What changes a Thermor repair bill
- Brand tier — Two class-confirmed product pages, both Thermor Nagano air-conditioning boards, both priced: carte électronique PCB 084436 at 366,54 EUR TTC (0.92x, listed for Unité externe Thermor NAGANO 12500W) and carte électronique mère 084512 at 573,13 (1.43x, listed for Unité cassette Thermor NAGANO 7100W R32). Median ratio 1.1744, rounded to 1.15. Both boards are climatisation hardware rather than gas-boiler boards, and this entry says so openly. The retailer's wider Thermor catalogue includes much cheaper electric-heating and chauffe-eau boards (72,85-220,41 EUR HT listed) which are not used here; several of those would be out of class anyway. Atlantic reference 030455 is the same physical part as a Thermor AEROMAX listing; it is not cited under Atlantic, so the two Groupe Atlantic entries share no citation.
- Parts vs labour — the brand and tier shift the parts price; labour tracks your area's wage index, not the brand.
- The specific fault — a sensor, seal, or valve is far cheaper than a compressor, motor, or control board.
- DIY vs professional — Some Thermor faults (filters, seals, hoses) are DIY-feasible for confident owners; sealed-system and control-board work is a professional job.
