Rated 5 out of 5 by from Excellent generator and installation TEXXAS POWER LLC did an amazing install and setup on my 26kw unit. Bill, Seth, Nick, and Keith were very professional, on time, and really showed they care about their customers! I highly recommend this company!

Rated 5 out of 5 by from Excellent quality and design We have had our 24kW Guardian unit for just over one year now. We reside in Houston, TX area and are thus exposed to hurricanes, tropical storms, and even winter freezes. Each of these weather events can disrupt power, for a few hours to a few days, or more. I have an 87 year old mother-in-law that lives in a home just over a mile from us. Thus, our decision for backup power was as much for her as for ourselves. Our unit runs our entire 3,100 sq.ft. home, including a 5-ton AC, and a pool. Shock Doc Electrical in League City was referred by Generac and they did an excellent job on the installation. Worth every penny for the peace of mind!

Rated 5 out of 5 by from R3 Hardware Installation We just fired up our new Generac backup generator. I was extremely impressed with the unit and it’s performance. It handled the entire home without any issues or struggles. I would also like to thank R3 Hardware Honesdale Pa and its employees. They have been tremendous throughout the entire process. They are knowledgeable, efficient, professional and extremely helpful and friendly!!! I would also like to add a special mention to Beth for coordination, scheduling and Walter for the installation!!!! They were both amazing and made this a very enjoyable experience!!!

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 Whole house Generator Great service, analysis, recommendations by the team at Generator Supercenter in Tulsa, OK. Turn key service from sales, install, electricians and plumbers. I highly recommend them.
