With two different cooling output speeds, these exceptional performers  offer the ideal balance between smart energy use and serious comfort. 


Single-Stage Performance

 Enjoy consistent, reliable cooling and a home full of refreshing air. 

Comfort Sync Thermostat

Enjoy sophisticated system management, unprecedented control and exceptional energy savings with a Comfort Sync thermostat. It’s the best way to get the most out of every part of your Armstrong Air system. 

Armstrong Air Warranty

Every piece of heating equipment is eligible for a 10-Year Parts  Warranty and Limited Lifetime Heat Exchanger Warranty.  All other  products are eligible for the 10-Year Parts Warranty as well. All  products will need to be registered on our website within 60 days of  purchase or the warranty will default to a 5-Year Limited Warranty on  parts and a 20-Year Limited Warranty on the heat exchanger. 

Energy Savings

  • Heating Efficiency: 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 furnances go all the way up to 97%.  That means 97 cents of every dollar goes to efficient heating. HSPF stands for Heating Seasonal Performance Factor and is a measurement of a heat pump's heating efficiency.  There is no governmental minimum efficiency level for HSPF. 


  • Cooling Efficiency: SEER stands for Seasonal Energy Efficiency Ratio and is a measurement of the  efficiency of cooling products.  The U.S. government’s minimum efficiency level is 13.0, but Armstrong Air cooling products exceed 18.0 SEER.
