I never had trouble with a Generac and currently own a 24Kw system on my farm. I have had one Kohler system and 4 Generac systems. (I was in the Army, we moved a lot). They are "Life Insurance."
The Kohler generator does not need a separate conversion kit to have it run on propane. The come from the factory setup for Natural gas and the setup it up for propane is very simple. Install a reducer on the already installed gas regulator and unplug two wire right next to the regulator and that’s it it’s ready for propane. Also in my experience the Kohler generators have been extremely heavy duty and more relabel than the generacs.
Most generators come with a standard kit to switch from natural gas to lp. That's because most units are factory test run on natural gas and ng is available in more locations. Most times it's a matter of changing an orifice or moving a jumper wire or turning a few screws,or a combo of all 3.
I’ve been hearing Kohler and Cummins are more reliable and run longer with fewer problems. Is this really true? I’m going to decide very soon which to get as my Mom is older and needs special care regarding O2 machines as she has CHF and other pulmonary issues plus we are concerned about blackouts. Bad times are coming.
Not sure where to start, which is about where this incorrect info in the video leads us. Both companies offer remote monitoring via cell phone. I believe Generac was first to include it as standard. Both will run on NG or propane WITHOUT a separate conversion kit. Neither will run on gasoline. Matter of fact, I don't believe there's any UL listed standby sets running on gasoline.

I have used a Kohler 15kw water cooled propane gen for 13 years off grid to supplement my solar array. Elton is correct on all counts. If buying a gen you must consider the run time you will need. Air cooled gens are about 8hrs tops whereas water cooled will run indefinitely and if you are off grid, air cooled is probably not the right choice.
@@dunningkruger3774 ... if you are off grid you should stop comparing brands and look at specs that matter. Liquid cooled and 1800 RPM will be the benchmark... and most companies have gotten away from that in units under 25 KW, due to the demand for cheaper homeowner units. You got on the bandwagon with the last run of those better / smaller units.
@@rupe53 I think you meant 1800 RPM :)) And you are precisely correct -- not at all a fair comparison, there's a world of difference between 1800 RPM/liquid-cooled and 3600 RPM/air-cooled generators. Speculation on my part, but I suspect a gen that's rated off-grid is built to higher specs than standby units, and as I understand, are not warranted but for a year. In response to Dunning Kruger, "air cooled gens are about 8hrs tops"...I installed a 22kW propane-fueled gen to a 400A service with two 200A ATS's in February 2021; it ran continuously and flawlessly for nearly three days during the "Interstate I-95 56-Mile Snow Magedon" incident.
I went with a Kohler and have had no complaints. After the install, I asked one of the techs about his opinion of the different brands they sold. I asked him what he thought about Generacs. He leaned in (to be out of earshot from his boss) and said, "they're junk - even though we sell and service them"). The Kohler is not high maintenance as someone commented. I touch mine only once a year - to change the oil (assuming no MAJOR outages). Changing the oil is quick and simple. Every few years I put in a new battery. That's it.
Authorized Generac Dealer This video is so full of errors Generac does an automatic test/diagnosis 5 min not 20 Generac has remote monitoring (Wi-Fi/LTE) options which allow troubleshooting/possibly fixing it without going on site Generac is also commercial grade engine 999cc Generac is built in the USA Generac has a very high motor starting capability able to AC/other big loads without dropping power to other circuits Generac has an aluminum body so it doesn't rust Generac can also be 18" off of house Generac also has a 24kw air cooled while kohler's biggest air cooled is only a 20kw (you are comparing a liquid cooled kohler to a Generac air cooled in your comparison sheet) Generac has more dealers nationwide making them more accessible 8 out of 10 home standby generators are Generac Please do your research when making a comparison video like this!
Generac and Kohler dealer chiming in, all what you say is true however I have twice as many Kohlers in my loop than Generacs and most of the failures happen on the Generacs, most with less than 200 hours. Also noteworthy that years ago I had two no starts from the factory (both Generac), one bad control board and one that had a wire that was not crimped into its connector. This is why I never push Generac, I don't want to devote my life to trying to fix them.
As a tech I'm not a fan of generac. As a tech who entered the field before y2k, I was brought in by Kohler, and I really like their product. Or,should say,liked their product. The plastic housing for the home standby unit puts me off. Look at a plastic lawn chair after 8yrs sitting outside. The older stuff is great though. In this case I'd have to pick the Kohler. Generac makes parts too proprietary and too expensive. Price out a new control board for one. Kohler's aren't cheap either. Another option is a Briggs ,the latest one is about as quiet as a Kohler and imo definitely better quality than a generac but a step under the Kohler with the solid lifters still requiring valve adjustments.
Quiet test is nice if you like your engine to make tons of moisture and turn the oil white and make "cottage cheese" , as a tech I turn that feature off in order to save the engine.
You are correct. The quiet test is at best a gimmick, at worst it can cause long term engine damage due to not "boiling" off the water that tends to accumulate in the engine oil. This because it doesn't get hot enough, because it doesn't run long enough to boil the moisture out of the oil.
