Purchased 22KW Unit in Jul 2016. Installation instruction were excellent. The unit has furnished power during two outages since installed and operated flawlessly. I would recommend this unit to anyone who, like me, lives in a rural area where frequent loss of power is likely. CLM, Vanceboro, NC

This is a great "peace of mind". The power went in my area once for four days and I wished I got this generator back then. This unit powers the whole house with no effort. Runs on natural gas and is very quiet. The person who installed it is fantastic, he said he will service it once a year just to make sure its running the right way. I tried it out for a week, just running the generator and I was very happy with the performance. I have a lot of equipment for the physically challenged and really need all electrical sources to run properly. I don't want to be stuck with out power.

We have had this generator for 5 months and it was installed when we built the house. We had some storms come through this weekend in Mississippi and were able to use it for the first time. We were out of power for around 1 hour while we used it. It cycles once a month per my settings and when power goes out you will have power from generator within 10 seconds. When power from utilities comes back on there is no loss of power at that time. Only when you loose power, the reason is generator must warm um before it takes a load. Awesome product and for the price and performance of this unit it's a winner for all.

Have not had a loss in commercial power since installation (naturally) but unit starts well on auto start cycle. I installed cold weather kit, so far the coldest temps at start up have been + 20 f and start up was fine. Hope to get a day below zero and see how it preforms. Don

I live in the Turks Islands. We lose power frequently and we considered buying a generator for years. Luckily i waited and purchased a gereac model. When we lose power the transition is almost unnoticeable. Within seconds the power is on. I have two central air conditioners, one split AC unit and all the normal household appliances. 22kw guardian seriesunit powers it all. The unit is very quiet too. Down side. When we lose power all my friends come over and empty my wine cellar

The installation was a fire and mechanical hazard. 1. Putting the garage door down ripped the wires down causing the door to get stuck. 2. The garage door spring cables rubbed on the power lines - creating a fire hazard. The installation is being redone. I may change my review after the problems are corrected.

Actually, aside from it looking good, We have no idea how well it works. We have not had any type power outage since installation. Further, we have attempted to "be there" when the unit initiates its bi-weekly "process". As yet have we heard it start up. Therefore, we're unsure if it works. We've contacted the consultant and he checked the time & date and the schedule and pronounces it "good to go". so, at this time, we are in a "wait & see' mode.

I had this Generator installed about 4 months ago. The power failed only once since then and the Generator kicked in within 10 seconds. We hardly noticed the power failure. If this Generator continues to work like this (with proper maintenance) for the next 10 years--I will consider this as an outstanding investment. So far so good.

Power went out for 3 days after the install of our generac generator....ran continuous with no problems....convenience was exceptional of not having to manually start..powered the house with ability to do laundry, dishs and live life as if the power never went out. i highly recommend if you have power outages.....

Generator arrived on time and was in excellent condition. Delivers on every aspect of description. Best price on market after comparing to several other units. Nice after sale offers on warranties and service. Would recommend to anyone. Installation was uneventful and operation after install was flawless.
