At the heart of every Armstrong Air furnace, you’ll find a marvel of durability and comfort known as an Armstrong Air heat exchanger with EHX Technology. Each one is built to last and built to outperform every previous heat exchanger we’ve ever made. 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. Furthermore, they are subjected to extensive torture testing to ensure they’ll outperform your expectations, season after season.

The burners inside every Armstrong Air furnace aren’t like the burners you’ll find in other furnaces.

No detail was overlooked in their design, from their deeper, specially shaped fuel channels to the increased number of jets. As a result, Armstrong Air furnaces operate with extreme reliability,
impressive efficiency and very low noise levels.

Inside every Armstrong Air air conditioner and heat pump, you’ll find a brilliant approach to cooling called MHT Technology.

Armstrong Air’s proprietary heat transfer system, a specially designed fan shroud pulls air evenly throughout the air conditioner’s coil surface. The coil features rifled tubing to enhance refrigerant flow, while lanced coil fins increase surface contact between metal and air. All combine for maximum heat transfer and efficiency.

Allows heat pumps to enter defrost mode without excessive noise. Since refrigerant pressure is allowed to equalize before the switch, the heat pump can dissipate performance-robbing frost and ice quietly.
