Why Connecticut plants mail this repair to us
Connecticut runs a lot of precision machining and aerospace components work, plus submarine and defense work — all of it dependent on control hardware that fails long before the machines around it do. We take units from Hartford, Bridgeport, New Haven 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 ~3–4 business days of ground transit each way and 3–5 business days on the bench, most Connecticut 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.

VFD Repair (ABB, Yaskawa, Danfoss & More) in Connecticut — common questions
How long does shipping take from Connecticut?
Ground transit from Connecticut to our Dallas–Fort Worth lab typically runs 3–4 business days each way. With 3–5 business days on the bench, most Connecticut customers have their repaired unit back inside two weeks — and overnight shipping plus rush service compresses that to days when a machine is down.
Do you really serve Connecticut, or do I need a local shop?
We repair units from Connecticut 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 Connecticut?
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.
