Knowing the differences between inverter vs non-inverter air conditioning systems is essential when selecting a new air conditioner in Malaysia. Malaysians are increasingly searching for energy-efficient cooling options due to the country’s constant hot and muggy weather, as well as the rising cost of electricity under TNB’s updated tariffs.
So, should you go with a non-inverter or an inverter air conditioner? Let’s explore the differences, pros and cons, and real-world savings potential.
What Is an Inverter Air Conditioner?
An inverter air conditioner uses advanced technology that allows the compressor to adjust its speed according to the room’s cooling needs. Instead of constantly turning on and off, it maintains a steady temperature, using less power over time.
How Does Inverter Technology Work?
- When you first turn on the aircond, the inverter ramps up the compressor to cool the room quickly.
- Once the target temperature is reached, it slows down (not shuts off) which allowing the system to run efficiently at low power while keeping the room consistently cool.
- This reduces energy spikes, improves performance, and extends the lifespan of the unit.
♻️Inverter Aircond - For Better for the Environment
Inverter air conditioners are not just more efficient, but they’re also more environmentally friendly:
- They consume up to 30–50% less electricity, lowering your carbon footprint.
- Most models use R32 refrigerant, which has lower global warming potential (GWP) compared to older gases.
- By reducing energy waste and operating more quietly, inverter ACs help create a greener, more sustainable home.

These models are well-known for their energy-saving capabilities and are often recommended for homeowners looking to reduce their monthly electricity bills:
What Is a Non-Inverter Air Conditioner?
A non-inverter air conditioner operates on a fixed-speed compressor, meaning it either runs at full power or turns off completely. When you switch on the unit, the compressor works at maximum speed to cool the room. Once the set temperature is reached, the system shuts off. It then restarts when the temperature rises again, repeating this on-off cycle throughout its usage.
How Does a Non-Inverter Aircond Work?
- No speed variation where the compressor runs at one speed only.
- Cooling cycle: On → cools → off → warms → on again
- Power spikes every time it restarts, which increases electricity consumption.
Key Differences: Inverter vs Non-Inverter Aircond

Slower and fluctuates more |
Noise Level |
Quieter operation (no frequent compressor restart) |
Noticeable noise during compressor start-up |
Cost (Upfront) |
Relatively high initial price |
More budget-friendly |
Best Use |
Daily use, long-term savings |
Occasional use or short-term tenancy |

Which Aircond Should You Buy in Malaysia?
Choosing between an inverter and non-inverter air conditioner depends on how you use your aircond, your living space, and your long-term plans. Here’s how to decide which type suits your lifestyle best.
| User Scenario | Recommended Type | Reason | Suggested HP |
|---|---|---|---|
Homeowner (landed or condo) |
Inverter |
Daily use, long-term savings, energy-efficient for large spaces |
1.5–2.5HP |
Tenant / Student (rental unit) |
Non-Inverter |
Occasional use, lower upfront cost |
1.0–1.5HP |
Small apartment / studio |
Inverter or Non-Inverter |
Depends on usage hours; inverter for frequent use, non-inverter for rare use |
1.0–1.5HP |
Work-from-home / Long daily usage |
Inverter |
Runs 8+ hours daily, inverter reduces monthly TNB bills |
1.5–2.0HP |
Guest room / Occasional use only |
Non-Inverter |
Infrequent use, cost-saving for backup rooms |
1.0HP |
Budget-conscious buyer |
Non-Inverter |
Lower purchase price, ideal if usage <4 hours/day |
1.0–1.5HP |
Environmentally conscious household |
Inverter |
Lower carbon footprint, quieter, qualifies for energy rebates |
1.5–2.0HP |
Tips to Maximise Efficiency (Regardless of Type)
You may wonder how much electricity an air conditioner consumes. Regardless of the type of air conditioner you use, these practical tips will help you reduce electricity consumption, improve cooling performance, and extend your unit’s lifespan, especially in Malaysia’s hot weather and with rising TNB tariffs.
✅ Use a BTU calculator to choose the right HP based on your room size as oversized or undersized unit leads to energy waste.
✅ Clean air filters every month to maintain smooth airflow and prevent strain on the compressor.
✅ Set the temperature between 24°C and 26°C as this range balances comfort and electricity savings in Malaysia’s climate.
✅ Keep doors and windows fully closed when the aircond is running to prevent cool air from escaping.
✅ Schedule professional servicing every 6–12 months to keep your unit running efficiently and extend its lifespan.
✅ Use energy-saving or eco mode (if available) to reduce electricity usage without compromising cooling.
✅ Avoid placing heat-emitting devices near the AC sensor — they can cause the unit to overcool unnecessarily.
✅ Install curtains or window tinting to block out direct sunlight and reduce indoor heat gain.
✅ Utilise timers or smart plugs to switch off the unit after sleep hours automatically or when you’re not home.
✅ If you have a smart meter (TNB Time-of-Use plan), run heavy cooling during off-peak hours to take advantage of lower rates.
Conclusion: Choose the Best Aircon for Your Needs
When deciding between an inverter and a non-inverter air conditioner in Malaysia, the best choice depends on your usage patterns, budget, and long-term priorities. Given Malaysia’s tropical climate and rising electricity costs, an energy-efficient inverter AC (preferably a 5-star rated model from trusted brands like Daikin, Panasonic, or Mitsubishi) is the best long-term investment for most users.
However, if your usage is minimal or temporary, a non-inverter unit can still be a practical, cost-effective solution. By carefully assessing your cooling needs, budget, and energy consumption, you can select the ideal air conditioner to maximize comfort while minimizing expenses. Stay cool and energy-smart!
FAQs: Inverter vs Non‑Inverter Aircond for Malaysia
Is an inverter air conditioner better in Malaysia?
Yes. Especially given rising tariffs and high usage, inverter models offer better efficiency, comfort, and potential rebate benefits.
How much electricity does an inverter aircond use/month?
Approximately 1.1–1.2 kWh/hour for a 1.5 HP unit. Significant savings accrue compared to non-inverters, depending on usage hours.
Why is a non-inverter aircond cheaper?
They use simpler compressor technology, so manufacturing costs are lower but electricity bills may be higher in the long run.
How long do inverter air conditioners last?
With proper maintenance, they can last over 10–15 years, often longer than non-inverter counterparts.
Is it worth upgrading from a non-inverter to inverter?
If you regularly use your AC for many hours daily, the upfront extra cost is often recouped within a year or two, especially with usage-based tariffs and rebates.
Does an inverter aircond cool faster?
Yes. They spin up faster to reach the set temperature, avoiding frequent cycling and providing faster and steadier cooling.
Which inverter aircond brands are best in Malaysia?
Daikin, Panasonic, and Midea consistently earn strong user feedback on long-term reliability and energy savings.
