What Customers Are Saying

The generator is described as powerful, reliable, and able to power a variety of household appliances during outages. Many users praise its easy starting and ability to run for extended periods on a full tank. However, some experienced issues with the GFCI breaker, CO2 sensor, and insufficient power output. A few also found the generator to be too loud and had difficulties with assembly. Overall, the generator appears to be a capable and generally positive performer, but customers should carefully consider their power needs and be prepared to troubleshoot any potential issues.

Generac generator

Had problems with product right from the start. Could not return product to Lowes out of the box.Took it to get repaired under warranty. Repair person is having trouble getting an answer from Generac as what to do with the issue. It's been a week since I took it in. Not very happy with product at the moment.

The generator was shipped ok, But had to call lowes to have a repair person to come out and show me A) to use it. B) and make sure it works before he was gone from my house, Because if it did not work I wanted the service person to take notes of this and to have it fixed now or to have it returned!

Lowe’s has poor customer service.

Would Not Recommend

One of the handle grips were missing. I went back to Lowe’s a week after purchasing to get a grip. The store manager Mike Foster would not give me one of another generator. He told me that I needed to call Generac. That is poor customer service.

Frustrated! Generator for Storm

Would Not Recommend

Bought generator upon threat of storm knocking out power. Bought a few days prior assembled and started upon completing installation. Brought it down to where it would be used and thought I would test it out. Good thing because it never would keep constant voltage! Called Generac 1-800 number and tried to troubleshoot to no avail. Provided a local number to service. Because it was a Sunday only provided a message would call Monday morning. I called Lowe’s and said I could exchange it for an...

The right features at the right price

Would Recommend

I was facing an ice storm and living in an all electric house, with above ground power lines and 3 people in the house who would not be able to rough it should we face a prolonged power outage. Generac is a brand I trust and Lowes got emergency shipments at the store on at least 3 days leading up to the storm. The limited assembly was easy. I like that you can burn multiple types of fuel. The electric start worked like a champ, and I like that it has pull start as well. The shipment my unit was ...
