  • Beat purchase
Best purchase of the year. I was worried buying it my own vs a supplier that forces you to use their install. Came out $2,000 less overall with doing it this way. Was very satisfied with the delivery and the product is now installed and has already been triggered three times due the storms. Working as expected. ... show more

  • Generac to the rescue!
I just bought a new 22kw Generator to replace one that I had for over ten years. Is a life saver when you really need it.

  • Laura has worked our Generac!
Our Generac is 15 years old and is a 17 kw Guardian, It has been on non-stop since Thursday 1am when Laura made landfall and our power went out. We have had power and its running very well but hot, for the last 5 days and have been told that our power may not be on for at least 4 weeks. Hurricane Laura has devasted SW Louisiana like no other storm I have ever seen. We were lucky to not have home damage and the only house on this street that has a standby generator. ... show more
