Disadvantages of inverter air conditioner


With the summer season at its peak, most of you might be thinking to buy an best 1 ton inverter ac.  Do you know the disadvantages of inverter air conditione. Reviews do not give actual knowledge about disadvantages of inverter air conditioner. We must consider many disadvantages of inverter air conditioner while buying an inverter ac.

Keep on reading this article on disadvantages of inverter air conditioner. I will tell you about things that we must consider while buying an inverter ac in India 2018, some tips to reduce electricity bill even while using inverter ac in India 2018 and a list of 10 best inverter ACs currently available in the market. So let us begin.

Window ac or a split ac?

The first question that comes to mind is whether to buy a window AC or split AC. A window AC is an AC that directly fits into the window. In window AC, all the components such as a compressor, condenser, and evaporator are in the same unit. In split AC, there are two units.

One of them is installed inside the room and another one outside the room. Here, compressor and condenser are in the unit that is installed outside the room and evaporator in the unit that is installed in the room. So according to your requirements, you can choose which one you should buy. Lets check the advantages and disadvantages of inverter air conditioner.

What is a ton?

Next thing that we look up to is the ton. Basically, what is ton? It’s a very simple concept. Lets us assume that I have installed a 1-ton ac in my room. So that 1-ton ac will give me the same amount of cooling effect that I will get from 1 ton of ice. It is that simple. So while choosing an ac of 0.5 ton, 1ton, 1.5 ton or 2 ton, you should consider the area of the room.

Best Inverter AC in India 2018: Buyers Guide

If the area of the room is 90 sq. ft. or less then you should buy 0.5-ton ac. If the area is 90 sq. ft. to 140 sq. ft. then you should buy 1-ton ac. If the area is between 140 sq. ft. and 180 sq. ft. then you should buy 1.5-ton ac. And if the area is more than 180 sq. ft. then you should buy a 2-ton ac. But here is the catch. If the room in which you want to install ac, has direct exposure to sunlight, and that room needs 1-ton ac, then instead of 1-ton ac you should buy 1.5-ton ac (a half ton more).

Inverter ac or a non-inverter ac?

Next thing is should you buy inverter ac or non-inverter ac. What’s the difference? What are the disadvantages of inverter air conditioner and non inverter ac.

Non-inverter ACs consist of a rotary compressor. So when you turn on these ACs, their compressor, from the beginning starts working with it’ 100% efficiency. When the required temperature is attained, say 25*C, the compressor stops working. And again after some time when the temperature reaches around 30*C, it starts working. This cycle goes on and on and due to this on and off process, non-inverter ACs consumes more electricity and power. 

In inverter ACs, there is a reciprocating compressor. When we turn on this compressor, initially it starts with 10%-20% of its efficiency which goes on increasing slowly to 100%. After the required temperature is attained, it again slows down to 30%-40% of its efficiency and maintains the required temperature. This consumes less power. This is the main reason behind the price difference. Inverter ACs are generally more costly than non-inverter ac. But if you are a person who needs instant cooling, then you should go for non-inverter ACs. Since they start working at 100% efficiency, you will get instant cooling.

Also, If you are a type of person who stays in the room hardly for 10 or 15 mins and most of the time you are out of the room, then you should buy non-inverter ACs. But if you are in the room for like 7-8 hours then you should buy inverter ACs. These are the disadvantages of inverter air conditioner.
power saving guide star ratings

What are star ratings for inverter ac in india 2018

Next thing is star rating. Star rating of your ac has nothing to do with the cooling effect of the ac. Your ac could be 2 stars, 3 stars, 4 stars, or 5 stars. More the number of stars, more you will save in the electricity bill.

Though 5 star inverter acs are high in price compared to others, it will save you money in long term. 

Copper coil or aluminum coil?

Also, you should keep in mind that which coil is used in the ac. Generally, there are two types, aluminum coil, and copper coil. You should always go with copper coil. It will be bit costlier, but it will be good for long run. Aluminum coil is a disadvantage of inverter air conditioner.

Also one more thing I would like to share. Inverter ACs are costlier than non-inverter ACs. But if you buy inverter ac, you will spend less amount of money as compared to non-inverter ACs. Non-inverter ACs are cheaper but you will have to spend too much on the electricity bill.

