The Affinity furnace, which offers 95 percent annual fuel utilization efficiency (AFUE), is said to maintain a constant temperature while delivering improved comfort, quieter operation, and reduced energy costs. By varying (modulating) the gas input and the circulating airflow to closely match the amount of heat needed at any given time, the furnace is designed to deliver maximum performance, comfort, and savings, while minimizing the sound level in the home.

With the new sizes of the Sunline MagnaDRY reheat series, it is now available in nine different sizes, ranging from 3 to 25 tons (3, 4, 5, 6, 7.5, 10, 15, 20 and 25). The MagnaDRY reheat series packaged units remove moisture and use a reheat mode of operation that doesn't rely on electricity or natural gas. The units combine a high-efficiency single-package heating and cooling unit with an advanced dehumidification system that allows maximum dehumidification independent of the cooling load.
