How a leading HVAC manufacturer cut selection cycles by 70% with MileSoft
An EUROVENT-certified AHU manufacturer replaced an Excel + Word selection process with MileSoft's HVAC Selection Suite — and shipped accurate, branded proposals in hours instead of days.

Headline metrics from the deployment.
The Challenge
What needed solving
- Selection process spread across Excel sheets, vendor catalogs, and tribal engineering knowledge — every project required 3–5 days of cross-checking.
- Quotations regularly missed sub-components or used outdated pricing, leading to margin leaks and post-PO disputes.
- Audits were painful: no audit trail of which performance numbers were used or when.
- Sales engineers in 4 regional offices each kept their own version of the calculator — different teams shipped different specs for the same project.
Our Approach
How we delivered
- Replaced spreadsheets with the MileSoft AHU Selection Software as the single source of truth, hosted on the client's intranet.
- Loaded their full coil, fan (3rd party fan suppliers), and damper libraries; mapped each item to certified performance curves.
- Layered the Lifecycle Cost Analysis module so engineers could compare equipment options on TCO, not just first cost.
- Built role-based workflows so sales engineers configure, technical leads approve, and procurement auto-generates BOMs.

Technical building blocks
"Selection used to be the bottleneck of our entire sales motion. With MileSoft, what took my team a week now takes an afternoon — and our submittals are tighter, more accurate, and audit-ready out of the box."
