Air Duct Cleaning in Tseung Kwan O

Lint-clogged dryer vents are a leading cause of house fires and make dryers run long and hot. Annual cleaning of the vent run — not just the lint trap — restores airflow, cuts drying times, and removes the fire risk. It's cheap relative to the risk.

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.

In Tseung Kwan O, whole-system pricing depends on vent count and system count. Beware coupon offers far below market — the classic scam is a cheap teaser price followed by aggressive on-site upselling for 'mould remediation'. Get vent count and total price agreed in writing.

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.

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.

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.

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.
