How do brand and quality tier change the repair cost?
Brand and tier adjust the parts portion only — never labour. The factors below are parts prices relative to the Danish mainstream baseline — not a quality or reliability ranking. We only say higher or lower about brands we actually found Danish shop prices for. Panasonic is the reference line (1.0) and Bosch sits right on it (1.05). Vaillant, Baxi and Nilan sit lower (0.80), because a gas-boiler board and a ventilation control board are cheaper components than a heat-pump board — that is a statement about the part, not about the brand. LG sits higher (1.40), and highest are the Japanese air-to-air brands Mitsubishi Electric, Mitsubishi Heavy Industries, Daikin and Fujitsu (1.50). For Buderus, Milton, Vølund, Metro Therm, Genvex, Danfoss, Viessmann, Weishaupt and NIBE we found no public Danish parts price, so they sit at the 1.0 reference level. That means we found no price evidence — not that their parts cost the same as Panasonic's. We describe those by role rather than by price level: Buderus, Milton, Viessmann and Weishaupt are gas-boiler nameplates carried by Danish plumbing retailers; Vølund and Metro Therm are Danish makers of boilers and air-to-water heat pumps; Genvex makes heat-recovery home ventilation; NIBE is an established heat-pump brand; and Danfoss covers controls and thermostats. Toshiba's 1.50 is likewise not a measured price but the mid-level of the Japanese brands in the table. Pick a tier for a class-typical estimate, or a specific Danish brand to override it.

The four Japanese brands in this file that DO carry Danish parts evidence -- Mitsubishi Electric, Mitsubishi Heavy Industries, Daikin and Fujitsu -- all sit at the 1.50 policy cap, so 1.50 IS that band's median. Because that median is itself a capped value, Toshiba's 1.50 inherits the cap rather than resting on an observed Danish ratio. Toshiba is named among the most-sold heat-pump brands in Denmark alongside Panasonic, Mitsubishi, Daikin, Bosch and LG.) |

How much is a service-call fee for air handler repair?
Most Danish companies charge a call-out / diagnostic fee of 850–1.600 kr., often credited toward the repair if you go ahead. It is separate from the repair totals above. VAT (moms, 25%) may or may not be shown separately: it is Denmark's single flat rate — there is no reduced rate for heating, cooling or ventilation work — but very small traders below the DKK 50,000 annual VAT-registration threshold charge no VAT, so treat 25% as a ceiling, not a guaranteed add-on.
Is it worth repairing a air handler, 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 air handler — replacement is often the better value. The calculator's localized totals give you the number to weigh against a new-unit quote.
