Our free, easy-to-use HVAC load calculator will help you determine the necessary thermal output capacity (in BTUs) of any residential building.
The first in the series, Cooling and Heating Load Calculation Manual, by William Rudoy and Joseph Cuba, was published in 1980. A second edition, by Faye McQuiston and myself, was published in 1992 and focused on new developments in the transfer function method and the cooling load temperature difference method.

An HVAC load calculator, also known as a Manual J calculator, is a tool that helps determine the amount of heating and cooling power needed to keep a building comfortable. It considers factors like the size of the building, the number of windows, insulation levels, and other details to calculate the “load” or demand for heating and cooling.
Cooling & heating load calculations are normally made to size HVAC (heating, ventilating, and air-conditioning) systems and their components. In principle, the loads are calculated to maintain the indoor design conditions.
