Armstrong Air’s EHX Technology Eliminates Hot Spots that Shorten Furnace Life

Every Armstrong Air® furnace is built with EHX™ Technology, a patented design that eliminates the hot spots that can shorten furnace life. 

Heat exchangers with EHX Technology are held together via crimping rather than welding, to reduce fatigue from heat strain and improve durability. They are specially shaped to improve airflow, contact and heat transfer for added warmth. And, they are subjected to extensive torture testing prior to leaving the factory to ensure they’ll outperform your expectations, season after season.  Take a look for yourself
