Critical Power Products & Services prides itself on great customer service and high quality results. Below are just a few testimonials from some of our great customers. Thank you for looking!

“As an integrated aquaculture farm, power is necessary to keep our life support systems operating. 15-30 minutes without oxygen can be lethal to the fish in our rearing tanks, so I wasn’t sure if purchasing a used generator was the right option for our farm when I started looking into back up energy systems.

After speaking with Ryan Alt and the team at Critical Power, I am confident that we made the right decision. Critical Power had the experience to identify the best unit for our application, they were attentive, responsive, and they worked with us to save about 40% of the cost versus buying a new, lower quality unit. I happily advise anyone considering purchasing a generator to start with a phone call to the good folks over at critical power.”

Thank you,

“Critical Power Products & Services was an excellent partner to work with. They provided a great offer for our equipment and executed the removal as promised.

“I just wanted to take a moment, now that we have closed out the data center relocation project, to thank you for your part in making this a success. I really appreciate your attention to the project as we approached the our dates. Critical Power’s reputation and experience in the data center material business gave me confidence that we were making the best decisions in managing the removal and re purposing of our data center equipment. Your team’s coordination in removing the floor and A/C refrigerant prior to the removal of the remaining gear made for a very timely and efficient project completion. While I was initially concerned about studs remaining in the floor and small spills from the pipes as they were removed, I was very pleased to see that when you and your team had completed the job and we did our walk through, the floor areas were absolutely clean and safe with all traces removed. It looked wonderful!

I also appreciate the lengths you were willing to go to accommodate the circumstances of our move and timing. It was great to work with you on this project and I look forward to the opportunity to do so again, as we further rationalize our data center footprint.”

Best Regards,

“Understanding our budgetary concerns, as well as the need for a good working unit, Critical Power Products & Services supplied a fully refurbished Liebert HVAC unit with a brand new condenser. Not only were we pleased with the pricing, we also received the unit in a timely fashion. The sales department has been a pleasure to work with, and we feel that the quality and continued customer service is some of the best that we have come into contact with.”
