Inverter AC vs Non-Inverter AC: Which One is Right for You?

02-12 2023

As the summer heat starts to rise, many of us consider getting an air conditioner installed to keep our homes and offices cool and comfortable. But, as we all know, air conditioners can be a significant source of energy consumption, are costly, and also leave a carbon footprint. With this in mind, it is important to assess not just the comfort and convenience provided by an air conditioner, but also its energy efficiency and environmental friendliness!

When you consider buying the best AC in Bangladesh, you’ll have two options to choose from, inverter and non-inverter. Both of these types have unique features and operate differently. When you’re choosing one for your space, you’ll have to keep your preferences and budget in mind.

Inverter air conditioners are well-known for their energy efficiency, temperature stability, silent operation, extended lifespan, and for its eco-friendliness. However, they can be more expensive upfront than non-inverter air conditioners. Non-inverter air conditioners are less expensive up front, but they are less energy efficient and have a shorter lifespan. They can also produce increased temperature fluctuations and noises.

In this blog, we will be discussing the pros and cons of both types of air conditioners, and help you determine which one is right for you and the environment– because it's important to be in sync and balanced with the environment to live a healthy life.

What is an Inverter and Non-Inverter Air Conditioner?

An inverter air conditioner is a type of air conditioner that controls the speed of the compressor with an inverter rather than turning it on and off to maintain the desired temperature. This enables the inverter air conditioner to operate at a lower speed and consumes less electricity, resulting in significant energy savings.

In comparison, non-inverter air conditioners feature a traditional on/off compressor system and are less energy efficient.

Inverter AC units are generally more expensive than non-inverter AC units, but they can be more cost-effective in the long run due to their energy efficiency. They also tend to be quieter and more stable in temperature control.

How Does an Inverter Air Conditioner Work?

An inverter air conditioner uses a mechanism known as variable-frequency drive (VFD) to control the speed of the compressor. VFD allows the AC to adjust the compressor speed to match the cooling requirements of your living space, office spaces or rooms. When the room is cool, the compressor runs at a lower speed. However, as the room gets warmer, the compressor’s speed increases. In essence, providing a more precise temperature control, and a more stable room temperature. Additionally, the compressor of an Inverter AC unit makes less noise, minimizing noise pollution as well.

According to a SpringerLink article, the inverter AC saves up to 44% of energy usage when compared to a non-inverter of 3471 kWh/year and 6230 kWh/year, respectively. Furthermore, according to the Total Equivalent Warming Impact (TEWI) analysis, inverters can save 49% of CO2 emissions.

Inverter air conditioners include an inverter technology, which regulates the amount of power consumed by the AC, resulting in energy efficiency and cheaper electricity bills. Who wouldn't desire an AC that keeps you cool with smart innovation and reduces carbon footprint while also lowering the utility costs?

What factors to consider when choosing between the two types of Air Conditioner for my space?

There are several factors to consider, let’s look at some points given below for a more clear understanding:

01. Size of the space: The size of the room or area to be cooled is an important consideration. Larger areas may require a larger capacity air conditioner, in which case an inverter air conditioner is more efficient.

02. Energy efficiency: Inverter air conditioners are often more energy efficient than non-inverter air conditioners, which can save you money on your utility bills in the long run. Therefore, it is ensured by the best AC companies to give you value for money.

03. Temperature stability: Inverter air conditioners are able to maintain a more consistent temperature, whereas non-inverter air conditioners can cause temperature fluctuations.

04. Noise level: Inverter air conditioners are generally quieter than non-inverter Air Conditioners.

05. Upfront cost: Non-inverter air conditioners are less expensive upfront, but inverter air conditioners are more cost-effective in the long term due to their energy efficiency– making it a wise investment.

06. Lifespan: Inverter air conditioners often last longer than non-inverter air conditioners. Thus, having a longer lifespan.

07. Environmental impact: Inverter air conditioners are considered to be more environmentally friendly than non-inverter air conditioners because they use less energy and produce less greenhouse gas emissions.

08. Maintenance: Inverter air conditioners need less maintenance and repairs than non-inverter air conditioners.

Pros & Cons of the Two Types of Air Conditioners:

The table below compares the benefits and drawbacks of inverter and non-inverter air conditioners. However, it's always a smart option to consult with a professional to ensure you're getting the finest solution for your individual needs and budget.

Which AC Should You Buy for Your Space?

Consider the comparative discussions between the two types, so when deciding between an inverter and a non-inverter air conditioner, consider the size of the room or area to be cooled, your budget, and the amount of time you intend to use the air conditioner. If you want to use the air conditioner regularly or for extended periods of time, an inverter air conditioner may be a preferable option.

It's also vital to consider the eco-friendliness of Inverter ACs over Non-Inverter ACs because they use less energy, meaning less electricity bills, and hence emit less emissions. A Non-Inverter Air Conditioner, on the other hand, maybe a more cost-effective option if you expect to use the AC occasionally or for shorter periods of time.


Air Conditioners have become a necessity in recent times for everyone. The availability of options and brands has made it easier for everyone to have the comfort that can be generated by an AC. However, considering the discussed points above, it is best to assess before purchasing any machines or technologies for yourself.

Buying an Air Conditioner is a long-term investment, therefore, you need to choose the Best AC Brand in Bangladesh to ensure that your purchase has been worth it.

Frequently Asked Questions (FAQs)

01. How long does an Inverter AC last compared to a Non-Inverter AC?

Inverter ACs typically have a longer lifespan compared to Non-Inverter ACs.

02. Can I use an inverter air conditioner in a large room?

If you want a long-term, energy-efficient device, choosing an inverter AC is always a good idea, regardless of the initial high cost. However, if you have large rooms to cool and don't want to spend a lot of money, non-inverter AC is the way to go.

03. Is it better to undersize or oversize AC?

While the capacity of an air conditioner normally corresponds to its energy consumption, an undersized air conditioner would require more electricity simply because it is likely to run continually, barely stopping for breath.

04. Can I control an inverter air conditioner remotely with a smart device?

Yes, some inverter air conditioners can be controlled remotely with a smart device such as a smartphone or tablet, only if the device has that feature.
