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.

Rated 1 out of 5 by from Delivered and would not stay running At start up the unit would not stay running. The installer went through all error codes and finally had to call the help line. They went through several procedures to get the unit to produce electricity to no avail. They finally agreed to have a factory technician come out and try to find what is defective. This will not be attempted until next week. No definite day was communicated. At this point we have a defective unit that will not run and the possibility of stormy weather coming next week. Concerned at this point with the amount of investment and the potential of a defective product.

Rated 5 out of 5 by from Glad to have this installed So happy to have this generator installed as there are currently two storms heading this way next week. Gives us peace of mind that we can keep our home running even in a power outage. Installation was easy and everyone that worked here was helpful. Hoping we won't need to use this much!

Rated 3 out of 5 by from Horrible Install, No Wi-Fi interface I purchased what was sold to me at the "TOP OF THE LINE" for generators. I expected to be able to get an online portal or some type of remote access to see when the unit ran and ensure there were no issues. We live in South Louisiana and I need to know that when we need this unit to work it will do so. However, there is NO PROACTIVE notice of the status of the unit. YOU MUST go to the panel and read the status. PLEASE CREATE A way to remotely access this unit.
