dialecticeng.comModulating Cooling Capacity for HVAC Systems Direct-expansion (DX) HVAC equipment is still required to have the capability to stage or modulate cooling capacity. DX units with a capacity greater than 65,000 Btu/h (5.4 tons) that control the capacity of the unit based on space temperature, must have minimum of two (2) stages of cooling.
