  My generator is 3 years old and I have had trouble wuth my Generac since installation . When I lose power and it's raining outside, my generator may run 30 to 35 minutes and then quits. I am so sorry that I bought a Generac and feel like the unit should have been replaced from the beginning. I am a widow and struggled to purchase this unit to help me out during power outages. The Joke is on me.

  My generac had an oil leak, blown fuse, and bad spark plugs upon first install. I got the spark plugs and fuse changed. When me and the installation company called generac to talk about warranty ; the lady for generac told us she was going on vacation so she could not help us. Now been 6 weeks with a generator just rotting in my yard. Should have bought a kohler

  I live in ************* and I bought a 24KW Generac Generator. $14,000 (Generator plus installation) I bought the generator right before Beryl (Hurricane) devastated the area. I was so relieved to have it, because I lost all my food and had to stay at an expensive hotel when we were hit with the tornado. (The price gouging was real) Wouldn’t you guess the brand new Generac does not work. I asked for a new one and I was told that I registered the Generator to my name and address. The crazy thing is you have to register it before you can start it to see if it works, so it’s like a trap of sorts. So you would think they would come and repair it with a sense of urgency……… nope I’m being told they can’t come until September 2024. Apparently there are so many families who own Generac’s that didn’t work that the Generac Technicians are booked out for 2 to 3 months. Keep in mind we are in the middle of hurricane season and it don’t end until November! When I tell you I regret buying a Generac and not looking into alternatives. Buyers Remorse is a real thing. But I’m gonna call the ***** Attorney General consumer affairs, and look for an attorney. Based on all the reviews I have read on this site ***** has a problem with Generac!!!

  My generator is 2.5 years old. During hurricane ***** my generator died. Im an 83 year old widow who purchased this for safety of my well being. It has failed. Im so disappointed in the service I have received. I have called 13 times and sent in 2 request and I have yet to hear from anyone. This is uncalled for and unprofessional. A receptionist has put me on the emergency list twice and still no response. I feel like Generator Supercenter does not care about their customers. I dont want an apology I want my generator repaired.

  GENERAC failed us when we needed them most.Bought a 22 kw generator 4 years ago and have always done service on this unit, 3 hours into Hurricane ***** it stopped producing, I received error code 1902, tech came out and said it was a known defect, rotor issue and it would be 6 weeks before the parts would arrive, I didnt have any other backup, as I should have been able to depend on this unit to protect our home during these power outages.2 freezers and refrigerators full of food lost, had to spend thousands of dollars on hotels if you could find one.Very disappointed with Generac as it let us down.Now my concern is will it fail again after repair We bought this unit from GENERAC Super Center in ******* *****

  I am a Generac generator owner, it is at my residence. I live in ******, **. I am very disappointed with my purchase. We had a storm come through in May 2024 and our power went out and our generator would turn on and then turn off. We could not get it to stay on and power the house. Mind you, we have a service agreement so it is monitored and maintenance regularly. My husband also checks the oil every 12 hours when it is running even though it is recommended to do it every 24 hours. He checks it more frequently just to be safe. So we called the 1-800 number and they eventually sent out a technician to look at it. The technician told us it was a part called a brush or brushing and that it needed to be replaced. He replaced it and it worked fine. Fast forward to Hurricane Beryl, our power went out Monday, July 8 at about 6 am and the generator kicks in and powers the house. Great news, right? WRONG! Today, July 12 at around 4:30 am the generator stopped working again. It is giving us the same error code as last time so it appears to be the same part out again. A technician arrived at our residence July 15 (Monday) afternoon to do diagnostics on our unit. His evaluation was exactly what I thought it would be. It is the exact same part (a brush) that went out in May 2024 and of course he does not have the part in stock. The technician (Lane) said that he will have to order the part and it will take approximately three weeks to arrive. The technician also said that our generator is from the ***** ******** factory and that he is being told that the rotor in units from that factory were not calibrated correctly. He also told us that Generac is aware of the problem and at this time they are not doing anything to correct it. That is unacceptable. I paid a ton of money for this and you have sold me a lemon. How is replacing the part going to permanently fix it? It's not, it is just a band-aid until the part fails again. DO NOT BUY A GENERAC!

  Engine took terminal dump 12 hours before Hurricane ***** hit with only 3 hours running time on it. Was out of warranty from a calendar standpoint, but 3 hours? Really?! They basically said to F.O.A.D. And I had bought (2) 17500E's at $3000+ each +$1000+ electrical work. They also never even called. 4 different people sent 3 sentence emails saying too bad-so sad. I cannot say enough derogatory things about this company. They ****! Goodbye Generac, ***********

  I have a Generac hole house generator two and a half years old with 22hrs on it. The first time we ever needed it, it ran for 1/2 hour then quit, I contacted a certified Generac technician to repair it. When he turned in the warranty claim Generac denied the claim due to moving it to our new home by a certified Generac electrician. The electrician told me he never heard of that in all the years he's been installing them. We needed a new rotor and brush set $1250.00 We need help with this.

  I purchased the generac generator from ******, in ************ last year. I never thought buying this brand I heard badly review more than good. While I do my own investigation on product I decided to but this for our home usage. Well, I tried to always be very fair and trustworthy to best of all information provided with proof. I've only used this product twice one during a Texas Tornado on May 2024, and now the Hurricane Berrel July 7th, 2024. And let me say I'm not very thrilled with this product. The first one cost me $308 because the O2 sensor was messed up and it was causing it to die while trying to start. So they fixed it now in this hurricane I can't even use it. I had to send my boy to my mother lost home so he doesn't get sick being he has asthma attack. The heat is so strong in our home because we're out of lights. I already lost my food several months ago and generac wouldn't even have the dignity or the courteous to refund me when I share my situation with them the first time and here's the case# *******. Now I call for second situation. Don't understand after speaking to the technician support saids maybe need repair again on another issue being the breaker on generator keeps flipping. This means again will have spoiled food, had to send my son elsewhere for his comfort, and not able to have no power to refrigerator. My phone can be powered and I have to go to work which is ridiculous because I can't even charge it. The support people that I spoke to today they gave me this new case number# ******* and can't even call me back. Is this not a joke for a great company that says they're so good for the homes. Now? Here's I handle disaster for a living. I have a lot of people that I assisted and I'm going to let them know never to purchase a generac. And for anyone to get back at you that's not so easy. They take forever. Me and my wife are burning up and I have to deal with this BS. I believe that I should get a refund. $1,025.

  Just had a whole house generator installed 5 months ago. Massive storms came through our area a couple days ago and the first time generator had a chance to do its job, it epically fails; after 20 minutes. Was told I need a new motor ... on a brand new unit???? Customer service response was "sorry, these things happen." I don't see that disclosure anywhere on your marketing materials telling people you can feel safe and secure with a Generac. UNBELIEVABLE. Save your money; don't buy one.
