Residential Air Conditioning and Heating Load Calculations

manual j load calculation

Before you have your air conditioning and heating system replaced insist on having the installing company perform an accurate ”Manuel J Load” calculation on your home. An accurate load calculation will require…

  1. Localized outdoor design conditions.
  2. Personalized indoor design conditions.
  3. Building infiltration estimates.
  4. Solar Loads associated with glass.
  5. Duct loss and gain calculation.
  6. Conduction loads.
  7. Ventilation loads.
  8. Internal loads

It is not possible to correctly size an HVAC system without completing a Manuel J load calculation. Contractors who proceed without this important step put their clients at risk of having to live with over sized and/or undersized equipment and the resulting expenses and discomfort.
