Testimonials

On 2/10/2026 Zach Spitzmiller had this to say:
Rush Power has been my go-to for both generator rentals and generator maintenance for as long as I can remember. Their experienced staff has been able to bail me out of every problem I have sent their way over the years. They’re dependable, responsive, and straightforward to work with. Rentals show up on time, in great condition, and ready to go. On the maintenance side, their team is knowledgeable, thorough, and quick to help when something comes up—preventive service or troubleshooting, they handle it. If you want a company that actually stands behind their equipment and supports their customers, I highly recommend them.

On 2/10/2026 Jonah Mundy had this to say:
Outstanding service from start to finish. The team was knowledgeable, professional, and clearly knew generators inside and out. They showed up on time, and made sure the system was running perfectly before they left. It’s rare to find a company this reliable. Highly recommend them for any generator or backup power needs.
