So I need this “Manual J” Report – What does a Manual-J Load Calculation report really tell me?

An ACCA Compliant Manual J load analysis provides:
  • Individual Room x Room heating and cooling needs.
    • This is required by most permit offices and block loads are generally rejected
    • Helps determine your loads for each zone If you are installing multiple thermostats to independently control different areas of the house
    • Determines the needed airflow needed for each room (Manual T Air Distribution)
    • Determines the needed register and supply/return sizes (Manual D Duct Design)

  • How much heating does my home need for my family to be comfortable?
    • What is the heating load needed on almost the coldest night of the winter?
    • This is the load that the heating equipment sizing is based on
    • How much cooling does my home need for my family to be comfortable?
      • There are two parts to the cooling load
        • The Sensible Cooling Load is what a thermometer measures
          • What is the cooling load needed on almost the hottest day of the summer?
      • The Latent Cooling Load is the humidity present
        • What is the worse-case condition (most humid and hot summer day)?
  • This is the combined sensible and latent load that the cooling equipment sizing is based on.
