Manual J / S / D HVAC Design FAQs
What is a Manual J HVAC load calculation?
A Manual J calculation determines the heating and cooling load of a home based on square footage, insulation, layout, and climate zone. It’s the foundation of residential HVAC design and ensures the system is sized correctly for comfort, efficiency, and IECC compliance.
Why do I need a Manual S equipment selection report?
Manual S is used to match properly sized equipment to the load calculated in Manual J. It confirms the HVAC system’s capacity, airflow, and performance align with the project requirements and energy code.
What is Manual D duct design?
Manual D specifies the design and sizing of the home’s duct system. It ensures airflow is balanced, static pressure is correct, and the HVAC equipment performs as intended once installed.
Are Manual J, S, and D required for permits?
Yes. Most jurisdictions require Manual J, S, and D reports for mechanical permits under 2021 IECC and newer. These reports verify that the HVAC system meets energy code requirements.
Do you offer nationwide HVAC design services?
Yes. Our partners at Scott Home Services provide fully online, nationwide HVAC design services, including Manual J/S/D report preparation, with turnaround times from 2–7 days.
