Standard aircon servicing in Singapore costs between $45 and $80 per unit as of 2026, with the price varying by service type and unit count. Chemical overhaul typically runs $120–$250 per unit, gas top-up $80–$180 depending on refrigerant type (R32, R410A, R22), and chemical wash $90–$180. Many providers quote excluding extras; our quoted prices are final. Expect to pay $45 minimum for a single-unit service that includes a technician visit, 9-point pre-check, and standard cleaning—additional work like gas or parts is quoted transparently on-site.
Standard Aircon Servicing: What You Actually Pay
Standard servicing—sometimes called general servicing—covers the basics: cleaning filters, fan coil, drain tray, checking drainage, wiping down the blower wheel, inspecting refrigerant pressure, and testing operation. It does not include opening the unit for deep cleaning (that is chemical wash) or topping up gas.
| Number of Units | Typical Market Range (2026) | aircons.sg Price |
|---|---|---|
| 1 unit | $45–$80 | $45 |
| 2 units | $80–$140 | $70 |
| 3 units | $110–$200 | $95 |
| 4 units | $140–$260 | $115 |
| 5 units | $170–$320 | $125 ($25 per unit from 5 units) |
The $45 minimum at aircons.sg includes the technician visit, a 9-point pre-check (filter condition, drainage, gas pressure, electrical connections, coil cleanliness, blower wheel, condensate pan, thermostat calibration, and overall operational test), plus standard cleaning of accessible components. If the pre-check reveals issues—low gas, clogged drain pipe, faulty capacitor—the technician quotes the fix on the spot. If you proceed, the $45 is rolled into the total; if you decline, the $45 covers the visit and diagnosis.
Many competitors advertise $25 or $35 per unit but add GST (9%) at checkout and upsell aggressively once on-site. A '$25' service becomes $27.25 after GST, and you will hear 'your gas is low' or 'you need chemical wash' within five minutes. aircons.sg pricing is final—no surprises.
Chemical Wash vs. Chemical Overhaul: Price and When You Need Each
Chemical cleaning uses specialised solutions to dissolve mould, dirt, and scale that standard servicing cannot reach. Two levels exist: chemical wash and chemical overhaul.
Chemical Wash
The technician removes and dismantles the fan coil unit, soaks the blower wheel, evaporator coil, and drain tray in chemical solution, scrubs manually, then reassembles. Drainage pipes are flushed. This eliminates mould smell, improves cooling, and fixes minor drainage issues. Typical cost: $90–$180 per unit. aircons.sg prices chemical wash by unit count: $135 for 1 unit, $245 for 2 units, $345 for 3 units, $425 for 4 units, and $100 per unit from 5 units. Recommended every 12–18 months for typical household use, or sooner if you notice musty odour, weak airflow, or water leaking from the indoor unit.
Chemical Overhaul
The entire indoor unit is dismantled and removed from the wall bracket, every component (fan motor, coil, housing, PCB cover) cleaned separately, then reassembled and pressure-tested. This is the most thorough cleaning available. Cost range: $150–$250 per unit. aircons.sg prices chemical overhaul by unit count: $200 for 1 unit, $370 for 2 units, $515 for 3 units, $640 for 4 units, and $150 per unit from 5 units. Recommended every 2–3 years, or when standard chemical wash no longer resolves cooling or drainage problems. Also required if you have not serviced the unit in over two years and suspect internal corrosion or severe mould buildup.
When to Choose Which
- Standard servicing: Every 3 months (heavy use) or 4–6 months (moderate use); unit cools well, no leaks or smell.
- Chemical wash: Annually or when aircon smells musty, airflow is weaker than normal, or you see water pooling below the indoor unit.
- Chemical overhaul: Every 2–3 years, or if chemical wash did not solve the problem, or after prolonged neglect (unit not serviced for 2+ years).
Gas Top-Up Cost: R32, R410A, and R22 Pricing in 2026
Refrigerant gas does not 'run out' under normal operation—if your aircon needs a top-up, there is a leak. A responsible technician will identify and seal the leak before refilling; otherwise, you will need another top-up in weeks or months.
| Refrigerant Type | aircons.sg Price (incl. leak check) | Common in |
|---|---|---|
| R32 | $170 | Most inverter models from 2018 onward (Daikin, Mitsubishi, Midea) |
| R410A | $130 | Non-inverter and older inverter units (2010–2018) |
| R22 | $115 | Pre-2010 units; phased out under Montreal Protocol, increasingly scarce |
aircons.sg charges $170 for R32 top-up (most common), $130 for R410A, and $115 for R22 (subject to availability). Price includes leak detection with soap solution or electronic leak detector, nitrogen pressure test if required, vacuum pump evacuation, and refrigerant refill to manufacturer specification (typically 5–7 bar operating pressure for wall-mounted splits). If the leak is in a flare-nut connection, repair is usually included; if it is in the evaporator coil or condenser coil, replacement may be needed (quoted on-site, as the cost depends on part and brand).
