Simple user friendly.

Peace of mind is everything after a crisis. From beginning to end the transition and process of quoting to installation was seamless. Very very happy with the product.

Power Saver

My second Generac at 2 different houses and it is comforting knowing if my power goes out I have a power source to power my home. Installation was easy and sales assistant was indeed very helpful. Try it and you will be happy.

Reliable, well made, warranty and service ..

We had a Generac standby generator at our previous home. It proved itself during two major ice storms and a hurricane. When we moved, we again selected Generac for our standby generator.

Eases power outage PTSD.

Haven't lost house power since the Generac was installed so don't have any actual use data as yet. Weekly test firings have occurred and seem normal.

Peace of mind

The unit works very well, and it has provided service several times when the electric grid failed. It provides us with a great feeling of safety and peace of mind.

Easy to use

Great company for install from start to finish. Works great. Hope it is never needed. All team members were polite and organized. Always showed when they were supposed to.

An absolute dream

We live in a very wooded suburb of Boston. One might think that living 30 minutes outside of a city isn't the type of place for power issues, but our town is densely wooded with lots of tall mature pines everywhere. Whenever there's any kind of storm, be it a thunderstorm in the summer, a nor'easter or ice storm in the winter, we lose power almost guaranteed. The power company in our area is also extremely slow to restore power. Any outage guarantees at least 12+ hours of downtime, with many outages lasting 2-3 days. We got tired of spoiled food, no heat, and just huge headaches. We got this 18kW Generac 7226 installed by a local dealer last year, and it's already gotten us through two multi-day outages. It's so nice to not worry about our refrigerator and our heat in the wintertime anymore. We're able to continue our daily lives as normal while it just hums away outside powering our house. The automatic transfer switch takes care of switching back to main power after immediately once it's back, even in the middle of the night. If you're on the fence, go for a Generac. You won't be disappointed.

Good Machine but With Issue

Just over a week or so ago I purchased a new 14 kw standby generator, and had it installed by Pine Tree Standby Power - They were excellent from start to finish - Generator wise, it seems to run well after test trials and has exercised twice since install - My heartburn comes from this - One of the advertised features of this unit is the ability to remotely monitor it via its onboard Wi-Fi module and a downloaded app on your smart phone - This was important to me as I am handicap and it is hard for me to get to the generator - A great feature if it actually worked - I must preface comments by saying I am retired from a 40 year career in network engineering so I know just a little - After hours of attempts to setup the generator Wi-Fi, all failures, I concluded that the unit was not communicating with the network - The unit is no more than 15 feet from the router, and yes I was sending 2.4Ghz signal to it. I began research only to find that this is a VERY common issue for this unit - I called support and got a gent who was very polite but lackluster - After making me walk through EVERYTHING I had already done (and told him so) he concluded the generator was not communicating with the network and wasn't going to it seemed - His suggestion was that I look into a Wi-Fi extender to increase signal or get a different Generac Wi-Fi module - After research, I learned that Generac has known about the weak Wi-Fi module issues yet let them exist and still keeps plugging the feature in ads and flyers - Yes I could buy a network extender. Yes I could order the replacement Generac Wi-Fi module from their website at a cost of over over $300 - BUT why should I have to pay to make the 14,000 dollar investment run as advertised? Any distance over 20 feet from the router and the supplied module will not get/hold connection - If you are thinking of this unit for the remote monitoring look elsewhere - As the unit is only two weeks old I am seriously thinking of calling the dealer to refund me, take it lout, and then get a more reliable one

New generac blew oil and then just quit

We paid over 10 grand just a year ago for brand new generac. It's only ran for 5 minutes at a time for its weekly test. We lost power 4 days a go. The generac kicked on and has ran solid. We haven't used much power. Mostly lights and fridge. This morning, the generac just quit. Went to check it out and it has blown oil out the side. They say our power is still a day, possibly from returning. Called generac and they can't get anyone here for at least 3 days. I'm very disappointed and sickened that we spent well over 10 grand on this product. I don't feel at all comforted ,now, for having it for emergency.
