What our customers are saying

This company got it done. There is no other way to describe the dedication from a personal phone call by the president to each and every employee that was onsite. My mom was diagnosed with stage 4 cancer and they literally moved mountains to install a generator quickly and efficiently. They followed their timelines and showed up exactly when they said they would. There was zero headache on our part and we could focus on providing my mom the comfort care she needs. This company was outstanding.

We called Grasten to perform the first service on our standby Generac 38 kw generator. Trevor their service technician was professional and knowledgeable. He reviewed the service requirements in terms of what Generac recommends and performed the service with no issues. It was a good experience all around from scheduling the maintenance to the work performed . We would highly recommend Grasten. Good job!

I've been using Grasten Power Technologies the past several years to perform semi-annual maintenance on my backup generator. I worked with Chris Brade (Service Manager) to schedule service. His team always arrives on time within the specified timeframe, performs all service activities per the contract, and informs me of any potential issues. Chris is always available to answer any questions and provide reasonable solution when necessary. I've recommended Grasten to friends and neighbors. Excellent service at a fair price!

The price was right, the instillation was well done, and Josh Keller did an excellent job making sure everything went smoothly. Completely satisfied.

Just wanted to share that I had a great experience with Grasten. Really friendly and competent people - from their office staff to their field crew. I highly recommend them for your generator needs.
