A multi-zone heat exchanger has a first end and a second end and a width divided into a plurality of parallel airflow zones. Each zone defines an airflow section of the heat exchanger that receives a portion of the airflow through the heat exchanger. A first tube of continuous construction is coupled to an inlet port and to an outlet port and forms a first refrigerant circuit spanning three or more passes from the first end to the second end. The first refrigerant circuit passes between at least two zones of the plurality of zones. A second tube of continuous construction is coupled to the inlet port and to the outlet port and forms a second refrigerant circuit spanning three or more passes from the first end to the second end. The second refrigerant circuit passes between the at least two zones of the plurality of zones.
