HVAC FORMULATOR is the perfect tool for any Heating Ventilating and Air Conditioning Professional. This program contains nearly 200 formulas helpful HVAC Professionals. Sections include: Air Change, Airside, Boilers, BTU Conversions, Ductwork, Energy Values, Heating Design, Heating Requirements, Humidity, Loads, Pumps, Steam, Temperature, Waterside Systems, Conversions and Area Calculations. Heating design calculations include formulas such as: electric heating calculations, electric baseboard, Heat Tracing Cable, Gas Fired Radiant Ceiling formulas. HVAC FORMULATOR provides an easy was to quickly find what you need, you can search, mark formulas as favorites, or access recently used formulas.

HVAC FORMULATOR is the third version of a dynamic program, planned to develop and evolve. It was not our intent to include every possible HVAC formula in this program version. Additional formulas will be added over time. If there is a formula you would like us to add, please contact us and we will do our best to add that formula.
