How noisy are portable air conditioners?
Noise levels across our range run from 52dB to 65dB. To put that in context, 52–53dB is roughly equivalent to a quiet conversation, while 65dB is closer to background office noise. Our quieter models (52–54dB) are specifically suited to bedrooms and home offices. If noise is a priority, check the individual product specification for the sleep mode dB rating.
What is the difference between cooling and dehumidifying mode?
Cooling mode actively lowers the air temperature in the room by removing heat and expelling it outside via the exhaust hose. Dehumidifying mode removes moisture from the air without necessarily lowering the temperature significantly — useful during the damp British shoulder seasons when the air feels muggy rather than hot. All units in our range include both modes, with dehumidifying capacity ranging from 14 to 60 litres per day depending on the model.
Can I use a portable air conditioner in a rented property?
Yes — portable air conditioners are ideal for rented properties because they require no permanent installation. You simply position the unit, fit the window venting kit (no drilling required), and plug into a standard 13A socket. When you move out, the unit comes with you. Always check your tenancy agreement if you're unsure, but in most cases no landlord permission is needed.
Are the air conditioners in this range energy efficient?
Every unit in our range carries an A energy efficiency rating — the highest standard available for portable air conditioners. All models also use R290 refrigerant, which has a significantly lower global warming potential than older refrigerants like R410A. Running costs vary by BTU output: a 5,000 BTU model draws around 560–650W, while a 14,000 BTU unit draws up to 1,610W.
Do any models provide heating as well as cooling?
Yes — our 5-in-1 models include a heating function alongside cooling, dehumidifying, fan, and sleep modes. The heating output reaches up to 9,800 BTU (approximately 1,150W), making them suitable for taking the chill off a medium-sized room in autumn or winter. These models represent the best value if you want a single unit that works year-round rather than a separate fan heater and air conditioner.
What size portable air conditioner do I need for my room?
Match the BTU rating to your room size. 5,000 BTU suits rooms up to 12㎡ (small bedrooms), 7,000–9,000 BTU covers 10–28㎡ (standard bedrooms and home offices), and 12,000–14,000 BTU handles larger living rooms and open-plan spaces up to 40㎡. If your room is poorly insulated or south-facing, size up by one step.
Do portable air conditioners need to be vented outside?
Yes — all portable air conditioners need to exhaust hot air outside via a hose. Our units come with a sliding window kit that fits most standard UK sash and casement windows. The hose routes through the kit and vents outside, while the window remains largely closed around it. No permanent installation or drilling is required.
