Signs You Need Commercial Wash
Cassette or ducted unit blowing warm or weak air
Commercial units run longer hours and accumulate coil build-up faster than residential. Overhead cassettes and concealed FCUs need specialist access for effective chemical cleaning.
F&B outlet with persistent kitchen or dining odours
Cooking grease aerosolises into aircon coil fins and accelerates biofilm growth. Standard residential chemicals won't cut heavy grease - specialist F&B formulations are required.
Office HVAC underperforming or affecting air quality
Ducted and ceiling-concealed systems in open-plan offices need access panel inspection and specialist chemical cleaning beyond standard residential scope.
Pre-lease or MCST reinstatement chemical wash
MCST and landlord reinstatement cleans require documented professional service. We provide NEA/BCA-compliant service with MCST-ready invoicing for handover records.
Commercial Aircon Chemical Wash in Singapore
Commercial aircon chemical wash differs fundamentally from residential. A wall-mount split unit sits at chest height with straightforward access; a ceiling cassette mounts overhead and needs drip collection plus ladder safety. Ducted and concealed systems require access panel inspection before any chemical work begins. F&B outlets carry grease build-up from cooking aerosolised across the dining and prep zones - standard residential alkaline detergent isn’t formulated for that load.
We service all three commercial unit types - cassette, ducted, and ceiling-concealed - across Singapore offices, F&B outlets, retail tenancies, CBD commercial buildings, and shophouse commercial spaces. Every job starts with an on-site inspection so we can quote accurately, then schedules around your operating hours. Our technicians hold BCA/NEA-compliant chemical handling certification for ACMV (Air Conditioning and Mechanical Ventilation) systems, which is the standard required for commercial and institutional properties in Singapore.

Cassette Aircon Chemical Wash
Ceiling cassette units common in Singapore offices and retail tenancies need a different chemical wash workflow than wall-mount splits. We dismantle the cassette face, set up overhead drip collection trays, and either soak the FCU components in a chemical bath beside the unit or remove them to ground level depending on access. Typical duration is 2–3 hours per cassette - longer than residential overhaul because of the overhead work and ceiling-tile reset.

Ducted and Ceiling-Concealed
Ducted aircon and ceiling-concealed FCUs require access panel inspection before chemical work starts. We open the access panel, inspect the ductwork with a borescope camera, then determine whether the concealed FCU needs to be extracted for bath soak or can be flushed in place. Half-day to full-day jobs depending on ceiling access.
F&B Outlets - Grease and Odour Specialists
F&B aircon units clog faster than any other commercial scope. Cooking grease aerosolises and settles on coil fins, accelerates biofilm growth, and produces persistent odour complaints from customers. Our F&B chemical wash uses a grease-cutting formulation and longer soak times to fully clear the build-up.
Recommended frequency for F&B kitchens is every 1–2 months; front-of-house dining areas every 2–3 months. We work after-hours - typically post-midnight or before opening - to avoid disrupting service.
Pricing - On-Site Quote
Commercial pricing is on-site quote because the variables (cassette height, ducted access, grease load, unit count) make fixed-tier pricing impossible to do honestly. We give you a written quote with line-item scope before any work starts. Volume discount applies at 5+ units per visit.
For pricing context across F&B, office, and retail scopes, see the Commercial Aircon Chemical Wash Pricing guide.
