Understanding Energy Star Ratings & How to Save Electricity with Your Aircond in Malaysia
Buying a new air conditioner isn’t just about picking your favourite brand or design — it’s also about making a smart, energy-efficient choice that saves you money every month. If you’ve ever noticed the star rating stickers (2-star, 3-star, 4-star, 5-star) on your aircond box and wondered what they actually mean, this guide is for you.
⭐ What Are Energy Star Ratings?
Energy star ratings in Malaysia are issued by the Energy Commission (Suruhanjaya Tenaga) to show how efficiently an appliance uses electricity. The more stars, the better the energy savings. Airconds with 4 or 5 stars are designed with inverter technology that automatically adjusts cooling power — helping reduce energy waste and maintain steady room temperature.
🌡️ What’s the Difference Between 2-Star and 5-Star Models?
- 2-Star: Basic models, usually non-inverter, consume more power to maintain cooling.
- 3-Star: Mid-range efficiency, slightly lower electricity usage but still less optimized.
- 4-Star: Efficient inverter units that can save up to 40% on your monthly bills.
- 5-Star: Premium inverter airconds that use the least electricity — perfect for long daily usage.
So, if you’re running your aircond for long hours — say, in your bedroom or office — a 5-star inverter unit may cost a bit more upfront, but it can pay for itself in electricity savings within the first year or two.
💡 How Much Electricity Does an Aircond Use?
Electricity usage depends on several factors, including your aircond’s horsepower (HP), star rating, and how long you run it daily. For example:
- 1.0 HP non-inverter (2-star): Around 750W – 850W per hour
- 1.0 HP inverter (5-star): Around 400W – 500W per hour
That means using a 5-star inverter unit can save up to 40–50% in energy costs compared to older models.
🔌 5 Easy Ways to Save Electricity at Home
- Set your temperature between 24°C–26°C — each degree lower increases power usage by about 10%.
- Clean your air filter every 2–4 weeks for smoother airflow.
- Schedule regular servicing to remove dust buildup and improve efficiency.
- Keep doors and windows closed while cooling your room.
- Choose an inverter aircond with 4 or 5 stars from trusted brands like Panasonic, Haier, or Midea.
