Heat Pump Sizing Calculator
The Heat Pump Sizing Calculator is designed to estimate the appropriate capacity for a heat pump system, which provides both heating and cooling. Sizing a heat pump correctly is crucial for energy efficiency and comfort. This tool can use either a simplified area and climate factor method for a rough estimate, or inputs from a detailed Manual J load calculation (heating and cooling loads in BTU/hr). The calculator helps determine the necessary BTU/hr capacity, which is then often converted to Tons for equipment selection.
Heat Pump Types & Performance: Common heat pump types include air-source, geothermal (ground-source), and ductless mini-splits. Key performance factors are SEER (cooling efficiency), HSPF (heating efficiency), COP (instantaneous heating efficiency), and the balance point (outdoor temperature below which backup heat is needed). Understanding these helps in selecting an appropriately sized and efficient unit for your climate.

This tool provides a preliminary estimate. Heat pump sizing is complex and depends on specific equipment performance at various outdoor temperatures, balance points, and backup heating integration. Always consult a qualified HVAC professional using ACCA Manual S (equipment selection) based on Manual J (load calculation) for precise sizing.
