Today in this Article we gonna cover the difference between Inverter vs Dual Inverter AC. Air Conditioners are the most important thing in modern households. On the hot summer days when the mercury level in the thermostat increases the thing that will give relief and relaxation from this situation is an Air conditioner.
However, when looking for an Air Conditioner you might come across the dual inverter. So is it worth the money well this post contains all of your doubts regarding this topic. So let’s jump into the main topic without wasting any more time.

What is Inverter AC?
Inverter technology was produced by Japanese major appliance producer Toshiba in 1980. Inverter technology revolutionised the air conditioner market.
With an inverter AC, it uses a BLDC motor unlike ac motor used in non-inverter ones. So, the compressor speed can be altered continuously to meet cooling demand. Whereas with normal air conditioners, the compressor can either work at maximum capability or be switched off. Because the compressor’s speed cannot be varied.

As a result, compared to non-inverter ac, an inverter ac can maintain room temperature to the set temperature in the air conditoner without frequently restarting the compressor. This way saves a lot of energy almost 20-30% energy and also increases the efficiency and lifespan of the components of your air conditioners.
What is Dual Inverter Technology?
The main component in AC is its compressor you can call it the heart of an Air conditioner. In terms of the dual inverter, the compressor design is taken to a whole new level. So unlike a normal inverter a dual inverter ac comes with more advanced BLDC motor technology. Also, dual inverter ac works on a twin rotary compressor and consists of two compression chambers.

So with the help of a twin rotary compressor, it can produce a 180° phase difference in the compression timings of the two chambers. As a result, the load is divided into both of them which results in less vibration and also less energy loss. Additionally, due to the operation of twin rotary compression, the machine is more stable, thus resulting in less noise, reduced energy consumption, and faster cooling.
Dual Inverter AC Advantages and Disadvantages
Power Consumption
So the power consumption for the Dual inverter will be much lower. Because it uses a twin rotary for refrigerant compression. Whereas the inverter AC Comes with a single rotary. Thus it will require a higher frequency of rotation to achieve the goal means it will consume more power.
Noise
As your dual inverter AC uses a twin rotary compressor, it can produce a 180° phase difference in the compression timings of the two chambers which results in much lower vibration and further reduces the noise level of the particular Air Conditioners model in contrast to the single rotary compressor.
Cooling Time
The Twin Rotary used in dual inverter AC works much faster in refrigerant compression compared to inverter ac or single rotary. This also results in faster cooing.
Lifespan
The Lifespan of the components used in the dual inverter AC is also further increased. Unlike single rotary inverters dual inverters use twin rotaries that distribute the workload to both rotaries equally thus they don’t have to work at their full capacity. As a result, it will have a much longer life.
Variable Tonnage
A dual inverter uses twin rotary compressors. Two compression chambers produce a 180° phase difference. Besides improving rotational balance, this also boosts compression torque, allowing the compressor to run at 720 RPM up to 9000 RPM at its peak.
Because of this, dual inverter ACs can handle variable loads. As a result, a 1.5-ton AC with dual rotary inverters has the capability of varying its tonnage from as low as 0.25 tons to as high as 1.7 tons.
Price
Twin rotary used in dual inverter AC also increased the price tag of air conditioners compared to a normal AC. However, the price also depends on the brand to the brand.
Many AC brands market this technology as per their models. For example, LG calls it a dual inverter, Toshiba and O’General call it a twin inverter and Blue Star labels it a dual inverter rotary compressor. So the price for the Toshiba and general is much higher than LG and Blue Star.
Not that the installation charge and maintenance cost is also much higher for the dual inverter one.
Inverter Vs Dual Inverter AC Differences
Parameters | Inverter AC | Dual Inverter |
---|---|---|
Compressor | Inverter AC uses a single-rotor compressor. | Dual inverter AC uses a twin rotor Compressor. |
Cooling Performance | Interns of inverter ac the single rotor will take more time as it has to do the task single-handedly. | The dual rotor can work faster in refrigerant compression resulting in faster cooling. |
Power Consumption | Inverter Air Conditioners are also power savers, but only when this comparison is limited to non-inverter models. | Again compared to an inverter a dual inverter has extremely low power consumption. |
Noise | Compared to non-inverter AC, the inverter makes less noise. Although not as low as dual inverter AC. | Dual rotors used in dual inverter AC spin opposite to both this creates more stable operation and less noise. |
Variable Tonnage | Not all inverter ac support this. | Dual inverter AC can vary its tonnage as per external loads. |
Lifespan | Inverter ACs also last longer compared to their non-inverted counterparts. | Dual inverter AC lasts much longer thanks to its twin rotors. |
Price | Compared to non-inverter ACs, inverter ACs have a high price tag. but not as much as Dual inverter Acs. | Dual Inverter Acs are slightly more pricey. |
FAQs: Inverter vs Dual Inverter AC
1. Do LG Dual Inverter AC need stabilizer?
LG says that the dual inverter AC supports stabilizer-free operation although you should get a stabiliser to stay in a safe zone.
2. How Set timer in LG dual Inverter AC?
To set the temperature you first have to press the timer icon. Then press on adjust keys and just located at the side of the timer icon. After adjusting the time using these keys you have to press the ‘set/cancel’ and be done.
3. Is LG Dual Inverter AC Worth buying?
Yes LG Dual Inverter AC is Worth buying for home usage but it’s recommended for store or office usage, for that you have to pick non-inverter ac.
4. Why my LG AC isn’t cooling?
So there are multiple reasons behind your air conditioners not cooling. One of them is that the air filter and condenser get clogged or even if it has low refrigerant gas left.
5. Does Dual Inverter AC really saves electricity?
Yes, Dual Inverter AC really saves electricity.
6. What is difference between split inverter AC and dual inverter AC?
Split AC is a type of AC and a Dual inverter is a technology that is used in an AC. Now Split Inverter AC has only a single rotor whereas dual inverter AC has a dual rotor.
