We all know that during summer, the days can get unbearably hot. After a long day in the sun, we want to come home to a chilly house, and what better way to do it than to ensure that your home is fully fitted with top-of-the-line, most energy-efficient inverter air conditioner that will be friendly with your energy bill.

But the inverter AC stands out as the most energy-efficient presently. Now, there are many factors to consider before finding the most energy-efficient inverter air conditioner, such as efficiency, energy saving, noise, etc. Luckily for you, we’re here to do the job.

In summary, an inverter air conditioning system can alter its power output to maintain precise room temperature. It reaches the temperature you want by increasing its compressor operating frequency. When achieved, it adjusts the compressor rotation speed to maintain that temperature without using too much power. It combines high intensity and efficiency, keeping your home at your desired temperature.

Does inverter ac really save electricity?

YES! We call it power saving air conditioner!

Inverter technology is an innovative method that has to do with the electromotor of the compressor. The inverter increases the compressor operating frequency to reach the desired temperature rapidly. When this has been attained, it adjusts the frequency to maintain the temperature without consuming excess power efficiently. It runs at total capacity to achieve the desired temperature; then runs at part load to retain it, thereby using less energy than a non-inverter AC.

An inverter air conditioner never turns off its compressor; instead, it adjusts the load according to the room’s temperature. This means it doesn’t run at full power, which makes it a more energy-saving appliance than a non-inverter air conditioner.

The continuous running of the compressor in an inverter AC means it can function for longer, and it is also able to maintain the temperature of a room with more efficiency than regular air conditioners. An inverter air conditioner can reach the desired temperature up to 25% faster than traditional air conditioners. An inverter air conditioner can save up to 40% of power, saving you considerable money on electricity bills.

Inverter aircon vs. non inverter power consumption

Non inverter air conditioners run on compressors that go on and off while maintaining the temperature of a room. The compressors run on full power to reach the desired temperature. When this is achieved, they go off until the temperature falls a few degrees, then they turn back on to get around the original temperature, on full power.

The non inverter air conditioners run on the AC system, which uses more energy than the DC system. As shown above, the Inverter air conditioner runs at a comfortable temperature by auto-adjusting itself immediately after reaching the habitable zone.

Inverter aircon vs. non inverter aircon

  • Energy efficiency

In a non inverter AC, you can hear the compressors on/off the sound. Whenever it starts, it draws most of the power, and it runs on that power until the temperature is achieved. This results in higher consumption of energy. Meanwhile, an inverter AC converts the AC’s input power to DC power to adjust the frequency according to the load of the room. This makes it a more energy-saving choice

  • Noise

Due to the on/off sound of the compressor, non inverter air conditioners tend to become quite noisy. This problem is not faced when using an inverter AC because the constant running of the compressor doesn’t disturb your quiet.

  • Faster cooling

A non inverter air conditioner has a fixed speed of air conditioning. It delivers a fixed amount of temperature to maintain the required room temperature. This is not the same when using inverter air conditioning. An inverter air conditioner provides precise cooling in a very short time. This can vary according to the time of day, room size, season, etc.

  • Temperature

In a non inverter air conditioner, when the set temperature is achieved, the compressor goes off. It comes back on when the temperature falls by a few degrees. This causes fluctuations in room temperature. The inverter AC, on the other hand, has a compressor that adjusts its motor rotation speed to maintain the set temperature, ensuring a standard temperature.

  • Durability

One of the top reasons to choose an inverter AC is its durability. The compressor lasts longer than a non inverter air conditioner because of its smooth running without constant fluctuations.

Although Inverter air conditioners generally cost more, they are worth their cost.

How much electricity does an inverter air conditioner use?

You need to know a few things about the electric energy consumption of Air conditioners. Generally, the energy star rating in BEE (Bureau of energy efficiency), i.e., the 5-star rating of an electrical appliance, is determined by the energy consumption and size of the product.

As for the Air conditioners, their energy stars depend on the efficiency of that appliance’s cooling/heating capacity per unit of energy it consumes.

The BEE 5-star rated non-inverter ACs are considered the most energy efficient in the line. However, a BEE 3-star rated inverter AC is more energy efficient than a BEE 5-star rated non inverter AC.


A 5-star rated non inverter AC of 0.75 tons consumes 576 units of power in 1600 hours, while a 3-star rated inverter AC of the same capacity consumes 550 units of energy in 1600 hours.

The A 5-star rated non inverter AC of 1 ton consumes 760 units of power in 1600 hours, while a 3-star rated inverter AC of the same capacity consumes 726 units in 1600 hours.

A 5-star rated non inverter AC of 2 tons consumes 1412 power units in 1600 hours, while a 3-star rated inverter AC of the same capacity consumes 1005 units in the same timeframe.

Based on this information, the higher efficiency inverter ACs have a lower power consumption. Inverter ACs are the top choice for anyone looking to buy an air conditioner because they are more energy-saving and good for the environment.

Considerations for most energy efficient inverter air conditioner

  • Energy efficiency

Energy efficiency is measured by SEER rating. ACs with a higher SEER rating are generally more energy efficient than others. Inverter ACs for home use usually have a SEER value of 14 to 22. Your SEER rating should depend on your location and environment.

  • Quiet operation

Inverter ACs are the quietest ACs so far due to the constant and smooth working of the compressor. Many inverter air conditioners have whisper operation that allows them to be as inconspicuous as possible; you almost forget they’re there.

  • Heating and Dehumidification

An AC with heating and dehumidification properties can save you time, work, and money. Not every AC comes as a 3-in-1 unit, so checking first gives you an idea of what you’re getting.

  • Durability

In general, inverter ACs are expected to last longer than non-inverter ACs. A lot of them can last up to 5 years. This is very important as you wouldn’t want to shop for a new AC soon after getting one. Proper maintenance of your system plays a role in the long life of your system.
