Rather than being “all on” or “all off,” your furnace can adjust its heat output based on conditions inside and outside your home. So you use less energy to maintain comfort.

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.

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

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

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.

Your Armstrong Air furnace’s electronic control system prolongs system life by continuously monitoring internal components for optimum performance and fault prevention.

Armstrong Air's commitment to a better product is backed by a Limited Lifetime Warranty on the aluminized steel heat exchanger and a 10-Year Limited Warranty on parts.
