HVAC without ductwork is like ice cream without a freezer: It just doesn’t work. Ductwork is a mandatory comfort delivery system. In fact, the only thing optional about it is whether or not HVAC contractors make their own fittings and duct runs. That piece of the ventilation machine is left not to chance, but to choice. A choice made by every contractor in the industry: “Should we fabricate ductwork and fittings in-house, or should we have someone else make what we need?”
