95% AFUE Efficiency Rating - This means 95% 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 costs

Constant Torque Motor - Like a variable speed furnace, constant torque furnaces provide lower operating costs and increases to overall system efficiency Compared to standard PSC motors, constant torque delivers more consistent airflow and quieter operation

Dual-Fuel Compatible - The combination of a gas furnace and an electric heat pump pairs two energy sources for the perfect balance of energy efficiency and comfort

Quiet Combustion Technology - Uses a smaller Btu input per burner for quieter start-up and operation while providing more even heat distribution

Advanced Heat Exchanger - Made from stainless steel for maximum strength and crimped, rather than welded, Armstrong Air heat exchangers are highly resistant to thermal fatigue and other stresses caused by repeated heating and cooling. During the testing process they are subjected to temperatures that far exceed normal operating ranges to ensure they will stand up to years of use

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

Internal Monitoring - Your Armstrong Air furnace's electronic control system prolongs system life by continuously monitoring internal components for optimum performance and fault prevention

Up to 15 SEER Efficiency Rating-SEER (Seasonal Energy Efficiency Ratio) rates the energy efficiency of your cooling equipment. The higher the SEER rating, the more efficiently your unit operates, saving you money on utility bills

Up to 8.5 HSPF Efficiency Rating-HSPF (Heating Seasonal performance Factor) rates the energy efficiency of your heat pump. The higher the HSPF rating, the more efficiently your unit operates, saving you money on utility bills

Heavy Duty Compressor Blanket-Greatly reduces operating sound so your outdoor entertaining is not interrupted

Quiet Shift Technology-Allows heat pumps to enter defrost mode without excessive noise

Since refrigerant pressure is allowed to equalize before the switch, the heat pump can dissipate performance-robbing frost and ice quietly

MHT Technology-Armstrong Air's proprietary heat transfer system

A specially designed fan shroud pulls air evenly throughout the air conditioner's coil surface

The coil features rifled tubing to enhance refrigerant flow, while lanced coil fins increase surface contact between metal and air

All combine for maximum heat transfer and efficiency
