“Wait,” you’re saying, “what’s a packaged HVAC unit? Is that like a window AC?”
Well, sort of. A packaged HVAC unit is a cooling system or heat pump where all the components are contained in a single cabinet. The compressor, the evaporator coil, the condensing coil, the fans and motors—the works. The opposite of a packaged unit is a split system or a mini split system, where there are separate indoor and outdoor units. For example, the most common type of central AC found in homes is a split system with an outdoor condenser and an indoor evaporator with an air handler that sends the cooled air into the ducts.
