Air conditioner shortage in France: what is happening in 2026?

Every summer, the same scene plays out in France: as soon as temperatures peak at 35°C, air-conditioner shelves empty out, installation lead times explode, and prices climb. In 2026, the AC shortage is no longer a summer anomaly — it has become a structural constraint. Here is what is actually happening, and how to get through it without waiting for the next heatwave.

Key numbers

Main sources: Météo-France (2025 climate report), Uniclima / GIFAM (residential cooling market), Xerfi (residential air-conditioning market), Ademe (AC guide 2024).

Why the shortage is becoming permanent

1. The French climate changes faster than the housing stock

Météo-France recorded 2025 as the second-hottest year ever measured in mainland France, with heatwaves that arrived earlier, lasted longer and spread further. Official projections expect 2003-style summers to be the new normal by 2030–2040. Yet French buildings — stone, concrete, poorly ventilated Haussmannian flats — were never designed for that climate.

2. Historically low equipment rate

About one in four French homes has AC, compared to more than one in two in Italy, over two thirds in Spain, and near-universal coverage in Japan or the US. The catch-up is brutal: every publicised heatwave triggers a wave of purchases and installations the industry struggles to absorb.

3. F-Gas regulation reshuffles the deck

The revised European F-Gas regulation phases out the most polluting refrigerants. R410A is already gone; R32 is being replaced by R290 (propane) for portable units. Those technical transitions temporarily disrupt supply: fewer models available, additional certification costs, and a harsh selection among Asian manufacturers.

4. RGE Fluides technicians are saturated

Installing a fixed AC (split) in France requires the "refrigerant handling" certification (category 1). Qualified technicians are few, in very high demand, and the profession recruits slowly. As a result, most installers are booked solid from June to September.

5. Supply chains remain fragile

Copper (heat exchangers), steel (compressors), electronics and shipping from Asia have all stayed volatile since 2022. Retailers order tightly and refuse to overstock — the first hot week empties the warehouses.

What it changes for households

Three symptoms show up every summer:

• Shelf stockouts — mid-range units (2,500 to 3,500 W cooling) are the first to disappear at Boulanger, Darty, Leroy Merlin or Amazon, often within 48 h of a heat spike.
• Longer install lead times — for a fixed split, realistic delays go from 3–4 weeks in April to 8–10 weeks in July.
• Targeted inflation — remaining models get more expensive (sometimes +15% on the same SKU in two months), and promotions vanish.

Rent, buy or install: which option in 2026?

• Usage < 6 weeks per year, rental flat: renting a portable AC is unbeatable — no landlord approval, no invasive install, pickup at the end of the season.
• Offices, open space, one-off events: same logic on the business side — office rental or event rental.
• Owner, primary residence, recurring use 3+ summers: installing a fixed AC remains the most energy-efficient option — provided you book in winter.
• Compare with other rental operators: ClimLoc vs Kiloutou and ClimLoc vs Boulanger Rental.

How to prepare for summer 2026

1. Book before May. Anything reserved before the first heatwave is guaranteed without markup.
2. Measure your room. Undersized units are inefficient. Rule of thumb: ~100 W cooling per m².
3. Check the hot-air exhaust. Tilt-and-turn windows are the worst case — proper sealing is mandatory for a portable unit.
4. Prefer refurbished. Lower carbon impact, contained price, and often more available than brand-new 2026 stock.
