HVAC Stages
NOTE: Depending on your HVAC equipment, the number of stages and their exact meanings may vary. Your system may not have all of the stages below, or you may have additional ones not specifically listed. Your HVAC dealer can provide additional information regarding your specific equipment.
We highly recommend that you enable Trane® Diagnostics to allow your dealer to see information about your HVAC system performance.
COOLING |

| Stage 1 Cooling | Cooling in single-stage systems or first-stage cooling in multiple-stage systems. |
