After the dealer did a site survey and needs assessment, I scheduled an installation of Model # 70421 to include two transfer switches for my two 200 AMP service panels. The install was done on the day scheduled and as it has only been two days later without a power failure, I cannot comment on its performance. However, the installer did show me how the system takes over from outside electrical providers to power all of my electrical needs for my house. The unit is quiet and blends in with the outside of the house. I did sign up for the maintenance agreement for two years, but a DIY kit is available. In the past outages I have been both cold or hot and worried about food spoilage not knowing when power would be restored. Also, without power, food preparation and watching TV wasn't possible. Three of my neighbors also installed Generac units at the same time.

I have had a long history with Generac emergency power systems from my 40 years as a General Supt of Power Operations in NYC Transit. Our crews started using portable trailer mounted units to supply critical power to train signal circuits and other necessary power needs in our substations. The reliability of these machines made a positive impact on Transit by reducing train delays and ensuring the people of NYC experienced as little delay as possible, in their commuting during local power outages. Knowing this, when I retired and moved to rural Hubertus Wisconsin, Generac was my first and only choice when I decided to have emergency power installed. My new unit is quiet and now, with winter storms looming, I guess it will get a workout when needed. I am talking on Amateur radio each day, and several "hams" have started the process of having Generac systems installed in their homes. One fellow in Connecticut was fed up with the days and yes, weeks, long outages so he purchased his Generac which is to be installed very soon. I guess one can say we are satisfied customers and are thankful for the quality products offered by your company!

First off, let me say the generator and the crew who installed would get 10 stars if possible. Make sure installer has someone to handle all permits and follow through as we had to run on generator all night due to permit not being sent to power company

My Generac was just installed. The installer did a super job. The installation looks great. The visual of the generator is very good and enhances the overall view of my house. When it was turned on, I started every electric appliance in my house and the generator never missed a beat. I went through Harvey with a small portable generator to which I had to add gas and oil every few hours. Now I will be able to run everything and never add fuel because it runs on natural gas. Everything is automatic so I won't have to worry about electricity if I am gone during a storm. Pease of mind is worth a lot.

We had our generator hooked up 2 days before hurricane Irma hit Florida Sept. 2017. We never lost one second of power at our house ,all our family brought there food to put in our freezer,so not only our family was helped out in the storm. We now have 3 other familys that are getting there own Generac. Thank you Generac for having a great product you truly was a comfort to us for 6 long days .

The installation crew from the setup, the gas installers, the electrical installers, and the startup man were absolutely fantastic. The startup man (Greg) had to install a NEW STARTER. If I may suggest, would have more quality control at your manufacturing facility so this does not occur on this part or any other.

After many years of multiple day power outages, i was looking for a highly reliable backup generator. The Generac 22kW generator i recently purchased answers the mail. It is a top quality product, installed by a skilled staff, and has work flawlessly. My neighborhood has lost power twice since my generator was installed and my internet, fridge, heat, and oven's operations have never been compromised. As a "plus", the output power of the generator is so clean, that i need not worry about "dirty" power damaging my electronics. Well done Generac!!

My 22kW Generac generator was installed by the Generac Authorized Dealer that I found on this website in September 2021. On May 5, 2022 the power went out for the first time. In about a minute my generator kicked on and I was reassured about my $18,000 investment for my family's piece of mind. That piece of mind lasted about 2 minutes until the generator suddenly shut down and I got a "E2098 Stopped Alarm wiring Error" and generator required service to correct. Until July 9, 2022, I assumed correcting this error was covered under the touted limited warranty since the unit was only 8 months old at the time...but I just got a bill, from the same Generac Authorized Dealer who installed this, to fix an error after TWO minutes of providing promised protection (thats what prompted me to write this review) Now, after ~10 months in use, and this product failing the only time I depended on it...I question it's ability to provide reliable back up power for any portion of my home. Finally, my generator arrived without the Wi-Fi, thus I can't use the phone app that looked so cool in the commercials. My dealer assured me that once my generator was fully installed and registered, Generac would ship the Wi-Fi to the installation address...10 months later no Wi-Fi, just another broken promise. P.S. I just read the T&C and they can refuse to post any review they want, so really curious if my honest review makes it here.

Samuel and James from Holly Electric did a great job throughout the install process. Explained the operation once it was up and running. Heather did a great job of keeping me updated through the entire process from quote to install. This unit replace an smaller generator that was only able to run a few appliances and lights. Nice to have whole house comfort now. Have a 250 gallon propane tank to ensure we can weather through a hurricane or sever storm.

Hightower Electric was an excellent choice for obtaining our Generac standby automatic generator system. Mike Lowrey explained the correct sizing of the generator needed and dealing with local gas utility. He obtained the permits from the township, kept us informed of schedule progress, performed the work on the agreed date and scheduled the two township inspections required before final acceptance. He offered as an add-on option a replacement of our home's old main electrical panel box with new circuit breakers and proper grounding. There were no surprises, in terms of project scope, schedule and cost.
