Use these tools for practical planning, checking, and early-stage engineering support. Each tool includes sample data, calculation results, interpretation, warnings, assumptions, confidence notes, and branded print output.
How to use this page
HVAC tools cover cooling load, airflow, duct velocity, chilled water pipe sizing, and exhaust fan estimates. They help engineers and contractors check assumptions quickly before detailed modeling or equipment selection. Final design should account for climate data, diversity, controls, noise limits, pressure losses, and project specifications.
