Infinity 80% Ultra-Low NOx (SCAQMD/SJVAPCD Compliant) Multipoise Gas Furnace, Variable Speed, 115/1

The 58CU0B delivers home comfort in an 80% AFUE furnace that meets the nitrogen oxides (NOx) emission limit of 14 nanograms/joule for South Coast Air Quality Management District, San Joaquin Valley Air Pollution Control District in California, and Bay Area Air Quality Management District. It provides warm winter heating with 65% lower NOx emissions than standard models.

The Infinity® 80 Ultra Low NOx Gas Furnaces offers a number of comfort-enhancing features with its constant airflow variable-speed Infinity ECM blower motor. ComfortFan™ technology selectable fan speeds allows control over ventilation. SmartEvap™ technology provides humidity control during cooling operation, and with select outdoor units, Ideal Humidity System™ technology provides significantly better dehumidification. And, when paired with a two-speed or variable-speed outdoor unit, homeowners will enjoy consistent summer comfort.
