The Maddox Advantage

Warranty
Nobody repairs like Maddox. Every Maddox repair job is backed by our 3-year warranty.
Purchased a step-up transformer from Maddox knowing nothing about them...These guys went above and beyond on top of excellent pricing. I honestly could fill this up with nothing but good things to say. If I could give them 10 out of 5 stars I would.
We had a customer who lost their primary transformer in the middle of the night. Maddox was able to get a temporary transformer on site in hours. They also rebuilt the damaged transformer in record time while no sacrificing any quality. We were able to install and power up the transformer with no issues. The transformer was phased properly and the rotation matched the previous transformer. I would recommend Maddox to anyone for transformer needs.
Greg went OVER AND BEYOND to get us what we needed on a holiday weekend. Without his assistance, our operation would have been in serious trouble. He helped us find the correct transformer and coordinate a pickup from the warehouse all within an impossible timeframe. Thank you thank you. Will definitely use Maddox for any future transformer needs.
I have purchased many pieces of equipment from Maddox ranging from 1000 kVA transformers to 10,000 kVA transformers as well as fused and non fused load interrupter switches. I am happy with the cost and the lead time which has been perfect for the fast paced schedules with tight budgets we have been facing. The customer service has been on the spot when questions arise.
