Rated 4 out of 5 by from Very quite This is my 2nd Generac generator. The first one was air cooled and was very loud. It lasted about 3 years before it burned up. A rep from Generac came out and confirmed it could not be repaired. My current one is a Qs 38KW in the liquid version and is very quite. It has only been installed for about 3 weeks now so I can’t say much about its performance. I can say I ordered it in April and only got it installed 3 weeks ago. Long delivery time along with an elevated structural platform, city permits for natural gas, electricity and a general construction permit in a flood zone. Be prepared to spend $30plus thousand dollars by the time it is up and running. Estimated cost to run it on natural gas is around $140 per day. We live on the Gulf Coast and are subject to major storms every so often and have lost electricity several times for short periods. It gives us some comfort that when or if we are out of town the Generac will protect our household from such an outage. Thanks

Rated 5 out of 5 by from Peace if Mind We have not had to used it yet. We like the peace of mind that our last generator gave us when we lived near Houston. This is a bigger unit and the first to have limited monitoring with an app. Wish it had on and off feature.

Rated 5 out of 5 by from Love the Mobile Link App Being able to keep tabs on my generator & knowing what is happening with text notifications gives me the peace of mind whether at home or on the road. It’s a great investment & the generator has our home prepared for whatever life/Mother Nature throws our way next.

Rated 5 out of 5 by from Reliable Power This product delivers reliable power. We have recently moved from Deep South Louisiana to North Carolina. We had a total of two generator in our time in NOLA as we updated after our original one pasted the 10-year mark. During Hurrican Isaac, we were without power for 8 days. We had power within a minute of the grid going down and didn't miss a beat until power was restored on the grid. We have recently placed a generator on our property in NC and have great piece of mind that we will always have power even if grid power is not available. We used Power Source for our purchase and installation, excellent service!