Re: Kohler; The description says that the “triple fuel” includes LP and Propane. So I suppose that the term should be changed to “double fuel” since LP and Propane is nothing more than two terms for the same thing.
Kohler have way less dealers and are high maintenance. Generac has the wifi feature now also. I hear siemens also makes a whole house but again try to find a dealer that services siemens was a headache.
I install generators. All I can say is DO YOUR HOMEWORK!!!! or you WILL be a very unsatisfied owner. It’s not any one name brand although some have more issues than others. With the new “smart” generators, far more problems have been creeping up. You buy a generator for a very important purpose. Not to show off to your friends on your phone. If you don’t get.a service contract and are not mechanically inclined, there will be issues.
So Koehler is better….because smart phone app, really? And would you compare using one with kilograms and the other with lbs. Conversion is a google click away??? Suggest spending more than a few minutes on research.
What a bunch of gibberish! I'm more confused now than I was before I watched this. I think this guy would make a good politician! Talk for almost 5 minutes and give inaccurate false information
Wow, as a gas contractor who does a lot of generator 5kw-200kw installs, this guy has no idea what he’s talking about. Kohler arrives on site ready to go dual or tri fuel. You’re not converting anything on the field. So he lost me at the first point.
Well, not exactly. ALL natural gas/propane capable generators come from the factory set for natural gas. So, for propane they do have to have a "field" conversion. Not hard, but still has to be done for proper operation.
Don’t quite understand where this video’s owner got his technical data. Please go back, do a better research job and correct all your info. Most glaring is the asserted need for an LP/NG conversion kit. Not necessarily true!
WOW ,very misleading, Generac has a 26 kw generator .I have been selling and installing both brands for over 30 years. They are equal in quality you are showing a Bias. I suspect you work or are a Kohler dealer.
@old timer, glad someone of your caliber responded. This is the worst "comparison" of the two I've ever seen. Absolute outdated data and farcical statements. Take this trash down.
@@nicktheofilos7759 Could it be that the higher ratio of Generac failures is due to a higher ratio of homeowner installs? Over the years that's been my experience, both actual and hearsay. Out of every Generac I've installed most outran the warranty period. As for which is more heavy-duty I think it's a tossup. The engine builds are quite similar in design specs and build. On the other hand, given that I've not installed Kohler that might not be a fair evaluation.
@@wellcraft2136 The homeowner aspect hasn't played a huge part in my experience however it is a consideration I had not given much thought to. There are a lot of things I like about Generac better particularly when it comes to installation. However I have had two Generacs come from the factory non operational, so that kinda leaves a bad taste in my mouth. Finally Kohler has hydraulic lifters eliminating the need to adjust valve lash, so for those reasons I tend to push Kohler for new installs but at the end of the day will install whatever the customer prefers.
@@benherbst6822 ... NEC is national and calls for outside installation at least 5 feet from any door, window, or exterior opening of the home. (drier vent, Jeniar vent, fresh air / fireplace, crawlspace louver, etc)
You are doing a caparison, But you are showing a lot of industrial generators. You need to stick to one model to compare and only show that model. POORLY designed comparison video! As a dealer and installer for generators, I agree, The Kohler is better and Gives you fully user friendly controller, that can be programmed by the end user. And Kohler give you parts and service ASAP after the sale.
This video provided some good information. However, I disagree with your recommendation. Because, my next home in Southern California will have a "Generac" Natural Gas Powered back-up system (smile...smile).
Generacs used to be really good, but ever since they partnered with Home Depot to sell their generators, I've seen the quality drop off. The biggest thing we've seen is a drop in quality control (loose connections, screws missing, panels misaligned, wiring not installed properly, etc.) basically it seems like they're trying to build them as fast as possible with as few people as possible.
Maybe you should do a review on a 1978 Pinto vs a 2022 Corvette. Comparing a liquid cooled to an air cooled is apples to oranges. Too many falsehoods in this terrible comparison.
I have just installed a 24 kw Generac and after researching Kohler. Generac and Briggs and Statton home standby generators the one thing I know 100% is that the cost of Generac is 20% cheaper and the differences are very minor between the 3. ,
To the untrained eye, you see no difference. If all you look at is $ per kilowatt, you are not looking at the right place. Let me engage you some, look on the generac cabinet inside and notice a decal that says words to the effect of "maximum imbalanced current load is 50%". On the Kohler machine the decal is also there, it says maximum unbalanced load rating is 100%. Most don't know what that means. It basically means that a Kohler can handle 100% of its rated load on one set of windings, (there are two sets on a 3600 RPM machine) Where as the generac can only load its windings to half load. It means that the Kohler has more copper in its windings of a larger size, and a stronger voltage regulator and is not as effected by the heat generated by the load on the windings. So, a higher build quality. Check the shipping weights for each similarly sized machine, see which is the heaviest-which one has a better engine, which one has more copper in its load windings? These are not the only difference. Greater oil capacity is another. But, to be sure it is less expensive for a reason. Tell me, where is your generac engine made? Not assembled, but cast, bored and machined. You know, made.
