Rated 5 out of 5 by Best purchase I ever made I purchased my GE Generator System after a visit to a 55+ Expo at Dover Downs in Dover, DE. I had thought about a generator and wanted a quote on purchasing one. While at the Expo I meet Nick Sebastian from Towles Electric Inc in Smyrna, De.. We set a appointment and Nick could not have been nicer. We purchased a 20k whole house generator from him. After Hurricanes Irene and Sandy 2 year's in a row I wanted peace of mind, that's what Nick and Big Bertha ( our generator) have done. I LOVE LOVE my generator, when the power is out we are comfortable and safe in our home. October 8, 2014
Rated 5 out of 5 by Satisfied Customer Generator and Transfer Switch ships directly from Briggs and Stratton plant in Wisconsin. Product was delivered to house on time. Hired an electrician to install and a GE certified dealer to oversee installation and start up. Electrician had no trouble installing it and GE dealer (Houston) was great to deal with. Don't cheap out on the installation and be sure to sign up with a local dealer for the annual maintenance contract - it is well worth it. Generator performs a weekly self-diagnostic check and runs for 20 min. Very satisfied with this purchase. Wireless monitor works well too. Note: Air intake is on the right side and discharge is in the front on left side (see attached photos) November 14, 2013
Rated 5 out of 5 by This is my Dream Generator! Right now we only have one of those old gasoline, Really LOUD generators and although I've been grateful to have it after Tornados and Ice Storms, I would love to get one of these Beauties!I read about the specs after entering my house size, etc and then I have been reading the reviews of the people who have one of these. It sounds Amazing! I worry about some type of diaster happening, maybe even the power grid failing and in addition to not being able to buy more fuel for ours in that scenario, the Extreme Volume of our generator lets individuals with bad intentions think that if you're running a generator, then you must have something to protect! Namely Food! I have a little stored back but not enough to get through 6 months much less supply hoards of people who didn't even store back a few packages of Ramen noodles. I am excited about you offering financing and hope that soon I may be posting a New review about how well our GE Generator performed this coming winter! Thank you! September 6, 2014
Rated 5 out of 5 by "Life goes On ! I purchased this generator over a year ago in response to the ever changing weather patterns we seem to be victim of. I wanted dependability for my wife in the event of my absence (being a fireman) and as I tell my wife "life goes on for you" during any power interruption. Cooking, washing, drying, AC/ Heat pump, you are all good to go thanks to my 20K GE Generator. June 23, 2014
Rated 4 out of 5 by Solid solution for large homes, and no worries I wanted a whole-house unit that could run everything and do so reliably. This unit’s 83.3 amps of power is more than sufficient for my multiple refrigerators, two HVAC units, 3 dishwashers, sump pump, tons of electronics, electric car charging, and so on. The transfer switch automatically and safely switches the unit on and off quickly and has worked very well for the times we have needed the unit. Only complaints: had to increase the amount of natural gas coming to the unit by increasing the meter capacity and the line size to the generator. Also, the remote control “loses” its connectivity to the generator every once in awhile for no apparent reason even though it is less than 10 feet and one wall away from the transmitter. May 12, 2014
