Air Duct Cleaning in Himamaylan

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 Himamaylan, 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.

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.

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.

Only with ducted or ceiling-concealed aircon — found in some upscale condos and houses. Window and wall-split units need regular cleaning of filters and coils instead, which is the standard local aircon-cleaning service.
