In detail: Daikin Sensira FTXC50D + RXC50D, reversible split air conditioner 18000 BTU
The Daikin FTXC50D/RXC50D is a reversible fixed split air conditioner from the Sensira range, the most accessible entry point in the Japanese brand's catalogue, sold here as a pack with a ready-to-fit 7-metre refrigerant line kit. With a cooling output of 5.1 kW (18,000 BTU/h, Class A++, SEER 6.45) and 5.6 kW heating (Class A+, SCOP 4.42), it targets large rooms up to 150 m³, roughly 40 to 50 m²: an open-plan living room, a through lounge, or a large bedroom.
Like the rest of the Sensira range, the unit favours substance over gimmicks: a flat, unobtrusive front panel, an air filter that catches airborne particles, automatic vertical louvre swing to spread air across the room, and a turbo mode to reach the target temperature faster, in both summer and winter. R-32 refrigerant, less harmful to the environment than the R-410A it's gradually replacing, runs through the circuit, with a 1 kg charge on the RXC50D outdoor unit.
Remote control, via app, local network or the internet, is optional here rather than standard: it requires adding a separate Daikin WiFi module, unlike more recent models from the brand where WiFi comes built in. On the noise side, the indoor unit drops to 30 dB(A) in quiet mode and stays under 47 dB(A) at full fan speed, with the outdoor unit at around 51 dB(A), figures broadly in line with the competition at this power level.
The supplied kit, 7 metres of 1/4" and 1/2" copper pipe, electrical cable, a wall bracket for the outdoor unit and a condensate drain hose, makes site preparation easier for the installer. Commissioning still has to be carried out, like any split air conditioner, by a certified professional qualified to handle the refrigerant gas: that's a regulatory requirement across Europe, not a mere suggestion.
For a reasonable budget given the output on offer, the FTXC50D remains a sensible pick for anyone after Daikin's well-known reliability on a large room, as long as you accept that standard connectivity and the brand's latest design touches are reserved for its higher ranges (Comfora, Perfera).

Comparison
In the 18,000 BTU segment, the Daikin FTXC50D regularly comes up against the Toshiba Seiya+ 18, another 5 kW split air conditioner well regarded for its value for money, in searches like "Daikin vs Toshiba 18000 BTU air conditioner". Here is how the two compare, based on the public specifications of both manufacturers.
| Criterion | Daikin FTXC50D | Toshiba Seiya+ 18 |
|---|---|---|
| Cooling capacity | 5.1 kW (18,000 BTU/h), SEER 6.45 | 5.0 kW (18,000 BTU/h), SEER 7.0 |
| Heating (reversible) | Yes, 5.6 kW, SCOP 4.42 | Yes, 5.4 kW, SCOP 4.4 |
| Connectivity | WiFi optional (separate module) | Built-in WiFi |
| Indoor noise level (min) | 30 dB(A) | 26 dB(A) |
| Installation kit | 7 m included in the pack | Sold separately depending on retailer |
In short, the Toshiba Seiya+ 18 offers a slightly higher SEER and built-in WiFi as standard, two genuinely modern advantages. The Daikin FTXC50D answers back with its brand's reputation for longevity and after-sales support, and above all with a 7-metre line kit already included in the pack, a real saving on installation extras.

Our tester's verdict: Christophe Delpuech
Fitted recently for a homeowner who wanted to cool a large 45 m² living room without breaking the bank. The 7-metre kit supplied made site prep noticeably easier: copper pipes, cable and bracket were already in the box, only the exact drilling length needed adjusting on site. Once both units were connected and the line was vacuum-pumped, cooling kicked in fast, the room went from 29 to 22°C in about half an hour, with a measured noise level around 44 to 47 dB(A) on high fan speed, matching the manufacturer's figures. One thing to watch on this model: the wall bracket supplied for the outdoor unit felt a bit light for a 39 kg condenser, so a reinforced bracket is worth planning if the wall isn't perfectly flat. Another minor gripe, no WiFi as standard means ordering the module separately if remote control matters to the customer. Over time though, the compressor behaves exactly as you'd expect from Daikin, quiet and steady. Solid value for power and reliability on a large room, as long as you budget for those two small extras.
Frequently asked questions: Daikin Sensira FTXC50D + RXC50D, reversible split air conditioner 18000 BTU
The supplied kit (7 m copper line, cable, wall bracket) makes site preparation easier, but fitting and commissioning a split air conditioner must always be carried out by a certified professional qualified to handle R-32 refrigerant gas, as required by European F-gas regulations.
Yes, this is a reversible model: alongside cooling (5.1 kW, Class A++), it works as a heat pump with 5.6 kW nominal heating output, Class A+ and a SCOP of 4.42, for year-round use.
No, unlike more recent Daikin ranges, WiFi is not built in on the FTXC50D: it requires a separately purchased compatible Daikin module to control the unit from a smartphone.
The manufacturer recommends this model for spaces up to 150 m³, roughly 40 to 50 m² depending on ceiling height and insulation, which corresponds to a large living room or an open-plan reception area.
The pack includes 7 metres of 1/4" and 1/2" copper pipe to connect both units, an electrical connection cable, a wall bracket for the outdoor unit and a condensate drain hose, on top of the indoor unit, outdoor unit and remote control.
The generation letter mainly changes connectivity: newer models (E) build WiFi in as standard, while the FTXC50D (D) only offers it as an option via a separate module. Thermal performance (output, SEER, SCOP) stays close between generations.
