AN automatic climate control air-conditioning system is standard on the 156.

Alfa claims the system was specially finetuned to create a "climate" rather than a "fan" effect. The unit features a two-stage air filtering system designed to remove pollutants and pollens. A four-speed centrifugal fan produces an airflow unaffected by the speed of the car. Air-conditioner coolant is retrieved for re-utilisation in "cascade" fashion. Bi-level airflow directs warm air towards the floor and cooler air from the facia vents.
