Key takeaways
- Most air duct cleaning jobs in Singapore land between SGD 150–SGD 1,600 — known locally as aircon duct / ventilation cleaning.
- No licence covers residential duct cleaning in Singapore. Most homes use ductless split aircon (serviced separately); ducted systems appear in condos and landed properties, where BCA/SS 553 ventilation standards guide commercial-grade practice.
- Prices below are researched national ranges, updated July 2026 — not quotes.

What affects the price
- Job size and scope — bigger or more complex jobs move you up the ranges above.
- Access and condition — hard-to-reach areas, older properties or neglected maintenance add labour time.
- Materials and quality level — where materials are involved, the grade you choose often matters more than labour.
- Urgency — same-day or out-of-hours work usually carries a premium.
- Where you live — large metros in Singapore typically run above the national range; smaller towns below it.

- Be flexible on timing — off-peak slots are often cheaper.
- Bundle related tasks into one visit to spread call-out costs.
- Agree the scope in writing up front to avoid change-order surprises.

Frequently asked questions
Should ducts be sanitized or fogged with biocide after cleaning?
Usually no — blanket chemical fogging is discouraged unless there's confirmed microbial growth and the product is approved for HVAC use. Mechanical cleaning plus fixing the moisture source addresses the cause; fogging is the most-upsold, least-needed add-on.
How often should ducts be cleaned?
There's no fixed schedule — clean when there's visible mould, vermin, renovation dust, or significant debris buildup. In practice every 3-5 years is typical for forced-air homes, sooner after building work or if filters blacken quickly.
How long does whole-house duct cleaning take?
A typical single-system home takes 2-4 hours with a two-person crew. Larger homes, multiple air handlers, or heavy contamination stretch to a full day. Be suspicious of anyone promising a whole house in under an hour.
How is air duct cleaning priced?
Usually per system or per vent: a flat whole-house price for an average system, with surcharges for extra vents, multiple air handlers, or heavy contamination. Dryer vent cleaning is typically a smaller separate line item.
Does duct cleaning improve air quality or health?
Evidence is mixed for routine cleaning of already-clean ducts. It clearly helps when ducts contain mould, construction dust, pest debris, or blockages. Pairing cleaning with better filtration and sealing duct leaks delivers more measurable benefit than cleaning alone.
What is the duct cleaning scam I should watch for?
The pattern: a $50-100 'whole house special', then on-site claims of hidden mould with photos that may not be from your ducts, pressure-selling sanitizer fogging at hundreds extra. Legitimate firms quote by vent/system count, show you findings in your own ducts, and never pressure same-day decisions.
Does my Singapore flat need duct cleaning?
Only if you have ducted aircon (common in some condos and landed homes) or long kitchen-exhaust runs. Standard wall-mounted splits have no ducts — what they need is regular general and chemical servicing of the fan coil instead.
