What Size Air Conditioner Do You Need?
The most important factor is matching the BTU output to your room size. As a guide: 5,000 BTU suits rooms up to 12㎡ (a small bedroom), 7,000–9,000 BTU covers 10–28㎡ (a standard bedroom or home office), and 12,000–14,000 BTU is suited to larger living rooms and open-plan spaces up to 40㎡. Choosing too small a unit means it will run constantly without reaching your target temperature — choosing too large wastes energy.
Portable vs. Fixed: Which Is Right for a UK Home?
Portable air conditioners are the most practical choice for most UK homes. They require no permanent installation — just position the unit, route the exhaust hose through a sliding window kit (included with most models), and plug in. This makes them ideal for renters, period properties, or anyone who wants flexibility to move cooling between rooms. Fixed split systems offer quieter operation but require professional installation and planning permission in some properties.
Should You Choose a Model with WiFi Control?
WiFi-enabled models (controlled via the TUYA or Smart Life app) let you set your target temperature before you get home, adjust settings from bed, and monitor energy use remotely. If you're cooling a bedroom or home office where convenience matters, app control is worth the modest price premium. For a utility room or garage, a standard remote-control model will do the job.
What About Dehumidifying?
All units in our range include a dehumidifying function — useful during the damp British shoulder seasons when the air feels muggy rather than hot. Dehumidifying capacity ranges from 14 to 60 litres per day. Higher-capacity models are better suited to conservatories, basements, or rooms with poor ventilation where moisture build-up is a persistent issue.
Do You Need Heating as Well as Cooling?
If you want a single unit that works year-round, look for our 5-in-1 models with a heating function. These provide up to 9,800 BTU of heating output — enough to take the edge off a cool autumn evening in a medium-sized room — alongside full cooling and dehumidifying capability. A practical investment if you're replacing both a fan heater and a cooling unit.
Energy Efficiency and Running Costs
Every unit in our range carries an A energy efficiency rating and uses R290 refrigerant — a low global warming potential coolant that is increasingly the standard for responsible manufacturers. In practical terms, our 5,000 BTU models draw around 560–650W, while 14,000 BTU units draw up to 1,610W. Running a mid-range 9,000 BTU unit for 8 hours a day at current UK energy rates costs approximately £1.00–£1.50 per day — comparable to a fan heater but with far greater cooling effect.
