The generator is nicely designed and is quiet. Operation is automatic with 7 second delay. With locks to keep the unit access secure and bolted to a concrete base keeps the unit safe and stable. Totally happy with this product and would recommend to anyone looking to install a whole house generator.

We live in a rural Ontario region. Our concern about power stability is well founded as there are outages from time-to-time. We are very relieved to have invested in the 22kw Guardian. We received excellent dealer service and follow up on all of our questions. We have highly recommended Generac products to our friends.

Stuller's process of providing the initial sight analysis, listening to the details of what I wanted updated and changed was very pleasant. They followed up promptly with a comprehensive proposal & estimate with a clear explanation of each system component. This gave me the reassurance they had the experience and expertise I was looking for. In addition, they provided fair pricing and even took the time to correct errors identified in our original generator installation. Their attention to detail and pride they take in their work was impressive! Thank you for a job well done!

We lose electricity quite often do to animals causing transformers to shut down or bad weather conditions. Just two days ago an owl flew into the transformer. We would have been without electricity for nearly two hours, but because of our wonderful generator , that did not happen. We were only out of power for about a minute. That was great.

This generator and transfer switch perform flawlessly. In less than a minute, power is restored to the whole house during a power outage. The WIFI connection is a wonderful feature. The Generac dealer knows if there is problem with the system before I do. The installation went quickly without any hiccups. I could not ask for a more thorough and professional installation. I would recommend this generator package without reservation. Peace of mind, that my family is safe and sound during a power interruption is worth the price.

From start to finish we were treated with care and respect. The Generac Team had a positive "can do" attitude. They answered all our questions thoroughly, making sure we were satisfied with our new generator. I highly recommend them for your back-up generator needs and more. A big thank you to the Generac Team.

Our electrician - a true perfectionist, and among the most honorable men we've ever met - has installed hundreds of whole-house generators, and won't recommend anything other than a Generac. He swears by their reliability, quality electrical components, sturdy and rust-free enclosures, durable engines, and the clean current they provide. During installation, he opened the generator and pointed out all the elements of Generac's thoughtful, maintenance-friendly design. All in all, it's obvious why Generac is the dominant player in whole-house generators.

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.

We LOVE our new whole house generator. I have oxygen machines that require electricity to charge. It gives us peace of mind to have the generator in event of power failure. We have had one power shortage since installation. It came on promptly, powered our house and used very little gas to run for about 4-5 hours. It is great! Also increases the value of our home. Love it and am so glad we purchased!

I was very excited to finally get my new Generac installed. We live on the gulf coast and flooded in Harvey. We've had power surges and other electrical issues and anytime in a Texas summer without A/C wasn't feasible. We've got a really nice Wi-Fi 6 Mesh system installed in the house with plenty of range all around our property. There is no place in the house or yard where we get a poor Wi-Fi signal. The Generac 26kW uses only the 2.4GHz band, which isn't a problem, because I can create a dedicated SSID that is 2.4 GHz only, which I did. The problem is the range. Our mesh routers do not send out that dedicated SSID, only the main main router connected to the modem. Even though the generator would recognize the SSID, the signal wasn't reliable enough to maintain a connection. I had to order a $20 Wi-Fi range extender and plug it into the wall adjacent to the generator to get a strong-enough signal to maintain connection. Even now the signal strength is only 52-56%. Just go ahead and spend the money on a check TP-Link range extender and set it up on a 2.4GHz band for your generator. IT will save you a lot of trouble.
