Air-con... A rough guide
During our search, we found this site Singapore air-con.blogspot.com particularly useful. There is instructions on the site that teaches you how to read an air-conditioner catalogue, what to look out for in an air-conditioner, how to decide if the air-conditioner you are looking at have the features you want and tips on how to save energy when using the air-conditioner.
The other website we found quite good was this Choosing and Air Conditioner.
Air conditioners are rated in BTU (British Thermal Units). They are a measurement of how much heat is being transferred form the room to where the heat is dumped out doors.
How do I determine what size A/C I need?
Calculate the size of the room by multiplying the width of the room by the length of the room. To convert square metres to square feet, 1 sq m = 10.76 sq ft.
Using this area of your room size, you can determine the BTUs required to cool that particular room.
Below is a rough guide based on a room occupied by two adults, having average number of windows, and sun exposure.
I derived these figures based on the average from the quotation that was given to me during our search for an aircon.

| Room in SQ FT | BTU required |
| 100–150 | 5500–8250 BTU |
| 150–200 | 8250–11000 BTU |
| 200–250 | 11000–13750 BTU |
| 250-375 | 13750–20625 BTU |
