ARMSTRONG AIR A97USMV070B12S - 1.5-3 Ton 66 MBH 97% Mod Furnace Variable Speed ECM Motor (A97USMV070B12S)

• Modulating Heat

Provides superior comfort over traditional single- stage and two-stage products, further reducing temperature swings in your home.

• ENERGY STAR® Most Efficient 2020

ENERGY STAR Most Efficient is a new program that identifies the most efficient products among those that qualify for the ENERGY STAR. Each product that receives this recognition demonstrates efficiency performance that is truly exceptional, inspirational, and leading edge.

• Variable Speed Fan Motor

By changing the speed of its airflow during start-up, your furnace can adjust humidity levels and create more even temperatures throughout your home, while enhancing efficiency and reducing operating noise.

• 97% AFUE Efficiency Rating

This means 97% 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.

• 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.
