Product DescriptionArmstrong Air 17A97 A931E 1-Stage Gas Furnace, Upflow/Horizontal, 90000 Btu/hr Input, 84000 Btu/hr Output, 120 V, 93 % AFUE, 1200 cfm Flow Rate, High Efficiency Constant Torque Blower Motor
Product Features
Applications: Residential
93% AFUE efficiency rating - this means 93% of your fuel is converted into usable heat, compared to an older furnace, this can potentially save you hundreds of dollars per year in energy cost
Constant torque motor - like a variable speed furnace, constant torque furnaces provide lower operating costs and increase overall system efficiency
Compared to standard PSC motors, constant torque delivers more consistent airflow and quieter operation
Quiet Combustion technology - uses a smaller btu input per burner for quieter start-up and operation while providing more even heat distribution
EHX technology - every Armstrong Air furnace is engineered and built with EHX technology, a patented design that eliminates the hot spots that can shorten furnace life
EHX technology makes heat exchangers more durable and with its advanced airflow system, more air contacts the heat exchanger surface area for greater heat exchange, enhancing efficiency and comfort
