Air-conditioned rooms have become more of a necessity than a luxury in the present time. It has become a common phenomenon for us to record new all-time high temperatures each summer. Global warming has been showing its signs, and we’re only left with modest scientific advancements like air conditioners to give us some relief while indoors.
Air conditioners take the indoor air and pass it through the evaporator for cooling. You can beat the scorching summer heat by installing either Inverter AC or Normal AC. The major difference between an Inverter and Non-Inverter AC is that an inverter air conditioner controls the speed of its compressor and they are advanced machines that use a controlled compressor. But Non-inverter air conditioners have a default compressor. Let’s have a deeper glimpse into the topic.
What is Inverter AC?
The Inverter technology is similar to the accelerator in the car. Power is supplied as per the requirements of the compressor. Here, the compressor is always turned on, but the power consumed depends on the temperature of incoming air and level set in the Thermostat. The speed and power of the compressor are adjusted appropriately.
An inverter is a device used for converting frequency. It facilitates the control of electric voltage, current, and frequency. By adjusting the power supply frequency of the compressors, we can easily vary their cooling or heating capacity.
An inverter type air conditioner is greatly advantageous in adjusting the speed of the compressor to control the refrigerant (gas) flow rate. So, we can ensure that only less amount of current and power is consumed. The major peculiarity of Inverter AC is its precise temperature control. Inverter Technology can be found in both configurations; Window AC and Split AC.
Compressors convert the gas to liquid and dispose of the hot air that has been produced. The temperature in a hall is maintained by frequently cooling the warm air, as in the case of a Regular Air conditioner. There is an inevitability of constant conversion of the refrigerant to gas and back to liquid again.
To make it happen, a compressor should be turned on. It condenses the gas to a liquid and then turns off. The amount of electricity needed to turn on and off the compressor is relatively high.
Inverter technology is the best solution to this problem, and it keeps the compressor on at all times more effectively.
Advantages and Disadvantages of Inverter AC
They are energy efficient as the compressor is not running constantly at full power. Here, a variable speed setting can be done effectively. If someone asks you is inverter AC better for home, you can easily advise them for opting it considering its energy efficiency. There are some high-end models which come with dual inverter technology, but before deciding which one to go for, you must know the difference between Dual inverter vs Single Inverter ACs.
As it uses less power, the inverter air conditioner will be much quieter than a non-inverter one. The unit operates its processes according to room temperature instead of suddenly turning on and off. So there won’t be any loud starts and stops. They are much better in functionality, flexibility, and durability.
Talking about the disadvantages of inverter air conditioner, Inverter Air conditioning systems are much more costly than non-inverters as they have higher installation and maintenance fees. Their parts are more expensive to replace so that it is difficult to afford in the case of a low budget family. You have to choose wisely, which suits you better with introspection.
What is Non-Inverter AC?
Non-Inverter AC has a fixed cooling or heating capacity with the compressor running at a fixed speed and can only control the indoor temperature by starting or stopping the compressors. The current and the power consumption of the Non-Inverter AC goes down when the operation stops, but as soon as it restarts it goes up sharply, thereby consuming high power compared to inverter ac power consumption. It also causes a lag and takes some time to reach the previous room temperature. So, therefore, Inverters AC is more comfortable and energy saving compared to Non-Inverter AC.
Advantages and Disadvantages of Non-Inverter AC
Non- inverter AC is affordable and accessible. They are often suggested over the inverter air conditioner because of the low price.
There are a lot of disadvantages to Non-Inverter AC. They have been developed in such a way that we have to turn on and off every time, and this increases the probability of wear and tear. When a certain temperature is attained, it may result in noise pollution. Compared to the inverter AC, they have a shorter lifespan. Mismanagement of the air conditioning system may lead to high electricity bills. Non-inverter AC is good for those users who don’t use Air Conditioner regularly.
Inverter AC vs Normal AC: The Real Difference
Below factors are considered when talking about the difference between inverter and non-inverter AC.
If we compare the cost of Non-inverter air conditioners against an inverter air conditioner, we may select Non-inverter AC as they are cheaper and affordable to everyone. The major disadvantages of inverter air conditioner are the humongous Price needed for its installation. But If you invest some more money in an inverter type, it will provide a long-lasting benefit as it has an advanced design and versatility. Energy savings can be done effectively with the inverter type air conditioner compared to the non-inverter type air conditioner. It may benefit you save up to a maximum of 50% in your electricity bills.

2. Energy consumption
We can analyse the power consumption of Air conditioners of various tonnage and star ratings based on the data obtained from BEE in 2018 (the levels haven’t changed in 2021).
E.g., For 0.75 tonnage, 1-star non-inverter AC (627 watts) consumes more power compared to 2 stars AC,3 Star AC, 4 Star, and 5 Star AC. When the tonnage increases, power consumption also increases. 5-star AC is purely inverter type. That’s why it consumes less energy compared to others. Three stars AC is a mix of both inverter and non-inverter types, consuming moderate power.
3. Noise Emitted
A non-inverter AC makes ample noise because the compressor unit constantly requires to be turned on and off.
But in the case of an Inverter AC, there is no need for the compressor to be turned on and off. The noiseless operation makes it a more promising one as it won’t perturb the sleep of the inhabitants. Noisy operation results in the deterioration of the system, thereby increasing the maintenance costs. So, an Inverter Ac is better than the latter.
Regular Air conditioners are of fixed size. So, it’s difficult to occupy the smaller space if they have higher dimensions than that of the area. But the inverter technology is said to have surpassed this limit because of its flexibility. It can adjust to any space. That’s why Regular Air Conditioners are less preferred as they don’t have a speed /variable tonnage facility. They have single compressors and single tonnage. Inverter AC is more flexible with the load. If you are looking for options in Inverter AC, you can check this page for the Best Inverter AC available in the market.
Whenever I think about the performance of Air conditioners, the First and basic question that arises is “Which Ac cools down the room faster?”
Both of them cool down the room at a balanced rate, but the inverter AC cools down the room faster. The non-inverter may blow the cool air. But an Inverter AC focuses more on controlling the temperature of the room rather than cooling \heating it. That’s why an inverter AC cools down the room faster than a non-inverter AC. A simple BEE 3-star inverter AC can save as high as 7% of energy compared to that of a BEE 5-star normal split AC.
Inverter AC possesses a variable frequency motor that frequently adjusts its speed according to the cooling requirements of the occupants. In the case of a Non-inverter AC, it has a compressor motor with a fixed start and stops cycles. Due to this, energy consumption will be much more. The major peculiarity of Inverter AC is that it comes with a wide range of air filters such as carbon, HEPA, BLU, etc. whereas non-inverter AC owns standard air filters.
The inverter air conditioner is a better adaptable, flexible unit due to the regulated compressor system. It has the potential to adapt to the temperature setting of the room and will adjust its operations based on the sensing of the thermostat. So, they have proved their worth in terms of performance.
On the contrary, non-inverter air conditioners operate on a (fixed) level of cooling power. Before buying an AC, you must consider all the aspects along with the area of necessity, economic aspects, lifespan, etc. Get familiar with different dimensions of both Air conditioners and select the best option available.
Inverter AC vs Non-Inverter AC: Which is best for you?
It all depends on the user to user. Still, we recommend you to use Inverter AC as the Inverter air conditioner is more suitable for one’s house if the duration of the operation is greater than 4 hrs per day. For lesser usage duration, a Non-Inverter air conditioner would be a more suitable choice. Inverter AC won’t take up much power just like the Non-inverter AC with peak power requirements. It has the competence to adjust its capacity based on the requirement of the room and cooling rates.
