Categorization By Capacity

Air conditioners can be categorised as per their cooling capacity. The common unit used to categorise is the ton. A ton of cooling power means the unit can cool equal to the cooling power of 907 kilograms (2000 pounds) of ice melting in a 24-hour period. A more specific way to measure cooling capacity is with the unit of BTU (British Thermal Unit). A ton of cooling power is about 12,000 BTU or 3,517 watts.

Star rating for air conditioners

Bureau of Energy Efficiency evaluates and categorises electrical home appliances in terms of their electric consumption and rates with 1 to 5 stars. A 1 star rated appliance consumes more power whereas a 5 star rated appliance is highly efficient with least power consumption. An AC with more number of stars means it is highly energy-efficient.
