How do brand & quality tier change the parts cost?
Brand and tier adjust the parts portion only — never labour. Value brands such as Junkers/Bosch and Brötje carry the cheapest, most widely stocked parts; Elco, Buderus and Vaillant form the core of the Swiss heating market, while premium makers like Hoval, Viessmann and Weishaupt use higher-grade, often OEM-restricted components — with CTA, Alpha Innotec, Stiebel Eltron, Daikin and Mitsubishi Electric common on the heat-pump and mini-split side. Pick a tier in the calculator for a class-typical estimate, or a specific Swiss brand to override it.
| Brand | Parts factor | Basis |
|---|---|---|
| Mid-range tier parts ×0.975 | ||
| Vaillant | ×1 | Baseline — no parts adjustment |
| Buderus | ×0.85 | Parts ×0.85 (Buderus is one of the largest heating brands in Switzerland. At the same retailer that supplies the reference price, original Buderus spare parts sit in the lower to middle price range: ignition electrodes cost CHF 32.92 to 49.95, burner gaskets CHF 12.50 to 51.10 and a combined gas valve CHF 276.84 — around half the price of the equivalent valve from a premium brand in the same catalogue. No original control board is stocked there; a compatible replacement board for older Logamatic controls costs CHF 91.80 at another Swiss retailer.) |
| De Dietrich | ×0.8 | Parts ×0.8 (De Dietrich is a French heating brand that is also available through Swiss specialist retailers. An original control board costs CHF 214.03 at the same retailer as the reference price, roughly a fifth below it — a level typical of volume-oriented brands.) |
| Bosch | ×0.85 | Parts ×0.85 (Bosch, still known in parts of Switzerland under its former name Junkers, belongs to the same group as Buderus and is widely available. Ignition and control components sit in the low to middle range at the same retailer as the reference price: a temperature controller costs CHF 120.71, pilot-gas and burner components CHF 5.58 to 201.36. No control board with a listed price is stocked there, which is why this placement rests on those component prices.) |
| Elco | ×0.95 | Parts ×0.95 (Elco has been one of the best-known brands for oil and gas heating in Switzerland since 1928. Burner and wear parts are available across a wide range at the same retailer as the reference price: blast tubes and burner tubes cost CHF 105.06 to 556.51, ignition electrodes CHF 7.69 to 54.95. No control board with a listed price is stocked there; on average the parts sit close to the reference level.) |
| Brötje | ×1 | Baseline — no parts adjustment |
| Samsung | ×1 | Baseline — no parts adjustment |
| LG | ×1 | Baseline — no parts adjustment |
| Premium tier parts ×1.2 | ||
| Weishaupt | ×1.3 | Parts ×1.3 (In the Swiss heating trade, Weishaupt is regarded as a premium brand for oil and gas burners. The burner control manager, the heart of the burner's electronics, costs CHF 456.19 at the same retailer as the reference price, and so considerably more than a comparable control board from the reference brand. Spare parts for this brand accordingly sit at the top end of this overview.) |
| Viessmann | ×1.3 | Parts ×1.3 (Viessmann is one of the best-known premium brands in the Swiss heating market. An original control board costs CHF 464.33 at the same retailer as the reference price, and so considerably more than the reference part, which matches the brand's premium positioning.) |
| Wolf | ×1.25 | Parts ×1.25 (Wolf is a German brand with a technical, rather high-priced reputation, known in Switzerland for heating and ventilation. At the same retailer as the reference price, its spare parts sit noticeably above average: fans cost CHF 365.18 to 610.01, ignition and flame-sensing electrodes CHF 16.29 to 80.95. No control board with a listed price is stocked there.) |
| Oertli | ×1.3 | Parts ×1.3 (Oertli is a long-established Swiss brand for oil and gas heating with a large base of installed systems. At the same retailer as the reference price, Oertli parts cost considerably more than the equivalent parts from volume-oriented brands: a fan CHF 803.55, a combined gas valve CHF 519.51 against CHF 276.84 for the comparable Buderus valve, a burner thermostat CHF 535.90. Spare parts for this brand therefore sit at the top end of this overview.) |
| Hoval | ×1.2 | Parts ×1.2 (published rates from 1 local repair company) |
| CTA | ×1.2 | Parts ×1.2 (tier median (premium segment, heat pumps and climate technology; the middle level of the evidenced premium brands in this overview). CTA is a Swiss manufacturer of heat pumps, air-conditioning and ventilation equipment with a premium positioning. No public spare-parts prices in Swiss francs are available for this brand.) |
| Daikin | ×1.1 | Parts ×1.1 (Daikin is the world's largest supplier of air conditioners and heat pumps and is widespread in Switzerland too. A control board for a Daikin Hydrobox heat pump in the EHBH/EHVH series costs CHF 311.17 at a Swiss specialist retailer. The reference price, however, comes from a VAT-exempt retailer with large promotional discounts, so part of the price difference is down to the different pricing basis and the real gap is smaller than a plain comparison of the figures suggests.) |
| Mitsubishi Electric | ×1.2 | Parts ×1.2 (With its Ecodan heat pumps and split air conditioners, Mitsubishi Electric is one of the best-known brands on the Swiss market. At a Swiss specialist retailer, accessories cost CHF 60 for filters and CHF 300 to 525 for remote controls, VAT included — a high-priced spare-parts segment. No public prices for this brand's control boards are available, which is why this placement rests on those accessory prices.) |
| Stiebel Eltron | ×1.2 | Parts ×1.2 (tier median (premium segment, heat pumps; the middle level of the evidenced premium brands in this overview). Stiebel Eltron is a German heat-pump specialist with a good reputation in Switzerland. No public Swiss spare-parts prices are available for this brand.) |
| Panasonic | ×1.15 | Parts ×1.15 (tier median (premium segment, air conditioning and heat pumps; the midpoint of the two evidenced brands Daikin and Mitsubishi Electric). Panasonic Aquarea heat pumps and split air conditioners are common in Switzerland. An international mail-order retailer stocks Panasonic climate parts priced in Swiss francs, including a fan motor at CHF 177.17 and a filter at CHF 25.33, but no control board; Swiss specialist-trade prices are not available for this brand.) |
| Alpha Innotec | ×1.2 | Parts ×1.2 (published rates from 1 local repair company) |
| NIBE | ×1.2 | Parts ×1.2 (published rates from 1 local repair company) |

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.
