Our Generac generator is what saved our belongings and is what ultimately saved us as a family. There was utter chaos and destruction outside, but my home was air conditioned and I had power.

We searched all over Indiana for the right company. Horizon was by far the most professional, and their installation was flawless. Our generator runs like a dream!”