There are tons of generac dealers with in stock parts compared to kholer dealers but each market is different.. That's why I chose generac and I'm very happy. Buy the extended warranty
I have had both. I bought generac first. had engine surging and misfires first year. I called customer service and they accused me of faulty Maintenace. They were horribly rude and basically said my warranty was void! I would NEVER buy anything from any business associated with generac. I have had a Kohler since 2012. Unlike the generac, it has actually powered my house during outages.
I have genrac and and it all depends on where you live I live in a place where we have very bad storms and it cuts in fast and help with power outages and I have a 3 bedroom 3 bathroom house 🏡 so it works fine
Generac and Kohler authorized service dealer here- so much wrong information on both brands they both have the pros and cons but it f your looking for reliable and service friendly air cooled for the average consumer go with Kohler not generac
I have a Generac 22 Kw its been noting but a problem, it failed me twice when I need it most. I live in Florida and the last two hurricanes we had Irma and Ian it ran 6 hour the first time then quit the second time it ran 8 hour the quit . Its been two weeks now science the tec came out to look at it still waiting for the parts as of this post. A 7ooo.oo peace of crap.
@@savedby_grace6110 Your best bet would be to by a portable generator like I just did. O and by the way Generac will not honor my maintenance agreement which I paid an extra 700.00 for.
Who ever made this video knows nothing about generators. The engine used depends upon the size generator you buy. And that 18" to your home? Bull shit! Code says 5 feet to any burnable surface. I've sold and serviced generators for over 25 years. The Kohler is better. That short exercise time on the generac actually causes water condensation in the oil!
Nope. 18" is it to non combustible siding, masonry, etc. Now both Generac and Kohler are 3rd party certified for that installation. But, yes the kohler is better.
Use caution when buying a Kohler, their dealer service network is nowhere to be found in many areas of the country and in areas where their might be one they can be a bit touchy if you didn't buy from the when it comes to service, I have a 12RESV unit 1/1/2 years old 100 hours running time that has failed and because I had a local electrician install it the local Kohler dealer told me they no longer will do service calls on units they did not sell and install, so basically no matter what Kohler offers as a warranty it's useless in my situation so I now own a nice Yard ornament....Choose wisely
Another major factor you did not address (maybe because Generac takes this one hands down?) is the service and parts network. See how many Generac dealers there are across the US, and where they are (big city vs rural areas), and then see about Kohler. It is much easier to find local help for Generac than Kohler, because they have a much more extensive support network.
Thank you for pointing this out. We should never take the service network for granted. Here is the Generac Dealer locator: www.generac.com/dealer-locator Here is the Kohler Dealer locator: kohlerpower.com/en/engines/dealers
Generac will let almost ANYONE be a sales or a servicing dealer, or both. A lot of plumbers and electricians sign up for the additional revenue stream, as installation is where the easy money is made. Repairs...well not as many servicing dealers.
The two brand are absolutely from two different dimensions. Generac has a nick name Genecrap, which typically looks ok but that is where it ends. Kohler on the other hand is a reliable brand used on commercial and industrial projects widely. These two cannot be compared, it is a different scale units
@@talusranch990 yeah, and this was the reason for them to enter generating business. Toilets and faucets in remote locations did not sell well without a power supply and water pumps
@@talusranch990 and Kohler makes faucets and bathtubs plus many other things and my Mom remodeled her home with dad hiring the contractor and they put all Kohler products in back in the later 70s and everything lasted very well. The bathtub is beautiful and real cast iron too. Not this cheap crap today. We have Kohler standby and it’s good.
@@ChatGPT1111 ... Generac has the price point. IOW, best bang for the buck. My comparison is they are like a Chevy.... everyone can afford one. The Kohler is (can be?) longer lasting but in reality, all is similar when it comes down to function.
What does that even mean? They both run on 3600rpm. Both adjust the speed according to the load and fuel type (LP gives more power). And they both can give more than shown in specs. kohler wants you to check oil every 8hra of running, Generac - 24hrs. Both body cases are aluminum. And for the moment of me putting this comment, generac has 26kw aircooled generator that will allow plus one more ac (ish). Evo 2 controller and interface is much easier than Kohler. I haven’t work on Kohler but saw them, troubleshooting books and so. Like generac for the simplicity of it. Tbh both will work good in perfect scenario, like weather, fuel pressure and maintenance so choose whichever you will get the best service in your area.
You are confused in your description. If you want to look at max horse power at a given RPM, then you might be on to something. But all two pole air cooled engines run at 3600 RPM to create a 60 hertz sine wave. They both are governed to maintain a 3600 RPM at varying loads by varying the fuel supply quantity to maintain 3600 RPM to maintain a 60 cycle wave form.
