An HVAC system is provided for use in a vehicle having a passenger compartment volume. The HVAC system includes a HVAC housing having a duct opening formed in an exterior sidewall thereof. An evaporator is further provided for exhausting air downstream that is cooler than the air on the upstream side. An auxiliary compartment, such as a storage bin, is spaced apart from the HVAC housing, such as in a remote location of the passenger compartment. An auxiliary duct fluidly interconnects the HVAC housing and the auxiliary compartment via the duct opening for transmitting the cool exhausted air to the auxiliary compartment to provide a cooling effect within the auxiliary location. The auxiliary duct, in some embodiments, is disposed external from the HVAC housing for improved service and retrofitting to existing HVAC systems.
