Why is the supply air cold in my SystemAir Heating System?
- AAllison BurnettAug 9, 2025
If the supply air from your SystemAir Heating System is too cold, there are several things you can check: * Verify the set supply air temperature on the control panel. * Check the fire thermostat and reset it by pressing the red button if necessary. * See if the extract filter needs replacing. * Ensure the heat exchanger is rotating.
