Rated 5 out of 5 by from Great product! The company I used did a great job installing the Generator and removing my old one. What wasn’t done at the initial installation was handled by the company within 4 days. And the generator is quieter. The only suggestion I have is that the new transfer switch is completely locked and does not tell you if the power is out and when it comes back on. The new generator seems to be very automatic - I think more user friendly.

Rated 5 out of 5 by from Delivered as PROMISED I have been pondering a Generac purchase for a few years. After hurricane Harvey I really got serious about doing my homework. The sales staff did a great job of bringing me up to speed quickly; And, once the generator was setup, the features were amazingly simple to understand and use. When you make this type of purchase the last thing you want is to get another set of “to dos” on your list. The Generac generators run themselves while providing peace of mind.

Rated 5 out of 5 by from They fixed it! This is actually my second review. At start up the generator would not keep running and produce electricity to the house. We were quite worried. They sent out Jeff and John to try to make the unit perform. They were GREAT. They had several gauges to test the unit and after 3 hours and several calls to Generac, they replaced several components and we tested the unit. They stayed through the startup procedure with the contractor to make sure it worked properly. The unit performed perfectly and we are impressed with the unit and the factory service. Jeff and John were very knowledgable, professional and great to deal with. We have every confidence the unit will operate flawlessly now and in the future.

Rated 4 out of 5 by from Great product BUT Customer Service was lacking We purchased the Generator but have not had an opportunity to use it as of today. During the start-up we were impressed with how it worked. As of now, I would recommend this product. But the customer service in the particular office we went through needs to work on their communication skills. This is a very important part of purchasing an item of this importance!

Rated 4 out of 5 by from Poor lead time for delivery I ordered a 27KW liquid cooled generator. The order was placed with a local distributor, who I have done business with in the past. The generator was ordered 1si week of June, with quoted 4 week lead time. I finally got the generator on 8/19/2020. I actually called Generac on 8/17/2020 to ask a fairly straightforward question: In Generac behind in production of 27KW liquid-cooled generators. I could not get a satisfactory answer to a question I thought was fairly simple.This one thing, failure to deliver in a timely manner, may cause me to reconsider recommending Generac.
