What Are HVAC Load Calculations?

Load calculations analyze a home’s thermal envelope and mechanical systems to determine the proper size and configuration for HVAC equipment. We follow ACCA-approved Manual J, Manual S, and Manual D protocols to evaluate:

  • Heating and cooling demands (Manual J)
     

  • Equipment selection and sizing (Manual S)
     

  • Duct design and layout (Manual D)
     

Proper sizing prevents overspending on oversized units and ensures maximum system efficiency and indoor comfort.
