Buying Guide
Cooling capacity (BTU) and room size
Match the unit’s BTU rating to the size of the room — undersized models will struggle, oversized units short‑cycle and waste energy. For most UK living rooms you’ll commonly look at 8,000–14,000 BTU for single rooms and 14,000+ BTU for larger or open‑plan spaces.
Dual‑hose advantage and room layout
Dual‑hose portable air conditioners draw intake air from outside and exhaust separately, which maintains neutral pressure and cools faster than single‑hose units. They work best where you can fit both hoses to a window kit and in larger or well‑used rooms where efficient cooling matters.
Energy efficiency and running costs
Check the unit’s energy efficiency (EER or seasonal rating) and estimated power draw so you can estimate running costs on your electricity tariff. Dual‑hose models tend to be more efficient at cooling, but higher BTU models will still use more power — factor both purchase price and likely kWh use into your decision.
Noise level and placement
Portable air conditioners contain the compressor and fan inside the living space so noise varies between models; look for decibel ratings and reviews. If noise is important for bedrooms or study areas, favour lower‑dB units or models marketed as ‘quiet’ and plan placement away from seating or sleeping areas.
Installation, drainage and maintenance
Ensure the unit includes a suitable window kit for UK sash or casement windows, and check whether it is auto‑evaporating or needs periodic draining. Also consider filter access for cleaning, the length and diameter of hoses, and whether spare parts and service are readily available locally.
