If you’re planning to buy a new aircon in Singapore, you’ve probably come across the terms inverter and non-inverter. But what’s the real difference? And more importantly — which one is better for your home, energy savings, and monthly bills?
In this article, we’ll explain how an inverter aircon works compared to a non-inverter aircon, break down their pros and cons, and help you decide which type suits your needs and budget. If you’ve been wondering whether an inverter aircon is worth the extra cost or if a non-inverter will do, this inverter vs non-inverter aircon guide will give you the answers you need.
What Is an Inverter Aircon?
First of all, an inverter aircon uses a variable-speed compressor.
In simpler terms, it can adjust its cooling power based on the room’s temperature.
For example, once the room reaches your desired temperature, the compressor slows down but doesn’t completely stop.
As a result, it maintains a steady, comfortable climate without using unnecessary energy.
What Is a Non-Inverter Aircon?
On the other hand, a non-inverter aircon works in a fixed way.
The compressor either runs at full speed or turns off completely.
Because of this, the temperature in the room can fluctuate as the unit switches on and off to maintain your chosen setting.
Inverter vs Non-Inverter: Which Is Better?
Now, let’s compare them side by side:
Energy Efficiency
Firstly, inverter aircons are more energy-efficient.
Since they adjust their speed instead of stopping and restarting, they use less electricity over time.
Non-inverter aircons, however, consume more energy because they keep switching on and off at full power.
Noise Level
Next, inverter aircons are generally quieter.
Because the compressor runs at a lower, steady speed, you’ll notice less noise when compared to non-inverter units.
Price
In terms of price, non-inverter aircons are usually cheaper to buy upfront.
However, inverter aircons can save you more on your monthly electricity bills in the long run.
So, if you use aircon frequently, an inverter model is a smarter investment.
Maintenance and Durability
In addition, inverter aircons tend to experience less wear and tear since their compressors don’t constantly start and stop.
As a result, they typically last longer with fewer major breakdowns.
So, Which One Should You Choose?

In conclusion, if you’re looking for lower electricity bills, quieter operation, and long-term value, an inverter aircon is the better choice.
However, if you only use aircon occasionally or prefer a lower upfront price, a non-inverter aircon might suit your needs just fine.