As a generac certified dealer and technician can only say that this video is false. With the hundreds of generators we installed and serviced only a few (2 recalls) had some factory issues that been taken care of with no delay. Little things happen here and there if something is done wrong by the installer (wrong fuel or oil pressure) or the customer (irrigation system hitting the unit). But overall we have tons of positive feedback’s especially in SWFlorida, where we have bad grid and hurricanes like Irma, Ien, and fires, when they cut the power for hrs or days putting the fire down. I have seen a lot of bad installations by “i am electrician, I can do anything”, that ended up having issues, but it was all resolved mostly by the warranty. Also generac has aluminum body with powder coating. And now we are installing 26kw, which is 109A ish load compare to 83,5A 20kw. 25A more which is significant
I love my 16kw Natural Gas Generac. I have a 10 year warranty already 6 years into ownership. Even when its 20 below zero it starts right up. Even when power goes off and on 20 tines in 2 days...no issues. Power is clean and I am so confident it keeps my hot tub going as well so it wont freeze. Now Inget mobillink messages whenever it runs or has an issue. I have never lost anything that runs on electricity because the power coming from it is that good. I also have a 7kw on grid solar system and this works flawlessly with it. I am sooo happy with this Generac generator and Generac whole house switch I highly recomend it.
As a generator tech who has serviced both Kohler and Generac, Generac is hands down the best unit. Your video was very very inaccurate. G force engines are in air cooled units not the liquid cooled. Most of generac liquid cooled engines are Ford Windsor engines. The generac unit does exercise once a week. You kept also saying they run off gasoline. None of those units run off of gasoline. Either Natural Gas or Liquid Propane. Gasoline is completely different. Generac has an all aluminum body while Kohlers are just a cheap plastic and fiberglass. There is a reason why 80 percent of home standby generators are GENERAC not Kohlers. Buy a generac!!!!!
LOL - Let me guess - you're employed by Generac or sell them, but not Kohler, right? Because you are so out of step with the opposite opinion which is held by the vast majority of your fellow techs.
Changing oil and filters i.e. "servicing" generators is not the same as troubleshooting and repairing. I have "serviced" a dozen different brands, and some are definitely better than others. And while generac has improved some, they still have a ways to go in quality. You harp about the poly enclosure of the Kohler as being cheap, how long would you think a steel/aluminum enclosure would last in a salt air environment? That is to say, you can buy a "poly" enclosure for areas that need it, or an aluminum enclosure if that is your preference. Both are available.

Just FYI: as Long as you're running the discrepancies by your video team, you might want to let them know in the main TH-cam title of this video they misspelled Generac... (its not Gencera)
I have used a Kohler 15kw water cooled propane gen for 13 years off grid to supplement my solar array. Elton is correct on all counts. If buying a gen you must consider the run time you will need. Air cooled gens are about 8hrs tops whereas water cooled will run indefinitely and if you are off grid, air cooled is probably not the right choice.
@@dunningkruger3774 ... if you are off grid you should stop comparing brands and look at specs that matter. Liquid cooled and 1800 RPM will be the benchmark... and most companies have gotten away from that in units under 25 KW, due to the demand for cheaper homeowner units. You got on the bandwagon with the last run of those better / smaller units.
@@rupe53 I think you meant 1800 RPM :)) And you are precisely correct -- not at all a fair comparison, there's a world of difference between 1800 RPM/liquid-cooled and 3600 RPM/air-cooled generators. Speculation on my part, but I suspect a gen that's rated off-grid is built to higher specs than standby units, and as I understand, are not warranted but for a year. In response to Dunning Kruger, "air cooled gens are about 8hrs tops"...I installed a 22kW propane-fueled gen to a 400A service with two 200A ATS's in February 2021; it ran continuously and flawlessly for nearly three days during the "Interstate I-95 56-Mile Snow Magedon" incident.
I went with a Kohler and have had no complaints. After the install, I asked one of the techs about his opinion of the different brands they sold. I asked him what he thought about Generacs. He leaned in (to be out of earshot from his boss) and said, "they're junk - even though we sell and service them").
The Kohler is not high maintenance as someone commented. I touch mine only once a year - to change the oil (assuming no MAJOR outages). Changing the oil is quick and simple. Every few years I put in a new battery. That's it.
Generac is JUNK.
Authorized Generac Dealer
This video is so full of errors
Generac does an automatic test/diagnosis 5 min not 20
Generac has remote monitoring (Wi-Fi/LTE) options which allow troubleshooting/possibly fixing it without going on site
Generac is also commercial grade engine 999cc
Generac is built in the USA
Generac has a very high motor starting capability able to AC/other big loads without dropping power to other circuits
Generac has an aluminum body so it doesn't rust
Generac can also be 18" off of house
Generac also has a 24kw air cooled while kohler's biggest air cooled is only a 20kw (you are comparing a liquid cooled kohler to a Generac air cooled in your comparison sheet)
Generac has more dealers nationwide making them more accessible
8 out of 10 home standby generators are Generac
Please do your research when making a comparison video like this!
I have passed the feedback to the video team. Thankyou.
Agreed. I have a 24kw and can monitor it from my cell phone. This video is giving misinformation.
