Typical fan coil sizes Singapore installers recommend for BTO room sizes.
| Room | Typical size | Recommended fan coil |
|---|---|---|
| Common bedroom / study | 9 – 11 m² | 9,000 BTU |
| Master bedroom | 12 – 15 m² | 9,000 – 12,000 BTU |
| Living room (3-Room) | 16 – 20 m² | 12,000 BTU |
| Living & dining (4-Room / 5-Room) | 22 – 30 m² | 12,000 – 18,000 BTU |
System 3 runs three fan coils off one outdoor compressor, usually the master bedroom plus two other rooms. System 4 adds a fourth fan coil, usually for the living room. Size up one step if the room faces west, is on a high floor with direct afternoon sun, or opens into the kitchen. These figures are a rule of thumb: ask your contractor to confirm sizes during the site survey.

What to check before installing aircon in your BTO flat.
For a standard 4-Room BTO flat, a System 4 inverter powering 3 bedrooms and the living room is most common. If the study room won't be air-conditioned, a System 3 is sufficient.
Standard 3/8-inch insulation can sweat in humid Singapore weather, causing water leaks through trunking boxes. 1/2-inch Class 0 Armaflex greatly reduces condensation and protects the copper piping.
Sponsor slots are only offered to BCA-registered mechanical and electrical contractors whose technicians are certified for R32 installation. Ask the contractor for their registration number before signing.
Reusing old copper piping is discouraged if the previous system used R22 refrigerant and you are switching to R32, as R32 runs at higher pressures and residual oil can clog the lines. A complete piping replacement is recommended for piping older than about 6 years.
