Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| System won't start | Power issue, thermostat setting, safety lockout | Check circuit breaker, thermostat settings, reset system |
| Insufficient cooling/heating | Dirty filters, low refrigerant, blocked airflow | Clean/replace filters, check refrigerant charge, clear obstructions |
| System cycles on/off frequently | Dirty coils, incorrect charge, oversized unit | Clean coils, check refrigerant charge, verify proper sizing |
| Water leakage | Clogged drain line, improper slope, frozen coil | Clear drain line, ensure proper slope, check for ice formation |
| Unusual noises | Loose parts, failing motor, refrigerant issues | Tighten mounting hardware, check motors, verify refrigerant flow |
| High energy consumption | Dirty components, refrigerant issues, duct leaks | Clean system components, check charge, seal ductwork |
| Ice formation on coils | Low airflow, low refrigerant, dirty filters | Check airflow, verify charge, clean/replace filters |
