For decades, commercial HVAC contractors have relied on hand sketches, clipboard forms, and field notes to size and quote replacement coils. It’s a system that works—but only just. Paper gets lost. Key dimensions get missed. And sales reps are often left chasing critical details to finalize a quote.
We thought there had to be a better way. So we built one.
MyCoilSpecs is a free, web-based tool from Tillman & Associates that makes coil replacement quoting faster, cleaner, and more accurate—for both contractors and our sales team. Whether you’re replacing fluid, evaporator, steam, or condenser coils, MyCoilSpecs walks you through the critical measurements and generates dimensional diagrams right from your phone, tablet, or computer.
Built for the Way You Work
Instead of jotting measurements on a form or napkin, MyCoilSpecs gives you:
- ✅ A guided quote form combining field-friendly layout with factory-level production details
- ✅ Required fields clearly marked for fast, accurate quoting
- ✅ Dimensional ID images to eliminate confusion on what to measure and where
- ✅ The ability to fill out only the basics for a quick quote—or go deep for a production-ready spec
