What It Means
High Refrigerant Pressure
Likely Causes
- Dirty evaporator coil reducing airflow
- Low water flow rate through heat exchanger
- Refrigerant overcharge
Next Checks
- Clean evaporator coil fins thoroughly
- Verify water flow rate — minimum 20 GPM typically required through heat pump
- Check that water-side unions on heat pump are fully open
- If coil is clean and flow is confirmed: refrigerant overcharge or other sealed-system issue, call HVAC tech
