Generac Power Systems Reviews

I question the low scores for Generac. Our experiences have been exceptional, both with the generator and the generator support team that’s available 24-7. The system is a little techy for me and being able to call them and have a person be patient, knowledgeable and clear to understand to assist is well worth the peace of mind this purchase has provided. On a 1-5 scale, I give them 100!

I bought a new gp9200e. Ran it a few times here and there to make sure it was ready for use. Well time finally came and it's a complete turd. It can't run half what my onan pro6000e did. One 240 leg was gone. After about 6-7 hours the missing leg started working, but not enough to power any 220v devices. It runs poorly, governor bounces constantly, power is inconsistent. If you tighten the fuel cap it draws vacuum and starves itself of fuel after an hour, so the cap must remain loose. It's the most awful piece of junk. My onan was trouble free for over a decade. I hoped this would be an upgrade, but it's nothing but a disappointment. I was going to try and fix it, but it's not worth my time. I could never depend on it. This was my first and last experience with a Generac product. Absolute junk.

Size your generator using a good electrician. Total electric homes may require a larger unit. A 22kw unit w/ tax $7k-7.5k. Insure you can get propane co. To set and fill minimum 500gal tank. Some will not do this if you have no other gas appliances. 500 gal tank and first set and fill around $1,000. Plumber needs to install flex connector and hard black pipe to generator with connection for gas regulator at a minimum of 5' from unit. You will need a $250 battery for the generator also. Plumber may cost $150-$300. Natural gas if available is best option. To insure warranty is valid, have a qualified Generac tech perform the initial startup of your unit. I purchased a 22kw unit with transfer switch and flex connector included. Propane company said I was the last customer they would set, fill and service because I'm total electric and the revenue off of my usage is not very much.

Generac Generator purchased in May of 2021. Serial number: 000000003008290317 Unit Description: 48KW 4.5L 120/240 1P NG AL In the 4+ years we have had this generator, it has NEVER worked. It has NEVER once come on when we have lost power. It has an error of "low coolant." When a technician comes to service, they find that there is NOT low coolant. Generac has replaced the sensor twice. This has not worked.

Lost a sale due to shipment being lost. I contacted them for a refund and they refused. 60 days from original order. Was told there is a no return policy. Out of our control and they were unwilling to help. Told us to sell to another customer. Will not recommend to any other dealer.

I'm telling you the worst company to deal with. The second generator I had installed for over $12000 only worked for a month. Also, they forgot to plug my freezers in, and I had over $400 where the food go bad, they can care less. They're trying to get more money out of me for additional parts that wasn't in the estimate nor demon quoted to me. The first generator I had installed on Lasted, 5 years in. They stood toes from my basement.

I am not happy with Generac Generator's customer service. I had a generator installed Sept 2025 and in less than 30 days Oct 2025 a promotion came out for a 10 year warranty and Generac would NOT give me the better warranty, as a courtesy. WHY NOT??? I'm a Veteran, always hearing "Thank you for your service" well it sure would have been nice to be shown some thanks! It is not an unreasonable request to receive the better warranty especially since I just got my unit installed. If it was a product that could have been returned and repurchased I definitely would have done that, to get the better warranty. The general manager for Generac SHOULD NOT BE PROUD of the customer service rendered to me. I wish I could have spoken to the general manager about this. Absolutely ridiculous not to change my warranty after such a short period of time, and Really Thank a Veteran!!!

I had a 22kw whole house Generac generator installed Oct/2018. I have 77 hours of use and the engine has blown. I've maintained it yearly as required. The warranty was up Oct/2023 so I'm screwed. Thanks Generac for your POS. Buyer beware,.

Can’t recommend. The 26k generator was installed by a professional company that does HVAC and generators. After the install they told us all the common failures, that wasn’t great. They also told us, “Don’t waste my time with the app. It’s garbage.” The tech said “even Generac tells us don’t use the app.” Well I installed the app anyway and the wifi signal is horribly weak. I installed a $400 outside WiFi extender less than 10 feet from the generator, which brought my signal to a strength of 50% some days, wow; in all fairness the app did tell me the battery was not charging which there was no way of knowing otherwise. After a service call we found out the technician didn’t hook the wires correct at the transfer switch and blamed it on Generac for changing the wiring recently.

