                      I purchased a Generac Generator 22kw air cooled. Had it 14 yrs. Never any issues. If you keep up yearly maintenance you will Never had any worries. if the Never had a large gas bill when it did run. Comes on once a week to make sure it is running properly. I did have to pay for someone to put a slab for it to sit on. Pay for the natural gas hook up, electrician, shipping charges, and someone to get it from the driveway to the backyard. I would purchase again it my HOA would permit it. Worth having!

                      Order problem

                      Called to order 22kw Generac Generator. Advertised price includes shipping. When talking with sales person I was advised there were 2 generators in there warehouse in Ga. but there would be a $250 freight (shipping) charge added to the advertised price. I DID NOT order the generator and I nelieve this company is advertising FALSELY.

                      Really powerful machine. Power up my entire home!

                      I have been looking for an automatic backup power for a while and I did some detailed search and reviews before I decided to buy this particular model. Me and my wife can't afford any grid downtown time as we both work remotely due the pandemic. We had a small back up generator which is not capable of handling all the equipment and heavy duty air condition systems. This machine work really well without any issues handling everything in my home. Really happy with the performance of the generator. I really wish I had installed one years ago.

                      The machine seems very well built.

                      The machine seems very well built. Runs very quiet. I ordered this machine for my sister. Her entire home run on this beast during outages. No issue at all. She is happy so as I am. Recommended.
