About Therm Sched

What this tool does

HVAC tools size air conditioners for room dimensions, calculate duct sizes for airflow, determine air changes per hour, estimate heat loss through walls, apply fan laws for system design, and size expansion tanks.

Why use this tool

An undersized AC struggles in summer heat; an oversized unit short-cycles and dehumidifies poorly. Correct sizing from the start saves energy costs and improves comfort. These calculators apply Manual J and industry-standard formulas.

How it works

Room BTU estimates use floor area, ceiling height, insulation R-value, window count, climate zone, and occupancy. Duct sizing applies the equal-friction method to balance pressure drop and noise. Fan laws scale performance using cube and square relationships.

Pro tip

When sizing an AC unit, do not just calculate the cooling load. Factor in local humidity. In humid climates, you may need to slightly undersize the unit so it runs longer cycles and removes more moisture.
