Bought this a month ago and so far I'm fairly satisfied. Have had a couple of problems with it and still haven't received in paper my paperwork for my 10 year warranty

Smart purchase

The purchase and installation process were very easy and professional. I've had two occasions since the installation to use the generator during multi/hour power outages, and it has worked like a champ.

Generac Home House Generator

I recently purchased the 18k whole house generator due to the recent weather events and various power outages. I like the Generac reputation as well as the warranty.

Great upgrade/replacement

I bought this a month ago to replace my 21 year old 16K unit that had developed a gas leak. Didn't want to invest $1400 in repairing that Old of a unit.

Good reputation

Kent Snider of Morgantown electrical contractor installed my generator. He was excellent,courteous and professional. He answered all our questions and went out of his way to our assurance of satisfaction.

Solid Unit

I have had my unit installed for 731 days. Through 2 power outages it performed well. The first one lasted for several days; shutting it down to rest and change the oil was easy. Being able to monitor the unit with the mobile App is a great feature.

Good Unit

Unit installed a month ago. It starts when needed for a power outage but will not exercise automatically. The noise level is acceptable and unit starts quickly.

I feel like I can relax when there is a power outage caused be a winter storm or wind storm which seem to affect the power quite frequently in my area. I no longer worry about losing my heat in the winter.

Peace of Mind

Had this generator installed in April 2026 by Wayne Cook Electric and I am so happy with the product and the installation company. Nothing but praises for this experience and the installation company!

Eases power outage PTSD.

Haven't lost house power since the Generac was installed so don't have any actual use data as yet. Weekly test firings have occurred and seem normal.
