Load Calculations (HVAC Sizing) Kansas City | Central Energy Audits

Kansas City Load Calculations (HVAC Sizing) ensure your heating and cooling systems are neither oversized nor undersized — saving you money, improving comfort, and helping you meet energy code compliance. At Central Energy Audits, we deliver precise Manual J, S, and D load calculations for residential new construction and renovation projects throughout the Kansas City area.

​

 

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.

  • Homeowners building or upgrading HVAC systems
     

  • Builders and contractors needing permit approval
