Frequently asked questions
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.
What does professional duct cleaning actually involve?
Proper source-removal cleaning puts the system under negative pressure with a high-power vacuum, then agitates each duct run with rotating brushes or compressed-air whips so debris is pulled to the collector — not blown into the house. Register covers, the air handler, and coils should be included.
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.
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.
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.
Which Hong Kong homes actually need duct cleaning?
Mainly larger flats and village houses with ducted (concealed) aircon, plus long kitchen-exhaust runs. If you have wall or window units, skip duct cleaning — book fan-coil cleaning instead.
