The Two-stage, Variable-speed, 4-way Multipoise Gas Furnace offers outstanding comfort in an 80% AFUE furnace.
You get the benefits of Perfect Heat™: reduced drafts, reduced sound levels, longer cycles, less temperature swings between cycles, less temperature differences between rooms, and improved indoor air quality. Plus, it features a dehumidify mode and the ability to change continuous fan speeds from the thermostat. The 820TA/821TA furnaces are approved for use with natural or propane gas. 821TA - Low NOx units are designed for California installations and meet 40 ng/J NOx emissions. Can be installed in air quality management districts with a 40 ng/J NOx emissions requirement.
