Buying Guide
Cooling capacity (BTU) and room size
Match the unit’s BTU rating to the room you want to cool. As a rough guide, around 8,000 BTU suits a small bedroom (up to ~20 m²), 10,000–12,000 BTU covers medium rooms (20–35 m²) and 14,000 BTU+ is needed for larger spaces; undersizing means poor performance, oversizing wastes money and energy.
Venting and installation
Portable air conditioners need to exhaust warm air, usually via a window kit; single-hose models are simpler but less efficient than dual-hose designs, which draw outside air for intake. Check your window type, the length of the exhaust hose and whether you can install and store the kit without damaging frames or causing draughts.
Energy efficiency and running costs
Portable units can be thirsty to run, so look for high energy-efficiency ratings, lower kW consumption and modern refrigerants such as R32 or R290 where available. Consider approximate running costs in GBP — a more efficient machine may cost more up front but save money over a hot summer, especially with rising electricity prices.
Noise level and features
Noise is important in bedrooms and living spaces; check the dB rating (lower is quieter) and use modes like ‘sleep’ or ‘eco’ for reduced noise and power. Also consider useful features such as dehumidifier/fan modes, timers, remote control or app connectivity and washable filters for easier maintenance.
Portability and build
Look for sturdy castors, a comfortable carry handle and a manageable weight if you plan to move the unit between rooms. Also check drain options (auto-evaporation vs manual drain), filter accessibility and warranty length — long warranties and good customer support are valuable in the UK market.
Frequently Asked Questions
What is the best portable air conditioner in 2026?
There’s no single best model for everyone; the top choice depends on room size, noise tolerance and budget. In 2026 look for units that balance a suitable BTU rating, high energy efficiency (R32/R290 where possible), low noise (sub‑50 dB for bedrooms) and reputable UK support from brands stocked by Currys, John Lewis or AO.
Is a portable air conditioner worth buying in the UK?
Yes for people who need a temporary or movable cooling solution — portable ACs are ideal for renters, those who can’t fit a fixed unit, or to cool individual rooms. For whole-house cooling or the most efficient option, a fixed air-conditioning system or heat-pump solution will usually perform better and be cheaper to run long term.
Which portable air conditioner offers the best value for money?
Best value balances purchase price, efficiency and features: mid-range 10,000–12,000 BTU models from established brands often offer the sweetest spot. Compare energy use (kW), noise levels and included accessories; promotions at Currys, AO and Amazon UK frequently shift the value picks by season.
De'Longhi vs Honeywell - which should I buy?
De'Longhi models (Pinguino line) are often praised for quieter operation and better efficiency, while Honeywell tends to provide more affordable, straightforward units with good availability. Choose De'Longhi for quieter, longer-term use and Honeywell if price and ease of purchase are your priority.
How much does it cost to run a portable air conditioner in the UK?
Running costs vary by unit efficiency and usage, but expect a typical portable AC to draw about 1–1.5 kW while cooling; at UK electricity prices this can cost several pounds per hour. Use eco modes, timers and set the thermostat sensibly to control bills — using a fan or dehumidifier mode will usually be cheaper than full cooling.
Can a portable air conditioner cool a whole house?
No — portable ACs are designed to cool single rooms or small open-plan areas; they’re not effective for whole-house cooling. For multiple rooms you’ll either need several units or a fixed multi-split/ducted system.
What maintenance do portable air conditioners need?
Regular tasks include cleaning or replacing filters, emptying manual condensate trays if present, checking exhaust hoses for kinks and storing the unit properly over winter. Follow the manufacturer’s guidance to keep performance and avoid mould or odours.
Are dual-hose portable air conditioners better than single-hose models?
Dual-hose units are typically more efficient because they use one hose to draw outside air and another to exhaust it, reducing negative pressure and heat draw from outside. They can be bulkier and slightly more expensive, but are usually a better choice for larger or frequently used rooms.
