Carrier has improved its Performance Series fan coils for easier installation and a nearly 20 percent smaller footprint. The enhanced coils offer factory-installed electric heat options, as well as increased flexibility for single-stage-demand dehumidification. The units are available in two options: a 2-ton 15 seasonal energy-efficiency rating with a 14-inch-wide cabinet and a 5-ton 15 SEER rating with a 21-inch-wide cabinet. The coils achieve a wider airflow range and include a lower continuous fan option, resulting in lower electric bills and lower sound levels.
