Portable air conditioner with remote control

If you're after a fuss-free way to stay cool, this 12,000 BTU portable air conditioner does the job brilliantly. It's a smart, all-in-one unit that offers cooling, dehumidifying and fan modes - ideal for larger spaces up to 25 sqm. The dehumidifier helps reduce excess moisture in the air, which is especially handy in humid conditions or damp rooms. Fan mode gives you a quick burst of spot cooling when you just need a gentle breeze aimed right where you’re sitting.

It’s simple to install and even easier to use - just plug it in, connect the hose, and you’re good to go.

There’s a digital control panel, three fan speeds, swing mode for horizontal airflow adjustment, and a 24-hour timer so you can pre-cool rooms for your arrival. The sleep mode is designed for night-time comfort - each hour, the set temperature rises by 1°C, helping you stay cool as you drift off without overcooling the room.

With castor wheels, side handles and a compact design, it’s easy to move from room to room. And with a remote included, you’ve got full control without having to get up from the sofa.

Question from Karen: Asked on 12/07/2025 How simple is set up please?

Answer from JimsonGuzman: Answered on 15/07/2025

Setup for the 12000 BTU Portable Air Conditioner with Remote Control is simple and quick. You just plug the unit into a standard power outlet, attach the included exhaust hose to the back of the unit, and vent it out through a nearby window using the supplied adjustable window kit. The window kit fits most standard windows and helps seal the opening. Once set up, you can power on the unit and use the remote control or onboard panel to adjust the temperature and settings. 


It’s simple to install and even easier to use - just plug it in, connect the hose, and you’re good to go.


Thanks!

Question from John Cross: Asked on 12/07/2025 Do all the windows need to be closed when operating?

Answer from JimsonGuzman: Answered on 15/07/2025

Hi, , yes, all windows and doors in the room should be kept closed while operating for optimal cooling performance.


Leaving windows open lets warm air in and cool air out, which reduces efficiency and makes the unit work harder — increasing energy consumption and reducing cooling effectiveness.


Thanks
