How do brand and quality tier change the repair cost?
Brand and tier adjust the parts portion only — never labour. Parts prices vary by brand, and they say nothing about how good a unit is. The reference level here is Mitsubishi Electric, whose control boards average €805.18. Pricier boards were observed for CTC, LG and Mitsubishi Heavy Industries, cheaper ones for Panasonic, Viessmann, Fujitsu, Thermia, Bosch and Toshiba. For many brands — among them Daikin, NIBE, Samsung and Vaillant, and the Finnish makers Jäspi, Gebwell, Lämpöässä, Oilon, Vallox, Enervent and Ariterm — no publicly priced control board is available, so no price difference is claimed either way. The price observations come from a Nordic euro parts storefront, not from a Finnish shop's price list. Pick a tier for a class-typical estimate, or a specific Finnish brand to override it.

Ductwork & Vents adding a vent or duct run to a room: what usually causes it? Estimated
-
Fitting a new make-up air valve in an external wall
Pro recommended€155–€400
The most common addition to a Finnish house is a make-up air valve in a bedroom, when airtight windows have ended the natural supply of make-up air or a fireplace has been installed. The valve costs EUR 39–99.40 and the rest is labour: a hole is drilled through the external wall, the valve is fitted and the penetration sealed. As a separate visit the floor of the invoice is set by the minimum charge, which in the price list is two hours, that is EUR 153.12. The top of the range means a thick or masonry wall and an acoustically attenuated valve. The work has to be done deliberately in accordance with the ventilation design, because a wrongly sited valve causes draughts.

Running a new extract duct and roof penetration for a roof extract fan
Pro recommended€700–€2,200
In Finland a new extract duct is typically run to a basement, a garage or a renovated bathroom, and it ends at the roof in an extract fan or a rain cowl. A roof extract fan costs EUR 222.99 in retail and the roof penetration parts tens of euros; the rest is work in the loft and on the roof. The top of the range means a long duct, opening up the roof and a penetration through a metal roof. The extract fan's electrical supply is fixed electrical installation work, so it is done by a contractor holding electrical competence.

How much is a service-call fee for ductwork & vents repair?
Most Finnish companies charge a call-out / diagnostic fee of €30–€155, often credited toward the repair if you go ahead. It is separate from the repair totals above. VAT (ALV, 25.5%) may or may not be included: many small heating and ventilation firms and sole traders fall under Finland's small-business VAT exemption threshold (turnover up to €20,000 a year, the limit in force since 1 January 2025) and charge no VAT — so treat 25.5% as a ceiling, not a guaranteed add-on. No reduced rate covers heating-equipment repair. Finland's household tax credit (kotitalousvähennys) does not reduce the invoice; it is claimed later in your own tax return.
Is it worth repairing a ductwork & vents, or should you replace it?
A common rule of thumb: if the repair cost exceeds roughly half the price of a comparable new unit — or the appliance is past ~8 years for a ductwork & vents — replacement is often the better value. The calculator's localized totals give you the number to weigh against a new-unit quote.
