HVAC FORMULATOR is the essential tool for Heating, Ventilating, and Air
Conditioning professionals. With over 900 formulas and calculations, it covers
everything from basic load calculations to advanced system design — all in
your pocket.
US & METRIC SUPPORT — Switch instantly between US (Imperial) and Metric (SI)
units. Results display in both systems so you always have the value you need.
Input labels and conversions update automatically.
