Got the unit about 11 months ago. Haven't had any power outage yet. It runs once weekly as it's supposed to. I did turn off commercial power a few weeks ago to test. Couldn't do it long enough to test the power shedding to the furnaces. But no issues yet.

Quick efficient installation, trim design, easy to contact installation contractor. This is a high quality product and we do hope it meets our needs should we loose our electricity, especially where we have a handicapped person who needs medicine refrigerated daily.

This is probably the best insurance I could have gotten to avoid an outage. My neighbor purchased the same model 4 months ago. During an outage 2 months ago, I went out to get the paper and noticed they had electricity thruout the house. Only house on the street with power. That sold me.

We had the 22kW Generac installed the Autumn of 2016. Our 1st power outage of the season occurred a couple of weeks ago. The outage started at 10:30pm, just as everyone was prepping for bedtime. 10 seconds after the outage begun we had FULL power. No problems, the generator shut down automatically after residential power was restored, and our electric service was automatically cut over to AC. WOW !! No more lugging out the portable generator!. We also installed the battery heater and oil filter heater - cold climates.

Purchased at the right time,researched price,quality and performance ..picked Generac and experienced a power outage for 5 1/2 hours. Transferred over and back without a hitch.(mother in law was home and didn't notice anything). One of the best investments i ever made.

We now enjoy the security of knowing that, come what may, we will no longer be "left in the dark" during bad weather or hurricanes. We have been considering this purchase for ten years, and are delighted that we finally had the whole-house generator installed.

Bought two and had them istalled by certified electrician. Had a little electronic issue on one unit and and called generac support. Isolated issue and they had warranty man on location and the issue was fixed in two days from the call. All equipment will have problems from time to time. I will use generac for my office shortly as support and warranty follow up were excellent

We had a generac generator at our last house for 7 years, no problems. We have only tested this unit so far, no power outages yet, but tests were good. Only one problem, the load shed modules do NOT work as advertised. The specs say it can "disable" a circuit while on generator power. It cannot do this. It can disable the circuit in an overload situation only. We needed this feature to disconnect our solar panels while on generator power.

This is one product that you see advertised that will live up to the standard it's advertised to and then some,the peace of mind it gives you is priceless, it looks good,easy to install, works as good as advertised,really works better than advertised, you need to get one for the peace of mind it will give you!!!!

This is the second Generac generator. I move away from the first that was a 20KW on natural gas. I had no problems with it during the 7 years it was in service. I installed a 22KW on propane as soon I got settled here. No problems with this unit in the three months since installed. In Oklahoma we are subject to power outages any time.
