How do brand & quality tier change the parts cost?
Brand and tier adjust the parts portion only — never labour. NIBE of Markaryd is the Swedish volume maker of ground-source, air-to-water and exhaust-air heat pumps, and its board prices set the 1.0 reference line every other brand is measured against. Panasonic and Samsung carry the lowest parts prices, followed by Thermia, Värmebaronen and Bosch. Fujitsu and Mitsubishi Electric sit highest, followed by CTC, Daikin and Vaillant, with Toshiba, Mitsubishi Heavy Industries, IVT and LG moderately above the line. On the ventilation side Systemair, Flexit and Östberg sit at the reference level and Swegon above it. ComfortZone and Energy Save have no published Swedish board price and are left at the reference level; EVI Heat, Viessmann and Swegon have none either and are set to the premium band median. The factors below are parts prices relative to the reference line — not a quality, reliability or market-share ranking — and they do not track the price tier: premium-tier Panasonic sits lowest because a split-AC board is a physically smaller item than a hydronic main board. Pick a tier in the calculator for a class-typical estimate, or a specific Swedish brand to override it.

Nordic Inverter 12 LRN-N/PR-N outdoor), median SEK 6,758.85 -- raw ratio 1.16 against SEK 5,807.00, reported conservatively at 1.15 because the basket is only three SKUs. A fourth search hit ('014B. Kretskort PAC-IF011B', SEK 12,491.00) was excluded: PAC-IF011B is a Mitsubishi Electric interface part number, not an IVT-built board.) |

| EVI Heat | ×1.3 | Parts ×1.3 (tier median (premium band). No publicly priced Swedish parts basket exists for EVI Heat. The premium brands in this guide that do carry observed parts evidence sit at 1.20, 1.30, 1.35, 1.35, 1.45 and 1.45, giving a band median of 1.35, reported one step lower at 1.30 because this brand carries no observed Swedish price at all. EVI Heat is a smaller Swedish maker of ground-source and air-to-water heat pumps, counted among the specialist brands alongside the four volume groups.) |
| Vaillant | ×1.35 | Parts ×1.35 (Two Vaillant boards with Swedish prices: SEK 5,028.00 (VA0020233814, kretskort el-inkoppling 3-fas, VWL ../5 400V air-source heat pump) and SEK 11,122.00 (VA0020150124, huvudkretskort 400V, VWF 5-19/4 flexoTHERM ground-source heat pump), median SEK 8,075.00 -- raw ratio 1.39 against SEK 5,807.00, reported conservatively at 1.35 because the basket is only two SKUs. Both items are heat-pump boards; the page lists no gas-boiler (gaspanna) board at all, so these two prices must never be used to price a Swedish gas-boiler repair.) |
| Viessmann | ×1.3 | Parts ×1.3 (tier median (premium band). No publicly priced Swedish board basket exists for Viessmann. The premium brands in this guide with observed parts evidence sit at 1.20, 1.30, 1.35, 1.35, 1.45 and 1.45 -- band median 1.35, reported one step lower at 1.30 because this brand carries no observed Swedish price at all. Viessmann is a German premium nameplate sold in Sweden mainly as heat pumps and cylinders, and is one of the brands counted outside the four Swedish volume groups.) |

| Swegon | ×1.3 | Parts ×1.3 (tier median (premium band). Swegon is stocked as a spare-parts brand by Swedish ventilation retailers, but no publicly priced Swegon control board is listed. The premium brands in this guide with observed parts evidence sit at 1.20, 1.30, 1.35, 1.35, 1.45 and 1.45 -- band median 1.35, reported one step lower at 1.30 because this brand carries no observed Swedish board price.

Is it worth repairing a thermostat & controls?
If the repair quote exceeds roughly half the price of a comparable new thermostat & controls — or the unit is well past its typical service life — replacement is often the better value. Localize the repair range above first, then compare.
Prices are county (län)-level estimates based on labour-cost data, not fake city precision. See the methodology for the localization method and named sources.
