HVAC: price the job, bottom up

This is the actual Anvil HUD bid engine running this trade's own preset line items and loader defaults. Move a quantity and watch the bid rebuild. No account, nothing stored.

A few of this trade's own preset lines. Set the quantities; rates and waste ride on the researched presets.

The real builder adds your own lines, allowances, and subcontractor pass-throughs, and saves the project.

What you are looking at

  • The same build-up the app runs: each line is quantity times material (plus waste) plus labor, then general conditions, contingency, and overhead and profit on top. Every line is published at /the-math.
  • The presets are researched 2026 US figures, cited at /sources. A new workbench starts with exactly these and you tune everything to your shop.
  • Signing in opens the real builder: your own lines, allowances, subcontractor pass-throughs, saved rate defaults, and a printable client proposal.

Make it your number

The demo prices preset rates. Your material costs, your labor rates, your markup: that is the number that matters, and the engine is free.
