Rated 5 out of 5 by from Upgraded 38kw Upgraded from a Generac 22k that ran flawlessly for 12 years. Product as described and very quiet. Larger in size of course to the previous 22k liquid cooled, but very pleased overall. Runs great and customer support was very helpful.

Rated 5 out of 5 by from Just installed it - only a test run so far. I am building a new house. This 38 kw machine should come in real handy since we are in the middle of a heavily wooded 3.5 acre property. It certainly seems like it will do the job.

Rated 5 out of 5 by from Plenty of power; lots of security I wanted a system that would be reliable and ready whether the next outage was in a month or in five years. I wanted a system that would run for ten minutes, or for ten days if necessary. This system will do that and support my whole house. With a 1,000 gallon propane tank, I am not dependent on the electric grid or the natural gas supply system. All I need now is a water well.

Rated 5 out of 5 by from Best in the Business Generac produces the best natural gas generator in the business, I am a Snow Bird and just installed my second Generac generator. I hope that I never have to use it.

Rated 4 out of 5 by from Quality Control I love the generator but they have factory quality control issues. I had water line clamp loose causing coolant leak.. Wire panel wires not seated properly causing issues to transfer switch. Fuel line hose clamp un-attached needing to be put in place and tightened. Lastly had to replace the solenoid to correct fuel pressure warning code. All this on initial installation.
