Despite recent servicing, the unit cools weaker than before.
Musty smell
Sour or mouldy odour every time the aircon turns on.
Water dripping inside
Sludge is blocking the drain pan or condensate pipe.

Why Customers in the North Choose Us
Yishun Central Access Covers the Whole Estate
Our North-side team dispatches through Yishun Central and reaches Yishun North, West, and Khatib in a single service window. Access via Yishun Avenue 2 and 6 and Lentor Avenue keeps arrival times consistent. Most Yishun bookings complete in a single morning or afternoon across 2–3 HDB units.
Yishun HDB and Its Humidity Pattern
Yishun's northern humidity consistently produces the 'weak cooling plus mild musty smell' symptom profile — exactly the Non-Dismantle Chemical Wash sweet spot. Yishun Central and Yishun West blocks along Yishun Ring Road, Yishun Avenue 11, and around Khatib MRT show 10–15 year-old units that respond well to the lighter tier. Fewer Full-Dismantle cases than Bedok or Toa Payoh; more recurring 3-month maintenance.
Local Knowledge for Northern Singapore
Yishun occupies Singapore's northwest edge, with HDB estates fanning out from Yishun MRT and Northpoint City across Yishun Central, Yishun North, and Yishun West. The nearby Lower Seletar Reservoir and Mandai areas contribute to the northern humidity pattern that shapes aircon servicing across the estate.
The dominant aircon symptom here is 'weak cooling plus mild smell' — a Non-Dismantle sweet spot before the unit crosses into Full-Dismantle territory. This repeats across Khatib and the residential blocks south of Yishun Ring Road, particularly in 10–15-year-old HDB units.
Our north-side team reaches all Yishun zones via the SLE and Yishun Avenue 2. Typical turnaround is 2–3 units per household in a single morning window, with same-day availability confirmed via WhatsApp.
