Aircon Supply and Installation in Singapore
StringsSG supplies and installs aircons for HDB flats, condominiums and landed homes, from a single wall-mounted unit to a System 4 multi-split. Tell us the rooms you want to cool, or the brand and model you already have in mind, and we quote the unit and the installation together. If you are replacing an old aircon, mention it so the quote covers taking the old one down.

System 1, 2, 3 or 4: Which Do You Need?
In Singapore a "system" aircon means one outdoor condenser running several indoor fan coils. System 1 is one condenser with one fan coil; System 4 is one condenser with four. Most homes count one fan coil per room to be cooled, so a flat cooling the living room and three bedrooms needs a System 4, or a System 3 plus a separate System 1.
- Multi-split (System 2 to 4): one condenser on the ledge, less outdoor space used, usually cheaper than separate units. If the condenser fails, every room on it stops.
- Separate System 1 units: each room independent, so one fault does not take out the others, but you need ledge space for more condensers.
Choosing the Unit
- Cooling capacity. As a rough guide, a common bedroom takes a 9,000 BTU fan coil, a master bedroom 12,000 BTU and a living room 18,000 to 24,000 BTU, depending on size and how much sun it gets. The installer should size each room before quoting.
- Energy ticks. Aircons sold in Singapore carry the NEA energy label, rated in ticks; more ticks means lower running costs, which matters more than the purchase price over the unit's life.
- Inverter or not. Inverter units adjust compressor speed instead of switching on and off, which saves power in rooms cooled for long hours. See inverter vs non-inverter aircon.
- Brand. Daikin, Mitsubishi, Panasonic, LG and Samsung are all common here; parts availability and the servicing you can get matter more than the badge. Compare them in top aircon brands in Singapore.
What Affects Aircon Installation Cost
Installation is quoted per job because these change the price far more than the brand does:
- the system size and the number of fan coils
- the model and its tick rating
- how far the copper piping runs from each fan coil to the condenser, and how much trunking is needed
- taking down and removing an old unit
- electrical work, such as a new isolator or power point
- drilling through walls, and where the condenser goes: a ledge, or a bracket that needs work at height
HDB, Condo and Landed Homes
- HDB flats: the outdoor condenser goes on the flat's designated aircon ledge, and the work has to follow HDB's renovation guidelines for air-conditioner installation.
- Condominiums: check with your management (MCST) before booking; many condos set where condensers may go and the hours renovation work is allowed.
- Landed homes: more freedom on condenser placement, but keep units clear of neighbours' windows and leave space around them for airflow and servicing.
How Long Installation Takes, and How to Prepare
A single wall unit is typically installed within a few hours; a System 4 with new piping often takes most of a day. Clear the wall area, cover furniture near the fan coil positions, and expect some drilling dust. Before the technicians leave, test cooling, swing and every remote function in each room.
Once it is running, keep it running well: a new aircon still needs regular servicing. See how often to service your aircon and our annual servicing packages.
