Best AC in India 2021 – Which AC Do You Need? (Buyer Guide)

 This is the most important question you should ask yourself before reading any further.  Air conditioners don’t come cheap and you don’t buy a new AC every next year like your mobile handset. So, its important that you buy a great machine that remains good for years to come and meets requirement of your family not just on regular days but also during small family gatherings.

1 Ton, 1.5 Ton or 2 Ton Air Conditioner?

This can also be measured in terms of BTU by calculating area of a room in sq. ft. and then multiplying it with 30 or with 40 if your room is at top floor and exposed to sunlight from roof or from more than two sides. The number of windows, area of windows, max summer temperature in your city, no of people occupying room, ceiling height, heat emitting appliances in room, and lots of other factors affects the BTU calculations.

Important Note: When calculating BTU for your room, add 600 BTUs for every additional person that is expected to be in the room. Also add 10 percent more BTUs if room is sunny or if your city temperature goes above 40°C in summers.

Once you have calculated the BTU required for your room, compare it with BTU power supplied by different air conditioners as given in table below and then decide the capacity required for your AC.

Power of 1 ton, 1.5 ton and 2 ton AC

AC Capacity (tons)	Power (BTU/hr)
1 Ton AC	12000 BTU/hr
1.5 Ton AC	18000 BTU/hr
2 Ton AC	24000 BTU/hr

If that calculation is tough for you (It actually is), then refer to the simplified information below:

Inverter AC, or Normal AC- Which one is Better?

 In short, go for an Inverter AC.  Don’t fall for low upfront cost, discounts, or freebies. Inverter ACs are more comfortable, highly durable, and last longer that the non invertr air conditioners.

If you buy a 5 star inverter AC, it will save you more money than its cost over a span of 10 years.

Pro Tip: On an average, an AC uses 350-700 units a month (for 12 hours of use daily) costing you ₹1800 to ₹4500 per month in electricity bills in all major cities of India. With an Inverter AC, this cost comes down significantly.

Whats so special about Inverter AC?

An inverter type air-conditioner operates at constant speed after achieving desired indoor temperature so that the temperature never goes up again.  Whereas in ordinary AC, compressor turns off after achieving desired indoor temperature and turns on again when temperature goes up.

Non-inverter air-conditioners stops and starts repeatedly. A 1.5 ton inverter AC would work at 0.3 to 1.7 ton power based on cooling requirement. As a result, inverter air conditioners are more energy-saving and comfortable than non-inverter air-conditioners.

See the Diagram below for better understanding:-

BEE Ratings: 2 Star, 3 Star, 4 Star or 5 Star Rated AC – How much of a difference does it make?

Air conditioners are given energy star ratings by the BEE – Bureau of energy efficiency. More the number of stars, more is the energy efficiency of the appliance. The available stars are between a minimum of one and a maximum of five.

An AC with a 5 star BEE ratings save you upto 20 to 40 % in electricity bills when compared to a 1 star AC. Therefore, it makes sense to pay some extra money and purchase an AC with 4 to 5 star energy rating, as it will save you much more money in the long term.

Split AC, Window AC, Portable AC, or Cassette AC

Portable air conditioners, and Cassette air conditioners are not very popular in India. You can find cassette air conditioners in showrooms, or offices but very rarely someone purchases them for their home. Portable air conditioners are even more unpopular.

The remaining two types of air conditioners are very popular. And making a choice between these two is relatively easier. As far as efficiency is concerned, there is no difference. Both are equally good at cooling a room. However, the window air conditioners usually consume more electricity than their counterparts.

Lets look at pros and cons of a window AC and a split AC.

Now that we know the pros and cons of window and split AC, it should be easier for you to make a final decision on the type of best air conditioner to buy.  We recommend going for a split AC but purchasing a windows AC in not a bad idea either.

Type of Compressor & Condenser

If you are looking for comfort and efficiency, you would want your AC to be less noisy, and capable to maintaining a constant indoor temperature. You can achieve this by preferring an AC with Inverter compressor over those that come with a simple rotary type compressor or reciprocating compressor.

