Excellent HVAC Tool for On-Site Use
I’m really impressed with HVAC Calc – Duct & Airflow—a true field-ready app for engineers and technicians. The duct sizing tool is spot-on: just input your airflow and velocity, and it instantly gives you both circular and rectangular dimensions. The airflow and friction loss calculators (using Darcy-Weisbach formula) are fast and accurate—even if you’re working completely offline on the job site. Love the PDF report generator for sharing neat, professional summaries. Compact, reliable, and highly recommended for anyone needing quick HVAC calculations.
