KUALA LUMPUR, 30 JULY 2026 —
Aircond inverter models rated five stars by the Energy Commission can reduce household power bills by up to 40% compared with non-inverter units, according to industry technical guidance.
Market Impact
The savings come from inverter technology that runs the compressor at variable speed rather than switching it fully on and off. A non-inverter unit cycles between full power and idle, causing large power surges every time it restarts, while an inverter unit slows the compressor once the target temperature is reached and maintains it without sudden stops and starts, the guidance states.
Households in Malaysia spend an average RM150 to RM300 a month on air-conditioning during peak periods, according to the Energy Commission. An inverter unit rated five stars typically recovers the higher upfront cost within 12 months through lower monthly bills, the guidance says.
Technical installation mistakes can erase potential savings before the unit is even switched on. Choosing the wrong horsepower for room size forces the compressor to overwork or short-cycle, both of which increase electricity use. A 1.0HP unit in a large living room must run continuously at maximum load, while an oversized unit in a small bedroom will cycle on and off repeatedly, each start drawing a large inrush current.
Dirty air filters are another common cause of higher bills. Clogged filters restrict airflow, causing the cooling coil to overcool and form ice. When the ice melts, excess condensate can overflow the drain tray and leak from the indoor unit. The guidance advises cleaning filters every two weeks and ensuring the drainage pipe is installed without kinks or sharp bends.
Positioning of the indoor unit also affects efficiency. Blocking the airflow with large furniture or placing the unit where afternoon sun heats the wall behind it forces the sensor to misread the room temperature. Engineers recommend a clear path for air circulation and avoiding direct sunlight on the indoor unit’s sensor side.
All air-conditioning systems lose efficiency when neglected, the guidance warns. Dust accumulation on coils and filters increases motor load and can freeze the coil, leading to water leaks and higher power consumption. Regular professional servicing every six months helps maintain the inverter’s efficiency edge.
For consumers seeking a benchmark, the Acson Avory Premium and Acson Reino+ series carry five-star Energy Commission ratings and use proprietary inverter compressors designed for Malaysian homes.
