General aircon servicing cost
Routine maintenance — cleaning filters, blower, and cooling coil, flushing the drainage tray, and checking refrigerant pressure (see exactly what happens during a servicing, step by step). Priced per unit, with cheaper rates for recurring packages.
| Units | One Time | Twice Yearly | Thrice Yearly | Quarterly |
|---|---|---|---|---|
| 1 | $45 | $85 | $125 | $165 |
| 2 | $60 | $115 | $175 | $225 |
| 3 | $75 | $145 | $215 | $280 |
| 4 | $90 | $175 | $260 | $345 |
| 5 | $105 | $205 | $305 | $405 |
| 6 | $120 | $235 | $350 | $465 |
Twice / thrice / quarterly columns are the total annual price for that many visits. Six units on a quarterly plan works out to roughly $20 per unit per visit.
Chemical wash & chemical overhaul cost
Deeper cleans for units that smell, drip, or cool poorly despite regular servicing. A wash cleans in place; an overhaul dismantles the unit for the deepest clean. See the full aircon chemical wash (chemical cleaning) price breakdown for what the price includes and the step-by-step process.
Chemical wash
| Units | Price |
|---|---|
| 1 | $110 |
| 2 | $210 |
| 3 | $310 |
| 4 | $410 |
| 5 | $510 |
| 6 | $610 |
- • Additional units beyond 6: +$95 each
Chemical overhaul
| Units | Price |
|---|---|
| 1 | $150 |
| 2 | $280 |
| 3 or more | $130 / unit |
- • Wall-mounted 18,000 BTU units: $180 per unit
- • Wall-mounted 24,000 BTU units: $240 per unit
- • Ceiling cassette and ducted units cost extra
Gas top-up & condenser cleaning cost
Gas top-up prices restores cooling when refrigerant runs low; price depends on the refrigerant type and how much is needed. Condenser (outdoor unit) cleaning is priced by method.
Gas top-up (by refrigerant)
| Pressure | R22 | R410a | R32 |
|---|---|---|---|
| < 40 PSI | $90 | $120 | $130 |
| 41 - 80 PSI | $110 | $140 | $150 |
| > 81 PSI | $130 | $160 | $170 |
* Prices apply to single-split and multi-split aircon systems only. Larger systems (e.g. VRV/VRF) are quoted separately.
Condenser cleaning (by method)
| Method | Price |

How much does aircon repair cost in Singapore?
Repairs don’t have a fixed price list the way servicing does — the cost depends on which part failed and the brand of your unit. What is fixed is how the pricing works: troubleshooting is $50–$80 for home (multi-split) systems, and the fee is waived when you proceed with the repair or servicing. You get the exact quote after diagnosis, before any work starts — no obligation either way.
Simple fixes — a clogged drain cleared, a snapped flap replaced — sit at the low end. Part replacements (fan motors, sensors, circuit boards) depend on the part and the brand. A few real jobs from our recent Google Business updates:
Blowing warm air
The outdoor unit’s fan motor had burnt out — the fan wasn’t spinning, so the system couldn’t release heat.
✓ Fan motor replaced
Turning on and off by itself
A faulty motherboard and receiver sensor — the unit was responding to signals it should have ignored.
✓ Motherboard and sensor replaced
Suddenly stopped cooling
The compressor fan blade had grown brittle with age and snapped.
✓ Fan blade replaced
Water dripping from the indoor unit
A heavy build-up was blocking the drainage path, forcing condensation back out through the unit.
✓ Drainage cleared and flushed
Every aircon in the house dead
A burnt electrical connection in the power supply to the units — the aircon themselves were fine.
✓ Electrical fault isolated and repaired
Noisy outdoor compressor
Faulty bearings inside the compressor’s motor were causing the racket.
✓ Motor ordered and replaced