Generac and Kohler dealer chiming in, all what you say is true however I have twice as many Kohlers in my loop than Generacs and most of the failures happen on the Generacs, most with less than 200 hours. Also noteworthy that years ago I had two no starts from the factory (both Generac), one bad control board and one that had a wire that was not crimped into its connector. This is why I never push Generac, I don't want to devote my life to trying to fix them.
I am glad you commented. WAY to much inaccurate information.
Kohler now has a 26kW (On LP Gas) air cooled.
My Generac has a valve on the gas inlet line. Turn it one way for propane, the other way for natural gas. Very simple and no kit required.
Very cool :)
Don't forget to change the controller to the respective fuel supply when you do.
As a tech I'm not a fan of generac. As a tech who entered the field before y2k, I was brought in by Kohler, and I really like their product.
Or,should say,liked their product. The plastic housing for the home standby unit puts me off.
Look at a plastic lawn chair after 8yrs sitting outside.
The older stuff is great though.
In this case I'd have to pick the Kohler.
Generac makes parts too proprietary and too expensive.
Price out a new control board for one.
Kohler's aren't cheap either.
Another option is a Briggs ,the latest one is about as quiet as a Kohler and imo definitely better quality than a generac but a step under the Kohler with the solid lifters still requiring valve adjustments.
Thanks for the pro tips :)
Kohler's new RCA series generators have aluminum housings. The RESA series still have the composite housings.
I bought a Kohler home generator because I work with a tech and he highly recommended Kohler. He said Generac was junk in opinion.
The valve adjustment is the deciding factor for me I don't want my vital parts being exposed to dust etc. so I'm going with the Kohler
Quiet test is nice if you like your engine to make tons of moisture and turn the oil white and make "cottage cheese" , as a tech I turn that feature off in order to save the engine.
Thanks for the pro tips :)
You are correct. The quiet test is at best a gimmick, at worst it can cause long term engine damage due to not "boiling" off the water that tends to accumulate in the engine oil. This because it doesn't get hot enough, because it doesn't run long enough to boil the moisture out of the oil.
Re: Kohler; The description says that the “triple fuel” includes LP and Propane. So I suppose that the term should be changed to “double fuel” since LP and Propane is nothing more than two terms for the same thing.
Good catch. Thank you for the feedback.
I have a 27 year old generac no problem
Glad you having a good experience
I actually like the older generacs, easier to repair and less expensive too.
I would never buy a generac product. Professionally, I’ve had nothing but problems with generac products.
Thank you for sharing your experience.
Kohler have way less dealers and are high maintenance. Generac has the wifi feature now also. I hear siemens also makes a whole house but again try to find a dealer that services siemens was a headache.
Thanks for watching.
their units need no more maintenance as a generac.
The Siemens, Eaton & Honeywell branded generators are all made by Generac.
"Siemens" is a generac.
I install generators. All I can say is DO YOUR HOMEWORK!!!! or you WILL be a very unsatisfied owner. It’s not any one name brand although some have more issues than others. With the new “smart” generators, far more problems have been creeping up. You buy a generator for a very important purpose. Not to show off to your friends on your phone. If you don’t get.a service contract and are not mechanically inclined, there will be issues.
Thank you for sharing :)
So Koehler is better….because smart phone app, really? And would you compare using one with kilograms and the other with lbs. Conversion is a google click away??? Suggest spending more than a few minutes on research.
Thank you for the feedback we will let the video team know.
Kohler Generators are more reliable
And more heavy duty
Thanks for watching.
I would like to see Generac and Champion who's the best.
thank you for the idea :)
Kohler home standby generators DO NOT run on gasoline. The portables do but gasoline isn't even an option for HSB. NG or propane only.
What a bunch of gibberish! I'm more confused now than I was before I watched this. I think this guy would make a good politician! Talk for almost 5 minutes and give inaccurate false information
Have passed the feedback back to the video team.
Wow, as a gas contractor who does a lot of generator 5kw-200kw installs, this guy has no idea what he’s talking about. Kohler arrives on site ready to go dual or tri fuel. You’re not converting anything on the field. So he lost me at the first point.
Thank you for the feedback.
Well, not exactly. ALL natural gas/propane capable generators come from the factory set for natural gas. So, for propane they do have to have a "field" conversion. Not hard, but still has to be done for proper operation.
@@bobbygene8274 wrong! Nice try but wrong.
Don’t quite understand where this video’s owner got his technical data. Please go back, do a better research job and correct all your info. Most glaring is the asserted need for an LP/NG conversion kit. Not necessarily true!
We are working on an update of this video. Thank you for the feedback.
WOW ,very misleading, Generac has a 26 kw generator .I have been selling and installing both brands for over 30 years. They are equal in quality you are showing a Bias. I suspect you work or are a Kohler dealer.
Thanks for the feedback.
@old timer, glad someone of your caliber responded. This is the worst "comparison" of the two I've ever seen. Absolute outdated data and farcical statements. Take this trash down.
Agree partially, I am also a dealer to both but have many more failures from the Generacs out of a smaller sample size.
