What are The Advantages and Disadvantages of an Inverter AC?

05-04 2023

They say - “Air conditioning is the ultimate multitasker, keeping you cool and your power bill high.” While it's true that inverter ACs are well-known for their energy efficiency, it's also important to note that like any other appliance, they require regular maintenance and care to perform optimally.

So if you're in the market for an inverter air conditioner and want to weigh its pros and cons before actually buying it, you’ve come to the right place! In this blog, we’ll explore the benefits and drawbacks of using an inverter AC, as well as some personal insights to help you make that final purchase decision! 

I am certain that while browsing through the air conditioner section, you have come across words like “motor speed’, “cooling performance”, “energy savings”, etc. I know all these terminologies can get a little confusing. So let’s first have a look at the working mechanism of an inverter AC and what these terms actually mean - 

What is the mechanism of an Inverter AC?

Let me begin by explaining to you what an inverter AC is. It is an energy-efficient air conditioner that works by controlling the motor speed, eliminating wasteful operation, and making it quieter. So, instead of turning on and off repeatedly, it runs continuously - adjusting the motor's speed to match the desired temperature.

Is the Inverter Technology in AC worth it?

As the inverter ACs operate at varying speeds to maintain a constant room temperature, they consume less power than conventional ACs. This results in giving you comfort without wasting energy and your hard-earned money.

I personally feel investing in inverter technology is worth it if you prioritize energy savings, durability, and better cooling performance. While inverter ACs may cost more upfront, it undoubtedly saves you a lot of money in the long run.

Advantages and Disadvantages of Inverter AC

That is, although inverter ACs have gained popularity due to their efficiency and numerous other benefits, there are some obvious disadvantages attached to this 21st-century air conditioner - Inverter AC. So let’s dive into the main discussion of today’s blog:


Key Points


Increased energy efficiency

The compressor present in inverter ACs has variable speed. That is the motor does not turn ON/OFF continuously but rather runs at a consistent speed. This results in lower consumption of energy.

Lower electricity bill

The energy efficiency nature of inverter ACs ultimately results in cost-effectiveness. Since the power consumption is low, the energy cost also lowers proportionately.

Improved cooling

The compressor not only runs at a variable speed but also at a much higher speed compared to the fixed speed of conventional air conditioners. Hence, it cools a room in no time.

Quieter operation

Inverter ACs operate almost in silence due to the compressor eliminating all wasteful operations. Besides, the compressor also runs at a much lower speed compared to conventional air conditioners.

Solar power compatibility

To power air conditioners with solar energy, an inverter is required to convert DC current from the solar panels to AC current. Solar-powered or inverter AC then utilizes the energy stored in a battery after passing through the built-in inverter.

Stable voltage level

No voltage fluctuations occur when the compressor turns ON/OFF, unlike non-inverter ACs. This is because the compressor in an inverter AC starts gradually and runs continuously at a low speed, maintaining a stable voltage. 

Lower carbon footprint

Inverter ACs use more efficient and green refrigerants such as the R32, which leaves a lower carbon footprint on the environment aside from having a better cooling capacity. 


Key Points


Poor insulation costs

Energy and cost efficiency of inverter AC is subject to the room being properly insulated. If the room where the inverter AC is operating is not properly insulated, power consumption rather increases along with the electricity bill.

High humidity

If the capacity of your inverter AC is substantially more than what’s required for the room, then your AC will run frequent short cycles to maintain the room temperature. This change in temperature does not dehumidify the air, ultimately leaving you feeling uncomfortable.

High-priced investment

Despite having higher life expectancy and lower operational costs, inverter ACs have a much higher purchase price due to the more complex design of their advanced compressor.

Repair and maintenance

It is expensive to replace or repair the components of inverter ACs as they are more intricate in design and not that easily available. 

Limited options

There is a scarcity of models of inverter ACs compared to non-inverter ones due to the technology being relatively new in the market. As a result, customers often face difficulty finding the right model that fits their needs and budget. 

In a Word!

Undoubtedly, air conditioners are the superheroes that are saving the day against this scorching summer heat. However, there is nothing wrong with making an informed decision regarding whether or not to buy an inverter AC. In my opinion, the pros of using an inverter AC long outweigh its cons, if chosen the right one! 

Here, at Haier Bangladesh, we have a wide range of air conditioners, which not only offer the benefits of an inverter AC but also eliminate most of its disadvantages. So, what are you waiting for, check out the perfect Haier for your room and budget today.

Frequently Asked Questions (FAQs)

  • Why are inverter air conditioners better?

Inverter ACs adjust temperature by changing motor speed, without turning the motor ON and OFF. This saves energy and reduces power loss.

  • How much energy does an inverter AC save?

Approximately 20-40% more energy than non-inverter ACs.

  • What is the disadvantage of inverter AC?

It is more expensive compared to the normal ones.

  • What is the difference between an inverter and a non-inverter AC stabilizer?

Non-inverter ACs need a stabilizer whereas inverter ACs do not - as they operate on variable voltage.

  • How often should you service an inverter air conditioner?

Once every 12 months.
