5. Energy Efficiency & Cost Savings

1. Calculate Your Savings – Use the formula:

[[

text{Annual Savings (IDR)} = (text{Power Consumption (kWh)}{text{standard}} – text{power Consumption (kWh)}{text{inverter}}) times text{Electricity Rate}

]

• Standard 9,000 BTU fixed‑speed: ~210 kWh/year.
• Inverter mini AC (avg.): ~150 kWh/year.
• average Indonesian residential rate (2025): 1,500 IDR/kWh.

Result: Roughly 90,000 IDR saved per year per unit.

2. EER as a Buying Metric – Higher EER = better performance per watt. Models above 3.5 W/W are considered “high‑efficiency” in the Indonesian market.

3. eco‑Mode Impact – Engaging Eco‑Mode can lower consumption by an additional 5‑10 % during low‑load periods (nighttime or over‑cloudy days).

---

6. Installation & Space Considerations

• Vent Placement: for optimal airflow, install the exhaust vent at the highest point of the wall or window. A 10‑cm clearance from the wall ensures proper heat dissipation.
• clearance Requirements: Keep at least 20 cm behind the unit for air intake; avoid placing near heat‑producing appliances.
• Power Supply: All three units operate on a standard 220‑240 V single‑phase circuit. A dedicated 10 A breaker is recommended to prevent overload during turbo mode.

8. Practical Buying Tips

1. Check Energy Rating Labels – Look for the Indonesian “Label Energi” stamp showing the EER and annual electricity consumption.
2. Compare Warranty Coverage – Verify that the dealer offers on‑site service for the full 2‑year period; some e‑commerce platforms provide extended warranty packages at a marginal cost.
3. Assess Noise Levels in Real Settings – Request a demonstration in a showroom; the spec sheet may list ideal conditions, which differ from a typical bedroom.
4. Prioritise Smart Integration – If you already use a home automation hub (e.g., Google Home or Amazon Alexa), select a unit with native voice‑assistant support to streamline control.
5. Plan for Future Expansion – Choose a model that supports additional indoor units via a single outdoor condenser (few mini ACs now offer “multi‑zone” add‑on kits).
