Daikin Aircon Servicing & Repair in Singapore

WeiWei Aircon has serviced Daikin air conditioners in Singapore for over 30 years. Daikin is the most installed aircon brand in Singapore homes — which means it’s also the brand our technicians work on most. From an iSmile unit in an HDB flat to full VRV systems in commercial buildings, we service every Daikin generation sold here.

Same-day slots available island-wide. Call or WhatsApp +65 6567 7698.

Our Daikin Aircon Servicing Solutions

Daikin General Servicing — Filters, blower, coils and drainage cleaned; refrigerant pressure and electricals checked. Quarterly aircon servicing is what keeps a Daikin inverter hitting the efficiency it’s famous for.

Daikin Chemical Wash & Overhaul — Weak cooling or musty smell that general servicing can’t fix means the evaporator coil needs a chemical wash. Heavily clogged units get the full overhaul — dismantled and cleaned part by part.

Daikin Gas Top-Up & Leak Detection — We pressure-test before topping up R32 or R410A refrigerant. Daikin units rarely lose gas without a leak — so we find the leak first instead of selling you a top-up every few months.

Daikin Aircon Repair — Error codes, water leaks, compressor and PCB faults — most Daikin repairs are diagnosed and completed in one visit.

Daikin Installation & Replacement — If a unit is beyond economical repair, we say so and quote a new installation honestly.

Daikin VRV Servicing for Commercial Buildings

Daikin invented the VRV system, and Singapore’s offices, shops and industrial units run on them. WeiWei services and maintains Daikin VRV systems end to end — regular maintenance schedules, fault diagnosis, compressor and PCB repairs — for offices, retail outlets, F&B and industrial premises. If your building’s VRV is under-cooling or tripping, our commercial team handles it with a maintenance contract or on call.

Daikin Models We Service

Every Daikin system sold in Singapore: iSmile and iSmileEco inverter series, MKS multi-split systems, wall-mounted FTK-series units, ceiling cassettes, and VRV commercial systems. Older discontinued Daikin models are routine work for our senior technicians — many Singapore homes still run Daikin units we first serviced over a decade ago.

Common Daikin Problems We Fix

Daikin error codes — Your remote can retrieve the fault code. Common ones we handle: A3 (drain water level — usually a clogged drain), A5 (freeze protection — airflow or refrigerant), E7 (fan motor fault) and U4 (indoor–outdoor communication). WhatsApp us the code when you book; the technician arrives knowing what to bring.

Daikin aircon not cold — Dirty coils, low gas or a compressor issue. We diagnose the real cause before quoting.

Water leaking from the indoor unit — The most common Daikin complaint, and almost always a blocked drain line. A chemical flush fixes it; regular servicing keeps it away.

Unit short-cycling or icing up — Often refrigerant pressure or a sensor fault. Switch it off and call — running it that way risks the compressor.

Noisy operation — Worn fan bearings or a loose blower. Cheap to fix early, expensive to ignore.

Looking for the Daikin Service Centre?

Straight answer: WeiWei is an independent Daikin specialist, not Daikin Airconditioning Singapore’s official service centre. If your unit is under manufacturer’s warranty, go official first — you shouldn’t risk the warranty. Out of warranty, an independent specialist is usually faster to schedule and easier on the wallet: 30+ years of Daikin experience, same-day slots, and a workmanship warranty on every job.
