Aire-Flo once promoted its now-discontinued AF90MPE gas furnace series as a great value in the coldest of climates, with an AFUE of up to 92.1 percent. This furnace can be installed in upflow/horizontal-left or counterflow/horizontal-right configurations. The unit has a 3-speed blower motor.
For added durability, the heat exchanger has Crimp-Tite seams, while the cabinet is made corrosion-resistant by its heavy-gauge, pre-painted coating. The whisper-quiet burners and Honeywell slow-opening Smart Valves are designed for quiet operation. Furthermore, the Honeywell “Smart Valve” system has LED diagnostics that make troubleshooting simple.
For safety, a 5-amp fused low voltage circuit protector helps earn this gas furnace ANSI and CSA certifications. Connections for an electronic air cleaner, humidifier and continuous fan add-ons are standard, and all Aire-Flo gas furnaces can use a common LP kit.
