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.
This means 96% 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.
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 ENERGY STAR program is a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy helping us all save money and protect the environment through energy-efficient products and practices.
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.
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.