I have a 22kw generator, the rotor and stator failed. it was less than three months out of warranty. Low hours on it. Generac would not cover any of the cost for repair. Looks like Generac has the five-year warranty figured out correctly, so the customer has to pay the bill. If you are thinking about Generac, you better take the extended warranty.

Dealers everywhere, none are trained. Delay 1: Doesn't come with battery. Delay 2: gas line not purged. Delay 3: couldn't operate or test without code. Delay 4: no code issued without serial number. Delay 5: dealer didn't have serial number. 100 miles to unit. Delay 6: customer service woke ** and wouldn't guide or help. Just told me no serial # no help. Told me not to call back and Hung up. Beware. These are monopoly attitudes with zero fs given for customers on 10k product.

We purchased a $15,000 Generac backup generator for our home using a contractor from Generac website. Two years later, the generator stopped working so we proceeded to activate the extended warranty that we purchased. The contractor from their website went out of business and could not provide any maintenance records so they denied our claim. Very disappointing since we purchased the extended warranty.

Take this information a 40 year electrical engineer who has repaired Generac machines and have found them to be JUNK! Unreliable, to not meet their own specs and provide no support (parts, schematics or any support) on their machines over 10 years old from manufacturing date. All Generac techs will charge outrageous prices to service or repair so be aware before spending huge money on the garbage machines. I’ve sold, repaired and installed Gens for over 40 years and you can save yourself thousands of dollars by purchasing a top quality machine.

New residential generator in Dec 2024, spent months trying to connect wifi to mobile app with numerous |Generac tech service agents. New generator had old technology 2.4G wifi module. Generac offered to sell me a new generation wifi module ~$250 for my new generator (ugh). Turns out after a service tech visit that the wifi module and wifi ID label were mismatched at the factory! No amount of attempts by me would have fixed the issue, had I purchased the new wifi module their manufacturing defect would have been concealed. There is obviously another customer with the same issue somewhere. Poorest level of Customer satisfaction I have ever encountered. No commitment to Customer satisfaction or ownership of manufacturing defects! Buy another brand!

At first I was very happy and excited about my new generator! The installation staff was very helpful and professional! But as a new client, I had to deal with some « situation « that needed to be explained! I called the head office in Ontario! The guy (owner) said he’d send a technician! Not only he didn’t, but he got upset when I called him back the day after!! He said he’d send wouldn’t send me a technician each time there is a power outage!! He was very impatient!! I had to call the sales man whom I dealt with, and he said he’d send wouldn’t would send someone to look at the situation, but 2 days later, no one has showed up yet!! Maybe it’s too soon for me to review this service, but I am definitely not impressed by the way things have been handled yet!!!

Worst company ever, I spent over 80K cash in Pwrcell equipment with standby generator in Dec of 2022. Still does not work in 2025, never has worked and they just keep sending people out here to do nothing. I was part of the BETA test program and assured by Generac I would be upgraded if anything needs it to ensure the system would work. I live in SW FL and so far during every power outage, this thing just fails and the inverter trips and fails. Major run around, never buy this Pwrcell junk, just get a regular generator and skip the green energy nonsense. Try Briggs and Stratton, better equipment and better warranty.

I have had a simple issue with my 7500exl Generac portable. I have been working to have customer service help direct me to a engineer or technical person to help with my issue. The idle control coil lock nut came loose which vibration caused the screw to push the speed arm causing the engine to rev high & causing the motor to blow out the circuit board. Getting it back running was what I have done but can't find adjustment for that coil arm. I have been trying since Feb 2025, messaging customer service, hoping someone will help with my simple fix. Needless to say you never get the same person to help on my ticket. Every message sent comes back with a new representative giving some worthless information that I've already know about or tried. Again and again sending multiple messages with the same circle back with worthless information like they don't read any information before the last one pertaining to the ticket.

We purchased our 24k Generac a little over a year ago. So our generator is a little over a year old. It worked fine until we had a complete power outage a few months back. The generator fired up and we had power to all appliances except our A/C. This brings me to when we first had the little guy come to our home to go over the size needed and what we wanted powered during an outage. Our major concern was having A/C during any power outage because we live in the heart of Louisiana where the temperatures are always extremely humid. The generator suggested to us by the salesman was our 24k Generac. We questioned him extensively about this generator powering our A/C and he lied and said this generator is what we wanted. There was no mention of added devices such as their (SMM) smart management module.

