Use Square Feet per Ton to calculate system size.
Formula:
Home Size (sqft) ÷ Square Feet per Ton = Estimated Tonnage
Example: 2000 sqft ÷ 500 sqft/ton = 4-ton system
Customize this value based on your region and climate.
Uses BTU per Square Foot, and distinguishes between gas and electric systems.
Formula:
Home Size (sqft) × BTU per Square Foot = Estimated BTUs
Example: 2000 sqft × 50 BTU/sqft = 100,000 BTUs
Again, adjust values based on your service area.
