which one is actually used in the advertising.

Second, become familiar with the electrical ratings of the large loads you are interested in running. A lot of times, there should be a nameplate with ratings on the equipment you are interested in running. Example of what you need: volts: 120v 12amps. Using Power=Voltage x Current, you can add up your loads. For your case, add up your 2 loads of interest to find your minimum generator size. Add about 15% on to it just to be safe. Once you have this number, any generator larger will cover your needs.

Third thing,and this one kinda sucks, you have to consider how you get your power out of the generator. Do you use one plug into an electrical panel or multiple cords direct to you load? Whichever connection you choose has to be able to supply that power to the load. For example, if you use and outlet on the generator rated for 120volts 20 amps= 2400watts, you can never get more out of that outlet than it is rated, and likely slightly less as it's breaker may trip at a slightly lower value. A lot of times, the big 240v plug can't even carry the full capacity of the generator.

In summary, get your power ratings of interest. Add about 15%, check your chosen gen plugs power rating you will use to get the power out of the generator and see if it will carry your expected load.

If you knew you needed and big gen to run your very limited whole house, I wouldn't get anything smaller than an approximately 9200 RUNNING WATTS.

Addressing the dirty power aspect, some very smart electronics may give an error which equates to some kind of power error. I think I had one on my heat pump water heater one time. I haven't looked enough into it to see if it was THD or more likely a lower voltage or frequency than it liked. Voltage and frequency will sag more on heavily loaded gens. It might have been a grounding issue since I didn't have the generator ground tied in. The voltage and frequency can be slightly adjusted based on the rpm of the gen motor which you should never mess with unless you know what you are doing.
