What a Manual J calculation covers

A Manual J calculation estimates the heating and cooling loads for a residential project using the project information and plans you provide. Depending on the project and order, the report can include room-by-room and/or block load results.

Heating load calculations for the home and, when included in the order, individual rooms.

Cooling load calculations for the home and, when included in the order, individual rooms.

Results based on supplied details such as the floor plan, project location, areas, windows, doors, insulation, and other available building information.
A PDF report delivered by email, with hard copies mailed on request.

Manual J is the load-calculation step. Manual S equipment selection and Manual D duct sizing are separate deliverables and are not included unless ordered separately.

What Information Is Needed?

Start with your floor plans, project address, approximate square footage, and the services you want. Elevations and the following details help us refine the calculation: floor plans with room dimensions and layout; elevations and site orientation, if available; insulation R-values and construction details; window U-factor and SHGC, when available; doors, skylights, and other envelope details; planned HVAC equipment and system zones; and occupancy information when relevant to the project. Do not have every detail? Send what you have. We will identify missing information before the report is prepared.

Room-by-Room or Block Loads

A room-by-room load assigns heating and cooling loads to individual rooms, which can help the installing contractor evaluate distribution and equipment needs. A block load treats the home as one combined load. Manual J Express can quote either scope when available for the project. Room-by-room output is not included automatically in every order. Your quote will identify the requested scope.

What Does the PDF Report Support?

Your Manual J PDF is a design-support report for HVAC planning and may support a permit submission when it matches your local building department’s requirements. It is not an engineering seal or a complete set of construction drawings, and it does not guarantee permit approval. The installing contractor verifies site conditions and makes the final equipment selection.

Manual J, Manual S, and Manual D Are Separate Deliverables

Manual J calculates the home’s heating and cooling loads. Manual S selects equipment from manufacturer data. Manual D addresses duct sizing and layout. A Manual J order does not automatically include Manual S or Manual D.
