Clean air, quiet comfort, all year round
The Carrier CYRA 18000 BTU (CYRA18K) is a smart wall-mounted split system that cools in summer and heats in winter from one sleek indoor unit. Its 3D DC Inverter delivers A++ cooling efficiency, and its heat pump keeps working down to -20°C outside.
Built-in Wi-Fi lets you control and schedule it from your phone. Triple-action filtration, an ionizer and a self-cleaning cycle keep the air fresher, while Wind Avoid Me keeps draughts off you.
Intelligent Cooling & Heating: Whether it's a July heatwave or a frosty January morning, CYRA adapts its output to the room. Gear, ECO and Sleep settings trim running costs, and Follow Me reads the temperature at the remote, so comfort is measured where you are sitting.
The details
Fast and powerful cooling & heating: Stay comfortable all year round, no matter the weather. The 3D DC Inverter varies its speed to match demand, cooling quickly in summer and heating reliably in winter — even when it’s -20°C outside. Turbo mode gives an extra boost when you need the room comfortable fast.
Control your energy use: Gear mode lets you choose 50%, 75% or 100% output to suit how much cooling or heating you actually need. ECO and Sleep modes trim consumption further, and standby draw is just 1 W.
Control from anywhere with Wi-Fi: Built-in Wi-Fi connects CYRA to your home network. Switch it on, change modes and set schedules from your smartphone, at home or away — so you come home to a room that’s already the right temperature.
Cleaner, fresher air: Silver ion, active carbon and cold catalyst filters work with an ionizer to help reduce dust, odours and fine particles. A filter reminder tells you when it’s time to clean them.
Self-cleaning for a fresher unit: After use, the Active Clean cycle uses steam to help lift dirt from the indoor coil, then dries it out — helping prevent mould and musty odours and cutting routine maintenance.
Draught-free comfort: Wind Avoid Me directs air away from you, so you feel the temperature, not the draught. 3D airflow moves the louvres up, down and side to side to spread air evenly and avoid hot and cold spots.
Comfort where you are: Follow Me uses a sensor in the remote control to read the temperature where you’re sitting, so CYRA adjusts to you rather than to the wall it hangs on.
Built-in heat pump, all year round: With an A++ cooling rating (SEER 7.4) and A+ heating (SCOP 4.1, average climate), CYRA keeps your home comfortable in every season while keeping running costs low.
Ultra-quiet operation: Silent mode takes the indoor unit down to just 20 dB(A) — quiet enough for bedrooms and home offices.
Frost protection and peace of mind: 8°C heating mode keeps an empty room or holiday home above freezing. Refrigerant leak detection, self-diagnosis, auto restart, voltage protection from 168 V to 264 V and an anti-corrosion coated control board help it last.
Eco-friendly efficiency: R32 refrigerant has around a third of the global warming potential of older R410A and transfers heat efficiently. With A++ cooling and A+ heating ratings, CYRA keeps your home comfortable using less energy.
