Ducted air conditioning: price, benefits and who it's for
By the Aircadia team
A ducted air conditioning system costs on average between €8,000 and €12,000 installed for a 100 m² home on the French Riviera. Reversible and almost invisible — only slim supply grilles stay in view — it delivers even, room-by-room air. It’s the most discreet and comfortable solution, but also the heaviest to install.
Key takeaways
- 2026 price: from €6,000 (apartment) to €18,000 (large villa) installed, i.e. 30 to 60 % more than an equivalent multi-split.
- Ducted is not just for new builds: it’s feasible in a renovation as soon as you have accessible attic space or enough height for a dropped ceiling.
- It does not consume less than a multi-split: the technology is the same air-to-air heat pump. You choose it for discretion and comfort, not energy savings.
- Like any split, installation requires a certified technician (F-Gas refrigerant handling certificate).
What is ducted air conditioning and how does it work?
Ducted air conditioning is a centralised reversible air-to-air heat pump. Unlike a wall-mounted split, its indoor unit isn’t in the room: it’s hidden in the attic or a dropped ceiling. From there, a network of insulated ducts distributes air to discreet supply grilles in each room. Only those grilles remain visible.
The big advantage is zoning: with motorised dampers, you set a different temperature room by room (or zone by zone), from a central thermostat or an app. In summer it cools, in winter it heats — a single, invisible unit for the whole house.
What is the price of ducted air conditioning in 2026?
The price of ducted air conditioning depends mostly on floor area, the number of zones and how complex the duct run is. Here are the ranges seen in 2026 from installers (equipment + installation, excluding building the dropped ceiling itself) — these are market orders of magnitude, not a regulated public tariff:
| Home | Indicative installed price | Zones |
|---|---|---|
| Apartment 50–70 m² | €6,000 – €9,000 | 1 – 2 |
| House 100 m² | €8,000 – €12,000 | 2 – 3 |
| Villa 150 m² | €12,000 – €16,000 | 3 – 4 |
| Villa 200 m² and over | €15,000 – €20,000 | 4 and over |
On top of this you may need to build the dropped ceiling if there isn’t one (budget €40 to €80 per m² of ceiling affected). Conversely, in a new build, integrating ducted from the start is far cheaper. To place these figures against other solutions, see our guide to air conditioning prices in Nice.
Note: a reversible air-to-air system, ducted included, does not qualify for MaPrimeRénov’, which is reserved for air-to-water and geothermal heat pumps. The grants you can actually claim are detailed in our 2026 grants guide.
Ducted or multi-split: which should you choose?
This is the real decision point. A multi-split links several wall units to one outdoor unit; ducted hides everything in the ceiling. The table below sums up the real differences.
| Criterion | Ducted | Multi-split |
|---|---|---|
| Indoor visibility | Discreet grilles only | One wall unit per room |
| Indoor noise | Very low (unit in attic) | 19 to 30 dB per unit |
| Installed price (100 m² home) | €8,000 – €12,000 | €5,000 – €9,000 |
| Works involved | Dropped ceiling + ducts | Drilling + wall mounts |
| Renovation | Depends on attic / height | Easy anywhere |
| Room-by-room control | Zoning (dampers) | Per unit |
| Access for maintenance | Harder (attic) | Easy |
| Consumption | Equivalent | Equivalent |
Let’s bust a stubborn myth: ducted does not consume less than a multi-split. Both rely on the same air-to-air heat pump, with comparable efficiency (SEER/SCOP) at equal range. A poorly insulated duct run can even cause small losses. You choose ducted for its aesthetics and its even, silent comfort, not to save on bills. If you’re still weighing configurations, our single-split or multi-split guide rounds out the picture.
Can ducted be fitted in a Riviera villa renovation?
Yes — and here’s another myth to correct: ducted is not reserved for new builds. It’s perfectly doable in a renovation, on one condition: having room to house the unit and the ducts. Two favourable cases on the Riviera:
- Accessible attic (villa, single-storey house with a loft): the ideal situation — the unit and ducts fit there without losing living height.
- A dropped ceiling is possible: you generally need 30 to 50 cm of ceiling depth for the most common ducted unit. Under a standard 2.50 m height that can be a drawback; low-profile ducted units (≈ 20 cm) exist for tight cases.
Without an attic or ceiling margin — common in an older Nice apartment — the multi-split stays simpler and cheaper. Ducted comes into its own in a villa or a high-end renovation, where discretion matters: it’s the same trade-off we detail in choosing air conditioning for a Riviera villa. As with any split, the installation handles refrigerant and must be entrusted to a certified technician (F-Gas certificate), which secures the warranty and correct commissioning.
FAQ — Ducted air conditioning
How long does a ducted air conditioning installation take?
Usually 2 to 5 days for a house, against 1 to 2 days for a multi-split. The job is longer because the duct network has to be run, the supply grilles fitted and, where needed, the dropped ceiling built. In a new build, integrating it into the structure cuts both the time and the cost.
Is ducted air conditioning quieter than a wall-mounted split?
Yes, inside the living spaces. The noisiest part, the unit, is banished to the attic or dropped ceiling: all that’s left is the light hush of the grilles. It’s one of ducted’s main selling points, prized in bedrooms and in the 06’s high-end villas.
Does ducted qualify for grants like MaPrimeRénov’?
No. Like any reversible air-to-air system, ducted is not eligible for MaPrimeRénov’, which is reserved for air-to-water and geothermal heat pumps. Some occasional local grants or a reduced VAT rate may still apply depending on the case: the detail is in our 2026 grants guide.
Can a ducted system heat a whole house in winter in Nice?
Yes. Being reversible, ducted heats the entire home, and the Riviera’s mild winters keep the air-to-air heat pump at excellent efficiency. In a well-insulated house it can serve as the main heating; in a poorly insulated home, a back-up remains wise during the rare cold snaps.
