Why Maryland plants mail this repair to us
Maryland runs a lot of food processing and defense work, plus biotech manufacturing — all of it dependent on control hardware that fails long before the machines around it do. We take units from Baltimore, Columbia, Frederick and everywhere between: the unit ships to our Dallas–Fort Worth bench, gets repaired at board level, and comes back tested under a 24-month warranty.
With ~3 business days of ground transit each way and 3–5 business days on the bench, most Maryland customers are back in production well inside the lead time on a replacement unit — and overnight shipping plus rush service compresses that further when a line is down.

PowerFlex VFD Repair in Maryland — common questions
Do you really serve Maryland, or do I need a local shop?
We repair units from Maryland plants every bit as easily as local ones — mail-in is the whole model. You get the same published pricing, the same 24-month warranty, and bench photos/documentation with the work. Most "local" industrial repair quotes end up shipping your unit somewhere anyway; ours just says so up front.
Who pays shipping from Maryland?
You ship the unit to us with any carrier at your cost (insure it — packing guide provided), and return shipping is selected at checkout: $24.95 ground, $59.95 2-day, or $109.95 overnight, flat nationwide.
My machine in Maryland is down right now — what's the fastest path?
Overnight the unit to our lab with rush or emergency service selected and it goes to the front of the bench the day it arrives. From Maryland, overnight shipping plus a 1–2 day rush bench typically beats any replacement lead time by weeks.
