While commercial spaces use central air conditioning or ceiling ACs, the slimmer split models are the most popular choice for households. While a window AC may be the cheapest option, it still requires sufficient space and wall thickness for support. To avoid calculations, the rule of thumb says a 1 ton AC covers up to 100 square feet, 1.5-ton covers around 180 square feet and a 2 ton AC can cool up to 240 square feet of space.įrom the cheaper but almost obsolete window unit to the latest energy-saving inverter models, there are many kinds of air conditioners to choose from. For offices and commercial spaces, the bigger 2 to 5 ton ACs are needed".
A representative from Singer says, "Considering average room size customers are most likely to purchase ACs between 1 to 1.5 tons for home use.
#TONS OF AC PER SQUARE FOOT WINDOWS#
Apart from room size, placement of windows and a number of sun-facing walls are also factors to consider. Alternatively, the volume of the room can be measured (in cubic feet) and divided by 1000, which shows how many tons an AC should be for efficient cooling.
But the easiest method is to multiply the length and breadth of a room (in feet), take the square root of the result and divide it by 10. Several online calculation tools measure the required tonnage (or cooling capacity) for an AC based on room size. The first thing to consider when buying an AC is the size of the room it will be placed in. For all latest news, follow The Daily Star's Google News channel.
