⚡ Quick Answer
The yellow energy label shows the star rating (1–5), CSPF value, and annual energy use. 5-star units use 40–50% less electricity than 1-star. In 2026, the standards got stricter — the MEPS requirement is now 2 stars, and 1-star units can no longer be sold. The label also includes a QR code for verification. This guide will help you translate stars into actual ringgit savings on your TNB bill.

What Is the Malaysia Aircond Energy Label?
The yellow sticker on the side of every new air conditioner sold in Malaysia is the official Energy Efficiency Label, issued by Suruhanjaya Tenaga (the Energy Commission).
It tells you exactly how efficient an aircond is before you buy it. The more stars it has, the less electricity it uses to cool your room. Simple, right?
But here’s the thing – most Malaysians know more stars means “better,” but very few actually know how to translate that into real ringgit savings on their TNB bill. This guide will change that.
The label is mandatory for every residential air conditioner sold in Malaysia with a cooling capacity of 7.1 kW or less – which covers basically every domestic split unit from 1HP up to 2.5HP.
Before we dive in, here’s the most important thing to know: The MEPS (Minimum Energy Performance Standard) requirement in Malaysia is 2 stars. Any aircond below 2 stars cannot legally be sold in Malaysia.
📢 2026 Update — Important Changes!
From 1 January 2026, Suruhanjaya Tenaga implemented a new, stricter star rating schedule. What used to be a 4-star unit might now only qualify for 3 stars under the new criteria. The bar has been raised — and all new labels now include a QR code for verification. When comparing units, always check the year on the label.
What Does MEPS Mean and Why Does It Matter?
MEPS stands for Minimum Energy Performance Standard.
It’s a regulation enforced by Suruhanjaya Tenaga that sets the minimum efficiency level every air conditioner must meet before it can be sold in Malaysia.
Think of it as a legal baseline. Any aircond that doesn’t meet this standard is simply not allowed on the market.
Here’s what you need to know:
- ✅ The MEPS requirement is 2 stars. A 1-star aircond is no longer compliant and cannot be sold new in Malaysia.
- ✅ MEPS is part of the Energy Efficiency and Conservation Act (EECA) 2024, which took effect on 1 January 2025.
- ✅ Manufacturers and importers must now obtain a Certificate of Energy Efficiency (COE) before distributing air conditioners in Malaysia.
Why should you care? Because MEPS protects you from buying an electricity-guzzling dinosaur. Every aircond you see in a store today – from the cheapest budget unit to the most premium model – has at least passed this minimum bar. But that doesn’t mean they’re all equally good for your wallet.
How to Read the Energy Label – Section by Section
Let’s walk through the yellow sticker together.
1. Star Rating (1 to 5 Stars)
This is the biggest, most obvious feature on the label. More stars = more efficient.
- 5 stars – Most efficient. Highest energy savings.
- 4 stars – Very efficient. Excellent energy savings.
- 3 stars – Good efficiency. Average savings.
- 2 stars – Minimum legal standard (MEPS). Still allowed, but expect higher electricity bills.
- 1 star – No longer allowed for new units in Malaysia.
2. CSPF Value (Wh/Wh)
CSPF stands for Cooling Seasonal Performance Factor. This is the real efficiency number behind the stars. It measures how much cooling an aircond delivers compared to the electricity it consumes over an entire year. The higher the CSPF number, the more efficient the unit.
3. Brand and Model Number
This helps you cross-check the unit against the ST product database. If the model doesn’t match what’s registered, something is wrong.
4. ST Approval Number
This is the official certification number from Suruhanjaya Tenaga. Every genuine unit has one.
5. Annual Energy Consumption
Some labels show estimated yearly electricity consumption in kWh. This gives you a rough idea of running costs.
6. QR Code
Starting from the 2026 label update, each label now includes a QR code. Scanning it brings up detailed information about the appliance’s Energy Efficiency Certificate, including its approval status and efficiency data.
What the Star Ratings Actually Mean (2026 Update)
Here’s where things get interesting – and where most Malaysians get confused.
From 1 January 2026 to 31 December 2029, Suruhanjaya Tenaga has implemented a NEW star rating schedule.
The thresholds have been raised. What used to be a 4-star unit might now only qualify for 3 stars under the new, stricter criteria.
📌 Air Conditioners Under 4.5kW Cooling Capacity (1HP – 1.5HP)
📌 Air Conditioners 4.5kW – 7.1kW Cooling Capacity (2HP – 2.5HP)
💡 Important: The 2026 update also sets a future target – MEPS requirements are set to increase to even higher levels by 2030, aligning with regional roadmaps. This means efficiency standards will only get tougher.
What Is CSPF and Why Should You Care?
You’ve seen the acronym. Now let’s actually understand it.
CSPF = Cooling Seasonal Performance Factor.
