Find a verified Ventilation Engineer in Ireland
MVHR systems, extractor fans, kitchen and bathroom ventilation by certified Irish installers.
What does a ventilation engineer do?
Ventilation specialists install and service ventilation systems in homes — extractor fans, MVHR (mechanical ventilation with heat recovery), positive input ventilation, and decentralised whole-house ventilation. As Irish homes have become more air-tight (driven by improved insulation and triple-glazed windows), proper ventilation has shifted from optional to essential. Without it, modern homes develop condensation, mould, poor indoor air quality, and excessive humidity.
Ireland ventilation work splits into three areas. Single-room extract (bathroom and kitchen extractor fans) is the basic level — required by building regs, mostly straightforward to fit. Whole-house MVHR systems run ducted air supply and extract throughout the home with heat recovery — the gold standard for new builds and deep retrofits. Positive input ventilation (PIV) is a simpler whole-house option that supplies fresh air through a single attic-mounted unit. The right system depends on the home's age, air-tightness, and budget.

How much does a ventilation engineer cost in Ireland?
Indicative pricing — your actual quote will vary
Ventilation pricing depends on system type and install complexity. The figures below are indicative Irish ranges.
A bathroom extractor fan (humidity-controlled, ducted to outside) is €150–€280 fitted. A kitchen cooker hood ducted to outside (when no ducting exists) is €350–€650 fitted. PIV (positive input ventilation) install is €700–€1,200 fitted including unit. MVHR full-house install retrofit (existing 3-bed semi, ducting through existing voids) is €4,500–€9,500. New-build MVHR (ducting designed in) is €3,500–€6,500. Annual MVHR service with filter change is €120–€220.
These are indicative ranges based on typical Irish jobs. Final pricing depends on scope, materials, urgency, and the trader you choose. On Jobiit you'll receive itemised quotes (labour, materials, VAT) so there are no surprises.

Ventilation Engineer FAQs
Do I really need ventilation if I open my windows?
Modern air-tight homes need mechanical ventilation. Window opening provides intermittent fresh air but doesn't address moisture in showers, cooking steam, or off-gassing of furnishings — all of which build up between window openings, especially in winter when windows stay closed. Building regs Part F requires specified ventilation rates in habitable rooms — basic extractors in wet rooms, plus background ventilation in living spaces (trickle vents, MVHR). Without it, condensation and mould risk increase significantly.
What's MVHR?
Mechanical Ventilation with Heat Recovery: a whole-house system that constantly extracts stale air from kitchen, bathrooms, and utility rooms, and supplies fresh air to bedrooms and living areas. The clever part is the heat exchanger — it recovers around 85% of the heat from outgoing air and transfers it to incoming air, so you get fresh air without losing your heating. MVHR is the gold standard for air-tight modern homes, especially those targeting heat pump heating.
PIV vs MVHR?
PIV (positive input ventilation) is a simpler approach: a single attic-mounted fan supplies filtered fresh air to the home, gently pressurising it and pushing stale air out through extractors and gaps. Cheaper to install (€700–€1,200) and effective at reducing condensation. MVHR is better for highly air-tight homes, recovers more heat, and has dedicated supply/extract per room. PIV suits older homes with moderate air-tightness; MVHR suits very air-tight new builds and deep retrofits.
Why does my bathroom keep getting mouldy?
Most likely the extractor fan is undersized, working only on a manual switch instead of a humidity sensor, or the ducting is restricted. Fix: install a humidity-sensing extractor fan with overrun timer that comes on automatically when humidity rises (during shower) and runs for 15 minutes after. Cost: €150–€280 fitted. If the fan is working but mould persists, the issue is the supply side — air coming into the bathroom may be cold, condensing on cool surfaces.
Do MVHR systems need much maintenance?
Annual filter changes and a service every 1–2 years. Filters cost €40–€80 per set; service with filter change is €120–€220. Skipping maintenance reduces effectiveness and can damage the unit. Most MVHRs are quiet workhorses if maintained — units installed in 2010-2015 are still running fine today. Choose a unit from a reputable brand (Vent-Axia, Brink, Zehnder) so spares and service are available long-term.
