How do brand and quality tier change the repair cost?
Brand and tier adjust the parts portion only — never labour. Value-tier brands — Ariston, Chaffoteaux and Auer — carry some of the lowest parts factors; Saunier Duval, ELM Leblanc, De Dietrich, Chappée, Atlantic, Thermor and Riello form the mainstream core of the French heating market, with Saunier Duval as the price anchor for this list; premium makers — Vaillant, Frisquet and Viessmann — source mainly through the manufacturer's own network (pièces d'origine). On the heat-pump and split-system side, Daikin, Mitsubishi Electric and Toshiba sit in the premium tier, Panasonic, LG and Atlantic in the mainstream core, and Airwell at the value end.

Heat Pump reversing valve replacement: what usually causes it? Estimated
-
Replacing the cycle reversing valve, known as the 4-way valve, with refrigerant recovery and recharging
Pro recommended€400–€1,150
An infrequent but heavy fault, above all on reversible heat pumps more than ten years old whose valve slide seizes: the machine stays stuck in cooling or refuses to defrost. French refrigeration parts distributors show the 4-way valve at €103.98 including VAT for the small references up to €322.05 including VAT for the highest domestic outputs, with one specialist platform quoting a Ranco reversing valve at €282.00 including VAT. To that part are added three to six hours of a refrigeration engineer at €66 to €99 including VAT an hour, that is €60 to €90 excluding tax converted at the 10% rate, a €50 to €80 call-out fixed price and the refrigerant at €60 to €80 a kilo; the national networks moreover treat the 4-way valve as outside their fixed price, with a systematic supplementary quote as soon as the refrigerant circuit is opened. Brazing, vacuum pull-down and recharging are reserved for a certified operator from a firm holding the refrigerant-handling certificate (attestation de capacité).

Replacing the 4-way valve's control coil, without opening the refrigerant circuit
Pro recommended€160–€350
Nine times out of ten, a heating/cooling changeover that no longer happens comes from the 230 V coil that operates the slide, not from the valve body: it is the economical repair a refrigeration engineer looks for first before proposing a complete replacement. The 4-way valve coil is shown at €42.92 including VAT at one spare-parts distributor and €59.26 including VAT at another, the rest of the bill being one to two hours of labour at €66 to €99 including VAT an hour and a €50 to €80 call-out fixed price, which places the total within the range of the electrical repairs recorded in France, €90 to €350 per call-out and €100 to €300 at heat pump repairers. The coil is wired to the outdoor unit's fixed supply, which rules out a private individual doing the work.

How much is a service-call fee for heat pump repair?
Most French companies charge a call-out / diagnostic fee of €80–€170, often credited toward the repair if you go ahead. It is separate from the repair totals above. VAT on French home heating and cooling work is usually the 10% reduced rate for repair and maintenance in a dwelling completed more than two years ago, not the 20% standard rate; some energy-performance improvement work can fall to 5.5%, depending on the equipment fitted and the rules in force. Many independent installers and micro-entrepreneurs also fall under France's small-business VAT exemption (franchise en base de TVA, €37,500 threshold for services) and charge no VAT at all — their invoices carry the note "TVA non applicable, art. 293 B du CGI". Prices displayed to consumers in France are quoted TTC (toutes taxes comprises — all taxes included).
Is it worth repairing a heat pump, 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 heat pump — replacement is often the better value. The calculator's localized totals give you the number to weigh against a new-unit quote.
