Keep the outdoor condenser unit free from debris such as leaves, dirt, and grass clippings. Ensure the coils are clean for optimal heat exchange. The system features a self-cleaning function to help maintain coil cleanliness.
5.3 Professional Inspection
Schedule annual inspections and maintenance with a qualified HVAC technician. They can check refrigerant levels, electrical connections, and overall system performance.
6. Troubleshooting
Before contacting customer support, review the following common issues and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| System not turning on | No power, thermostat settings incorrect, safety switch tripped. | Check circuit breaker, ensure disconnect switch is ON, verify thermostat settings. |
| Insufficient heating/cooling | Dirty air filter, blocked outdoor unit, low refrigerant, incorrect thermostat setting. | Clean/replace air filter, clear debris from outdoor unit, check thermostat. Contact technician for refrigerant issues. |
| Unusual noises | Loose parts, fan obstruction, compressor issue. | Inspect for loose panels or debris. If noise persists, contact a qualified technician. |
| Water leakage | Clogged condensate drain line, improper installation. | Check and clear condensate drain. If issue persists, contact a qualified technician. |
For issues not listed here or if troubleshooting steps do not resolve the problem, contact a qualified HVAC technician or ACiQ customer support.