@@nicktheofilos7759 Could it be that the higher ratio of Generac failures is due to a higher ratio of homeowner installs? Over the years that's been my experience, both actual and hearsay. Out of every Generac I've installed most outran the warranty period. As for which is more heavy-duty I think it's a tossup. The engine builds are quite similar in design specs and build. On the other hand, given that I've not installed Kohler that might not be a fair evaluation.
@@wellcraft2136 The homeowner aspect hasn't played a huge part in my experience however it is a consideration I had not given much thought to. There are a lot of things I like about Generac better particularly when it comes to installation. However I have had two Generacs come from the factory non operational, so that kinda leaves a bad taste in my mouth. Finally Kohler has hydraulic lifters eliminating the need to adjust valve lash, so for those reasons I tend to push Kohler for new installs but at the end of the day will install whatever the customer prefers.
The “Best one” is the one that breaks down the LEAST .
Thanks for watching.
Which is??
does a 24kw really weigh 1200lbs? that seems extreme
The Kohler does yes. kohlerpower.com/en/residential/generators/product/24rcl
The Kohler 24 liquid-cooled is heavy. Liquid-cooled units are *much* heavier than air-cooled ones.
My neighbor installed a Generac in his garage we live in a townhouse community in Florida. Is there a law against this?
We are unaware of local laws. Check your local ordinance codes. Thanks for watching.
Nec says all equipment shall be installed to manufacture spec. All generaters are for external installation only.
Pretty much a sure thing that it is a death trap now. But I suspect you’re just joking about such obvious matters.
@@benherbst6822 ... NEC is national and calls for outside installation at least 5 feet from any door, window, or exterior opening of the home. (drier vent, Jeniar vent, fresh air / fireplace, crawlspace louver, etc)
Better to ask - is there a law against stupidity.
How much would it cost to run a Kohler generator
I gave the video a thumbs-down just 15 seconds into it. They don't run on gasoline, they run on either NATURAL GAS, or liquid propane (LP).
You didn't mention the prices of the units
Thank you for the feedback
You are doing a caparison,
But you are showing a lot of industrial generators. You need to stick to one model to compare and only show that model.
POORLY designed comparison video!
As a dealer and installer for generators, I agree, The Kohler is better and Gives you fully user friendly controller, that can be programmed by the end user.
And Kohler give you parts and service ASAP after the sale.
We are working on an update for this video. Thank you for the feedback.
LP and propane are the same thing. Did you mean LNG, LP, gasoline?
This video provided some good information. However, I disagree with your recommendation. Because, my next home in Southern California will have a "Generac" Natural Gas Powered back-up system (smile...smile).
Thanks for watching
How did you come to that conclusion?
when if fails we will be reading your post about how it failed on our pc's in our homes powered by a kohler.
Stopped watching when you talked about residential generators and showed pictures of commercial generators. Not even close to being the same.
Thank you for the feedback.
The information in this video is not very accurate.
We are working on an update for this video. Thank you for the feedback.
What's better, buy the generator through the company or the Homedepot?
Whichever is closer to you should work. Thanks for watching.
Yea, this video is off target..
We have let the video team know about the errors reported in this production. We will have an updated version out soon.
Generacs used to be really good, but ever since they partnered with Home Depot to sell their generators, I've seen the quality drop off. The biggest thing we've seen is a drop in quality control (loose connections, screws missing, panels misaligned, wiring not installed properly, etc.) basically it seems like they're trying to build them as fast as possible with as few people as possible.
Not a lot correct in this video… gasoline? You mean nat gas.. LP = Liquid Propane
Generacs have too many issues.
Thanks for watching.
Maybe you should do a review on a 1978 Pinto vs a 2022 Corvette. Comparing a liquid cooled to an air cooled is apples to oranges. Too many falsehoods in this terrible comparison.
Thank you for the feedback.
Sounds like you were biased, you should’ve just picked the reasons why you prefer Kohler over Generac, not a fair comparison at all!
There are so many false statements I don’t know where to start.
This video looks like it was made by someone who's never touched either generator.
Every review from Lowes or Home Depot Of Generac Generators are Bad!
That's strange; as of June 2023 all of the HD reviews are 4+ stars. E.g., the Guardian 22,000-Watt has 4.8/5 stars with more than 2,000 ratings.
Terrible information. You’re wrong on many things.
I know people who bought power equipment with Kohler engines and it is complete junk. Generac is definitely the way to go.
Thanks for watching.
Well,my 45KW Kohler has a 6cyl ford engine.
Kohler command pro engine or courage engine big differance between the 2 engines
I have just installed a 24 kw Generac and after researching Kohler. Generac and Briggs and Statton home standby generators the one thing I know 100% is that the cost of Generac is 20% cheaper and the differences are very minor between the 3. ,
Always good to be prepared.
That 20% comes from somewhere.
To the untrained eye, you see no difference. If all you look at is $ per kilowatt, you are not looking at the right place. Let me engage you some, look on the generac cabinet inside and notice a decal that says words to the effect of "maximum imbalanced current load is 50%". On the Kohler machine the decal is also there, it says maximum unbalanced load rating is 100%.