Do not accept a gas top-up without leak detection. Some contractors skip this step to save time, and you will pay again in three months when the gas leaks out.
Additional Costs: Parts, Repairs, and High-Floor Surcharges
Common Replacement Parts
- Capacitor: $30–$60 (fan motor or compressor start capacitor; symptoms include compressor humming but not starting, or fan not spinning).
- PCB (control board): quoted on-site; the cost depends on brand and model, and generic boards for older non-inverter units are cheaper than inverter boards.
- Thermistor (temperature sensor): $40–$80; if faulty, aircon cycles on/off erratically or does not reach set temperature.
- Drain pump: $50–$100; needed if gravity drainage is not possible (e.g., indoor unit installed below the outdoor unit or drain pipe has no downward slope).
- Fan motor (indoor blower): $120–$250; if seized or burnt out, you hear grinding noise or no air comes out despite compressor running.
- Compressor: quoted on-site; catastrophic failure, usually not economical to replace on units older than 7–8 years—consider new installation instead.
High-Floor and Accessibility Surcharges
Outdoor condenser units installed above the 6th floor, on ledges without proper access, or requiring scaffolding, gondola, or rope-access work attract additional charges. Typical surcharges:
- 7th–12th floor (accessible ledge): +$20–$40 per unit
- 13th floor and above (narrow ledge, requires harness): +$50–$100 per unit
- Gondola or scaffolding required: +$150–$500 depending on building MCST-approved contractor requirements and rental duration.
HDB estates with external compressor platforms (common in newer BTO flats) usually do not incur surcharges up to the 20th floor, as the platform is accessed from the common corridor. Older HDB blocks and most condos place condensers on individual unit ledges, requiring technicians to climb out. Always inform your contractor of your floor level and accessibility before booking—reputable providers like aircons.sg will clarify surcharges upfront via WhatsApp, not surprise you on-site.
How Often Should You Service, and What Does Neglect Cost?
Singapore's 80%+ humidity and near-constant aircon use accelerate dust accumulation, mould growth, and condensate buildup. Manufacturer warranties typically mandate servicing every three months; skipping services can void warranty claims for compressor or PCB failure.
| Usage Pattern | Recommended Servicing Frequency | Annual Cost (1 unit, standard servicing only) |
|---|---|---|
| Heavy (10–16 hours/day, bedrooms, living room) | Every 3 months | $180 (4 services × $45) |
| Moderate (6–10 hours/day) | Every 4 months | $135 (3 services × $45) |
| Light (weekend use, guest room, study) | Every 6 months | $90 (2 services × $45) |
Skipping servicing for 6–12 months leads to clogged filters (20–30% higher electricity consumption), dirty coils (reduced cooling capacity, longer run times), and blocked drainage (water leaks, ceiling stains, potential electrical short). A neglected unit that could have been maintained for $180/year may require a $135 chemical wash and a $170 R32 gas top-up—$305 in reactive fixes, plus a capacitor replacement quoted on-site, plus the discomfort and potential damage to flooring or furniture from water leaks.
The 9-point pre-check included with every aircons.sg service booking catches these issues early: low gas pressure, marginal capacitor voltage, partial drainage blockage, coil fouling. Clearing a slow drain is a standard repair at $80; ignoring it until water floods your bedroom costs a $135 chemical wash, potential ceiling repair, and a very unhappy household.
Transparent Pricing vs. Hidden Fees: What to Watch For
Many advertised aircon servicing rates in Singapore are bait-and-switch. Here is what to verify before booking:
- Is the price final, or are charges added at checkout? If the ad says '$35 per unit' and checkout shows +9% GST, the real price is $38.15. Quoted prices are final; $45 means $45.
- Does the service include a genuine inspection, or just a filter wipe? Some $25 'services' involve a technician spending eight minutes wiping the filter and declaring 'you need chemical wash and gas'—no actual servicing done. A proper standard service takes 20–30 minutes per unit.
