What is Manual J, and Manual S

Manual J is the protocol used for determining the amount of heating and cooling that a home requires to keep its occupants warm in the heating months and cool and dry in the cooling months.

Manual S is used to size and select the heating and cooling equipment. The goal for equipment selection is to install heating and cooling systems with the same heating and cooling capacities as the heating and cooling loads of your home.

Below are the accepted approved software programs. For more information, visit ACCA.
