We bought this 20KW Generac for peace of mind. We can rest assured that in the event of loss of power we will have no worries. The electrical contractors were efficient and knowledgeable about the product and installation. The installation was professional, the crash course was well explained, good service and easy to use. Money well spent!

In December 2009 we lost power for 9 days in the Northern New England Ice storm. We had to move out of the house into various motels with our pet birds. Fortunately the house plumbing survived the cold, but I resolved then to get a whole-house generator. Now it is in place, I feel secure. We lost power in the 2011 Hurricane Irene, but the Guardian kept us up and running. I was even able to get some important work done from home for a company emergency in the middle of the hurricane!

i have the 20k and had to use it during the tornados in alabama for 4 days non stop. it worked great. i was the only one in our sub division that had elec.it was like we had full elec. power. a/c and everything else ran perfect. the only draw back is that it does use a lot of propane. at least a gallon an hour on a full load. it 's still well worth it. would highly recommend.

We installed the system 3 years ago. There has only been one issue with it when one winter cold snap brought up the need for a cold weather kit. This kit should have been recommended by the installer. No issues since then. In one outage it has ran continuously for almost 5 days without a problem. The one feature item that is needed is to have the system charge the battery while online. Running without a charge for extended periods risks a failed restart if, for example, you stop for a short period to check the oil level.

My husband works for the power company, so when the power is out I'm always on my own. We have had the generator installed now for about a year and we haven't had a power outage, but the features make it easy for me to check the status of everything myself. I like that it tests itself weekly to make sure that it is running properly. Every so often we cut the main power just to make sure that the transfer switch will do what it's supposed to do. This generator was a good investment. Even if we never need it, it was money well spent to have peace of mind.

Every week when the Generac does its scheduled test run, I like hearing the steady thrumming sound -- it spells security. We've had the generator for nearly a year and it has run flawlessly through a couple of outages (several hours in duration). The unit looks good and our dealer did an outstanding job of installing it -- very neat and professional.

I selected the 20kw unit to provide emergency power backup. It has been a blessing in several power outages. I live in a remote area with overhead power lines and storms frequently result in lengthy outages. I know I can rely on my Generac when these occur.

Ralph, Darrel and Adam from Auxiliary Power Systems Inc., Remlap, AL did an outstanding job on installation and start up. I look for many years of outstanding service from my Generac backup standby generator (20k air cool). The generator was installed at our new home in Sawyerville, AL

I researched many different brands and even though some other brands have a 5 year warranty and Generac a 3 year, I still think that Generac provides more value for the money. My installers (Long Electric Frederick, MD and Southern States Petroleum) did an excellent job. The testing of the unit not only ran my whole house but with the base board heat and a/c on at the same time with the dryer, oven, stove top burners, toaster oven, microwave oven and all the lights in the house on provided enough electricity to even run the hot water heater and well pump. The noise level seems to be no more than the a/c compressor when running. Have not had an opportunity yet to see it work in an actual power outage. I would recommend this to anyone with an average 200 amp service. I purchased two 100 gal. propane tanks which will enable me to purchase propane from anyone I want but for now will stay with Southern States.

Researched numerous generators for new home that would provide maximum power at a reasonable cost. Dealer was very knowledgeable and worked with us during the construction of the house to incorporate the transfer switch into the electrical work. Dealer also loaned us a portable generator during a power outage prior to the installation of the permanent generator. Great piece of mind for a very reasonable price.
