WHY ARMSTRONG AIR?
Since 1928, Armstrong Air has been a smart choice for homeowners, and a constant recommendation from dealers. That’s because for nearly a century they have been at the forefront of emerging features and quality improvements in the HVAC industry.
AFUE stands for Annual Fuel Utilization Efficiency and is a percentage measurement of the furnace’s heating efficiency. The U.S. government's minimum efficiency level is 78% and the Canadian minimum is 90%, but Armstrong Air furnaces go all the way up to 97%. That means 97 cents of every dollar goes to efficient heating.
