> 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
