Window AC vs Split AC

Split ACs  Window ACs

While split ACs are priced slightly higher than window ACs, the below table compares them on key parameters

Room Size

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

Energy Star Rating

Power Consumpation

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.

Power consumption (BEE) (ISEER)

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.

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:

CHARACTERISTICS COPPER ALUMINIUM
Cooling speedBetter heat transfer, cools fasterSlower cooling as compared to Copper
Corrosion resistantCorrodes slowlyfaster corrosion vs Copper
DurabilityMore durable & strongerless durable than copper
RepairCan be repaired easilyDifficult to repair and needs replacement
CostExpensiveCheaper than Copper
There are various Pros & Cons of both.

Copper Coils

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?

Inverter Technology

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

ParameterInverter Split ACNon-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

Price
👎 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
