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.

Ductwork & Vents vent / register replacement: what usually causes it? Estimated
-
Replacing a self-regulating extract terminal (WC or bathroom)
DIY possible€60–€160
The return grille of a warm-air network has no equivalent in French homes: what is replaced here is the ventilation extract terminal, a very common task after a facade renovation, water damage or simply when the terminal yellows. The tradesperson's fixed price starts at €60 including VAT for a single-flow terminal, removal of the old one and a function check included; the terminal alone is found from about ten euros. This floor is distinctly lower than a heating engineer's call-out charge because this is a ventilation or electrical job, not a boiler visit. Nothing here is regulated, and the operation is within a private individual's reach.

Replacing a humidity-controlled terminal or a high-flow kitchen terminal
DIY possible€110–€260
One special case to be set aside first: on a gas-linked ventilation system (VMC gaz), which also serves to remove the boiler's combustion products, the terminal is part of the safety arrangement and its replacement falls to a qualified heating engineer. On a conventional ventilation system, by far the most frequent case, the operation remains within a private individual's reach. The extra cost compared with a self-regulating terminal comes from the part itself, dearer in the humidity-controlled version and in Ø125 or Ø150 for the kitchen, and from the frequent reworking of the spigot when the diameter changes. The listed tradespeople quote up to €220 including VAT for this type of terminal, call-out included, and the repair guides put a terminal replacement at between €100 and €200.

How much is a service-call fee for ductwork & vents 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 ductwork & vents, 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 ductwork & vents — replacement is often the better value. The calculator's localized totals give you the number to weigh against a new-unit quote.
