Built for practical HVAC takeoffs

DuctCount is a free browser-based tool designed to make mechanical blueprint takeoffs quicker, clearer, and easier to organize.

Why it exists

DuctCount began as a working tool for measuring duct runs, counting fittings and accessories, separating work by room or area, and producing useful takeoff lists from PDF drawings. It continues to grow through real job-site and estimating use.

Designed around actual work

The goal is straightforward: keep the drawing, measurements, counts, notes, saved projects, and pricing workflow connected without forcing users into complicated estimating software.
