Two-stage Technology

Affinity 8.T and 9.T High-Efficiency Gas Furnaces
Affinity T series furnaces use two different heating levels to improve their performance. They operate on low stage to save energy up to 85% of the time. The second stage only operates when the weather turns bitterly cold. In addition, Affinity T series models run for longer periods of time at lower fan speeds. This produces fewer temperature swings, better air circulation, improved Indoor Air Quality, and less noise from starts and stops.
