Size of the RoomRecommended AC Size
0 to 80 square feet0.75 Ton
80 to 120 square feet1 Ton
120 to 180 square feet1.5 Ton
180 to 300 square feet2 Ton
Size Vs AC ton requirement

TON:- It’s a number that tells how much heat the air conditioner can remove or soak from the house in an hour. TON is measured in BTU.

1 TON= 12000 BTU per hour means it can extract 12000 BTU of heat from room in one hour.

ISEER (Indian Seasonal Energy Efficiency Ratio)

ISEER (Indian Seasonal Energy Efficient Ratio) rating standard is mandatory from 2018.

Both  SEER and ISEER is same.

ISEER rating is the total cooling load (amount of heat removed) to the total amount of energy consumed by the air conditioner. This means, ISEER = Cooling seasonal total load (CSTL) / Cooling seasonal energy consumption (CSEC). The ratio calculated is then used to select the correct star ratings.


Currently required ISEER rating standard are as follow.

ISEER ratings for Window ACs (Fixed and Variable speed )
Star levelMinimumMaximum
1 Star2.502.69
2 Star2.703.89
3 Star2.903.09
4 Star3.103.29
5 Star3.30 3.50
ISEER ratings for Split ACs (Fixed and Variable speed )
Star levelMinimumMaximum
1 Star3.103.29
2 Star3.303.49
3 Star3.503.99
4 Star4.004.49
5 Star4.50 

Electricity Consumption of the AC

1 TON AC =  3.5KW

And with 5 star rating  = AC will be 3.5KW/3.5(5 star ISEER value)=1KW i.e 1000wattt.

So 1 ton ac with 5 star Ratting is having load of 1000 watt. Means running the  5 stat I TON AC for 1 hr will cost you 1 unit of electricity bill.


3 to  4 Star Air condition with ISSER rating of 3 to 4 is most affordable and efficient Air condition

Type/ category of AC

Type/ category of AC :-

Window AC : fits in window can be easily to use for rented house. And have high cooling but electricity usage is also high & high compressor noise.
