Platinum Choice – 97% Efficient Full-Modulating Furnace
This is the PREMIER furnace offered by Armstrong Air. This furnace provides superior comfort over single stage or two stage furnaces, giving you reduced temperature swings throughout your home along with being more than 97% efficient – the highest efficiency you can currently get in a furnace. It comes with a variable speed fan motor which can change the start-up airflow. Changing the airflow during start-up can adjust humidity levels and create more even temperatures throughout your home. The 97 Modulating Furnace also was rated Energy Star® Most Efficient for 2013. The modulating heating system works with a variable-speed fan motor to make your indoor climate as comfortable as can be. As temperatures outside change from hour to hour, the system automatically varies heating output to ensure a consistent, quiet flow of warm air throughout your home. Most of the time, the A97MV runs at a lower speed, so you can enjoy optimal comfort with less energy waste and greater savings.
Gold Standard – 96% Efficient Two-Stage Furnace
96% of your fuel is converted into usable heat. Rather than “all on” or “all off” this two-stage furnace can adjust its heat output based on the conditions inside your home so you use less energy to maintain comfort. It contains a variable-speed blower, which allows the furnace to adjust humidity levels and create more even temperatures throughout your home, while also enhancing efficiency and reducing operating noise.
Silver Option – 95% Efficient Constant-Torque Furnace
This furnace provides lower operating costs and increases overall system efficiency over an existing or older furnace. Compared to standard furnaces, constant torque delivers more consistent airflow and quieter operation. The constant torque motor on the A951E provides an efficient, steady flow of air for more even temperatures. This Energy Star-certified furnace offers single-stage heating, allowing it to run at lower output most of the time, then ramp up to a higher output when needed.
Bronze Basic – 95% Efficient Furnace
This furnace is a single stage unit that has a 95% rating in efficiency. It is made with a stainless-steel heat exchanger. This can save you hundreds per year in energy costs versus an older furnace. The 95% AFUE of these units combined with our patented EHX™ and Quiet Combustion™ technology lets you enjoy lower utility bills without lowering your standard of comfort. The A951A and A951S deliver the warmth and efficiency you need all winter long.
