Find the Right AC Has Never Been Easier
Below are the top 6 things you need to know before Buying an AC
- Window AC vs Split AC
- Room Size
- Energy Star Rating
- Aluminum or Copper Coil
- Inverter or None-Inverter
- Spacial Future
Window AC vs Split AC
While split ACs are priced slightly higher than window ACs, the below table compares them on key parameters
Apart from the room sizes mentioned below, a few factors that might require you to select a higher capacity unit have been mentioned below
- Multiple windows: If the room has multiple or large windows.
- Floor: If your house is located on the top floor or is higher than the 3rd floor.
- Room Temperature: If the normal temperature of the room is above 40 degrees C.
- Facing: If the AC is facing west or south
1. Small Rooms
Small Rooms Up to 120 sq.ft, Upto 1.2 Ton ACs suitable for study rooms, small bedrooms.
Choose AC Tonnage According to These Room Sizes
- 8 x 10 feet room size = 0.8 ton AC
- 10 x 10 feet room size = 1 ton AC
- 12 x 15 feet room size = 1.2 ton AC
- 14 x 15 feet room size = 1.5 ton AC
- 20 x 20 feet room size = 2 ton AC
2. Mid Size Rooms
Mid size rooms 121 to 179 sq-ft, 1.2 – 1.7 Ton ACs suitable for bigger bedrooms
3. Large Rooms
Large rooms 180 sq.ft above, 1.8 Ton & above ACs suitable for big living rooms.
Energy Star Rating
The Bureau of Energy Efficiency (BEE) has a star rating methodology called indian se Seasonal Energy Efficiency Ratio (ISEER) for air conditioners.
ACs with higher star ratings will consume much less power, thereby saving money on your electricity bill in the long run.
Energy Star Rating Table-
Higher star rating cost a bit more initially but consume much less power, and hence save money on your electricity bill in the long run. Compressor material in the AC also contributes to energy consumption. Compressors made of copper are more energy-efficient than aluminum ones.
Below are estimated calculations on power consumption for a 1.5-ton capacity AC. Values will vary for other capacity & ISEER rating combinations.
|Star||ISEER Rating||Power Unit Consumption (for 1600 hrs usage)||Cost* (@6/Unit)||Yearly Saving (vs 3 Star)||% Saving (vs 3 Star)|
** The Below table shows the expected saving on buying split Acs with 3 or more energy star ratings. Values given are basis ISEER energy label on 1.5 Ton Voltas ACs (for 1600 hours of operation) & electricity charges of Rs.6 per unit. kindly note that non-inverter Split ACs do not come in 4 and 5 energy star ratings.
|Type||Energy Star Rating||Appox. annual energy consumption (units)||Annual electricity cost (in Rs.)||Annual Saving (in Rs.)|

Aluminium or Copper coil?
Aluminium or Copper
Air Conditioners provide a sigh of relief during the treacherous summer heat. But deciding the type of air conditioner which doesn’t hurt your pocket could be an uphill task. Apart from the other factors that determine which type of air conditioner is better, there is an age-old debate as to which type of coil is better – Copper or Aluminium?
There are various Pros & Cons of both. Following table showcases each:
|Cooling speed||Better heat transfer, cools faster||Slower cooling as compared to Copper|
|Corrosion resistant||Corrodes slowly||faster corrosion vs Copper|
|Durability||More durable & stronger||less durable than copper|
|Repair||Can be repaired easily||Difficult to repair and needs replacement|
|Cost||Expensive||Cheaper than Copper|
AC condensers use coils to cool the air, Copper Coils are popular as they cool faster, are easy to maintain and have a longer lifespan. While copper coils are generally more expensive, they have better heat exchange & anti-corrosive properties and are preferred in coastal areas. Aluminum Coils are relatively cheaper in comparison.

Inverter or Non-Inverter?
It’s a compressor that thinks and adjusts according to your needs. The compressor has variable speed and changes its frequency according to the surrounding temperature. If you, re looking for a long-lasting, more Energy-efficient AC, it is worth investing in.
Advantages of Inverter Acs:
Reduced Electricity Bills –
Inverter ACs consume lesser power as the compressor does not have to frequently reach maximum cooling speeds.
Consistent Cooling –
The compressor varies its speed for optimum cooling.
Long Lasting –
With lesser load on the compressor, you can expect a longer lifespan.
Benefits of ‘Inverter’ Split ACs over ‘Non Inverter’ Split AC
|Parameter||Inverter Split AC||Non-Inverter Split AC|
Cooling technology/ Compressor Type
|👍 Variable speed compressor which adjusts power depending on heat load||👎 Compressor is either on or off depending on heat load|
|👎 Priced INR ~2000 to 4000 more than non-inverter ACs||👍 Lower priced than inverter ACs|
|Cooling speed||👍 reaches set temperature faster||👎 takes more time to reach set temperature|
|Noise||👍 Quieter than non-inverter ACs||👎 Not as quiet as inverter AC because compressor switches off and on repeatedly|
|Compressor life||👍 Inverter compressors have longer life||👎 Compressor life is lesser compared to inverter Acs|
|Energy consumption||👍 Consumes lesser energy than non-inverter ACs||👎 Consumes more energy|
|Stabilizer||👍 Does not require stabilizer for a given voltage range. Potential Saving of INR ~1200-2200||👎 Needs stablizer usually|
Special Features of ACs
WiFi-enabled ACs or Smart ACs as they are popularly called are empowered to take voice commands and are designed to operate intuitively. With next-generation voice-controlled technology, these ACs are compatible with Amazon Alexa devices and can operate to operate on voice commands, backed by the internet of things (IoT) technology. The Wi-Fi connectivity gives you the comfort of operating your AC remotely control or pre-program your AC to set a temperature and cooling schedule as per your wish.
ACs with Adjustable Capacity
These ACs have a unique adjustable mode which can run on different capacities depending on the number of people and ambient weather conditions.
ACs that Cool at 52 Degrees Celsius
These ACs provide better cooling performance at higher temperature
ACs with Antibacterial Coating
The micro dust Anti-Bacterial Filters in these ACs keeps out both invisible dust and other pollutants and there by provide cleaner air.
Hot and Cold ACs
Hot & Cold Air Conditioners deliver comfortable air throughout summer, winter, and monsoon. They have the latest technological upgrades like Dual inverter compressor, active energy control, etc which ensures cool air in summer, warm air in winters, and dryer air in monsoons.
|Parameters||Regular Room Heater||Hot & Cold AC|
|Energy Efficiency (BEE star rating)||Energy efficiency is unknown||BEE star rating is available for informed decision making|
|Saving (vs having two appliances)||High power and cost consumption and can be used only during winters||Low on power consumption and helps save money. Can be used in all seasons.|
|Air Filters||No air Filters are present||Basic air filtration present for clean breathing air.|
|Thermostat||Available in some premium models. It cannot be used to get a desired temperature and has to be switched off manually.||Provides flexibility to select a comfortable temperature & turns off on reaching desired temperature|
|Ease of use||Heavy and bulky. It has to be manually operated and requires storage space during off season.||Operates with remote control Does not require any storage space during off season.|
