Rated 5.0 out of 5 by 6 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 Great units and quiet We own four of these models and they have been exceptional, we have two office locations where one of each is located and in that rual area we have power outages all the time though the power company has gotten better since the storm. However outage do occur, down time is not a option for our web development and hosting company. The Generators we have are about three years old and still doing great we do regular oil changes. I'm a electrician and the installation was pretty easy at my home and the office buildings. Fuel consumption is really good. I do recommend buying a generator that is i bit larger then what you need at this time. This is because we have added on to our house twice and I have a shop next to my house and these are expensive investments so doing it once is the way to go . The great thing is, even if you buy bigger then you need right now. It just mean the alternator aka generator does work as hard under load. Just make sure you purchase the right size. I've had to tell a few people they bought the wrong size for what they want to do. The other two generator operate the whole house not just the freezer and washing machine. The stove is 220 the heating unit and AC is 220 the hot water heater is 220 the dryer is 220. Just do your homework and you will be well pleased. November 13, 2010
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
Rated 5.0 out of 5.0 by Excellent producy After getting hit by Hurricane Irene, we were without power for 3 and a half days. This generator ran out entire house and we didnt miss a beat. Worth every penny August 31, 2011
Rated 5.0 out of 5.0 by It is everything the dealer said it would be. the power has been off 2 times in the last year and everything in my hog barn worked great. October 7, 2011
