Rated 4 out of 5 by from 24KQS is much noiser than or other one 24kQS ruin much louder than our other one, our other one is a 22kQS about 8 years old and you have to walk up to it and place your hand on it to confirm if it is ruining. The New one you are able to hear 200 ft. away. The installer thought it was normal and said the stander is much nosier.

Rated 1 out of 5 by from Engine funny noise at start up The engine at start up had abnormal engine noise at start up that goes away after a couple minutes run time. The certified Generac tech who helped at unit start up acknowledged he never heard that sound before. We have just started the process to diagnose and fix the sound so I cannot give a full rating until it is fixed. Overall, when the initial abnormal engine noise goes away, it is a very quiet unit in my opinion. I am sure I will be able to give a 5 star and excellent ratings after it gets fixed.

Rated 5 out of 5 by from Great Product We hope that it will never be necessary to use but with living in a state that has a history of tropical storm and hurricane threats, it sure does make us feel more prepared.
