AC Cooling Load Calculator (BTU) — Free Manual J Lite
How many square feet does a 2-ton AC cool?
A 2-ton (24,000 BTU/hr) unit typically cools roughly 900–1,300 sq ft in a moderate climate with average insulation. The range is wide because ceiling height, window area, sun exposure, and air-sealing all shift the load — use it as a sanity check against a Manual J result, not as the basis for selecting equipment.
