Important: This calculator provides a preliminary estimate and should not be used as a substitute for a professional HVAC load calculation. Actual equipment sizing can depend on insulation, windows, orientation, ductwork, air leakage, local climate, building construction and other factors. A professional Manual J load calculation is recommended before selecting equipment.
