How To Calculate The Size Of Aircon

[ztycx 0]

anyone knows the formula to calculate aircon size locally? i found several formula online, but the results are deviated with each other.

the one from coolserve: area (square feet) * 65 BTU

the one from renotalk site: area (square meter) * 337 BTU

which one is more applicable in singapore?

It's the cubic volume of the room which matters. Not the area. Perhaps the formulas assume standard HDB ceiling height of 2.3 m or so. However, if you live in the top floor of HDB flat, the ceiling is 2.7m, and the formula may not work. If you live in a bungalow, the ceiling could be 3m, 4m even 5 m if you are really rich.

So you should really understand these better.
