Urgent Aircon Servicing Singapore

Same-day slots, technicians 8am to 10pm daily. Transport included, no callout fee.

Urgent aircon servicing in Singapore is for the faults that cannot wait until the weekend — water running down the wall, an outdoor unit tripping your breaker, or a bedroom unit that has stopped cooling on a 33°C night. Submit the request at any hour and we will assign a technician in your area, with same-day slots available during our service window.

Our booking platform takes urgent aircon requests 24 hours a day and technicians attend between 8am and 10pm, seven days a week, including public holidays. Pricing is the same as a scheduled booking — there is no emergency surcharge and no callout fee, and transport is already included in every price you see.

Which Aircon Service Do You Actually Need?

You do not need to diagnose the fault yourself. Start with what you are noticing, and we will point you to the right aircon service in Singapore — along with the likely cause, so you know why it is being recommended.

Nothing is wrong, the units are just due for upkeep
Filters, cover, evaporator coil and drain pan are cleaned, the drainage pipe is vacuumed and gas pressure is checked.
General Service
Weak airflow or a musty smell even after a normal service
Dirt has bonded to the evaporator coil. A surface clean will not shift it, so the coil needs chemical treatment.
Chemical Wash
Still cooling poorly after a recent service, or unit unused for months
The fan coil unit comes off the wall so the blower wheel, coil and full drainage line can be cleared.
Chemical Overhaul
Water dripping or leaking from the indoor unit
Almost always a choked drain line or dirty filters, not a refrigerant problem. Flushing the drainage usually fixes it.
Repair — drainage
Water pooling or a gurgling sound from the drain line
Sludge and algae build up inside the drainage pipe over time. Flushing it clears the blockage at source.
Drainage pipe service
Blowing air but it is not cold
The cause could be low refrigerant, a dirty coil, a failing capacitor or the PCB. We check before quoting any parts.
Book a diagnostic first
Rattling, buzzing or grinding noises
Usually the blower, indoor fan motor or a loose compressor mounting rather than the refrigerant circuit.
Repair — mechanical
Unit runs hot or shuts off after a while
Clogged filters and coils trap heat, so the unit cuts out on thermal protection after long run hours.
Overheating check
Outdoor unit runs hot, is noisy or trips the breaker
A condenser cannot reject heat when its fins are blocked, which makes the compressor overwork and trip.
Compressor Cleaning
Unit will not power on or ignores the remote
The PCB drives the fan coil and compressor. When it fails the system will not respond at all.
PCB Replacement
A technician has already confirmed the refrigerant is low
Refrigerant does not get consumed, so we locate the leak first. Refilling without fixing the leak wastes your money.

Still unsure? Book a general service. Our technician will tell you on site whether a chemical wash is actually needed — we do not add it by default.

How Fast Can We Get There?

Urgent requests submitted inside the 8am to 10pm window are assigned the same day wherever a technician is free nearby. Anything submitted overnight sits at the front of the queue and is assigned when the window opens the next morning.

The fastest route is WhatsApp — send a photo or a short video of the fault and the technician can bring the right parts on the first visit instead of returning a second time.

Before the technician arrives: switch the unit off at the wall, put a bucket and towels under any active leak, and clear furniture from underneath the fan coil unit.

Urgent Aircon Servicing FAQs

For urgent requests submitted during our service hours of 8am to 10pm, we aim to assign a technician on the same day, subject to availability in your area. Requests are accepted around the clock through the website and app, and anything submitted overnight is assigned first thing the next morning. The fastest route is to message us on WhatsApp at +65 9351 2695 and mark the job as urgent.

Our booking platform is online 24 hours a day, so you can submit an urgent aircon request at any hour and it will be in the queue immediately. Technicians are dispatched between 8am and 10pm daily, including weekends and public holidays. We do not send technicians out overnight, but an overnight request is picked up at the start of the next service window.

Urgent bookings are charged at our standard published rates - there is no emergency surcharge and no callout fee. General servicing starts at $47.84 for 1 unit and $57.41 for 2 units, a chemical wash starts at $82.80 per unit, a chemical overhaul at $149.04 per unit, and a full refrigerant gas top-up at $147.20 per unit. Transport is already included in every price shown, and your total is displayed before you confirm the booking.

The faults that genuinely cannot wait are water leaking onto flooring, walls or electrical fittings, an outdoor unit that trips your breaker or smells of burning, a unit that has stopped powering on entirely, and loud grinding or rattling from the blower or compressor. Poor cooling, weak airflow or a musty smell are uncomfortable but usually safe to book as a normal service slot.

Yes, in most parts of Singapore, provided you book within our 8am to 10pm service window and a technician is free nearby. Same-day availability is tightest in the late afternoon and during the hot season, so submitting the request early in the day gives you the best chance of a slot on the same day.

No. StringsSG does not add an urgency premium, a callout fee or a minimum booking fee. An urgent job is priced exactly the same as a scheduled one, with transport included, and no charges are added after the work is completed.

Switch the unit off at the wall to stop further water damage or electrical strain, place a bucket and towels under any active leak, and clear furniture from under the fan coil unit so the technician can work. Do not remove covers or attempt to open the unit yourself. If you can, send a photo or short video of the fault over WhatsApp - it helps the technician bring the right parts on the first visit.

Yes. We handle urgent servicing and repair for wall-mounted and ceiling cassette systems in HDB flats, BTO and resale units, condominiums, landed property and commercial premises across Singapore. For commercial sites, tell us your access and security requirements when you submit the request so the technician arrives prepared.

Most can. Choked drainage, dirty coils and filters, drain pan issues and refrigerant top-ups are normally resolved within the same visit. Faults that need a replacement part, such as a PCB, capacitor, fan motor or compressor, require the technician to diagnose first and then return with the part. You are told the cost before any parts work begins.

Yes, the same warranty as a scheduled booking: 30 days of workmanship warranty on general servicing and repair, 60 days on chemical wash, chemical overhaul and drainage work, and 90 days on refrigerant gas top-up. If the same fault comes back within that period, contact us through the app or on WhatsApp and we will send a technician back.

Describe the problem in the booking form at the top of this page and submit the request, or message us on WhatsApp at +65 9351 2695. You will see the price before confirming, and once the job is assigned you can chat directly with the technician in the app to confirm access details and timing.

Submit the request anyway - the platform accepts it at any hour and it enters the queue straight away for assignment when the service window opens at 8am. In the meantime, switch the unit off at the wall, and if there is water leaking or any smell of burning, leave it off until a technician has inspected it.