Most don't know what that means. It basically means that a Kohler can handle 100% of its rated load on one set of windings, (there are two sets on a 3600 RPM machine) Where as the generac can only load its windings to half load. It means that the Kohler has more copper in its windings of a larger size, and a stronger voltage regulator and is not as effected by the heat generated by the load on the windings. So, a higher build quality. Check the shipping weights for each similarly sized machine, see which is the heaviest-which one has a better engine, which one has more copper in its load windings?
These are not the only difference. Greater oil capacity is another. But, to be sure it is less expensive for a reason. Tell me, where is your generac engine made? Not assembled, but cast, bored and machined. You know, made.
There are tons of generac dealers with in stock parts compared to kholer dealers but each market is different.. That's why I chose generac and I'm very happy. Buy the extended warranty
Thanks for watching. Yes people can find all the Generac dealers here: www.generac.com/dealer-locator
guess you planing on your generac to break down alot LMAO , good luck there junk
I have had both. I bought generac first. had engine surging and misfires first year. I called customer service and they accused me of faulty Maintenace. They were horribly rude and basically said my warranty was void! I would NEVER buy anything from any business associated with generac. I have had a Kohler since 2012. Unlike the generac, it has actually powered my house during outages.
Thank you for sharing your experiences.
If your regulators will not correctly it will running like crap as a Vanguard engine same as Generac
I have genrac and and it all depends on where you live I live in a place where we have very bad storms and it cuts in fast and help with power outages and I have a 3 bedroom 3 bathroom house 🏡 so it works fine
Generac top wattage is now 24kw. The one you compared is last year’s model. Edit: Now they have a 26KW!
Thank you
How long can you continuously run them with out having trouble with them?
As long as there is a fuel supply of gas, natural gas or propane, a well-maintained backup generator will keep running.
generac, about 5min
Generac and Kohler authorized service dealer here- so much wrong information on both brands they both have the pros and cons but it f your looking for reliable and service friendly air cooled for the average consumer go with Kohler not generac
Thanks for sharing.
I have a Generac 22 Kw its been noting but a problem, it failed me twice when I need it most. I live in Florida and the last two hurricanes we had Irma and Ian it ran 6 hour the first time then quit the second time it ran 8 hour the quit . Its been two weeks now science the tec came out to look at it still waiting for the parts as of this post. A 7ooo.oo peace of crap.
Thanks for the information. If you were to do it again, which would you buy? Fellow Floridian:)
@@savedby_grace6110 Your best bet would be to by a portable generator like I just did. O and by the way Generac will not honor my maintenance agreement which I paid an extra 700.00 for.
Yeah would never buy a Generac after seeing so many fail in the field
thanks for watching
Who ever made this video knows nothing about generators. The engine used depends upon the size generator you buy. And that 18" to your home? Bull shit! Code says 5 feet to any burnable surface. I've sold and serviced generators for over 25 years. The Kohler is better. That short exercise time on the generac actually causes water condensation in the oil!
Thanks for the feedback.
Nope. 18" is it to non combustible siding, masonry, etc. Now both Generac and Kohler are 3rd party certified for that installation. But, yes the kohler is better.
What the hell are you talking about? LP, Gasoline & Propane? LP is Propane and Generacs do not use gasoline.
Video team is working on an updated video to correct our errors.
@@trimthatweed-yourgardening2662 you should take it down until new video ready. Run it by some experts for pre release review.
Use caution when buying a Kohler, their dealer service network is nowhere to be found in many areas of the country and in areas where their might be one they can be a bit touchy if you didn't buy from the when it comes to service, I have a 12RESV unit 1/1/2 years old 100 hours running time that has failed and because I had a local electrician install it the local Kohler dealer told me they no longer will do service calls on units they did not sell and install, so basically no matter what Kohler offers as a warranty it's useless in my situation so I now own a nice Yard ornament....Choose wisely
Another major factor you did not address (maybe because Generac takes this one hands down?) is the service and parts network. See how many Generac dealers there are across the US, and where they are (big city vs rural areas), and then see about Kohler. It is much easier to find local help for Generac than Kohler, because they have a much more extensive support network.
Thank you for pointing this out. We should never take the service network for granted.
Here is the Generac Dealer locator: www.generac.com/dealer-locator
Here is the Kohler Dealer locator: kohlerpower.com/en/engines/dealers
that's bc they brake all the time, that's why there's so many people that are willing and know how to fix it..
So, does Generac need all those service outlets? Could this imply that Kohler does not need that much service/warranty attention?
They have more parts available because they break down more and always need parts.
Generac will let almost ANYONE be a sales or a servicing dealer, or both. A lot of plumbers and electricians sign up for the additional revenue stream, as installation is where the easy money is made. Repairs...well not as many servicing dealers.
The two brand are absolutely from two different dimensions. Generac has a nick name Genecrap, which typically looks ok but that is where it ends. Kohler on the other hand is a reliable brand used on commercial and industrial projects widely. These two cannot be compared, it is a different scale units
Thanks for watching.
Kroler makes toilets. Let's not forget that bud.
