Which Daikin monosplit wall air conditioner is right for your room?

A Daikin monosplit wall unit cools in summer and heats in winter with a heat pump for a single room: one indoor unit linked to an outdoor unit, quick installation and low consumption thanks to the most mature Japanese inverter and R-32 Bluevolution refrigerant. The range covers 9000 to 24000 BTU, with more than 270 configurations and prices from about 384 euros. For most living rooms the 12000 BTU Siesta (ATXF35F), the best seller, is the right pick. Browse the full Daikin range or all monosplit wall air conditioners.

The room you can never cool down

The attic bedroom that turns into an oven in July, the south-facing living room where the fan only moves warm air, the office where the heat kills your focus. It is usually one specific room ruining your days, not the whole house, and for that the monosplit wall unit is the simplest, most affordable answer: sorted in a few hours, with no major building work.

The most popular Daikin series

The Sensira series is the gateway to Japanese quality, while the Siesta remains the best seller for its fair balance of price and efficiency. Above sits the Perfera All Seasons, the flagship up to A+++ with real care for clean air, and the award-winning Stylish design. All use R-32 Bluevolution refrigerant and run as a heat pump.

How many BTU per room

The wrong size gets expensive: too much power keeps switching on and off and wastes electricity, too little never cools.

  • 9000 BTU: bedrooms and studies up to about 25 sqm, for cool, quiet sleep, such as the Sensira FTXC25B or the Siesta ATXF-E;
  • 12000 BTU: living rooms up to about 35 sqm, the most chosen size, with the Siesta ATXF35F or the Perfera FTXM35R;
  • 18000 BTU: open spaces or very sunny rooms up to about 45 sqm;
  • 24000 BTU: large rooms that struggle to cool.

How much does it cost to run?

This is the question that stops almost everyone. The Daikin inverter modulates the power instead of switching on and off, so it uses far less than an old unit; with R-32 refrigerant and an energy class up to A+++, the bill stays under control even with cooling on all afternoon.

It heats in winter too

Because it is a heat pump, the same unit warms the room in the mid-seasons within minutes, often for less than an electric heater running for one room. For hot water instead, see the heat-pump water heaters.

Daikin and the connected home

With the Wi-Fi module you turn the cooling on from your phone before you get home and find the room already cool, or control it by voice through the Onecta app. Find all compatible models among the smart air conditioners for Alexa and Google Home.

Daikin versus other brands

Daikin is the Japanese benchmark for reliability and clean air: against Mitsubishi Electric it leans on a mature inverter and a wide service network, while a brand like Hisense costs less for the same size. To compare comfort, also look at Samsung, LG and Haier.

Incentives, warranty and support

Buying a high-efficiency heat-pump unit may qualify for energy-renovation incentives depending on the schemes in force: keep your invoice and paperwork and check the current conditions. Every unit ships with the official Daikin warranty, delivery across the country and ClimaVantage support in choosing size and kits. For several rooms, look at the wall air conditioners as multisplit or a trial split wall system, and check the deals on all air conditioners.

Frequently asked questions

Which Daikin air conditioner for a small bedroom?

Will leaving it on send my bill through the roof?