It measures the total annual cooling an air conditioner provides divided by the total annual electricity it consumes.
Why does this matter more than the old EER rating?
Older systems used EER (Energy Efficiency Ratio), which measured performance at a single, fixed temperature. That’s like testing a car’s fuel efficiency only on a flat highway – it doesn’t reflect real-world driving.
CSPF, on the other hand, measures performance across different temperatures throughout the year. It gives you a much more accurate picture of what you’ll actually pay on your TNB bill.
🔑 Key Points:
- ✅ CSPF is measured in Wh/Wh (watt-hours per watt-hour).
- ✅ Higher CSPF = more efficient = lower electricity bills.
- ✅ For inverter airconds, the CSPF calculation accounts for variable compressor speeds, which is why inverters typically achieve higher CSPF ratings.
- ✅ For non-inverter units, CSPF is derived from tested EER values.
When comparing two airconds, always compare CSPF values — not just the star rating. A unit with a higher CSPF will save you more money, even if both have the same number of stars (especially during the transition period with old and new labels).
How Much Does Each Star Rating Save You on Your TNB Bill?
This is the question everyone actually wants answered.
A 5-star 1HP aircon typically uses 40% to 50% less electricity than a 1-star unit of the same size.
For a bedroom running 8 hours a night, that works out to roughly RM150 to RM250 in annual savings.
*Actual costs vary based on usage, TNB tariff rates, room size, and climate conditions.
🧮 Let’s do the math: If a 5-star unit costs RM500 more than a 2-star unit, but saves you RM200 per year on electricity, it pays for itself in 2.5 years. After that, every ringgit saved is money back in your pocket.
💡 Expert tip: If you use your aircond daily (especially overnight), always go for the highest star rating you can afford. The upfront premium pays back quickly. If you only use it occasionally, a 3-star unit might be the sweet spot.
To maximise your savings, pair a high-star aircond with regular servicing and chemical washes — a dirty unit uses more electricity regardless of its star rating.
How to Check If a Label Is Genuine
Fake or expired labels do exist. Here’s how to protect yourself:
Check the Year on the Label
If the label shows 2026 or later, it follows the new star rating schedule. If it shows an earlier year, it follows the old schedule – but this doesn’t automatically mean it’s fake. Older certified units can still be sold until their certificate expires.
Scan the QR Code
Every new label has a QR code. Scan it. It should take you to the official Energy Efficiency Certificate with full approval status and efficiency data.
Cross-Check the Model Number
Visit the Suruhanjaya Tenaga website at www.st.gov.my/eeca and check if the model number appears in the registered product database.
🚫 Walk Away If…
- There’s no yellow label at all.
- The label looks photocopied, low quality, or hand-drawn.
- The price is too good to be true for a supposedly high-star unit.
Old Labels vs New Labels – What’s the Difference?
This is a common point of confusion right now.
⚠️ What this means for you: A 5-star label from 2025 might not qualify as 5-star under the 2026 standards. The bar has been raised. So when comparing units, always check the year on the label.
During the transition period, you’ll see both old and new labels in stores. Units that received certification before 1 January 2026 can continue using their existing labels until expiry. New applications from 2026 onward must meet the higher standards.
Final Verdict — Which Star Rating Should You Buy?
Here’s my straightforward advice:
💡 The bottom line: The yellow energy label isn’t just a sticker – it’s your guide to saving hundreds of ringgit every year. Take two minutes to read it before you buy, and your future self (and your TNB bill) will thank you.

Frequently Asked Questions
Questions About Aircond Energy Labels
Honest answers based on Suruhanjaya Tenaga regulations and real-world experience.
❓Is a 1-star aircond still available in Malaysia?
No. The MEPS requirement is now 2 stars. 1-star units are no longer compliant and cannot be sold new in Malaysia.
❓What is the MEPS requirement for air conditioners in Malaysia?
The MEPS (Minimum Energy Performance Standard) requirement is 2 stars. All air conditioners sold in Malaysia must meet at least this standard.
❓What does CSPF mean on an aircond energy label?
CSPF stands for Cooling Seasonal Performance Factor. It measures the total annual cooling provided divided by the total annual electricity consumed. Higher CSPF = more efficient.
❓Do inverter airconds always have higher star ratings?
Generally, yes. Inverter technology allows the compressor to vary its speed, which significantly improves efficiency. This is why most 5-star units are inverter models.
❓How much can I save with a 5-star aircond?
A 5-star 1HP aircon typically uses 40% to 50% less electricity than a 1-star unit. For a bedroom running 8 hours a night, that’s roughly RM150 to RM250 in annual savings.
❓What if my aircond doesn’t have an energy label?
If you’re buying new, don’t buy it. The label is mandatory. If it’s missing, the unit is either illegally imported, counterfeit, or not registered with Suruhanjaya Tenaga.
❓How do I verify if a label is real?
