No losing power anymore.

After last winter losing power for 4 days and the house temperature went down to 42 degrees, I said I am buying Generac until to do my whole house.

Not finished installing

Generator is fine the installation isn't finished and some of the insulation that has been done was done wrong

Terrible product

I purchased this a year ago and it has never worked. It stalls out after 30-60 minutes with each outage

Everything I expected and more!

I bought this unit a year ago and I am very pleased with it. It is robust, dependable and the dealer gives excellent service.

It is a rather attractive device.

My unit was installed in July 2026. I am glad I made this decision and don't have to worry when/if the power goes out.

Great Unit But?

Recently replaced my 20 year old generac. New one works great. Still can't afford monthly interactive fee so we lose all that capability.

Replacement for a 19 year old unit.

I bought this unit as a replacement for a 19 year old 17 KW that served us faithfully until the fiber oil pump gear disintegrated and left the room.
