Love our Generac❤️

We have been thinking about buying a Generac for years. So glad we finally did! Our neighbors had their installation done in 2018. Every time a storm caused an outage, they were completely comfortable, up and running! It has made us feel much more secure with the hurricane season coming.

Perfect for what we need.

Purchased a year and a half ago. Have had it kick in and run twice for about half a day each. As well as test running it has been very reliable! My wife and I are getting on in years and I have developed major health issues. Last major power outage was during Fiona and I was without electricity for a month. We have many medical items to assist us and are crucial. Was running for gas every day and waiting in line like everyone else, as well as trying to find open streets while the power crews tried to restore power. So finally said that this is enough and we are going to get a full house power unit and enough propane fuel to last a month. Feel the power situation isn’t going to get any better soon.

So Relieved and Happy

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

Has Never Worked - multiple faults and service

Installed two months - 1 power outage - unit failed. dealer has been out 8-10x. new motor, new wiring harness. every sensor has displayed multiple faults. total piece of junk. I have had a green mobile link status 2 days out of 2 months. At this point Generac should be refunding me my money and removing this unit! it has never worked. think there are serious electrical / computer issues with this brand. all my neighbors that have generac told me it took several months to get them sorted.

26 kW backup generator

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.

Must Have for East Coast living!

I moved to PA from CA 2 years ago and when I was doing my walk through on my new house my neighbor said that I should get a generator, the power goes out often in this area. A few months later the power went out a tree took down the power line at the end of the block. The power was out for 2 days. I ordered my Generac Generator immediately! All the homes on the block had their generators running and the lights were on. My wife and I sat on the front porch in the dark and watched the moon. Ha Ha. We have had 2 power outages since I have had the unit and it is such a great feeling to know that you don't have to sit in the dark. Well worth the investment. I did a lot of research and Generac seems to be the best system out there for homeowners.

We love our Generac!

We had our Generac installed during the winter. The process was handled with care and patience. We have family and friends with Generac home generators and we heard nothing but good things about them. The generator is turned on remotely once a week to make sure everything works properly. It’s so good to hear it running and to know it’s ready at a moments notice.

Just do it

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.

Great longevity, NO issues for 20+ years

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
