CUSTOMER REVIEWS

Rated 5.0 out of 5 by 5 reviewers.
Rated 5.0 out of 5.0 by Our Generac has performed perfectly Outstanding product. Dependable unit. Generator has performed perfectly on several occasions. March 27, 2014
Rated 5.0 out of 5.0 by Godsend Just had it running a full week thanks to Hurricane Sandy. Worked great -- although stopped for oil (lubricant) after five days. Fed it four quarts and we were back to the races. Can't imagine how awful the week would have been without it. November 8, 2012
Rated 5.0 out of 5.0 by One of the best investments that my wife and I have ever made. In the 30 plus years that my wife and I have lived in our house, we have experienced many power losses including an ice storm in which we went without power for 37 days. The Guardian whole house generator has within the last several years in which we had several major power interuptions has worked without fail. It has proven highly dependable during the many short periods of power loss that we have experienced as well as two major outages over 7 days. Compared to the ice storm experience, it is great to not only have warm showers, but to enjoy hot coffee and breakfast in the morining and hot meals in the evening. As we have now entered into retirement, my wife and I highly recommend the Guardian whole house generator that results in the avoidance of having to worry about keeping the house comfortable in both cold and hot weather while carrying on with our normal daily lives. The generator not only requires very low maintance, but the panel on the front of the unit quickly provides you the necessary information as to the status of the unit's operation. I give a "well done" to the Generac Company. October 11, 2011