Never purchase a Generac generator. They have zero oversight and will allow their dealers to steal your deposit. I hired ACH electric out of Lambertville NJ to do my job. Gave him 9k in December of 23. Kept calling every two weeks. Told I’m next in line. Family had a life changing event in March of 2024. Called to cancel job which he had dragged out. Said it would be a few weeks to get me my money back. No harm no foul. Next customer gets the generator. Reach out several more times till he tells me there is a no refund policy. He screwed me out of 9k. Reach out to generac to complain and they tell me it’s out their hands. So generac is ok with their dealers sticking customers for deposits. I’m thinking about suing federal and ACH Electric. Don't buy Generac products.

The best purchase we ever made. We were contacted immediately and service was top quality. We have had numerous power outages and Generac has always come through for us!!! Would recommend this system to anyone.

Installed in 2013. Maintenance of $160 per year. Used for a total of 130 hours since then. This includes recently, when my local utility went down for 3+ days in the heat. The unit ran fine for 15 hours, then quit. I got an emergency repair ($1000+) and it ran another 15 hours and quit. Now it needs about a $1200 repair of the generator system. So there you have it, 130 hours and the electrical l system is worn out. It is useful for some short term convenience, but never again will my family have security in owning a Generac.

Bought a power washer in 2019. Just it's been ran 1 time. Had to replace battery 3 times. Wouldn't recommend it to anyone. They do absolutely nothing to help you. Basically it's junk and Generac keep giving me runaround. Zero help. Wouldn't recommend to anyone.

New generator install by FA Electric. Dropped off and pad mounted one day, installed in one full day after propane hooked up. Competitive pricing. Very knowledgeable and detail-oriented during estimate and install. Checked heat pump specs to make sure generator model was adequate. Inside panel work, transfer box, and load sheds very neat and orderly. Highly recommend.

I have purchased and installed 3 whole house generators in 3 houses. 2 Kohlers and 1 Generac. The Kohlers were very reliable and service was excellent. The Generac is at best mediocre in reliability and local service is terrible. I called for warranty repair. The service tech came to the house, declared nothing wrong and left then they sent me a bill for $200. 2 weeks later the engine failed in the same way. I called and they said they would not fix it unless I agreed to pay for it because I installed the gas regulator too close to the engine. In reviewing the installation guidelines, there is no spec on that. Do not buy Generac!

Had Triple Tech in Midland Ontario install our Generac system and couldn’t be happier. Sal and his crew did a great job from start to finish. They explained all my responsibilities and schedule for preventative maintenance. Highly recommend Triple Tech

We have purchase a whole house system because we are on oxygen and have b-paps and c-paps for sleeping. We have had it installed for over 4 years and it never has come on in emergency. It tests fine once a week. I have now felt this is one of the worst investments ever and would never do this again. We have had service, but they have yet to find a solution. They are just waiting for the warranty to run out. This is not and reputable American company. Their claims are false and need to be removed from service. Some clients need this protection to work for health reasons.

This is my 4th Generac generator I have had installed by various Generac authorized dealers. All of the installers have been knowledgeable and professional. My latest purchase showed how horrible Generac support for their dealers and customers really is. Once installed and start up took place within 3 minutes there were horrible noises coming from it and my technician shut it down immediately. After a tear down by my installer to find out the cause it became apparent that the generator had been assembled incorrectly in the magneto area. Once new parts arrived and installed it also became apparent that there was more damage done by the start up in the flywheel area.

We had an authorized dealer install a Generac Solar System complete with a backup storage system less than two years ago. It has the attached remote viewing system so that Generac can check on it at any time. We built the new heated shed to house the battery backup. The installation company has gone out of business. The backup system went down last November. We have made numerous calls and emails to Generac customer service. They say they have not been able to locate any service personnel to work on it. I called the nearest company I could find which services Generac, but they don't do warranty work. We are making payments higher than any benefit we have received from the solar panel working alone without the backup system. Our Generac system has been nothing but a money pit to us.

When you purchase your Generac generator, that is just the beginning of your costs. Then it suggested you buy a maintenance contract which will cost at least $395 per year. Otherwise all warranty calls come with a diagnostic fee to get someone out to check/fix the problem. The Generators come Wi-Fi equipped, but the free Wi-Fi app from Generac does very little except receiving countless push notifications. [You can’t even crank the generator using the “free” app]. You’re invited to upgrade the app for another fee per year to make your Wi-Fi fully functional.

