Aircon Chemical Overhaul Singapore

from $130/unit · GST included · 90 days workmanship warranty

An aircon chemical overhaul is the deepest cleaning service available. The indoor fan coil unit is fully dismantled — fan blower, drain tray, casing, electrical components — and each part is cleaned individually with specialised chemicals. This catches issues that even a chemical wash cannot reach: PCB corrosion, fan blade grime, hidden mould inside the casing, and accumulated debris in cavities.

Frequently asked questions

Chemical wash vs chemical overhaul — which do I need?
Chemical wash cleans the coil without disassembly — good for routine deep cleaning every 6–12 months. Chemical overhaul fully dismantles the unit and cleans every component individually — recommended every 2–3 years, or sooner if your unit has serious fouling, persistent odour, or hasn't been overhauled in years.
How much does a full HDB aircon overhaul cost?
For a typical 3-bedroom HDB flat with 3 fan coil units, a full chemical overhaul costs $420 (incl. GST) at aircons.sg. 4-bedroom flats with 4 units cost $520. Pricing covers complete disassembly, individual component cleaning, and 90-day warranty.
Will chemical overhaul make my aircon work like new?
For units under 8 years old in good mechanical condition, yes — overhaul can restore most of the original cooling performance. Older units or those with worn compressors will improve significantly but may not fully recover original specs.
