Common Issues
| Problem | Possible Cause | Solution |
|---|---|---|
| System not cooling | Low refrigerant, dirty coils, compressor failure | Check refrigerant charge, clean coils, test compressor operation |
| High energy consumption | Dirty filters, improper charge, duct leaks | Replace filters, verify refrigerant charge, seal ductwork |
| Short cycling | Oversized unit, dirty filter, thermostat issues | Verify proper sizing, clean/replace filter, calibrate thermostat |
| Water leakage | Clogged drain line, improper slope, pump failure | Clear drain line, ensure proper slope, check condensate pump |
| Unusual noises | Loose components, failing bearings, refrigerant issues | Tighten all fasteners, replace motor bearings, check refrigerant flow |
| Ice formation on coils | Low airflow, low refrigerant, dirty evaporator | Check filters and blower, verify charge, clean evaporator coil |
