Singapore’s hot and humid climate makes air conditioning a necessity for many households. Among the various brands available, LG air conditioners are popular for their reliability, energy-saving features, and modern technology. But how much power does an LG aircon actually consume in a Singaporean setting? Let’s explore.
Factors Affecting LG Aircon Power Consumption
Below are a few factors that can affect the power consumption of LG aircon:
1. Type of LG Air Conditioner
- System 1, 2, 3, or 4: These refer to how many indoor units are connected to one outdoor compressor. The more units running, the higher the energy consumption.
- Inverter vs Non-inverter: Inverter models are more energy-efficient because they adjust compressor speed based on room temperature, instead of switching on/off like non-inverter types.
2. Cooling Capacity (BTU)
British Thermal Units (BTUs) determine how powerful the aircon is. A 9,000 BTU unit consumes less electricity than a 24,000 BTU unit. The right BTU for a room depends on room size, insulation, and sunlight exposure.
3. Energy Efficiency Rating (EER) & NEA Ticks
In Singapore, the National Environment Agency (NEA) provides energy labels with tick ratings (1 to 5 ticks). LG aircons with 4 or 5 ticks are more energy-efficient, leading to lower electricity bills.
4. Usage Patterns
- Hours of daily usage
- Thermostat setting (ideal range: 24–26°C)
- Frequency of maintenance
- Number of people in the room
Average Power Consumption of LG Aircons in Singapore
| Model Type | BTU | Wattage Range | Estimated Monthly Power Consumption (kWh) | Approximate Monthly Cost (SGD) |
| LG System 1 Inverter | 9,000 | 700–900 | 100–130 (8 hrs/day) | $25–$33 |
| LG System 2 Inverter | 9,000 x 2 | 1,400–1,800 | 200–260 | $50–$65 |
| LG System 3 Inverter | 9,000 x 3 | 2,000–2,700 | 300–390 | $75–$97 |
| LG System 4 Inverter | 9,000 x 4 | 2,700–3,600 | 400–520 | $100–$130 |
| LG Ceiling Cassette | 18,000+ | 1,800–3,000 | 300–500 | $75–$125 |
Note: Figures are approximate. Actual consumption depends on usage habits, insulation, and unit efficiency. Electricity cost estimated at $0.25/kWh based on SP Group rates.
Tips to Reduce LG Aircon Electricity Bills
- Use inverter models with at least 4 NEA ticks
- Clean filters monthly for smooth airflow
- Set temperature at 25°C for optimal comfort and savings
- Close windows and doors to prevent cool air from escaping
- Use a fan to distribute cool air more efficiently
- Schedule regular servicing to maintain efficiency
LG Features That Help Save Power
Below are a few features of LG aircon that help the AC save power usage.
- Dual Inverter Compressor™: Maintains temperature with less fluctuation, using less electricity
- SmartThinQ™ Technology: Control your aircon remotely to monitor usage and adjust temperature
- Auto Cleaning: Prevents dirt build-up that can cause inefficient cooling
- Energy Display Mode: Lets you see how much energy you’re using in real-time
FAQs
What is the best LG aircon for energy savings in Singapore?
The LG Dual Inverter System 2 or 3 with 5 NEA ticks offers great energy efficiency for most HDB or condo homes.
How can I check my aircon’s power usage?
Use a smart energy monitor or check the LG SmartThinQ™ app (for compatible models). You can also refer to the energy label on the indoor unit.
Does an LG inverter aircon really save electricity?
Yes. Inverter aircons can reduce energy use by up to 30–50% compared to non-inverter models by adjusting compressor speed instead of stopping and starting it.
Should I turn off the aircon when I leave the room?
Yes. Alternatively, use the timer or smart scheduling feature so it automatically turns off when not needed.
