In detail: Daikin ATXC35E, connected split air conditioner 12000 BTU
The Daikin ATXC35E/ARXC35E gives access to the Japanese brand, a historic reference in residential air conditioning, at a noticeably more accessible price than its more established Sensira or Perfera ranges. This fixed split air conditioner rated at 3.5 kW (12,000 BTU/h), Class A++ with a SEER of 6.8, comes with built-in WiFi allowing remote control via app with no separate card or module to buy, unlike some older Daikin models.
The unit stands out for its electrostatic filter, which removes airborne dust particles to improve indoor air quality, along with automatic vertical swing of the air outlet louvres for a more even temperature spread across the room. The economy standby mode, said to cut power draw by about 80% when the unit is not actively running, rounds off this energy-efficiency-focused approach.
R-32 refrigerant, now standard across most manufacturers for its lower environmental impact, also equips this model. A fan-only function, without activating cooling, allows more versatile year-round use, for example to simply circulate air on a mild evening.
Like any fixed split air conditioner, made up of an indoor and an outdoor unit connected by a refrigerant line, installing the ATXC35E must be entrusted to a certified professional to handle the refrigerant gas, a cost to plan for on top of the price listed on Amazon. For anyone after Daikin's well-known reliability without paying for its most fully-featured ranges, this model is a particularly well-equipped entry point.

Comparison
Around £550, the Daikin ATXC35E regularly comes up against the Hisense Halo+ 9000 BTU, another budget-friendly connected fixed air conditioner, in searches like "Daikin vs Hisense air conditioner". Here is how the two compare, based on the public specifications of both manufacturers.
| Criterion | Daikin ATXC35E | Hisense Halo+ 9000 BTU |
|---|---|---|
| Cooling capacity | 3.5 kW (12,000 BTU/h) | 2.6 kW (9,000 BTU/h) |
| Connectivity | Built-in WiFi | Built-in WiFi |
| Filtration | Electrostatic filter | Antibacterial evaporator, carbon filter |
| Price observed | ≈£549 | ≈£379 |
In short, the Hisense Halo+ offers a more accessible price for a smaller room, with a focus on air purification. The Daikin ATXC35E provides higher cooling power and the Japanese brand's long-term reliability reputation, for a somewhat higher investment.
Our tester's verdict: Christophe Delpuech
Feedback on this ATXC35E, though less abundant than on older Daikin models, is overwhelmingly positive, with a 4.4 out of 5 rating. Built-in WiFi, with no separate card or module to buy as is sometimes the case on older Daikin units, is cited as a genuinely practical feature by several buyers, offering remote control straight out of the box. The electrostatic filter is also appreciated for its effectiveness against airborne dust, a point regularly raised in reviews focused on indoor air quality. The economy standby mode, said to cut consumption by about 80% when idle, matches the expectations of a manufacturer known for its focus on energy efficiency. As with any fixed air conditioner, installation by a certified professional remains a mandatory step, not included in the unit's listed price. The still-limited number of reviews (35 to date) calls for measured confidence, but the Daikin name, a historic reference in the sector, combined with the feature set on offer at this price point, make it a very credible option.
