HVAC Builder provides a web‑based platform to design, solve, and simulate custom HVAC systems. Users can build 3‑D models, run thermodynamic calculations, and simulate a full year of operation against real weather data. The service offers a free tier and paid plans with additional compute tokens, saved projects, and advanced features. It targets engineers, architects, and building managers seeking accessible HVAC analysis without installing desktop software.
