Terms

These pages are planning tools. They are not professional engineering, not a permit document, and not a substitute for ACCA Manual J, Manual S, or Manual D. They are not a contractor quote and not an offer to sell or install equipment.

You are responsible for hiring a licensed contractor and for any equipment purchase. Wrong tonnage is expensive to undo. Florida code and many manufacturer warranties expect a proper load calculation.

The calculators are provided as-is, with no warranty of accuracy, fitness, or availability. Window area, glass type, attic R-value, duct leaks, occupancy, and kitchen heat can move a real load a half-ton or more.

Governing law: Florida, United States.
