DuctSizer Pro vs UnitNote

DuctSizer Pro is a fast HVAC duct sizing calculator built for field use. Enter duct dimensions and friction to calculate CFM, or enter CFM and friction to find suggested duct sizes. The app supports square, round, and oval ductwork and shows key airflow values such as velocity, friction, area, and equivalent round size. Features: - Calculate CFM from duct size - Find duct sizes from CFM - Supports square, round, and oval duct - Shows velocity, friction, area, and equivalent round size - Highlights suggested duct sizes - Compares alternate duct sizes for the same airflow DuctSizer Pro is designed as a quick reference tool for HVAC layout, estimating, and field calculations.
