Difference Between an Inverter and Non-Inverter Air Conditioner

A question that is often asked is “what is the difference between an inverter and non-inverter air conditioner”

As an air conditioning e-commerce brand, we have listed some common and beneficial differences between the two types of air conditioner.

Inverter and non-inverter air conditioners are two different types of systems that regulate the speed of the compressor motor to control the temperature of a room. Here are the key differences between the two:

Compressor Operation:

Inverter AC: The compressor in an inverter air conditioner operates at variable speeds. It adjusts its speed according to the cooling or heating needs of the room. This results in more precise temperature control and energy efficiency.

Non-Inverter AC: The compressor in a non-inverter AC operates at a fixed speed. It either runs at full capacity or turns off completely when the desired temperature is reached. When the compressor is off, the temperature tends to fluctuate more.

Energy Efficiency:

Inverter AC: In general, inverter air conditioners are more energy-efficient compared to non-inverter models. The ability to adjust the compressor speed reduces energy consumption as the system doesn’t have to start and stop frequently.

Non-Inverter AC: Non-inverter air conditioners are generally less energy-efficient because they operate at a fixed speed, leading to more power consumption during constant on-and-off cycles.

Temperature Control:

Inverter AC: Provides better and more precise temperature control. The compressor adjusts its speed to maintain a steady and comfortable temperature.

Non-Inverter AC: Tends to have more temperature fluctuations since the compressor operates in an on-off cycle. This can lead to the room temperature overshooting or falling below the set temperature.


Inverter AC: Initial purchase costs for inverter AC units are usually higher compared to non-inverter models. However, the long-term energy savings can offset the higher upfront investment.

Non-Inverter AC: Typically has a lower initial cost, but the higher energy consumption may result in higher electricity bills over time.

Noise Level:

Inverter AC: Generally quieter because the compressor operates at lower speeds most of the time.

Non-Inverter AC: Can be noisier, especially during the start-up phase when the compressor operates at full capacity.


Inverter AC: The ability to operate at variable speeds may reduce wear and tear on the compressor, potentially contributing to a longer lifespan.

Non-Inverter AC: The compressor experiences more stress during on-off cycles, which may contribute to a shorter lifespan compared to inverter models.


In summary, inverter air conditioners offer better energy efficiency, temperature control, and quieter operation compared to non-inverter models. However, non-inverter AC units may be more budget-friendly in terms of initial purchase cost. The choice between the two depends on individual preferences, budget constraints, and long-term energy efficiency considerations.
