Having the largest transformer inventory in the USA doesn’t help anyone without the team behind it. At Maddox we pick up the phone when you call and ensure you get the transformer you need when you need it.

Mac and his crew did an absolute fantastic job installing my transformer. I had a transformer fail due to the heat and age, but Mac quickly had a replacement for me at a great price. His team did a bang up job getting it on my site, so we could get it installed. HIs team saved me a week of downtime and lost product. We will be using them again in the future! Thanks from the team at Great Western Malting at the Port of Vancouver. -GWM Maintenance Manager

It's been a pleasure working with the Maddox Team. Equipment pricing is competitive and staff expertise is strong. Our initial purchase of 4 large Transformers has gone seamlessly. Considering we are engaged in a multi-year purchase of transformer replacements across our communities we remain confident that this project will continue to be successful due to our work with Maddox.

I wasn't sure what size step up transformer I needed. Called the tech support line and these people are great. Very hepful and friendly. Unit shipped following day after the order and arrived soon after. Great product and company. I highly recommend and will use them for future purchases. Thanks Maddox!!

In a post Covid world where nothing is available in the construction market, Maddox Industrial Transformer had what I needed. Reasonable price and fast shipping. Pretty shocked and pleasantly surprised to find a company that still values service and support. Thank you for your help.

I’m thoroughly impressed. The transformer arrived 3 or 4 days after ordering online. It was well packaged, and well constructed. I’ll definitely use Maddox the next time I need a transformer.
