How do brand & quality tier change the parts 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 in the calculator for a class-typical estimate, or a specific Finnish brand to override it.

Is it worth repairing a air handler?
If the repair quote exceeds roughly half the price of a comparable new air handler — or the unit is well past its typical service life — replacement is often the better value. Localize the repair range above first, then compare.
