Why Rowform ExistsWhy Rowform Exists

A failed coil is already
enough of a problem.
A failed coil is
already enough
of a problem.

Sourcing its replacement shouldn’t become another one.

Working in commercial HVAC, I saw how a failed coil could turn into weeks of avoidable back-and-forth. Measurements lived in notebooks, drawings in inboxes, and critical answers were spread across too many conversations—all while the building still needed to get back online.

I started Rowform to make ordering custom commercial coils a more straightforward experience. We’ve built a connected system that carries your project requirements through quoting, drawing review, and delivery, keeping the details of your order together in one place. You can submit what you need, review your quote and drawings, and follow your order’s progress without chasing updates or piecing together email threads. It all serves one goal: getting coils built to your requirements with less work on your end.
