Awesome investment. We needed to install a generator for medical usage. When we started caring for my mom she needs oxygen 24/7. The generator was a life saver because since we had it our electricity has went out on several occasions and it switched over quickly with no problems. Thanks Generac.

Bought this generator about 6 weeks ago. The install was completed without any issues or concerns. Final connection was completed after gas company upgraded the meter. We had a power outage about 2 weeks after the install and never noticed the power going out. The generator started so fast there was never a flicker of the lights.

Our most recent purchase was a replacement unit for fhe original used unit we had for 10 years. We did not even hesitate when it came for the replacement. Our first unit was about 5 years old when we got it and it lasted another 10 years and was an absolute blessing when we needed it. So happy we installed a whole home generator shortly after we moved in!

Bought 2 months ago and not satisfied ,Contractor had to Come 4 weeks straight to deal with low fuel pressure fault/shutdown during weekly exercise. Not very confident that generator will work properly during loss of power due to these issues Contractor who installed where outstanding

The Wifi connection had to be replaced with a module that allowed for Ethernet connection cable. All customers I talked to tell me the same issue. The Wi-Fi will not connect and stay connected. When we have had shorter power outages, I would like the generator to wait at least 20-30 minutes before going back to Utility. It has to be much harder on the equipment going on and off too many times an hour. It has operated fine otherwise.

Running now for a year. We have had power outages while away. It was great not worrying about the basement flooding. We have also had a couple long term outages and it's nice not having to pull out our gas one and set it up. We didn't go for the whole home. We have our furnace, well, sump pump, septic, freezer room, kitchen fridge and some outlets. We also have my aquariums running on a circuit. Well worth the money

Again, my problem is with the electric company that installed it rather than the product itself. But unfortunately, I have not had the support that I would have requested. I.e. asking for a quote for the extended warranty never getting one if Generac can offer that to me now I would be receptive.

I was hesitant to purchase this at first. My wife insisted that we do. Since purchase we have had 2 major storms and the Generac has performed flawlessly. The whole valley was without power for 2 days and we were eating popcorn and watching Netflix. I will say that we can hear it running when it comes on, but it's a small price to pay for comfort.

It’s about two years old . I have done the maintenance myself using generic oil and filters spark plugs and air filters no aftermarket products and it ran 8 days and nights this past January during the worst ice storm I have ever been through it ran everything flawlessly

I live north of Buffalo, NY and we get some wild weather. 20+ years ago I had a 13kw partial home Generac generator installed I never had an issue with its operation for 2 decades. Due the age of the 13kw and hours I had on the unit - I added a manual hour meter; it was time for an upgrade. I chose the 18kw whole house with external whole house transfer switch. The dealer arrived with 2 installers and 3 electricians and knocked out the replacement installation in about 6 hours which was remarkably fast. It was also tiptop work and passed the town electrical inspection quickly. The new 18kw whole house Generac is totally next generation with the app connectivity, ease of access for service, upgraded all aluminum cabinet, sloped top to assist snow removal to the front of the machine away from the rear air intake and the included battery and oil filter heater and an AGM (absorbed glass mat) battery, not a standard lead acid battery ensuring top performance in very cold weather. The green status light on the side and even on the air intake is huge improvement as well along with app. The whole house function is worth the investment because I no longer have to guess which circuits are powered. My only concern is that the rear located air intake is a little too low to the ground for my comfort. The rear air intake is only 16 inches off the ground (see photo) and we can get 24 inches of blowing, drifting snow fast. With the low air intake could potentially get blocked with snow. I'm mulling some sort of a DIY snow guard near the air intake on the back of the generator. Perhaps a drift fence on both sides of the generator about 2-3 feet away. I also enabled a 7-year warranty on the new 18kw Generac as part of a promotion, a definite plus. Based on my 20+ years of Generac ownership and after seeing the remarkable upgrades on the 2026 whole home 18kw Generac unit I can enthusiastically endorse Generac automatic standby natural gas generators without hesitation
