Aircon Energy Label
Air conditioners (along with refrigerators) almost significantly influence the energy consumption and cost of any household. And because air conditioning units are almost everywhere in Singaporean homes, the National Environment Agency (NEA) has devised a scheme behind the aircon energy label. The aircon energy label, essentially, points consumers to energy-efficient air conditioners.
The NEA makes it mandatory for all retailers of air conditioning units in Singapore to include an energy label. The energy label must follow the rigorous tick rating convention created by the NEA, and it must be attached prominently to the air conditioning units being sold in Singapore. Refer to the NEA diagrams below for the mandated placements of aircon energy labels.
Lastly, for split-type air conditioning systems, the energy label is attached to the condenser (outdoor unit). If only the indoor unit is displayed at a retail outlet, the energy labels for all compatible outdoor unit configurations must also be displayed alongside the indoor unit.
A Background on Singapore’s Mandated Energy Labeling Scheme (MELS)
The Mandatory Energy Labelling Scheme (MELS) was created by the NEA to enable Singaporean residents to make environmentally-conscious buying decisions when it comes to selecting household appliances, most notably air conditioners and refrigerators. Essentially, the Minimum Energy Performance Standards (MEPS) is NEA’s way to elevate the average energy-efficient standards of regulated goods in the Singaporean market. By April of 2025, the MEPS for “single-split air-conditioners [is] to be raised to 4-tick” and “multi-split air-conditioners to be raised to 5-tick.” All in all, this means a more rigorous energy labeling scheme and implementation of the tick-rating system.

The Basics of the Tick-Rating System
The NEA’s energy-labeling scheme is based on the tick-rating system. In short, the more ticks, the higher the electricity savings. To simplify further: view the image here

OUR TESTIMONIALS
Which Air Conditioning Units Carry a 4 or 5-Tick Energy Label?
Silverback Aircon’s catalog has quite a selection of air conditioners that have a 4 or 5-tick rating, in case you are shopping around to invest in highly energy-efficient units. They include leading aircon brands such as Mitsubishi, Daikin, Midea, and Panasonic. However, proper installation is also contingent with maximizing the energy-efficiency features of your chosen aircon. So, consider hiring a professional to carry out the aircon installation.

Tips for Choosing Energy-Efficient Air Conditioners
In selecting air conditioners with an eye towards long-term energy savings, the NEA recommends correctly sizing an air conditioning unit. A smaller aircon capacity will run fruitlessly, drawing more and more electricity in the process. Accordingly, the said unit will struggle to cool a room and still barely maintain the temperature setting. In contrast, a large aircon will cool a room fast and then cycle frequently. Overall, it will draw more electricity than is normal. Thus it is important that you choose the correct aircon setup.
Additionally, the NEA suggests choosing models with lower life cycle costs (LCC), where LCC = Purchase Price + Estimated Electricity Cost over 7 years Lifespan (Annual Energy Cost × 7). A handy calculator for computing LCCs can be found here. Overall, a cheap air conditioning unit with high power consumption can negate your initial savings. In the long run, it makes for a poorly thought-out purchase decision.
Silverback Aircon Will Help You Get the Best Deal on a 5 Tick Aircon Energy Label
Meanwhile, here at Silverback Aircon, we’d love to assist Singaporean households in their $300 Climate Vouchers to purchase energy-efficient air conditioners and other approved cooling products. The vouchers, part of the government’s efforts to promote sustainability, help offset costs while encouraging eco-friendly choices. Eligible residents can redeem them at participating retailers, including Silverback Aircon, which offers compliant products and professional installation services. Finally, our Climate Voucher page provides details on voucher eligibility, redemption steps, and the benefits of upgrading to energy-saving appliances.
