Generac Power Systems Reviews

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.

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.

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.

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.
