Buying a large AC unit does not necessarily provide better cooling. The capacity of the unit should be chosen cautiously based on your room size. It involves three steps:

1. Measure square footage of the room

  • For square and rectangular rooms: Measure length and width in feet, and then multiply it.
How to measure areas
  • For triangle room shape: Calculate length and width of the room in feet, and multiply. Then divide it by two.
How to measure areas
  • For complex shaped rooms: Divide the room into square, rectangle or triangle shapes and apply above mentioned formula.
How to measure areas

2. Find the cooling capacity required for your room

An AC unit's cooling capacity is measured in British Thermal Unit (BTU) per hour. Following chart helps you find the right cooling capacity for your room size.

1 Ton = 12000 BTU/hr

Area to be cooled(in sqft) BTU per hour
450 to 550 12,000 = 1 Ton
550 to 700 14,000= 1.2 Ton
700 to 1,000 18,000 = 1.5 Ton
1,400 to 1,500 24,000 = 2 Ton
1,500 to 2,000 30,000
2,000 to 2,500 34,000

3. Exceptional cases

  • If the room has excessive sunlight, increase BTU capacity by 10%
  • If the room is heavily shaded, decrease the capacity by 10%
  • For kitchen, select an additional 4000BTU
  • If the room has more than two persons, add 600BTU per person

Check energy efficiency

Efficiency of an air conditioner is assessed by the Energy Efficiency Ratio (EER). Bureau of Energy Efficiency (BEE) provides ratings from 1 to 5 based on the efficiency and power consumption. High EER rating means the unit is more energy efficient.

Sleep mode: This feature provides a comfortable temperature during night. Sleep mode saves lots of energy.

Compressors: The air conditioners use specially designed compressors to deliver best cooling experience.

Auto defrosting: To protect the unit, auto-defrosting technology will stop functioning of fans and thus halts heating mode.