I have a Generac micro inverter system. My installer replaced a unit under warranty. When he contacted support to have it provisioned, they may have provisioned it incorrectly, two days later the unit was no longer showing any voltage. He opened a support ticket but no one from Generac would reply. To help get support I called the number on the case. After being transferred a few times I was unable to to get support. I asked them to formally escalate the lack of support but they refused. Despite a warranty replacement of a Generac micro inverter unit and subsequent failure, I have received no support from Generac. The installer believes the replacement unit was incorrectly provisioned, leading to a zero-voltage state. Both the installer's support ticket and my direct calls have been ignored. Generac has also refused my request for formal escalation of this issue. Terrible after sales support!

I purchased a new Generac generator and had it installed by a local contractor. The install was great and it was complete in October of 2024. My first need for the generator was in January of 2025 and if failed to start. I was told it was a bad ignition coil. That was three weeks ago and I am still waiting on a part that I was told was in stock.

Do not buy Generac generators. Purchased a 24KW unit in January 2025 at a cost of $12K including installation. Lost power on February 12, 2025 for the first time. The generator ran for five hours and shut down due to low oil pressure. There was a puddle of oil underneath the motor. Contacted Generac service. No feedback when they will schedule a service call.

Our Generac Home Generator is 3 years old. I purchased the generator with a 7-year warranty. Two weeks ago, I noticed that the indicator light was red, so I called the dealer (after 5 PM on Friday), got a recording, and left a message to call me on Monday. I waited until noon and no call. I called the dealer, and they said that they would have a technician out the next day. The tech arrived and diagnosed the problem and was gone in less than 30 minutes.

We have a whole house system. 3 service calls under a year. First was electrical wiring, second and third was under power error. Now they want me to purchase a block heater because the cold weather caused a non start. Only problem is we had the same issue during warm weather. When you invest that amount of money you expect to have quality parts and service.

We bought a Generac generator for our home, expecting it to work during emergencies. However, during the hurricane in July 2024, the generator failed to start, even though we had it serviced and were told it would work while we were away. When we returned a week later, our house smelled awful, and we lost hundreds of dollars worth of food. It’s now January 2025, and we still haven’t been able to get anyone from Generac to help us. We’ve tried calling and emailing multiple times, but all we get are automated responses. Their customer service is terrible, and we’re extremely disappointed. I wouldn’t recommend Generac to anyone.

Stay away! They took my $13,000 3 months ago and cannot tell me when I could get a generator. Even worse the dealer has no knowledge, so they grab your cash and tell Canadians to sit on it! Customer service writes to you with a code to simply say we have no clue where you are in the cue and when you could expect a unit. Is this 2025? Got to think you can track orders? Horrible experience

My generator has malfunctioned since day one. Every time I call to have someone come repair it, the appointment is over a month away. The help line is very unhelpful. The nearest dealer is over an hour away, and they usually "can't find the problem" till the second or third visit.

Go with Generac Generators via Canteer Power if you live in SC (over 70 years in business) for your generator needs. They only specialize in Generac and you don't have to wait. The came in over $1K less and didn't have to go through the attic, etc. Finance interest free via H Depot like I did. 24/7 remote monitoring, 10 year warranty. Don't be without power. Generac, only the best.

The motor stopped working correctly on our 14KW Generac Generator. Fortunately, it was covered under warranty. MS Solar ordered the replacement motor at the end of Oct 2024. At the end of Dec 2024, we still had no probable delivery date on the motor. I had to repeatedly call MS Solar during Nov and Dec to inquire as to the status of the replacement motor. They did no follow-up on their own--my inquiries triggered their follow-up. Frustrated at going two months with no generator, I asked the owner to call me. He/she did not. Instead, I received a text message from their staff, reconfirming that they had ordered the part in late Oct. I finally bypassed MS Solar and called Generac directly. They provided me with a shipping date. Does it REALLY take two months for Generac to fulfill its warranty promises? This is NOT the service we paid for.

My XT8000E starts usually very good but I use non ethanol gas and a fuel stabilizer. The hour meter failed though at around 23 hours I believe and had to buy another and found they are rather high priced. For some reason, it wasn't designed to charge the battery when running which is a flaw. If you read the manual, you will find the valve clearance is supposed to be adjusted at 50 hours. If you want to do the valve adjustment yourself, it’s best to get a service manual. It can be challenging to get a service manual though from a dealer I found but a digital pdf version doesn't cost anything.
