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.

Air Handler control board replacement: what usually causes it? Estimated
-
Replacing the electronic board of the mechanical ventilation unit
Pro recommended€360–€590
A typical fault of type B humidity-controlled ventilation units and of heat-recovery units, whose controller manages the airflow rates, the humidity sensors and the bypass; it often occurs after a thunderstorm or a power surge when the supply is restored, which damages the electronics of the electronically commutated motors. Contrary to a widespread idea, the board is not a small part: the manufacturer sells the board of an InspirAIR unit at €286.82 including VAT and that of a Dee Fly at €209.59, and a parts distributor shows the board for the Dee Fly and Modulo hygro at €202.50 excluding VAT, that is €243.00 including VAT — three references that bracket the materials at between €209 and €287. To that is added the job itself, billed at €150 to €300 including VAT by a national repair network, call-out and labour included, the electronic board being one of the parts that this fixed price explicitly excludes; on a heat-recovery unit, resetting the airflow rates after the exchange adds to the time spent. The top of the range matches proprietary brand boards and units buried in the loft. The module is connected to the fixed 230 V supply and to low-voltage sensors: the exchange is done by a professional. The bill comes under the 5.5% rate on a heat-recovery ventilation unit or a humidity-controlled single-flow one and under the 10% rate on a self-regulating single-flow one, in a dwelling completed more than two years ago.

Replacing or repairing the electronic board of the air conditioning indoor unit
Pro recommended€290–€850
This line does not deal with the mechanical ventilation unit covered just above but with the indoor unit of an air conditioner or an air-to-air heat pump, whose board has nothing in common with that of a ventilation unit: the two pieces of equipment are repaired separately and at different prices. On wall-mounted and ducted indoor units, the control board is the most common electronic fault, often signalled by a flashing code and a machine that no longer answers the remote control. The price depends first on the type of machine: €150 to €450 including VAT for a new board on a residential single-split, €250 to €600 including VAT on a multi-split, a cassette or a console, and beyond €700 on variable-flow systems. Repairing the existing board is a widespread practice in France: €39 including VAT for the diagnosis fixed price, then €150 to €250 including VAT for a simple overhaul and €250 to €400 including VAT for a heavy repair, with twelve months' warranty. Another price list puts board replacement at €300-900 excluding VAT, that is about €330 to €990 including VAT. On top comes the repairer's labour for the removal, the refitting and the settings, billed at €60 to €70 an hour by a comparison site that does not state a rate; a repair network that itemises its quotes bills the hour at €60 excluding VAT, that is €66 including VAT at the 10% rate applicable to maintenance work in a dwelling completed more than two years ago. The board drives the refrigerant circuit and the unit's 230 V supply: the replacement is reserved for the professional.

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