What Do the Number of Ticks Mean for Aircon and How Much Do You Save?

Singapore HDB living room with 5-tick energy efficient aircon NEA energy label

If you’ve ever shopped for an aircon in Singapore, you’ve seen the NEA Energy Label with ticks — from 1 tick to 5 ticks. But what do they actually mean? And more importantly, how much money does a higher tick rating actually save you every month? This guide breaks it all down simply.

What Are Aircon Ticks in Singapore?

The tick rating system is run by Singapore’s National Environment Agency (NEA). Every aircon sold in Singapore must display an energy label showing how energy-efficient the unit is — rated from 1 tick (least efficient) to 5 ticks (most efficient).

The ticks are based on the aircon’s Cooling Seasonal Performance Factor (CSPF) — essentially how much cooling you get per watt of electricity consumed. The higher the ticks, the more cooling you get for the same electricity used. This is part of NEA’s Mandatory Energy Labelling Scheme (MELS).

💡 Simple analogy: Think of ticks like a fuel efficiency rating on a car. A 5-tick aircon is like a car that gets 20km per litre. A 1-tick aircon gets 8km per litre. Same journey, very different fuel cost.

What Each Tick Rating Means

Here is a breakdown of what each tick rating represents and what type of buyer it suits:

Tick RatingEfficiencyCSPF RangeBest ForPrice (SGD)
⭐ 1 TickLowBelow 2.6Rarely used rooms$400–$700
⭐⭐ 2 TicksBelow Avg2.6–2.9Occasional use$600–$900
⭐⭐⭐ 3 TicksAverage2.9–3.2Most HDB households$900–$1,300
⭐⭐⭐⭐ 4 TicksHigh3.2–3.5Heavy nightly use$1,200–$1,800
⭐⭐⭐⭐⭐ 5 TicksHighest3.5+24/7 use, WFH$1,500–$2,500+

How Much Do You Actually Save?

Real-world calculation based on a 9,000 BTU aircon running 8 hours per night at Singapore’s electricity rate of $0.29 per kWh (Q1 2026, per EMA Singapore).

Tick RatingPower DrawMonthly CostAnnual CostAnnual Savings vs 1-Tick
1 Tick~1,300W~$91~$1,087
2 Ticks~1,150W~$80~$962Save ~$125
3 Ticks~1,000W~$70~$836Save ~$251
4 Ticks~870W~$61~$727Save ~$360
5 Ticks~750W~$52~$627Save ~$460
Key Takeaway: Over 10 years, a 5-tick aircon saves you roughly $4,600+ in electricity compared to a 1-tick unit — more than enough to cover the price difference.

Which Tick Rating Should You Get?

Your Usage PatternRecommended TicksReason
Guest room, rarely used1–2 TicksSavings won’t justify higher upfront cost
Bedroom, on at night only (6–8 hrs)3 TicksBest balance of cost and efficiency
Living room, on most of the day4 TicksHigher usage justifies better efficiency
WFH, aircon on 10–16 hrs daily5 TicksPays for itself within 3–4 years

Ticks vs Inverter — What’s the Difference?

Many people confuse tick ratings with inverter technology — they are related but not the same thing.

Tick RatingInverter Technology
What it measuresOverall energy efficiencyHow the compressor works
Energy savingHigher ticks = more efficientSaves 30–50% vs non-inverter
RelationshipMost 4–5 tick aircons are inverter. But not all inverter aircons are 5-tick.
💡 Bottom line: Always go for an inverter aircon with at least 3 ticks for everyday Singapore use.

Frequently Asked Questions

Is a 5-tick aircon always worth it?

Only if you use your aircon heavily — 8 hours or more per day. For a guest room used occasionally, a 3-tick unit is more cost-effective.

Do ticks matter more than the brand?

For electricity savings, yes. But brand matters for reliability. Ideally choose a reputable brand (Daikin, Mitsubishi, Panasonic) with the highest tick rating within your budget.

Does a higher tick aircon cool faster?

No. Cooling speed depends on BTU, not ticks. Ticks only measure energy efficiency.

Can I get a grant for buying a high-tick aircon?

Yes. Under Singapore’s Climate Friendly Households Programme, eligible HDB households can receive vouchers of up to $300 to offset the cost of energy-efficient appliances including 3-tick and above aircons.

Will NEA change the tick system in future?

Yes. As of April 2025, NEA raised the MEPS for single-split aircons to 4-tick minimum. Always check the latest NEA tick rating page before buying.
