Overview Of The Armstrong Furnace Brand
Armstrong Air has provided heating solutions for more than 90 years, focusing on residential and light commercial markets. Known for dependability, Armstrong furnaces are popular among HVAC professionals for their serviceability and long lifespan. The brand’s products are backed by Allied Air Enterprises, a Lennox International company, ensuring reliable customer support, parts availability, and warranty service across the United States.
Main Features Of Armstrong Furnaces
Armstrong furnaces offer a balance of efficiency, advanced technology, and practical features to suit diverse home needs.
High-Efficiency Ratings (AFUE)
AFUE (Annual Fuel Utilization Efficiency) ratings are a top consideration. Armstrong models range from 80% to 97% AFUE. High AFUE furnaces mean lower energy bills and reduced emissions. For cold regions, 95%+ AFUE models are ideal.
Variable-Speed And Two-Stage Burners
Many Armstrong furnaces feature variable-speed blower motors and two-stage burners. These technologies offer consistent heating, quieter operation, and better indoor comfort compared to single-stage models, which operate at full power or not at all.
Comfort Sync Thermostat Compatibility
Compatible models work seamlessly with the Comfort Sync thermostat, allowing advanced control, smart learning features, and remote adjustments through mobile devices.
Quiet Operation
Sound levels matter in modern homes. Armstrong integrates insulated blower compartments and variable motors to keep operation as quiet as possible, especially during low-stage heating cycles.
Durability And Build Quality
Armstrong’s units are constructed with rigid, insulated steel cabinets to prevent heat loss and corrosion. The brand uses high-quality heat exchangers designed to resist cracking and maximize service life.

Armstrong Air Furnace Technology Explained
Heat Exchanger Construction
Armstrong uses AL, 409L, and stainless steel proprietary heat exchangers in most units. These provide longevity, enhanced heat transfer, and lower risk of failure, a priority element for safety and warranty coverage.
ECM Motor Benefits
ECM (Electronically Commutated Motors) save on electricity bills, adapt blower speeds to heating demand, extend equipment lifespan, and minimize noise when compared to traditional PSC motors. They also aid in better filtration and improved air circulation.
Two-Stage, Modulating, And Single-Stage Heating
Two-stage and modulating models can adjust their heating output to match seasonal or daily needs. This results in stable indoor temperatures, less cycling, and savings in the long run. Single-stage models are best for budget-sensitive or smaller homes.
Armstrong Furnace Warranty And Lifespan
Armstrong offers competitive warranties for peace of mind:
- Limited lifetime warranty on heat exchangers for many models.
- 10-year limited parts warranty (registration required within 60 days of installation).
Properly maintained, Armstrong furnaces can last 15-20 years or more, often outlasting their warranty period. Annual maintenance by qualified HVAC professionals is strongly recommended to preserve warranty and extend operational life.
