  Robin DayAug 8, 2025
  If you notice reduced airflow in your SystemAir Fan, there are several things you can check. Start by checking the airflow setting on the control panel. Also, see if the filter needs changing or cleaning. Check if the diffusers or louvers require cleaning. Furthermore, inspect the fans and exchanger block for any need of cleaning. Ensure the roof unit or air intake isn't clogged. Inspect visible duct runs for damage or buildup of dust or pollution. Finally, check the diffuser and louver openings.

Why is the supply air from my SystemAir Fan cold?
- R
  rlewisAug 14, 2025
  If the supply air from your SystemAir Fan is too cold, check the set supply air temperature on the control panel. Also, check if the fire thermostat(s) is(are) still alert and reset it if necessary by pressing the red button "H" in the unit. Another cause could be that the extract filter needs cleaning. If there is ice in the exchanger block, stop the unit and let the ice melt. Contact your service representative if this happens repeatedly. Finally, check if a summerblock is installed in the unit.
