The Igenix 12000 BTU portable air conditioner UK households choose for year-round comfort is a true 4-in-1: cooling, heating, fan and dehumidifier in one unit. With 3500W of cooling and 3200W of heating it regulates temperature in rooms up to 23m², making it one of the larger portable options for open-plan living rooms, big bedrooms or home offices. At roughly 600 BTU per m² it comfortably handles spaces in the low-20s of square metres. As a single-hose monobloc unit it vents warm air out through the supplied exhaust hose and window kit, so honest expectations matter: it needs an open window or vent to work, and no portable AC is genuinely hoseless. A dual-motor system boosts airflow and efficiency, while the built-in dehumidifier removes up to 41 litres of moisture per day to cut damp. Running cost tracks the cooling load, roughly 90p-95p per hour at around 26p/kWh under full cooling, with the A energy rating and 24-hour programmable timer helping you balance comfort against bills. Three fan speeds and a clear digital display showing ambient temperature keep it simple. In the box you get the air conditioner, window/venting kit, exhaust hose and remote control. A capable all-seasons workhorse for medium-to-large UK rooms.

4-in-1 Portable Air Conditioner, Cooling, Heating & Dehumidifier, 12000 BTU — FAQs
Does the Igenix 12000 BTU portable air conditioner need venting out of a window?
Yes. It's a single-hose portable unit, so it must vent warm air outside using the supplied exhaust hose and window/venting kit. No portable air conditioner can cool effectively without venting the hot exhaust air out of the room.
What room size does this 12000 BTU unit cover?
It's rated for rooms up to 23m², making it suitable for larger bedrooms, open-plan living areas and home offices. At roughly 600 BTU per m², 12000 BTU is well matched to spaces in the low-20s of square metres.
How much does the 12000 BTU portable air conditioner cost to run per hour?
With 3500W of cooling, expect roughly 90-95p per hour at around 26p/kWh when cooling at full power. The A energy rating and 24-hour timer help you reduce this by running it only when needed.
What is the difference between this 12000 BTU model and the 9000 BTU version?
The 12000 BTU unit cools larger rooms up to 23m² with 3500W of cooling and dehumidifies up to 41 litres a day, whereas the 9000 BTU models suit smaller rooms up to around 18-20m². Choose 12000 BTU for bigger or warmer spaces.
What's included in the box?
You get the portable air conditioner, a window/venting kit, an exhaust hose and a remote control, so you have everything needed to set it up and vent it through a window.
