What we see from Houston
Houston is built on oilfield equipment manufacturing, petrochemical and refining operations along the ship channel, and the heavy fabrication that supports them — process environments where drives and operator terminals run continuously and hot. That mix decides which controls end up on our bench: oil and gas equipment, petrochemical, refining and heavy fabrication all depend on operator terminals, drives and power supplies that reach end of life long before the machines they run.
With roughly 1 business day of ground transit each way and 3–5 business days on the bench, most Houston customers are back in production well inside the lead time quoted on a replacement unit. When a line is down, overnight shipping plus rush service compresses that further.
We are not a local depot in Houston and do not pretend to be — this is a mail-in service run from a single bench lab in Arlington, Texas. What that buys you is a technician who repairs these units every day rather than one who sees one occasionally, and the same 24-month warranty wherever you ship from.

Part numbers we repair for Houston customers
PowerFlex VFD Repair in Houston — common questions
Who pays shipping from Texas?
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 Texas 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 Texas, overnight shipping plus a 1–2 day rush bench typically beats any replacement lead time by weeks.
Can Texas plants set up a commercial account?
Yes — maintenance teams and integrators in Texas can open a commercial account for PO acceptance, priority queue, and repair history by serial. It's the same published pricing, with less friction on every subsequent repair.