@@talusranch990 yeah, and this was the reason for them to enter generating business. Toilets and faucets in remote locations did not sell well without a power supply and water pumps
@@talusranch990 and Kohler makes faucets and bathtubs plus many other things and my Mom remodeled her home with dad hiring the contractor and they put all Kohler products in back in the later 70s and everything lasted very well. The bathtub is beautiful and real cast iron too. Not this cheap crap today. We have Kohler standby and it’s good.
@@AY-cj9kp Kohler entered the generator business 100 years ago to supply electricity to farmers.
Kohler > generac
Thanks for the feedback :)
Which is why Generac sells about 10x as many units, word of mouth.
@@ChatGPT1111 ... Generac has the price point. IOW, best bang for the buck. My comparison is they are like a Chevy.... everyone can afford one. The Kohler is (can be?) longer lasting but in reality, all is similar when it comes down to function.
@@ChatGPT1111 Justin Bieber sells out concerts, that doesn't mean I'm going.
@@nicktheofilos7759 who is she?
Keep in mind that Generac's 24KW rating is at 100% engine rpm. Kohler's 22KW rating is at 80% rpm - which enhances engine longevity.
What does that even mean? They both run on 3600rpm. Both adjust the speed according to the load and fuel type (LP gives more power). And they both can give more than shown in specs. kohler wants you to check oil every 8hra of running, Generac - 24hrs. Both body cases are aluminum. And for the moment of me putting this comment, generac has 26kw aircooled generator that will allow plus one more ac (ish). Evo 2 controller and interface is much easier than Kohler. I haven’t work on Kohler but saw them, troubleshooting books and so. Like generac for the simplicity of it. Tbh both will work good in perfect scenario, like weather, fuel pressure and maintenance so choose whichever you will get the best service in your area.
You are confused in your description. If you want to look at max horse power at a given RPM, then you might be on to something. But all two pole air cooled engines run at 3600 RPM to create a 60 hertz sine wave. They both are governed to maintain a 3600 RPM at varying loads by varying the fuel supply quantity to maintain 3600 RPM to maintain a 60 cycle wave form.
@@josephsednev Checking the oil on any air cooled is advisable. How often is up to the conditions of the engine and the customer.
As a generac certified dealer and technician can only say that this video is false. With the hundreds of generators we installed and serviced only a few (2 recalls) had some factory issues that been taken care of with no delay. Little things happen here and there if something is done wrong by the installer (wrong fuel or oil pressure) or the customer (irrigation system hitting the unit). But overall we have tons of positive feedback’s especially in SWFlorida, where we have bad grid and hurricanes like Irma, Ien, and fires, when they cut the power for hrs or days putting the fire down. I have seen a lot of bad installations by “i am electrician, I can do anything”, that ended up having issues, but it was all resolved mostly by the warranty.
Also generac has aluminum body with powder coating. And now we are installing 26kw, which is 109A ish load compare to 83,5A 20kw. 25A more which is significant
I love my 16kw Natural Gas Generac. I have a 10 year warranty already 6 years into ownership. Even when its 20 below zero it starts right up. Even when power goes off and on 20 tines in 2 days...no issues.
Power is clean and I am so confident it keeps my hot tub going as well so it wont freeze.
Now Inget mobillink messages whenever it runs or has an issue.
I have never lost anything that runs on electricity because the power coming from it is that good. I also have a 7kw on grid solar system and this works flawlessly with it.
I am sooo happy with this Generac generator and Generac whole house switch I highly recomend it.
What about sound levels?
That would be a great test and some great data to have in the video. Will let the production team know.
some of the units in this video are water cooled industrial units. Nothing like what is in the two hime use models reviewed .
Which one is less complicated and less maintenance cost?
Thanks 😊
Welcome 😊
As a generator tech who has serviced both Kohler and Generac, Generac is hands down the best unit. Your video was very very inaccurate. G force engines are in air cooled units not the liquid cooled. Most of generac liquid cooled engines are Ford Windsor engines. The generac unit does exercise once a week. You kept also saying they run off gasoline. None of those units run off of gasoline. Either Natural Gas or Liquid Propane. Gasoline is completely different. Generac has an all aluminum body while Kohlers are just a cheap plastic and fiberglass. There is a reason why 80 percent of home standby generators are GENERAC not Kohlers. Buy a generac!!!!!
LOL - Let me guess - you're employed by Generac or sell them, but not Kohler, right? Because you are so out of step with the opposite opinion which is held by the vast majority of your fellow techs.
Changing oil and filters i.e. "servicing" generators is not the same as troubleshooting and repairing. I have "serviced" a dozen different brands, and some are definitely better than others. And while generac has improved some, they still have a ways to go in quality. You harp about the poly enclosure of the Kohler as being cheap, how long would you think a steel/aluminum enclosure would last in a salt air environment? That is to say, you can buy a "poly" enclosure for areas that need it, or an aluminum enclosure if that is your preference. Both are available.
Glad I came to comments
I heard that Generac has piss poor warranty and customer service.
Thanks for sharing.
