A 1.5 ton air conditioner delivers 18,000 BTU/hr of cooling (5.28 kW thermal).
Electrical consumption depends on efficiency. A 1.5 ton 5-star inverter (ISEER 5.10) draws about 1,034 W; a 3-star unit draws roughly 1,388 W for the same cooling.
In US whole-home conditions, 1.5 tons covers roughly 720–1,000 sq ft depending on climate zone. As a single-room Indian split AC, it covers about 150–200 sq ft.
