Aircon repair across Jurong
Is your aircon dead on the hottest week of the month? You want someone who can come soon, and a price you know before they start.
That’s what our aircon repair is for. We handle units that won’t turn on, show an error blinking light, trip the power or stop cooling. Repair starts from S$60, and you get a fixed quote after diagnosis.
Urgent breakdown visits are offered on the same day in Jurong, subject to slot availability. Our team travels from Simei, so booking a day ahead gives you a wider choice of time slots.
Cool Earth Aircon, the team behind Aircon Servicing Jurong, has been fixing Singapore units since Brian started it in 2007 as a one-man workshop. Many of our Jurong West and Jurong East customers run two to four wall-mounted units, so we know how one breakdown can throw off the whole flat.
What we check on a repair visit
Every repair starts with a proper diagnosis. Using a multimeter test and the unit’s own fault codes, the technician checks:
- Power supply, fuses and wiring
- The PCB control board in the indoor and outdoor units
- The capacitor and magnetic contactor that start the compressor and fan
- Thermistor sensors that tell the unit the room and coil temperature
- The indoor fan motor and blower
- The compressor and, on inverter units, the inverter module
Once we know the cause, we explain it in plain words and give you a fixed price. You decide before any repair starts.
This order matters because the cheap parts fail first. A buyer’s guide from Mega Furniture notes that compressor capacitors fail often and cost very little to replace. A quick test can save you from paying for a bigger part you never needed.
Common faults by symptom
Unit will not turn on
Often a power supply issue, a blown fuse on the board, or a failed PCB. Sometimes it is just the remote or a tripped isolator.
Before you call, try these quick checks:
- Swap the remote batteries
- Check the aircon isolator switch near the unit
- Look at your DB box for a tripped breaker
If all three look fine, leave it off and book a visit. Repeatedly switching on a unit with a power fault can make the damage worse.
Blinking error light
Error codes point to a group of faults: sensor, fan, communication between indoor and outdoor unit, or the compressor. The codes differ between brands such as Daikin, Mitsubishi Electric and Panasonic, so we diagnose on site rather than guess from the code alone.
Online blink-pattern charts are a handy starting point. Even so, the same pattern can come from a loose wire or a dead PCB, and those two jobs sit at very different price points. Note down how many times the light blinks and share it when you book, as it helps us bring the right parts.
Not cooling
Dirty coils, low refrigerant or a failed part are the usual causes. See our aircon not cold repair page for more detail.
| Likely cause | What you may notice | Usual fix |
|---|---|---|
| Dirty coils | Weak airflow, ice on the indoor unit | Chemical wash, from S$80 per unit |
| Low refrigerant | Air feels mild, room cools slowly | Leak check and gas top-up, from S$80 |
| Failed part | Fan runs but outdoor unit stays silent | Part repair, from S$60 |
Leaking or noisy
Leaks are covered by our aircon water leak repair, and rattles, buzzing and grinding by noisy aircon repair.
Repair or replace?
Most faults are worth repairing. According to SJR Aircon, a Singapore servicing company, minor repairs typically run S$40 to S$300, while compressor or PCB replacement can climb to S$900. That top end is where the repair-or-replace question gets real.
| Situation | Our honest advice |
|---|---|
| Capacitor, sensor, fuse or fan fault | Repair |
| Single PCB fault on a newer unit | Usually repair |
| Very old unit, failed compressor or discontinued parts | Replacement often makes more sense |
If replacement is the better choice, we’ll say so plainly. Installation and replacement are handled by our parent company, Cool Earth Aircon, at coolearth.com.sg. We don’t push a new unit when a repair will do.
