5 Ton Gas Furnace, Upflow/Horizontal, Heat Exchanger, Variable Speed, 110,000 BTU

Armstrong Air A97MV – 97% AFUE Modulating Gas Furnace with Variable Speed Blower

The Armstrong Air A97MV high-efficiency gas furnace is engineered to deliver precise temperature control and maximum energy savings. With a 97% AFUE rating, this furnace ensures that nearly all the fuel consumed is converted into usable heat, reducing waste and lowering annual heating costs. Its modulating gas valve and variable-speed ECM blower motor provide consistent comfort by adjusting output to meet demand.

Constructed with a stainless steel primary heat exchanger, the A97MV offers enhanced corrosion resistance and long-term durability. The cabinet is fully insulated to reduce air leakage and minimize operational noise, making it suitable for residential installations requiring both performance and quiet operation.
