> User: "AHU not cooling properly"
ASHRAE 90.1
⚠️ Possible Causes:
  • Dirty or clogged pre/HEPA filter media
  • Low chilled water (CHW) flow or closed 2-way valve
  • Thermostat calibration / sensor offset error
🔍 Checks:
  • Check filter differential pressure (DP > 150 Pa indicates dirty)
  • Check CHW supply temperature (design 7°C / 44.6°F)
🛠️ Corrective Action:
  • Clean/replace pre-filters; inspect coil face velocity
  • Restore design chilled water flow rate via balancing valve
