What Is an Inverter AC Unit?
Simply put, an Inverter AC unit is a type of AC unit that is electronically controlled and it varies the speed of AC compressor to produce the desired temperature.
How does an inverter AC work?
The operation of an inverter AC unit is very simple and easy. It works on the basic principle of calculating the heat loss of a room and then adjusting the AC to meet the heat loss of the room.

The working principle of an inverter AC is similar to that of a car engine. A car engine has a fuel pump that provides fuel to the engine. The engine then converts it into power and then transfers it to the wheels using a transmission. Similarly, an inverter AC unit converts the electricity to power and then uses it to cool the room.
Pros & Cons of Inverter AC- Inverter Vs Non Inverter AC Unit
Pros
- Energy Efficient: An Inverter AC uses very low energy when compared to a non-inverter AC. The energy consumed by an inverter AC is pretty low as it has sensors, cooling, and heating capacity control along with smart technology. As most of us are aware of the electricity tariff hike in India, inverter AC is the most suitable option for all of us.
- Quiet: Inverter AC units are very quiet as compared to traditional non-inverter AC units. The technology used in inverter AC units makes them very quiet as there are no moving parts inside the unit except for the compressor which hardly makes any sound.
- Good Investment: An inverter AC is a good investment as it has a longer life than that of a non-inverter AC. Moreover, technology is changing very rapidly and an inverter AC will always be up to date with the latest technology as compared to the non-inverter units.
- Equipped with various modes: As most of us are now aware of the electricity tariff hike in India, there are various modes in an inverter AC unit to help us save electricity and money. The various modes include Power Saver Mode, Turbo Cool Mode, Sleep Mode, Auto Mode, Dry Mode, Auto Restart Mode, Fan Only Mode, and Auto Clean Mode.
Cons
- Expensive: Yes, this is one of the major disadvantages of an inverter AC unit as it is more expensive than a non-inverter AC unit but for those who are looking for something more than just cooling their room, an inverter AC unit is worth investing in. Moreover, it provides better comfort, energy-saving, noise reduction etc.
What Is a Non Inverter AC Unit?
A non-inverter AC unit also called a fixed-speed AC is an air conditioner (AC) that does not have an inverter.
The speed of the AC unit’s compressor is constant, regardless of the outside temperature.
The rate at which the AC unit removes heat from the room depends on the difference between the inside and outside temperatures.
How Does a Non-inverter AC Work?
A non-inverter AC unit is also called a fixed-speed AC. The speed of the AC unit’s compressor is constant regardless of the outside temperature.
The rate at which the AC unit removes heat from the room depends on the difference between the inside and outside temperatures.
A non-inverter AC Unit works by using a compressor to pressurize a refrigerant gas. This gas is then cooled and condensed by an evaporator.
The refrigerant gas is then pressurized again and recycled through the compressor and evaporator. This process is called a closed-loop cycle.
Pros & Cons of Non Inverter AC- Inverter Vs Non Inverter AC Unit
Pros
- Cheaper: The main advantage of Non-inverter AC Unit is that they are cheaper compared to Inverter AC Unit
Cons
- Noisy: Non Inverter AC units are much noisier than Inverter AC units. The compressor used in a non-inverter AC unit is usually larger in size and generates more noise (hissing, rattling, etc.) than the compressors used in inverter AC units.
- Shorter Life Span: Non Inverter AC units have a shorter life span than Inverter AC units. The compressor used in a non-inverter AC unit is usually larger in size and generates more noise (hissing, rattling, etc.) than the compressors used in inverter AC units. Since they are larger in size, they will wear out more quickly than the compressors on an inverter AC unit.
Technical Comparison-Inverter Vs Non Inverter AC Unit
Compressor Unit Comparison:
Inverter AC units have a variable speed compressor i.e. the compressor runs at variable speeds depending on the load requirement.
Non-Inverter AC units have a fixed speed compressor that runs at a fixed speed of 1800 rpm. This is because non-inverter AC units are designed to run on 220/240 V whereas inverter AC units are designed to run on 230/240 V.
Non-inverter AC units are typically bulky in size because of the larger motor and the heavy transformer. This reduces the life of the compressor, thereby reducing the overall life expectancy of the unit.
Functionality and Efficiency Comparison:
Inverter AC units have a 2 stage functionality i.e. cooling and dehumidification whereas non-inverter AC units have only 1 stage functionality i.e. cooling.
Inverter AC units are more efficient because they run at variable speeds and hence, are more energy efficient.
Performance Comparison:
Inverter AC units have a much better cooling performance because, unlike non-inverter AC units, they have a variable speed compressor which gives better cooling.
Inverter AC units have a much better dehumidification performance because, unlike non-inverter AC units, they do not use resistors that generate a lot of heat thereby reducing the performance in dehumidification.
Costs Comparison:
Inverter AC units are costlier than non-inverter AC units. This is because inverter AC units have better performance and hence, are more efficient and reliable.
However, inverter AC units are cost effective as they save electricity thereby reducing the running costs in the long run.
Here, it is important to note that inverter AC units are more expensive than non-inverter AC units. However, they are cost effective because they save electricity and reduce the running costs in the long run.
