The 59SU5B Comfort™ 95 Ultra-Low NOx gas furnace delivers consumer comfort in a unit that meets California’s South Coast Air Quality Management District (SCAQMD) and San Joaquin Valley Air pollution Control District (SJVAPCD) NOx emissions limit of 14ng/J. Offering the performance and benefits of our Comfort Series gas furnaces, this furnace releases 65% less nitrogen oxides (NOx) than previous models. NOx contributes to the formation of smog and acid rain and the deterioration of water quality. Lower NOx emissions mean lower production of particulate matter and cleaner air for the environment. Energy efficiency is at the heart of this furnace with up to 95.0% AFUE gas efficiency and the electrically-efficient fixed-speeds, constant torque (MCT) ECM blower motor. Improved serviceability with the 3 digit status display and NFC enabled board allowing setup via the service tech app. This gas furnace also features Upflow/Horizontal installation flexibility, and is available in four model sizes. All sizes can be vented for direct vent/two-pipe, ventilated combustion air, or single-pipe applications.
