Armstrong Air Gas Furnace, 1-Stage, Series: A801E, 70000 Btu/hr Input, 53000 Btu/hr Output, 120 V, 80 % AFUE, Upflow/Horizontal Furnace Position, No Low NOX, High Efficiency Constant Torque Blower Motor, 1/2 hp Motor, 1/2 in, Silicon Nitride Ignition, 15 A Fuse, Aluminized Steel, 14-1/2 in W x 28-3/8 in D x 33 in H
80% AFUE efficiency rating - compared to an older furnace, this can potentially save you hundreds of dollars per year in energy costs
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