Inverter Compressor

Actually, inverter compressor is also a type of rotary compressor. The only difference is that it has a DC inverter to control the speed of the compressor according to the cooling requirement. In such air conditioners, the compressor never shuts off completely. This results in less wear and tear to the parts, stable room temperature, no sharp fluctuations in current, and overall quieter operation.

MCHE or PFC Condensers

When it comes to the efficiency of condenser, MCHE (Microchannel heat exchange) condensers made of e-coated aluminium alloy is the best.

The MCHE coil construction provides for excellent heat transfer due to the enhanced surface area and the metallurgical bond between tube and fin. Air conditioners with MCHE coil will cool the rooms much quickly and will be capable of cooling rooms in cities that see temperatures soaring above 45 degree Celsius.

When MCHE is used as a condenser in an air-conditioning unit, it is commonly called a Parallel Flow Condenser (PFC).

However, these condensers are susceptible to corrosion, hard to clean, and hard to repair.

RTPF Aluminium-Fin-Copper-Tube Condensers

RTPF (Round Tube Plate Fin) heat exchanger, made of aluminum fin and copper tube condenser coil, are the most common type of condensers used by air conditioners in India. Such heat exchanger are are not as efficient as the MCHE condensers but are not bad either.

Also, one major advantage of these copper tubes is that they are repairable but the aluminium condensers would more likely need to be replaced when damaged.

For its lower maintenance cost, corrosion resistance, and durability, copper tube-aluminium fin condenser is our choice for condensers. The latest condensers of this type are also high in efficiency with the use of grooved copper tubes and dual inverter compressor.

Durability of Air Conditioner

While durability of any appliance is very important, it is even more important when it comes to purchasing an AC, especially for the people staying closer to coastal areas.

If you live near the coast, your air conditioner is a lot more susceptible to damage from the surrounding salty and humid air. If not protected, your air conditioner body will rust and condenser coil will suffer corrosion, resulting in cooling gas/refrigerant leak. This would lead to premature repair or replacement of broken parts due to galvanisation and salt corrosion.

To avoid such situation, you must purchase a AC that comes with some kind of hydophillic coating on condenser and evaporator. Such coatings don’t let water to stick to the coil or fins and therefore prevent corrosion.

Such coatings are known by different names like bluefin coating or goldfin coating, or titanium dioxide coating. Whether, you have a copper-tube-aluminum-fin condenser, or a MCHE condenser made of aluminium alloy, it should always come with a cathodic e-coating of some hydrophillic material like epoxy, etc. This is a must for longer life of your AC.

Also read our post on how you can prevent coil corrosion and refrigerant leak in air conditioners.

Type of Refrigerant Gas

Most customers will not care about this factor and the sales men at showroom will also not care to mention this aspect of air conditioners. However, it still makes a difference, not just in performance but also in future serviceability and cost of maintainance of your air conditioner.

If you have an old AC at your home, it will probably have R-22 refrigerant in it. While it works great for cooling performance but when leaked into atmosphere, it contributes to the depletion of ozone layer. This was a real problem for safety of enviornment and governments in several countries including Indian Government has therefore banned its use. Needless to say, you should avoid purchasing new AC that comes with R-22 gas.

Another type of refrigerant is R410. This is used by a few brands like Daikin in India. However, it is also being phased-down for the same reason as R-22 refrigerant.

Finally, the latest refrigerant that is safest among all and is widely used in India now is R32. It  is a better choice for the environment and reduces electricity consumption up to approximately 10% when compared to that of air conditioners using R-22 gas.

For detailed information about refrigerant gases, read our post on Why AC Manufacturers Are Switching Over to R32 Refrigerant?

Brand and Service Availability

When purchasing expensive appliances like air conditioners, its important to limit your choices to brands that have their own service centers in your area. For example, O’General air conditioners are great when it comes to the quality but when we talk about service availability, it is limited to only a few select cities in India. Then there are brands launched by e-commerce companies that sell for very cheap cost but offer poor after sales service. One must avoid such brands, particularly when there are better options available from brands like LG, Panasonic, Sanyo,  Voltas, Hitachi, and Diakin.
