    I do not recommend Generac! I purchased a unit for my egg room, and since the date of installation the unit has not stored one time. A call was made to Generac to assist in a failed new unit and they just played the blame game and said it was the gas hook up problem. So I called and had to pay another gas man again to check and it was hooked up correctly and set at manufacture specs and the unit will not start. They sent a Generac service man out after three months and he determined it had a bad motor and would get it taken care of within ten days and it’s been a month now and he will lot answer phone or text and no communication.

    The local guy who sold the machine sticking his neck out for Generac had to the pay the service guy 250$ dollars for a faulty warranty issue. I called Generac and they told me to call the service and again gave me the same guys number this has failed me already and said that’s all. They could do. Save yourself a lot of headache and just go with another brand but check to make sure they have good reviews. DONT BUY GENERAC.

    When hurricane Helene hit us here in Dearing Georgia, daily for three weeks I had to find gas stations for fuel and daily I had to carry thirteen gallons of fuel to feed my two 8500 watt generators to supply power to my home. I’m 64 years old so with that I had had enough. I called Generac and a service man came out and said due to demand it would be about three months before an install could be done. I gave him a $6000.00 deposit and two months later they were here ahead of schedule, I’m a retired electrical engineer so as they performing their job I allowed them their space to do their jobs.

    Install took about three hours and my gas company was here as well to fuel my new generator. The electric company was out of Waynesboro Georgia, they were clean and left no mess to clean up and at that point I wrote them a check for the second payment of $6100.00 for a total of $12,100.00 and here’s the best part, since the install after hurricane Helene my home has lost power twice and within seconds my Generac was up and running powering my whole home.

    I have it set to power on every Saturday at noon to cycle for five minutes and it does so very well. I’ve read the complaints and I’m very sorry for those individuals but let me add this, it has to be your installers who are failing you because I cannot be more happy with my system. If I ever sell my home my next home will be secured by Generac. One final note, I paid $12,100.00 for my Generac and it raised the value of my home by $20,000.00. M. ** Dearing Georgia

      I have no complaints about the portable generator I purchased. So far so good. However, I have never had such poor customer service from a company. I have contacted customer service twice now, and both times I have spoken to an elderly females that just act irritated and rude.

      I am an electrical contractor with a Generac Installers certification. I would not advise buying a Generac generator. They are unreliable. They have an issue out of the box 80% of the time. They just "upgraded" the installation to be 100% via app and it fails to install correctly 100% of the time. Pick any other brand.

      Generac warranty is very close to being worthless. I had my generac professionally installed and just a few months later, it was not working properly as it would quit running and show error codes. I called generac and they gave me the contact for an authorized generac maintenance company. The technician came out and found that the ground wires to the circuit board were loose from factory. I spent months trying to get reimbursed for the money that I paid for the service call and finally got only about a third of what I paid. Generac SUCKS! I would not recommend them. They are crooks! I wish I had never bought a generac. BUYER BEWARE, THEY WILL NOT STAND BEHIND THEIR WARRANTY. JUST ANOTHER RIP-OFF COMPANY!

      I spend 5k a year for repair and maintenance on a 120v and a 480v generator. Both with the Ford engine and natural gas. We haven't lost power twice in the past 3 years. I pay for the yearly maintenance contract and it always costs A LOT more to find the issues and repair them. The last maintenance visit, I have had the repair guys out at least every month as they keep failing to start on the weekly maintenance start up.

      Bought full house generator in September 2025. Electric went out in January 2026, generator ran for 26 hours. Then the engine died. Took over 3 weeks for new engine to arrive. February 2026 new engine installed. March 2026 it ran for 4 hours and died. Here it is 3 weeks later still waiting for Generac grievances and appeals to let me know what they are going to do. I told them this unit is a lemon and I want a complete new one and for them to add a 10 year warranty.

      My husband prefers that they would give us our money (over $13k) back and take their lemon back… In his opinion what good is a warranty if it’s always broke and takes weeks to repair. I still have PTSD from Helene and so wanted peace of mind. We’ve had 2 electric outages while this generator is down… There is nothing worse than spent a huge amount of money and having a useless hulk in your yard. Do not buy from this company. I’m writing the state attorney general’s office and see how many letters they’ve received with stories like mine.

      We own a 24kw Generac generator with three smart switches. The unit is a little over five years old. We have had to replace all three smart switches as all of them have failed. Generac admitted they were a weak component yet refused to help in any way. The customer service rep only stated that the warranty on the replacement switches is now three years where they used to be covered only for one year. Obviously, these switches are a problem and Generac has no intention of helping. Truly poor customer service and poor dependability of a component that should last much longer. You may want to look for other alternatives for standby power.

      Had my Generac 9 years and the engine died 1/30/2026. It is under warranty and still haven’t had it replaced. Generac Customer Service is awful and I would not recommend them to anyone looking for a full house generator. Use anyone but Generac. Awful!!!

      I purchased the Generac based on good reports. In terms of reliability. However, within I warranty period my motor was defective and was replaced. Unfortunately within 3 years of it being replaced the new motor seized And Generac did not offer any type of warranty on the new motor defect. I contacted generac head office hoping to work out some type of a warranty agreement. But with no luck. If you're going to provide a customer with a new motor that motor should not seize within a couple of years with no recourse to the homeowner.

      Generac Power Systems author review by ConsumerAffairs Research Team

      For over 50 years, Generac has been making residential standby generators. Today it also makes portable and industrial generators, fully automatic transfer switches and accessories for backup power applications. Consumers can choose from multiple fuel types for their generators and many different series and models based on their specific needs.

      • Generators for homeowners: Generac makes over 40 models of residential generators across six series: The Guardian, Synergy, EcoGen, PowerPact, QuietSource and Protector series. Each model in the homeowner generator category runs on natural gas or liquid propane and sits outside like a typical air conditioning unit. Each model delivers backup power directly to your home’s electrical panel, eliminating the need for extension cords, and runs on your existing natural gas or liquid propane fuel supply so you won’t run out of fuel.

      • Generators for business: Generac offers businesses with multiple standby power solutions including gas- and diesel-fueled, bi-fuel and modular power systems. Its single generators offer up to two megawatts of power, while its paralleling systems allow for multiple units to be installed together, offering standby power of up to 7,000 watts.

      • Mobile generators: Generac’s line of mobile generators can be fueled by diesel or gas, have a rugged, durable design and come with wheels for easy transportation across multiple types of terrain. Mobile units include generators, light towers, heaters, pumps, water trailers and government/military-used generators, which are customized for remote military locations.

      • Mobile remote monitoring: Generac’s residential generators come with Mobile Link remote monitoring. This feature allows you to check your generator's status from your laptop, tablet or smartphone.

      • Pricing: Generac has a tool on its website to help you locate the nearest dealer to your location. A dealer's website site generally lists pricing for the models they carry, or you can call for pricing.
