This is my first purchase of a whole house generator, I can not comment on reliability because installation was just completed. What i can mention is that i liked the fact that i did not have to worry about anything. The sales team was responsible for everything, they called and scheduled the utilities for identification, pulled the permits and scheduled the gas and electric companies to make the required connections. I would also like to mention that the people that did come out to perform maintenance were very knowledgeable and professional. Highly recommend this product and this company.

Purchased the unit from Perkins Generator Sales and Service in Sharpsburg Ga. The unit was delivered and installed within one month of our initial agreement to purchase. The installation and start up crew led by Cody did an outstand ing job dealing with the local inspectors and keeping us abreast of the progress, The startup was completed flawlessly and Crody walked us through the commissioning process. The support from Brian, the home office sales representative was outstanding and efficient. I highly recommend Perkins and Generac, the Generator team.

Installment was not difficult. Features are well defined. Manual not hard to read but does require someone who is knowledgeable in the electrical field, not a novice. Price was very reasonable. power went out 3 times while we were waiting for it to get hooked up. we were glad then that we had purchased this unit.

We installed a 15Kw unit 13 years ago, virtually trouble free operation. We decided to upgrade to a 22Kw unit due to the age of the first installation. The new one is quieter, the power is more pure and we now have load control for managing the HVAC system. The WiFi monitoring is great! Smooth replacement installation.

With young children in my house, I don't want to worry about keeping them warm in winter or cool in summer. With everything powered these days, including cell phones, that we use exclusively for communication... I can't afford to be without power. Food in refrigerator and freezers will not spoil. Life will go on "normally" in the house when the power goes out. Having a whole house generator installed, lets me not worry about a power outage anymore. So glad that Generac makes residential generators... it will last.

I'm an engineer for the DoD and we have been using Generac products for years on our builds so I know first hand the quality and dependability. We've only had our home unit for a few months now but it's nice to have that peace of mind should a hurricane or storm come our way. Definitely worth the investment.

The whole house generator works exactly as advertised. The available whole house surge protector from SPS is wonderful. I can now get rid of all the other ones scattered around the house protecting various electronics. Specialized Power Services is customer focused and did an excellent job installing and explaining its features. Two refrigerators and a chest freezer no longer are a concern when the power goes out from falling trees and best yet - our spa is useable. No more gasoline powered generator, attaching it in the rain or snow, to run some products e.g. furnace and a few selected items.

I bought this product about 10 years ago after a particularly severe storm knocked out power for two weeks in my area. Since then, in the thousands of hours when I did not need it, it seemed to work perfectly. During the three periods when I did needed it, it did not work at all. During one storm, with a 10 day power outage, I was able to remove the oil pressure sensor and put in a plug and I was able to get the machine going and it worked OK. Without someone making that suggestion, I would've been out of luck. Service was impossible during that period.without me jerry-rigging a repair in a snowstorm. Service in my area is very difficult, delay of two weeks defeats the purpose of the generator completely. I would not buy this generator again.

I have a 16 k generac generator that I bought in 2006. Never gave me any problems, except that the base it's all rusted. I'm going to give it to my nephew, so he could get a new base for it and install it at his house. I just bought a new one 18 k and I love it. Hopefully this one doesn't get rusty. Maybe I'm asking for too much because my 16 k it's almost 16 years old. But in general I'm very pleased with the performance. I do recommend Generac.

Our new unit was installed today by an efficient, professional and extremely courteous team. This new generator gives our family a peace of mind with the upcoming northeast winter. I have recommended this product to many of my friends hoping they will realize the value this generator will add to their home security. I should have made this decision five years ago, yet so happy it is installed now !
