Aircon servicing in Singapore runs **S$30–S$60 per unit** for general servicing, **S$80–S$150 for a chemical wash**, and **S$150–S$250 for a full chemical overhaul**. Most homes need general servicing every 3 months and a deeper clean once a year — and knowing which service you actually need is how you avoid paying overhaul prices for a filter clean.Quick answer: Book general servicing at S$30–S$60/unit quarterly (cheaper on multi-unit or contract packages). If cooling stays weak after general servicing, step up to a chemical wash (S$80–S$150). Reserve the full overhaul (S$150–S$250) for units with leaks, odours or years of neglect.
Key takeaways
- General servicing: S$30–S$60/unit — filters, coils, mode checks; the quarterly routine.
- Chemical wash: S$80–S$150/unit — coil-deep chemical clean when cooling weakens.
- Chemical overhaul: S$150–S$250/unit — full dismantle, the reset button for neglected units.
- Contract packages (3–4 visits/year) cut per-visit rates 20–30% — worth it from 2+ units.
Servicing rates at a glance
| Service | Price per unit | When you need it |
|---|---|---|
| General servicing | S$30 – S$60 | Every 3 months — filters, coil vacuum, drain flush, gas-pressure check |
| Chemical wash | S$80 – S$150 | Weak cooling that servicing doesn't fix; yearly for heavy use |
| Chemical overhaul | S$150 – S$250 | Leaks, odours, frozen coils, or years without deep cleaning |
| Gas top-up (R32/R410A) | S$60 – S$150 | Cooling weak + low pressure confirmed — after a leak check |
| Troubleshooting / diagnosis | S$50 – S$80 | Faults — often waived if you proceed with repair |
| Servicing contract (per unit/year) | S$100 – S$200 | 3–4 scheduled visits; priority booking |
Indicative 2026 ranges for residential split units. Multi-unit bookings are cheaper per unit; ceiling cassettes and ducted systems cost more.
What each service actually includes
General servicing (S$30–S$60) is the maintenance visit: clean the filters and front panel, vacuum the indoor coil, flush the drain pipe, check gas pressure and modes. Twenty minutes per unit done properly. This is what keeps your aircon efficient and your electricity bill sane — most cooling complaints trace back to skipped servicing.
Chemical wash (S$80–S$150) goes coil-deep: the technician applies a chemical solution to dissolve the grime a vacuum can't lift, then rinses. The proper version dismounts the fan coil; a "chemical wash" done entirely in-place is often just a heavy rinse — ask before booking. Full comparison: chemical wash vs overhaul.
Chemical overhaul (S$150–S$250) is the reset button: full dismantle of the fan coil unit — blower wheel, drain tray, coil — everything chemically cleaned, bearings lubricated, then reassembled. For units with persistent odours, leaks or years of neglect, this restores near-new performance and typically comes with a workmanship warranty (30–90 days — ask).
How often should you service?
| Usage | General servicing | Deep clean |
|---|---|---|
| Daily (bedrooms, WFH) | Every 3 months | Chemical wash yearly |
| Moderate (weekends, living room) | Every 4–6 months | Chemical wash every 12–18 months |
| Heavy (24/7, pets, near roads) | Every 2–3 months | Consider yearly overhaul |
Singapore's humidity and dust mean aircons here clog faster than the manual assumes. The cheapest maintenance strategy is boring regularity: quarterly general servicing catches the small stuff while it's still a S$40 visit instead of a S$200 wash — or a S$900 compressor failure.
What moves the price
- Number of units — most companies price per unit with multi-unit discounts; servicing a System 3 in one visit beats three separate bookings.
- Unit type — wall-mounted splits are the base rate; ceiling cassettes add S$20–S$40; ducted systems are quoted separately.
- Condition — a unit that hasn't been touched in two years may need a wash before a contract makes sense; expect the technician to say so.
- Contract vs ad-hoc — annual contracts (3–4 visits) run S$100–S$200 per unit per year, roughly 20–30% below ad-hoc rates, with priority scheduling in the hot months.
- After-hours and urgent slots — same-day or evening bookings carry a S$30–S$80 premium.
Signs you need more than general servicing
- Cooling stays weak after a servicing visit → chemical wash, or a gas-pressure problem.
- Water dripping from the indoor unit → clogged drain — see aircon leaking water fixes.
- Musty smell when it starts → mould in the coil or blower — wash or overhaul territory.
- Ice on the pipes or coil → airflow or gas issue — stop using it and get a diagnosis.
- Unit is 8+ years old and struggling → weigh repair spend against replacement cost.
How to choose a servicing company
- Per-unit pricing in writing — including what a "chemical wash" includes (dismounted or in-place).
- Brand experience — Mitsubishi, Daikin, Panasonic and Midea each have quirks; experienced techs know them.
- Workmanship warranty — good companies back washes and overhauls for 30–90 days.
- Contract terms — visits scheduled in advance, not "call us when you remember".
- Reviews that mention punctuality and cleanup — servicing happens in your bedroom; professionalism matters.

FAQ
How much does aircon servicing cost in Singapore? General servicing runs S$30–S$60 per unit, chemical washes S$80–S$150, and full chemical overhauls S$150–S$250. Annual contracts with 3–4 visits work out 20–30% cheaper per visit.
How often should I service my aircon in Singapore? Every 3 months for daily-use units, with a chemical wash roughly once a year. Singapore's humidity and dust clog units faster than manufacturer schedules assume.
What's the difference between general servicing and chemical wash? General servicing cleans filters and vacuums coils — maintenance. A chemical wash dissolves embedded grime with chemical solution, ideally with the fan coil dismounted — restoration. If cooling stays weak after servicing, you need the wash.
Is an aircon servicing contract worth it? From 2+ units, usually yes — S$100–S$200 per unit per year covers 3–4 scheduled visits at 20–30% below ad-hoc rates, and you stop forgetting to book.
Why is my aircon still not cold after servicing? Likely low gas (needs a leak check before topping up), a coil that needs a chemical wash, or a component fault — see our full troubleshooting guide for the fixes and costs.
Can I service my aircon myself? Filters and exterior wipe-downs, yes — monthly DIY helps. Coils, gas and electricals need a technician; see our DIY aircon cleaning guide for where the line sits.
