Warranty
Nobody repairs like Maddox. Every Maddox repair job is backed by our 3-year warranty.
I have purchased many pieces of equipment from Maddox ranging from 1000 kVA transformers to 10,000 kVA transformers as well as fused and nonfused 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. Maddox has helped me meet budget and schedule. The equipment meets our rigid specifications. The customer service has been on the spot when questions arise. Maddox has been competitively bid with other gear manufacturers and even when cost is similar their lead time has been the deciding factor for my purchase orders.
We worked with Maddox most recently to repair a transformer at our site. Cameron and the repair team were very communicative, professional, and understanding of our needs to get back online as quick as possible. We are very impressed with the level of service we received and look forward to working together in the future.
Worked excellent, tech support was incredible with helping me figure out what I needed as well
We've bought numerous transformers from Maddox. Excellent service both before and after the sale. The rebuilt units are coming out looking like brand-new transformers. No surprise up-charges, no problems in shipping. Highly recommend!
We ordered a unit from Maddox that had a very small leak on a weld on the top of cabinet. These things are going to happen I understand that. The unit was time sensitive to one of our customers. The Maddox Team went above and beyond to make sure they fixed the problem, got it delivered back in time! Now key factors in this was communication and they were honest and upfront keeping their word. That goes a long way in this industry. Thanks again for great customer service !!
Very responsive to inquiry, prompt shipping, protective packaging, on time delivery. Will be back!
Wonderful service. Very responsive, offered all the guidance, and really stayed on top of it (I mean, really did so - send at least 10 emails on confirmation, status of the order, invoice, delivery, instructions on how to receive etc). Shipping was lightning fast (to Dallas, Texas) and without a single issue (this is not the first time I ordered commercial equipment, and every time it's a hassle). I couldn't find the unit for the same price anywhere. Overall, fantastic. I wish all companies cared as much about the product they sell
