So, 1.5-ton, 2-ton, 2.5-ton, and so onThe duct for this system must be sized by using 6 square inches of clear duct area for each 1000 BTU of cooling. Each ton of cooling contains 12,000 BTU. Multiply the tonnage, 3.5, by the total BTU per ton and this will give you the total BTU rating. 3.5 x 12000 = 42000.
