Air Conditioner Buying Guide 2026

Selecting right AC for you is not a big task. Let’s first have a quick look at the Frequently used AC terminology. Then you will be able to decide which AC is best for you.

Ton: ACs are available in various capacities via .75 Ton, 1 Ton, 1.5 Ton  or 2 Ton air conditioner. ‘Ton’ refers to the amount of heat removed by that ac per hour. Therefore higher the Tons, higher capacity to cool large area. You can know which capacity AC will be perfect for your room size from the following info graphics.

• .75 Ton AC is good for your bedroom size below 80 square feet area.
• 1 Ton AC is for your room size upto 120 square feet.
• 1.5 Ton is good enough upto 190 square feet area.
• 2 Ton is ideal for living room etc area above 190 square feet.

Note: In case you live above third floor or windows more that 25 Sq Ft or sunlight falls on your wall directly then you should increase your room area by 50% then calculate AC capacity for your room.

What is Energy Star?

Energy star of any AC define its energy efficiency. These are stranded set by the BEE. Energy star starts from 1 – 5.  1 Star AC,  2 Star AC,  3 Star AC,  4 Star AC and 5 Star AC. Higher the energy star, greater the energy efficiency. A BEE label looks like following picture.

Update: Energy Rating: 3 Star (2018). Note that as per Bureau of Energy Efficiency (BEE), there is a 2 point energy rating drop in 2018 for non-inverter split ACs. E.g. a 2017 5 star non-inverter split AC will become 3 star in 2018.

What is Refrigerant

A refrigerant is a liquid or gas that is used in air conditioners and refrigerators to through out heat out in the atmosphere. Without refrigerant, the freezing technology is not possible.

Which Gas is Used in Air Conditioner

There are many refrigerants that are used in air conditioners. Few ac gases names are R-22, R-410A, R-32 and R-290. Few refrigerants are harmful to the environment and cause Global Warming. Below table describes the data for Global Warming Potential of various refrigerants.

R-22 has Ozone depletion potential. Don’t buy AC having R-22 refrigerant. R-410A, R-32 and R-134A have high global warming potential. The most environment friendly refrigerant available in Indian market are R-290 and R-600A.

Most of the refrigerators in India market using R-600A. Due to energy efficiency and least Global warming potential you should go for air conditioner having R-290 and if you buying refrigerator the R-600A.

Importance of Coils in air conditioners

Core of air conditioning is refrigerant gas that converts into gaseous state to liquid state by compression and the back to gas state by absorbing heat of the room. A refrigeration process has following four steps.

In air conditioning heat from the inside air is transferred to outside environment. This transfer of heat takes place in the coils.

Refrigerant in the evaporation coils evaporates by absorbing the heat of room. Air cooled in this process is directed into the room. In this process gaseous refrigerant is passed through the compression process and condensation coils where the refrigerant condenses by releasing the heat into the surrounding environment. There are two types of coils in air conditioners: Copper coils and Aluminium coils.

Copper coils vs Aluminium coils: Which one is better?

Copper coil condenser based air conditioners are very popular these days. They provide better heat exchange. Although they are cost little higher. The main reason is that copper coil based AC giver better cooling, it requires low maintenance and long lasting.

Aluminium coils are cheap as compared to copper. But aluminium coils are difficult to repair so they are replaced when damaged. So if your are buying AC for longer time its better to invest little more today, buy a copper coil based air conditioner and enjoy for years. Following is the comparison table between Copper coil and Aluminium coil.

Latest Technology is Air conditioning 

Blue Fin Condensers

Both copper and aluminium coil can corrode. It is very important to protect coils from corrosion because it damages the coils and results in leakage. Corrosion is high for people who live near to sea shore or climate is humid with moisture content in the air.

If you live in such areas then you should buy AC that has pre coated coil with Anti-Corrosive material. Another name of this feature is Blue fin condenser. This technique is used by Voltas, Panasonic, O general, Blue star etc.

Micro Channels

Micro channel or Multi-Jet is another popular Anti-Corrosive technology. This set up consists of flat tubes and aluminium fins located in between tubes and two refrigerant manifolds. There is no galvanic corrosion. This techniques is very useful for people living in coastal areas and corrosion prone areas.

Inverter Air conditioner

This technology was invented in Japan. This technology is available only in split ACs. An Inverter AC is just like a car with gear box and accelerator. In this technology compressor consumes power according to its need (Less or More). The compressor is always on but it consumes more or less power depending upon the temperature set by the user and the temperature of incoming air.

Benefits of Inverter Air conditioner

• At least 30% – 50% cheaper to run as it consumes less power
• AC start up time is reduced by 30%
• It is far quicker to achieve desired temperature
• It is much quieter
• No voltage peaks from compressor
• In Inverter AC there is No temperature fluctuations. So it maximize comfort level

What is difference between Inverter and Non Inverter air conditioner?

Inverter ACs are popular because it consumes less energy as compared to normal AC. An inverter AC is more energy efficient than normal AC. The basic principle of AC is to achieve targeted temperature set by the user. In normal ACs condenser starts cooling and when target temperature is achieved then it switch off. After some time when temperature increases it switch on again with full capacity. This switch on and off process continues.

The inverter AC work differently. When target temperature is achieved then it does not switch off but it reduces the cooling/speed. Now its aim is to only maintains the target temperature. In this stage it consumes only 25 to 30 percentage of the total electricity this results in huge saving on electricity bills.

In a Non Inverter air conditioner condenser takes a fixed amount of power and works on a fixed speed. It means that it has to start and stop to maintain targeted temperature set by the user.

LG Dual Inverter AC

LG, one of the top 10 companies in manufacturing electronic machines, designed the Dual Inverter AC with 1.5T cooling. It has many features like dual inverter, active energy control, a micro dust protection filter, and monsoon comfort. LG dual inverter ac 1.5 ton price around Rs. 47,990. It has 10 years warranty.

It solves the problems like improper cooling, noise problems, etc, and makes the room cools faster, lasts longer, and runs quieter.

What is the difference between Dual Inverter AC and Inverter AC?

LG Inverter AC consists of two rotors helps to cool fast, saving energy, low noise, and greater stability. Whereas, Dual Inverter AC can save 834 units with respect to a 5-star Split AC in one year, which helps the user to save more energy.

Advantages of Dual Inverter AC

Some common features of air conditioners

Here is short description (what & how) about common features of air conditioner.

Anti bacteria filter

It makes the room environment refreshing. This is an inbuilt filter that removes invisible substance like dust , pollen, bacteria and other allergens. This filter helps in increasing the lifetime of AC by avoiding dust mite deposits on the internal part of AC.

Dust filter
This filter avoids dust mites evaporate at home. Dust particles stick to these filters. It is advisable to clean these filters with plain water once in a month or according to usage for better performance.

Room heater
It is for use in winter. No need to buy a room heater in winter.

Dehumidifier
Get rid of excess moisture in the air during the moonson season with this feature. In spring and fall room covers with high level of moisture and cause seating, stickness and makes bacteria growing environment. Dehumidifier allows to remove excess moisture from the room and gives comfortable feeling.

Auto clean fiction
Auto clean function avoids bacteria formation in the internal parts of AC. This increase AC life and cooling functionality.

Auto detect
AC stores user’s preferred temperature settings in his memory and adjust temperature itself to change in outside temperature or humidity. Nowadays few advanced technology AC detects the number of peoples in the room and adjust cooling temperature.

Sleep mode

Sleep mode reduce cooling every hour and saves your electricity bills. This feature is very useful in condition where the outside temperature drops considerably in the middle of night.
