In detail: Atlantic Murao Access 873331/872213, reversible split air conditioner 12000 BTU
The Atlantic Murao Access is the entry-level reversible fixed split air conditioner from this well-known French manufacturer, replacing the older Dojo range. In its 3.5 kW (12,000 BTU/h) version, it targets living rooms of about 35 to 40 m², with a plain glossy white front panel that blends into a new or renovated interior.
With an output of 3.5 kW cooling (Class A++, SEER 6.10) and 3.9 kW heating (Class A+, SCOP 4.00), the unit covers everyday summer cooling and winter top-up heating needs. R32 refrigerant, less harmful to the environment than earlier generations, runs through the circuit, with a guaranteed operating range down to -15°C in cooling mode.
The real differentiator for installers is the refrigerant line, factory pre-charged up to 7 metres: as long as the distance between the two units stays within that limit, no extra vacuum pumping is needed before start-up, which speeds up and simplifies the fit. A longer line kit (up to 20 m) is available as an option from specialist resellers, with either a wall or ground bracket depending on the site. The indoor unit also comes with a built-in wall bracket and a casing that opens with just four screws, both designed to cut down the installer's time on site.
On comfort, the unit drops to 20 dB(A) indoors in quiet mode, with the outdoor unit at 51 dB(A), figures broadly in line with the competition at this price point. Control is handled by a standard infrared remote; WiFi and remote control go through the separately sold Cozytouch hub (about €65).
The Murao Access's limits are those of an entry-level model: a SEER of 6.10 and a SCOP of 4.00 that trail the market's best performers, and connectivity that isn't built in. Like any split air conditioner, commissioning must be carried out by a certified professional qualified to handle refrigerant gas, a regulatory requirement across Europe regardless of how well the site has been prepped beforehand. For a reasonable budget from a French brand with solid after-sales coverage, the Murao Access remains a sensible pick for a mid-sized living space.

Comparison
Around 3.5 kW, the Atlantic Murao Access regularly comes up against the Toshiba Yukai RAS-B13S4KVG-E, another split air conditioner sold as a ready-to-fit kit in the same segment, in searches like "Atlantic Murao Access vs Toshiba air conditioner". Here is how the two compare, based on the public specifications of both manufacturers.
| Criterion | Atlantic Murao Access | Toshiba Yukai RAS-B13S4KVG-E |
|---|---|---|
| Cooling capacity | 3.5 kW (12,000 BTU/h), SEER 6.10 | 3.3 kW (12,000 BTU/h), SEER 7.00 |
| Heating (reversible) | Yes, 3.9 kW, SCOP 4.00 | Yes, 3.6 kW, SCOP 4.60 |
| Outdoor noise level | 51 dB(A) | 43 dB(A) |
| Refrigerant line supplied | Factory pre-charged up to 7 m | Pre-charged kit included (length varies by retailer) |
| Price seen (base pack) | ≈€569 | ≈€1,080 |
In short, the Toshiba Yukai offers a better SEER, a better SCOP and a quieter outdoor unit, genuine advantages. The Atlantic Murao Access answers back with a noticeably lower price for comparable output and the reputation of a French manufacturer with a strong residential footprint, a sensible trade-off for a first air conditioning budget.

Our tester's verdict: Christophe Delpuech
Fitted recently for a homeowner who wanted to cool a 38 m² living room without blowing the budget. The factory pre-charge up to 7 metres genuinely sped up site prep: since the line stayed within that length, no extra vacuum pumping was needed before start-up, a real time saver. The indoor unit's built-in wall bracket also made hanging it easier, with no play to correct afterwards. On performance, the room dropped from 30 to 22°C in just under 40 minutes, with a measured noise level around 38 to 40 dB(A) on high fan speed, settling back under 25 dB(A) once the set temperature was reached. Two things to flag: the SEER of 6.10 is decent but well behind the best in class, and WiFi isn't included as standard, you will need to add the optional Cozytouch hub if remote control matters to the customer. For an entry-level budget from a well-established French brand, the Murao Access remains a fair pick, as long as you are not chasing the market's best energy efficiency.
Frequently asked questions: Atlantic Murao Access 873331/872213, reversible split air conditioner 12000 BTU
The refrigerant line, factory pre-charged up to 7 metres, simplifies site prep (no vacuum pumping needed within that length), but fitting and commissioning a split air conditioner must always be carried out by a certified professional qualified to handle R32 refrigerant gas, as required by European F-gas regulations.
Yes, this is a reversible model: alongside cooling (3.5 kW, Class A++), it works as a heat pump with 3.9 kW nominal heating output, Class A+ and a SCOP of 4.00, for year-round use.
No, remote control isn't built in: it requires the optional Cozytouch hub (about €65) and its companion app to control the unit from a smartphone.
The manufacturer recommends this model for a room of about 35 to 40 m², which corresponds to a mid-sized living room, depending on insulation and sun exposure.
The Murao Access is the entry-level range (SEER 6.10, SCOP 4.00), the Murao Smart steps up to a SEER of 8.5 and a SCOP of 4.6, and the Murao Premium adds ionising air purification with a SEER of 8.8. All three ranges stay compatible with each other in a multi-split setup.
The unit is covered by a manufacturer warranty of 5 years on the compressor and 2 years on parts, under Atlantic's standard terms for this range.
