Aircon installation in Singapore costs anywhere from about $700 for a simple one-room replacement to $5,000 and beyond for a full System 4 setup. That range is useless without context, so this guide breaks down real 2026 prices by system size, what is included, the add-ons that catch people out, and where it is safe to save money versus where cheap becomes expensive.
These are the actual prices we charge at Lion City Aircon, the same across HDB, condo and landed. We have installed and serviced aircons across 22,000+ jobs since 2016. All figures exclude 9% GST.
Installation Cost by System Size (2026)
- System 1 (1 bedroom or supplementing an existing setup): typically $1,000 to $2,000. Entry point: Mitsubishi Electric System 1, 9k BTU at $1,050. A Daikin 12k BTU runs around $1,187, and a 24k BTU single split for living rooms around $1,935 to $1,959.
- System 2 (master plus one bedroom): typically $2,000 to $3,000. Example: Mitsubishi Electric 9k+9k BTU at $2,405.
- System 3 (standard HDB or condo 3-bedroom): typically $3,000 to $4,000.
- System 4 (4 rooms, larger condos, landed): typically $4,000 to $5,000.
- Straight swap of one fan coil plus condenser: from around $700, since the piping and trunking are already in place.
- Add-ons: compressor brackets about $150 if needed. Longer pipe runs, concealed trunking and difficult access add labour, which is why we quote after a site survey rather than guessing.
Not sure which system size your home needs? Our guide to System 2 vs 3 vs 4 covers that decision, and HDB owners should read the HDB installation rules before committing.
So Is Installing an Aircon Expensive?
Compared to a fan, yes. Compared to what it does for daily life in Singapore, it is one of the better value renovations you can make. Two ways to look at it:
- Spread over lifespan: a $3,500 System 3 lasting 10 to 12 years works out under a dollar a day for whole-home cooling, before electricity.
- Where the real cost hides: running costs. An efficient 5-tick inverter system costs noticeably less per month than a cheap low-tick unit, and the gap over a decade often exceeds the upfront difference. Check the NEA tick rating before chasing the lowest sticker price. Our 2026 buying guide covers brand and BTU selection in detail.
What a Proper Installation Includes
A correct install is most of what determines how your aircon performs for the next decade. Ours includes the site survey, correct BTU matching to each room, quality piping and insulation (the corner cheap installs cut, and the one that causes leaking walls years later), proper vacuuming of the lines before charging, secure bracket mounting, drain routing with the right fall, and testing every unit before we leave.
Cheap installs go wrong in ways you only discover later: thin insulation that sweats inside the trunking, kinked pipes that choke flow, no vacuum pull so moisture stays in the lines, and drain runs without fall that drip within months. Fixing these costs more than the original saving.
Where You Can Save and Where You Should Not
- Safe savings: mid-range brands with good parts availability, buying during promotions, right-sizing the BTU instead of oversizing “just in case”, and skipping smart features you will not use.
- False savings: the lowest-quote installer, low-tick units, undersized systems that run flat out forever, and reusing degraded piping on a new system without checking it.
Considering whether to fix the old unit instead? See repair vs replacement for the honest decision framework.
Frequently Asked Questions
How long does installation take?
A straight one-unit swap takes 2 to 4 hours. A full System 3 or 4 with new piping and trunking is typically a full day, sometimes two for complex routing or landed properties.
Can I reuse my existing piping?
Sometimes. If the existing copper is the right size, in good condition and the insulation is healthy, reusing it saves real money. If it is degraded or the wrong gauge for the new refrigerant, reusing it is a false economy. We check before quoting.
Do I need to buy the aircon from you or can you install a set I bought?
Both work. We quote installation-only for units you have purchased, and supply-and-install packages like the Mitsubishi and Daikin examples above.
Why do quotes vary so much between companies?
Materials and labour shortcuts. Pipe and insulation grade, vacuum procedure, bracket quality and workmanship warranty are invisible in a quote line but decide how the system performs in year five. Ask what insulation class and pipe gauge are included and the cheap quotes get clearer.
When is the best time to install?
Before your old system dies or the hot season peaks. Demand spikes hard in the hottest months and lead times stretch. A planned replacement always beats an emergency one.
