See the dedicated [aircon servicing price guide](/resources/aircon-servicing-price-guide) — general servicing, chemical wash, overhaul and contract prices compared.Aircon is priced by system type — how many indoor units run off one outdoor compressor. The more indoor units, the higher the cost. For 2026, a System 1 (one room) runs S$650–S$1,700, a System 3 (living room + two bedrooms — the typical 4-room setup) S$2,300–S$3,200, and a System 4 S$3,000–S$4,200. Premium brands and tricky installs push these higher.
The trap is what "installation" includes. Most quotes cover the units, brackets, basic electrical and 3–5 metres of piping — but longer copper runs, concealed trunking, a new power point or hoisting to a high floor all get added on. Always confirm what's in and what's extra before you commit.
| System | Typical cost (supply + install) | Suits |
|---|---|---|
| System 1 | S$650 – S$1,700 | One bedroom or study |
| System 2 | S$1,600 – S$2,200 | Small HDB / condo, 2 rooms |
| System 3 | S$2,300 – S$3,200 | Living room + 2 bedrooms |
| System 4 | S$3,000 – S$4,200 | Larger family layout |
| System 5 | S$3,800 – S$5,400 | Big condo, maisonette, landed |
Indicative 2026 ranges. Final price depends on brand, copper length, routing, access and site condition.
Which system do you need?
It's simply the number of indoor fan-coil units running off one outdoor condenser:
- System 1–2: one or two rooms — a bedroom, study or a small flat.
- System 3: the classic 4-room HDB setup — living room plus two bedrooms.
- System 4–5: larger flats, maisonettes, condos and landed homes with more rooms to cool.
Split systems are the norm here — energy-efficient and quiet. The unit itself is the biggest single cost: a 5-tick System 3 from Daikin or Mitsubishi Electric is around S$2,600–S$3,600 for the equipment alone, before install.
What's included — and what's extra
Standard installation usually covers the units, wall brackets, basic electrical connection and 3–5 metres of copper piping. Common add-ons:
- Extra piping: beyond the included length, about S$15–S$30 per metre depending on pipe size. A longer run from your bedroom to the service yard adds up.
- Stainless steel bracket: ~S$150 for older HDB flats with no aircon ledge.
- New dedicated power point: S$150–S$245 by a licensed electrician, if your flat lacks one (see the electrical guide).
- Concealed trunking / custom routing: quoted after a site check.
- Removing & disposing old units: extra in a resale changeout.
- High-floor surcharge: some installers charge for hoisting above the 12th floor.
Get the refrigerant right (R32, not R22)
This one saves you money long-term. Specify R32 for any new install — it's the current standard, 5–10% more energy-efficient and cheaper to top up if a leak develops. R22 is obsolete: if you're replacing an old R22 system, budget for a full changeout — you can't just swap the gas. Only stick with R410A if you're matching an existing multi-split.
The older-flat electrical catch
Your flat's electrical capacity can quietly add cost. Flats built after 1 January 1994 (or upgraded) usually have a 40-amp main switch — straightforward. Older flats often have a 30-amp switch, which means stricter limits on running current and possibly a permit for a new power point. If you're putting a System 4 or 5 into an older flat, check the capacity early — it can force an electrical upgrade you didn't budget for.
Sample budgets
System 3 in a new 4-room BTO (5-tick, mid-range brand): roughly S$2,300–S$3,200, mostly clean since BTOs have ledges and modern wiring.
System 3 resale changeout (remove 3 old units, ~5m extra piping, a new power point): closer to S$2,800–S$4,200 once removal, piping and electrical are added.
The costs people forget
- Piping beyond the included 3–5m — S$15–S$30/metre adds up on long runs.
- Old-unit removal & disposal — a resale changeout isn't just the new install.
- New power point / electrical upgrade — especially in older 30A flats.
- Brackets — ~S$150 if there's no ledge.
- High-floor hoisting — surcharge above the 12th floor.
- Cheap quotes = inferior materials — a rock-bottom price usually means standard-grade copper and brackets that cost you in leaks and repairs later.
Rules worth knowing
- Follow HDB's aircon installation guidelines — condenser placement, drainage and the like.
- Condos add MCST rules and tighter access, which lifts labour cost.
- Older flats may need a permit for a new power point; confirm your main-switch capacity (30A vs 40A) before a big system.
How to keep the bill sensible
- Right-size the system. Don't buy a System 5 if a System 3 cools the rooms you use.
- Specify R32 for efficiency and cheaper regas.
- Keep piping runs short where the layout allows — every extra metre costs.
- Bundle unit + install with one provider for warranty and accountability.
- Insist on an itemised quote — units, piping length, brackets, electrical — so you can compare fairly, and don't chase the rock-bottom price.

FAQ
How much does aircon installation cost in Singapore? By system: System 1 is S$650–S$1,700, System 2 S$1,600–S$2,200, System 3 S$2,300–S$3,200, System 4 S$3,000–S$4,200 and System 5 S$3,800–S$5,400 (supply and install). Most HDB homes use a System 3.
What does "System 3" mean? It's three indoor fan-coil units connected to one outdoor compressor. System 1 has one indoor unit, System 5 has five. The number reflects how many rooms you're cooling.
What's included in a standard installation? Usually the units, brackets, basic electrical connection and 3–5 metres of copper piping. Extra piping (S$15–S$30/m), trunking, a new power point, old-unit removal and high-floor hoisting are typically add-ons.
Should I get R32 or R410A? R32 for new installs — it's the current standard, more energy-efficient and cheaper to regas. R22 is obsolete and needs a full changeout. Only match R410A if you're extending an existing system.
Why is installation more expensive in older HDB flats? Older flats often have a 30-amp main switch (versus 40-amp in post-1994 flats), which can mean a permit for a new power point and limits on running current — sometimes forcing an electrical upgrade for larger systems.
Which aircon brand should I choose? Daikin, Mitsubishi Electric and Panasonic are the premium picks — higher efficiency and quieter, but pricier upfront. A 5-tick rating means better energy efficiency and lower running costs.
How long does installation take? A single split is 2–4 hours; a multi-split (System 3–4) takes 4–8 hours or about half a day to a full day. Ducted or VRV systems take 1–3 days.