So these were all the technical terms you are supposed to know before buying an ac. Now here is the list of top 10 inverter ACs currently available in the market.

1.    Voltas 1.4 ton 3-star inverter ac (copper, 173v JZJ)

Voltas is a very trusted brand in the field of electronics. This 3-star inverter ac by voltas tops my list. This ac has some salient features which you won't be able to find them in any other ac. Currently, this is priced at 36K at Amazon. Some of its salient features are as follows;
  • 4 stage filtration
  • Unique energy efficient compressor provides steady cooling
  • Works smoothly even in fluctuating voltages
  • Instant cooling even at 52*c
  • Turbo mode cools the room instantly

7. IFB 1.5 ton 3 star inverter ac (copper, IACC18IA3TC4)

This ac is almost similar to the ACs that we’ve discussed earlier. This ac, unlike others has nothing unique within itself. This is priced at 36K on Amazon, which is again I think, the price is unjustified. This ac would’ve been an excellent buy at 32-33K.

Some of the salient features include
•    HD compressor works well in extreme conditions
•    Titanium coated evaporator repels dust and water
•    6 stage bio clean air filter for ultra cleaning and high air flow

8. Whirlpool 1.5 ton 3 star split inverter ac (aluminium, 1.5T 3D cool Eco 3SW)

As mentioned above, this ac uses aluminium coil, and earlier in the article I have already discussed why aluminium coils are inferior than copper coils. It is priced at 32 k on Amazon. Again, aluminium coil is the reason behind it’s cheap price. You will find following features in this ac;

•    3D cool technology
•    Intellisense inverter technology
•    6th sense power saver technology
•    Up to 12m long air throw
•    Stabilizer free operations

For this ac also I won’t personally and strongly recommend buying this one. Reason behind this is aluminium coil is used in place of copper coil. Which, I think is a major disadvantage of inverter air conditioner.

9. BPL 1.5 ton 3-star inverter ac (copper, A18KI3C8A)

An ac which uses a copper coil, at the price of 30K is quite unbelievable. Even though it uses a copper coil, some compromises are done while designing this ac. But the effect of those compromises will vary from person to person. Within a normal usage, it won’t affect much. It comes with the following features;

•    EER rating of 3.84
•    Smart digital display
•    Arctic breeze cooling
•    100% copper condenser

If you have a normal usage then you should definitely go for this one. This is the best ac in this price range.

Only in Amazon

10. Blue star 1 ton 3-star inverter ac (copper, BI3CNHW12NAFU)

This ac has no features that are appreciable. Like any other normal ac, this has some low-end features. Even though this is priced at 33 k at Amazon, this just a 1-ton ac. Which I think is not justified and highly overpriced.

There is no point in buying an ac for 33 k which is just 1 ton. And again, I won't recommend at all to buy this ac due to this disadvantage of inverter air conditioner. That’s all I can say.

These were my picks for some good inverter ACs available under the price limit of 40K. now I will tell you some tips, with the help of which, you will be able to save some money on the electricity bill and use your ac efficiently

Money Saving Tips on Inverter ac in India 2018: Buyers Guide

1.    The first tip is very obvious, always close all the windows and doors of the room. So that the room becomes cool faster and it will be easier for compressor too.

2.    Even if the ac is operating, turn on the ceiling fan at its normal speed. With this method, cool air of ac will reach every corner of the room quickly and the room will become cooler in short span of time.

3.    Always operate the ac In the range of 23-26*c. if the temperature of the 40*c and you turned on the ac at the temperature of 16*c, the compressor will have to work more. So always use ac at the temperature of 24*c. this is good for both, your health and ac too.

4.    Every year before you start using your ac, get it serviced by the professionals. If you use ac all year long, then every month you should clean the filter of the ac.

5.    Always use sleep mode of ac when you keep your ac turned on for all night long. Using sleep mode will be better than the normal usage.

So in this article, I have covered all the technical terms and major  disadvantages of inverter air conditioner.that you should know before buying the ac. Also, I have made a list of 10 best inverter ACs in the market. And at last, I have provided some tips to use AC efficiently and save some money on the electricity bill.
