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. Most providers quote excluding GST; aircons.sg does not charge GST, so 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 | $80 |
| 3 units | $110–$200 | $110 |
| 4 units | $140–$260 | $140 |
| 5 units | $170–$320 | $170 |
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 GST, 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 charges $120 per unit for chemical wash (no GST). 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 charges $180 per unit. 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 | Typical Cost per Unit (incl. leak check) | Common in |
|---|---|---|
| R32 | $80–$120 | Most inverter models from 2018 onward (Daikin, Mitsubishi, Midea) |
| R410A | $100–$150 | Non-inverter and older inverter units (2010–2018) |
| R22 | $120–$180 | Pre-2010 units; phased out under Montreal Protocol, increasingly scarce and expensive |
aircons.sg charges $100 for R32 top-up (most common), $120 for R410A, and $150 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 separately, typically $150–$400 depending 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): $80–$250 depending on brand and model; generic boards for older non-inverter units are cheaper; inverter boards for Daikin, Mitsubishi, or Panasonic are $150–$250.
- 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: $300–$800; 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 $120 chemical wash, $100 gas top-up, and $60 capacitor replacement—$280 in reactive fixes, 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. Fixing a slow drain costs $20–$40 for a flush; ignoring it until water floods your bedroom costs $120 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 GST included or added at checkout? If the ad says '$35 per unit' and checkout shows +9% GST, the real price is $38.15. aircons.sg does not charge GST; $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 no GST and 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 (R32 cheaper than R410A, R22 most expensive and scarce), 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. Expect $80–$150 for a proper job including leak fix.
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 $120 you tried to save.