What affects the cost of aircon servicing?
Number of units
Price is charged per indoor unit, but the per-unit rate drops as you add units — a 6-unit service costs far less per unit than a single unit.
One-time vs recurring package
A recurring quarterly or tri-annual contract lowers the per-visit price significantly versus booking each visit one-off.
Service depth
Routine servicing is the cheapest. A chemical wash (deeper clean) and chemical overhaul (full disassembly) cost more because they reach dirt that filter-level cleaning cannot.
Unit type & BTU
Larger units (18,000–24,000 BTU), ceiling cassettes, and ducted systems take longer and cost more than standard wall-mounted units.
Condition & history
A unit neglected for years may need an overhaul rather than a wash, and a gas top-up if refrigerant has leaked — both add to the bill.
Why regular servicing costs less than a repair
Servicing feels like a cost you could skip — but skipping it is almost always the more expensive path. Here’s what regular maintenance actually saves you.
Repairs cost far more than upkeep
A routine service is a small, predictable cost. Letting dirt and low gas go unchecked leads to breakdowns — a failed compressor, motor, or control board can cost many times a year of servicing, plus the wait and the discomfort of no cooling until it’s fixed.
A dirty aircon burns more electricity
A clogged filter alone can raise an aircon’s power use by 5–15%, and a dirty outdoor condenser by up to 30% (US Dept of Energy). Regular cleaning keeps the coil efficient, so the compressor works less and your bill stays lower.
Neglect shortens the unit’s life
Running a dirty, overworked unit wears the compressor out faster. Regular servicing helps an aircon last its full 10+ years instead of needing an early — and far pricier — replacement.
How often should you service?
The harder a unit works, the faster it fouls — so how often you should service depends on how much you run it, and what’s in the air around it.
| How you use it | Example | Service every |
|---|---|---|
| Light use | A bedroom unit run a few hours at night | Every 4–6 months |
| Typical home use | Daily use in a living room or bedroom | Every 3–4 months |
| Heavy use | On most of the day, or near a kitchen or open windows | Every 2–3 months |
Cooking oil vapour, aerosol sprays, and haze from open windows all get drawn in and speed up how fast the coil clogs — so units near a kitchen or run around the clock need cleaning more often.
For the full breakdown — including the signs you’re overdue and what skipping servicing really costs — see how often to service your aircon in Singapore.
Worked example: a typical HDB flat
Here’s what regular servicing actually costs for a common setup — a 3-room HDB flat with three wall-mounted units.
One-time, when you remember
$75
for all three units ($25/unit), each time you book
Convenient, but it’s easy to forget — and gaps let dirt build up until a $110+ chemical wash is needed.
Best value
Quarterly package
$280/year
four visits — about $23 per unit each visit
All three units cleaned four times a year for $280 — less than four separate one-time visits would cost ($300) — and the regular cleaning heads off the dirt build-up that leads to costly washes and repairs.

Inverter vs non-inverter: which costs less to run?
The type of unit you own shapes your long-run cost as much as how often you service it. Servicing costs about the same for both — the real difference is the electricity bill.
Non-inverter (fixed-speed)
The compressor runs at full power until the room hits temperature, then switches off — cycling fully on and off all day.
- • Cheaper to buy
- • Uses more electricity, especially over long hours
- • Best for light or occasional use
Inverter
The compressor varies its speed to hold the temperature steadily, avoiding the power-hungry stop-start cycle.
- • Higher upfront cost
- • Uses less electricity — the savings grow the more you run it
- • Pays back best with heavy daily use
Whichever you own, a dirty coil erodes the efficiency — so regular servicing is what keeps an inverter’s lower running cost actually low.
How to choose an honest aircon company
The cheapest quote isn’t always the cheapest in the end. Some companies win the job on price, then upsell or cut corners — complaints Singapore homeowners share online all the time. Here’s what to watch for.
Upselling you don’t need
Pushing a gas top-up or a chemical wash on a unit that’s barely a year old, when a normal service would do. A good technician recommends the lightest service that fixes the problem — not the most expensive one.
Surprise add-on charges
Extra fees sprung on the day to clean the blower or roller, or clear the drain — things that should be part of a standard service, not billed separately once they’ve started.
Rushed, surface-level work
A quick wipe-down passed off as a full service, so the unit is dirty and cooling weakly again within weeks. Proper servicing cleans the coil, blower, and drainage — not just the visible panel.
Vague, moving quotes
No clear price upfront, then a bill that grows once the technician is on-site. Transparent companies publish their rates and stick to them.

How to keep your servicing cost down
- Service regularly (every 3–4 months) so dirt never builds up enough to need an expensive chemical wash or overhaul.
- Take a recurring package (bi-annual, tri-annual, or quarterly) instead of paying one-off rates — the per-visit price drops sharply.
- Bundle every unit into one visit — the per-unit price falls the more units you do at once.
- Vacuum and rinse the washable filters yourself every few weeks — it keeps airflow up between services and delays the next deep clean.
- Run the aircon only when you need it, and close doors and windows so it isn’t fighting the outdoor heat — less runtime means slower fouling and lower bills.
- Keep cooking grease and aerosol sprays away from the unit — oily vapour gets drawn in and bonds with dust into grime that forces an earlier chemical wash.
- Set a sensible 24–25°C rather than the lowest setting — the compressor works less and the coil stays cleaner for longer.
- Fix small issues early — a routine service is far cheaper than a compressor or motor replacement later.
What we never charge
- ✓ No hidden fees — the price we quote is the price you pay
- ✓ No call-out or out-of-area surcharge — same price island-wide
- ✓ No upselling — we recommend the lightest service that fixes the problem
