Air Duct Cleaning in Tallaght

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.

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.

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 Tallaght, 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.

Filters need changing every 6-12 months, and duct runs plus valves benefit from cleaning every 3-5 years to hold airflow and heat-recovery efficiency. A neglected MVHR quietly degrades to noisy, ineffective ventilation.