- Are parts and consumables included? Drain pipe flushing solution, coil cleaning spray, and filter cleaning should be part of standard servicing. Some contractors charge separately for 'chemical spray' (a few dollars of generic degreaser presented as a $15 upsell).
- Is the call-out fee waived if you proceed, or charged regardless? aircons.sg has no separate call-out fee; the $45 minimum covers visit + pre-check + servicing for one unit. Some competitors charge $30–$50 'diagnosis fee' even if you book the recommended work.
- What is the warranty on workmanship? aircons.sg offers 90 days on all labour. If a gas top-up leaks again within 90 days, we return and fix it at no charge (assuming no new damage). Many budget providers offer zero warranty; if the problem recurs in two weeks, you pay again.
Always confirm pricing via WhatsApp or phone before the technician arrives. A screenshot of the quoted price is your protection against on-site 'adjustments'.
Frequently Asked Questions
Is $45 for one aircon servicing considered cheap or expensive in Singapore?
$45 is mid-range and honest for 2026. Budget providers advertise $25–$35 but add GST and upsell aggressively; premium brands charge $60–$80. At $45 with a genuine 9-point pre-check included, you get transparent value without low-ball bait-and-switch tactics or inflated 'premium' branding.
How do I know if I need chemical wash or just standard servicing?
If your aircon cools normally, has no musty smell, and does not leak water, standard servicing every 3–6 months is sufficient. If you notice weak airflow, mould odour, or water dripping, book a chemical wash. The 9-point pre-check included with aircons.sg service bookings will flag these issues and recommend chemical wash only if genuinely needed.
Why does gas top-up cost vary so much between contractors?
Refrigerant type, whether leak detection is included, and whether the contractor uses a proper vacuum pump and pressure gauge all affect cost. Cheap gas top-ups often skip leak repair, vacuum evacuation, or use recycled refrigerant—resulting in another leak within weeks. At aircons.sg a gas top-up including leak detection is $170 for R32, $130 for R410A, and $115 for R22.
Do I need to service the outdoor condenser unit, or only the indoor fan coil?
Both. Standard servicing includes checking the outdoor condenser: cleaning the condenser coil fins (dust and pollen accumulation blocks heat rejection), checking refrigerant pressure, inspecting electrical connections, and ensuring the fan motor runs smoothly. Neglecting the outdoor unit causes high head pressure, compressor overwork, and reduced cooling efficiency.
Can I perform aircon servicing myself to save money?
You can clean or replace filters (most are washable, some are disposable) and wipe down the exterior every few weeks. However, checking refrigerant pressure, flushing drain pipes, cleaning the blower wheel, and inspecting electrical components require tools and experience. DIY chemical wash is not advisable—dismantling the fan coil incorrectly can damage the PCB or refrigerant lines, and the cost of fixing your mistake will exceed the $135 you tried to save.
What Can Change the Price on the Day
The prices above are the prices. What people actually want to know is when a number moves, so here is every case where ours does — all of it published on our aircon servicing price list, not decided at your door.
- Weekends do not cost more. Our quoted prices apply seven days a week within standard hours — 9am to 9pm Monday to Saturday, 10am to 6pm Sunday. A Saturday service is the same $45 for one unit as a Tuesday one.
- After-hours emergency calls do. Repair calls between 10pm and 7am carry a $50 surcharge. That is the only time-based surcharge we have.
- Restricted parking. In the CBD and Marina Bay area, where commercial parking is required, a $10–$20 surcharge applies. Standard transport everywhere else in Singapore is included.
- Major repair parts. A compressor or a PCB is quoted on-site, after the 9-point pre-check has confirmed that it is genuinely the part at fault. Everything else you see on the price list is final.
Notice what is not on that list: no "gas top-up needed" discovered five minutes after arrival, no per-floor charge, no callout fee stacked on top of the service. If you want the longer version of why other quotes move so much more than ours, we wrote it up in why aircon servicing prices vary so much in Singapore and in the hidden servicing fees to watch for.
Which Service Are You Actually Paying For?
Most overpaying happens at this decision, not at the price list. A general service at $45 will not fix a unit that has been left two years — you will pay $45, still have the smell, and then pay for the wash anyway. Equally, booking a $200 overhaul on a unit that is serviced every three months is money you did not need to spend.
The short version: general servicing is routine maintenance; chemical wash is the deep clean for mould, biofilm and weak airflow; chemical overhaul is the full strip-down for units that have been neglected or that a wash no longer rescues. We put the two chemical options side by side, with the price of each, in chemical wash vs chemical overhaul.
