Rated 5 out of 5 by from Worth the Investment Such a relief to have in a hurricane-prone rural area. What an amazing feeling when the Generac came on after a power outage during the night in a tropical storm. I could go back to sleep without concern.

Rated 5 out of 5 by from Easily powers my whole home I live in north Louisiana, and while we don't get the beating the guys do down south from hurricanes we do get a ton of tornados, high winds, and torrential storms, and we lose power all the time, often for days, due to our antiquated power infrastructure. Instead of waiting on AEP to fix themselves, I decided to take steps to correct the problem myself and get a Generac 24kw whole home generator installed by Precision Mechanical Power out of Bossier City Louisiana. They did an incredible job, and the generator easily powers my whole 4k square foot home including 2 central ACs. I work from home and have a older Dad who has health issues, so the peace of mind this generator gives me is amazing. The value to cost ratio was perfect, and I highly recommend Generac and Precision Mechanical to anyone in the Northwest LA area!

Rated 5 out of 5 by from Absolutely amazing Yesterday we finished the install, and inspections. What an amazing product! Not only is the generator amazing with all its features, but the installation was great. Generator Supercenter in Denton are the best people to work with. Everyone from the people in the office, the managers, and all the different specialist that came to the house were so wonderful to work with throughout the process. Special shout out to Peter, Chad and everyone else. I feel very well protected now and I’m not worried about power outages anymore.

Rated 5 out of 5 by from This generator is great. it is an answer to our prayers. As a disabled Veteran I am unable able to negotiate the stairs in our house, my wife has to try and push me up the stairs. With the whole house backup generator we no longer have to worry about power to run our elevator, if there is a power outage.

Rated 5 out of 5 by from Love my new security from South Louisiana Hurricanes! I’ve been waiting a long time to purchase my Generac Whole Home Generator. Having my new generator gives me a great sense of security. Since I was a child with Hurricane Betsy, we’ve never left our home for any of Louisiana’s hurricanes, We suffered thru the power outages and the heat and lots of ice chest full of food and drink. Pulling electrical cords and fans thru our home. And now we’ll be living in absolute comfort from the moment our power goes out to the moment our wonderful lineman restore power to our grid. Thank you Generac for having such a necessary product at a very affordable price.
