Is Inverter Aircond Really Worth It? Pros, Cons & Electricity Savings + How Inverter Technology Works
If you're planning to install a new aircond in Malaysia, you've probably heard the term inverter aircond. But is it really worth paying more? How does it work? And how much electricity can you save every month? This guide explains everything in simple, non-technical language.
💡 How Inverter Aircond Technology Works
What Is an Inverter Compressor?
An inverter compressor can change its speed automatically based on room temperature. Instead of switching ON and OFF repeatedly like a non-inverter unit, an inverter runs continuously at the most efficient speed.
Simple Example
- Non-Inverter: Always ON at 100% → stops → restarts → repeats.
- Inverter: Starts fast → slows down → maintains cool temperature.
Why This Saves Electricity
- No power spikes from ON/OFF cycles
- Lower compressor speed uses less watt
- Maintains cooling efficiently
- Less strain on components
❄️ Is Inverter Aircond Really Worth It?
✔ Pros of Inverter Aircond
- Lower electricity bill — 20–40% savings
- Smoother, stable cooling temperature
- Quieter indoor & outdoor unit
- Faster cooling on startup
- Ideal for long hours (bedroom, living room)
✘ Cons of Inverter Aircond
- Higher initial cost
- PCB/board repairs can cost more
- Needs good wiring & stable voltage
⚡ Electricity Savings
Power Consumption Comparison (Average Watt)
| Horsepower | Non-Inverter | Inverter |
|---|---|---|
| 1.0 HP | 900W – 1100W | 350W – 750W |
| 1.5 HP | 1200W – 1500W | 500W – 1000W |
Monthly Electricity Bill Comparison
Based on TNB rate RM0.516/kWh
1.5HP — 8 hours per night
- Non-Inverter: ~ RM170–RM180 / month
- Inverter: ~ RM80–RM90 / month
Average monthly savings: RM90–RM120
Yearly savings: RM1080 – RM1440
📌 When You Should Choose Inverter Aircond
- You use aircond > 6 hours daily
- You want stable temperature and comfort
- You want long-term electricity savings
- You stay in a hot room facing afternoon sun
🧊 When You Should NOT Choose Inverter
- Short usage (1–2 hours per day)
- Very small rooms (6000–7000 BTU)
- Old houses with unstable wiring
