Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| System not cooling/heating | Power loss, thermostat issue, capacitor failure | Check circuit breakers, verify thermostat settings, test capacitors |
| Insufficient cooling/heating | Low refrigerant, dirty coils, restricted airflow | Check refrigerant charge, clean coils, check filters and ductwork |
| Frequent cycling | Oversized unit, thermostat location, dirty filter | Verify proper sizing, relocate thermostat, replace air filter |
| High energy bills | Dirty coils, low refrigerant, duct leaks | Clean coils, check charge, seal ductwork |
| Unusual noises | Loose parts, failing motor, refrigerant issues | Tighten components, check bearings, verify proper operation |
| Water leaks | Clogged drain line, improper slope, pump failure | Clear drain line, ensure proper slope, check condensate pump |
| Ice formation | Low airflow, low refrigerant, defrost issues | Check filters and blower, verify charge, test defrost components |
