Inverter vs Standard AC — Is the Upgrade Worth It?
Standard AC (3-star)
- • Fixed-speed compressor
- • Higher electricity consumption
- • Lower purchase price
- • More temperature fluctuation
Inverter AC (5-star)
- • Variable-speed compressor
- • Up to 30–40% energy savings
- • Higher purchase price
- • More stable temperature
In Malaysia's year-round cooling climate, an inverter unit typically pays back the price premium within 2–3 years.
