Aircon Repair Singapore: Diagnostic-Led, Fixed Quotes, 90-Day Warranty

What Aircon Repair Covers

Aircon Repair is the right starting point when your unit is showing a fault but you are not sure whether it needs a chemical wash, a drainage clear, a refrigerant top-up, or a part replacement. Most Singapore aircon faults trace back to coil grime, drainage sludge, or low refrigerant rather than a genuinely broken compressor or PCB board. Every job starts with a diagnostic inspection so the fix matches the actual fault, not a guess.

The repair scope covers wall-mount split, cassette, and ducted units across HDB, condo, landed, and commercial properties. The most common repairs we run in any given week are drainage pipe unclogging for water-leak symptoms, chemical wash for ice or weak cooling, gas top-up only when pressure tests confirm the unit is low, and mould and bacteria treatment for foul-smell complaints.

When You Should Book a Repair Instead of a Service

Standard servicing keeps a clean, healthy aircon running. Repair is what you book when something is genuinely wrong: water dripping, ice on the coil, foul smell, mid-cycle shutdown, or no cooling at all. The line is usually clear once you spot a hard symptom rather than a gradual drop in performance.

Five hard indicators that point to repair territory:

1. Water actively dripping from the indoor unit. This is almost always a blocked condensate drain. A standard service will not clear it; the drain line needs to be flushed or the sludge in the drainage pan needs to be removed.
2. Ice forming on the evaporator coil. Restricted airflow from heavy coil build-up forces the refrigerant temperature too low. The fix is a chemical wash, not a top-up.
3. Foul or musty smell that persists after a regular service. Biofilm has colonised the coil deeper than a surface wipe-down can reach.
4. Aircon switching off mid-cycle. A safety switch is tripping. Either the drainage overflow switch or the refrigerant high-pressure switch has detected a fault that needs diagnosis.
5. Warm or weak air after a recent service. Either the coil is dirtier than the last service caught, or the refrigerant charge is low. The on-site diagnostic tells you which.

If you are not sure which tier of work you need, the fastest path is a WhatsApp message describing the symptom. We can usually narrow the likely cause from the description alone, then confirm the diagnosis on-site.

How a Diagnostic-Led Repair Differs From a Parts-Led One

A parts-led aircon repair starts by guessing what is broken and quoting a part replacement. Compressors and PCB boards are the easiest things to upsell because customers fear them most, but they are also the least common true cause. A diagnostic-led repair flips the order. We isolate power, open the cover, inspect the coil and drainage pan, run a pressure check, and only then put a fixed quote in writing.

The reason matters financially. A drainage unclog or chemical wash typically costs a fraction of a compressor swap. When the actual fault is something simpler, you save the difference. When the diagnostic confirms a genuine compressor or board fault, you still get the right repair, only now with photo evidence and a documented chain of reasoning rather than a guess.

We work on all major Singapore aircon brands, including Daikin, Mitsubishi Electric (Starmex), Panasonic (Enviro), Toshiba, LG, Midea, and Fujitsu. The diagnostic procedure is identical across brands. Repair-stage work varies by model bracket and drain pan design, which our technicians know from regular weekly servicing across the same units.

Local Coverage and Response Time

We cover Singapore island-wide for aircon repair, with same-day or next-day diagnostic slots in most weeks. Two dedicated emergency teams stay on standby for active leaks, mould outbreaks, and complete cooling failures. Our regular weekly run takes us through Bedok, Tampines, Jurong, Woodlands, Ang Mo Kio, Punggol, Sengkang, Toa Payoh, Bukit Batok, Yishun, Serangoon, and Geylang, so the response time depends mostly on how full that day already is rather than where you live.

Landed homes, CBD office buildings, and jobs starting after 6 PM carry a clearly-quoted add-on charge that we confirm on WhatsApp before booking. The repair scope itself is identical to HDB and condo work.

Pricing and What to Expect

Aircon Repair pricing is diagnostic-led. Common repairs are priced from published tiers: Non-Dismantle Chemical Wash from S$80 per unit, Full-Dismantle Chemical Overhaul from S$130 per unit, gas top-up from S$50 to S$200 depending on refrigerant type (R22, R410, R32), and drainage pipe unclogging quoted on-site after the inspection. Anything outside those common categories (compressor swap, PCB replacement, capacitor change) is quoted in writing after the diagnostic, with parts costed at the manufacturer rate plus our installation labour.

Payment is by PayNow, bank transfer, or cash on the day. A digital receipt is issued after payment, useful for warranty claims, tenant handover, and personal records.

For most Singapore households, an Aircon Repair visit either solves the symptom on the first appointment or hands you a clear written quote for the larger fix, with the diagnostic photos and pressure readings to back the recommendation up. WhatsApp the symptom and your address and we will book you in.
