Buying Guide

Cooling capacity and room size

Choose a unit sized for the area you want to cool โ€” portable ACs are rated in BTU/h (or kW). For a typical double bedroom used by a couple, look for around 8,000โ€“12,000 BTU (โ‰ˆ2.3โ€“3.5 kW); too small and the unit will struggle, too large and it will short-cycle and waste energy.

Noise level

Portable units sit in the room so noise matters, especially at night. Aim for models that list sound levels below 50 dB on their lowest setting for bedroom use; quieter compressors and โ€˜sleepโ€™ modes make a big difference to a coupleโ€™s comfort.

Energy efficiency and running cost

Portable ACs are generally less efficient than fixed airโ€‘source heat pumps or split systems, so check the EER/COP ratings and estimated power draw. Consider typical electricity prices in the UK and look for units with eco modes, timers and good insulation of the exhaust hose to keep running costs sensible.

Portability and installation

Look at weight, castor quality and how the exhaust hose/window kit fits your home โ€” many couples in rented flats need a no-fuss installation that wonโ€™t damage sills. Singleโ€‘hose machines are simpler but less efficient than dualโ€‘hose designs; check whether a window kit for sash or tilt windows is included or sold separately.

Features and controls

Decide which extras matter: dehumidifier function, fan-only mode, sleep timers, remote control, app/voice control and washable filters. For shared bedrooms, programmable timers and quiet night modes are particularly useful so the unit cools before you sleep and stays unobtrusive overnight.

Frequently Asked Questions

What is the best portable air conditioner for couples in 2026?
There isnโ€™t a single best model for everyone, but for most couples a 10,000โ€“12,000 BTU (โ‰ˆ2.9โ€“3.5 kW) portable AC that balances low noise (<50 dB), good EER and features like a sleep mode is ideal. Brands that consistently deliver this mix in the UK market include De'Longhi for quieter operation, LG for smart features, and value-focused European brands such as Klarstein.
Is a portable air conditioner worth buying in the UK?
Yes, if you rent, need a temporary solution or want to cool a single room without installing a permanent system. Theyโ€™re less efficient than fixed systems, so for wholeโ€‘home cooling or longโ€‘term use a split system or heat pump is usually better value.
Which portable air conditioner offers the best value for money?
Best value is typically found in midโ€‘range units priced around ยฃ300โ€“ยฃ450 that offer ~10โ€“12k BTU, decent energy ratings and noise levels under 50 dB. Look for models sold by Currys, AO or John Lewis with good warranties and readily available spare filters.
De'Longhi vs LG โ€” which should I buy?
Choose De'Longhi if you prioritise quieter operation and solid build quality for bedroom use; choose LG if you want smart connectivity, app control and often sleeker styling. Compare specifications (BTU/kW, noise in dB and energy rating) rather than brand alone.
How big of a portable AC do I need for a double bedroom?
A double bedroom of about 12โ€“18 mยฒ typically needs roughly 8,000โ€“12,000 BTU (โ‰ˆ2.3โ€“3.5 kW) depending on ceiling height, insulation and sun exposure. If the room gets a lot of direct sun or you have high ceilings, err towards the higher end.
How much does it cost to run a portable air conditioner in the UK?
Running costs vary by unit and electricity price, but as a rough guide: a machine drawing about 1.0โ€“1.2 kW running for eight hours at a typical UK rate could cost roughly ยฃ2โ€“ยฃ3 per day. Check each modelโ€™s power draw and use economy settings to reduce bills.
Can a portable AC cool two rooms for a couple?
Portable ACs are designed to cool one main space; they can moderate adjacent areas if doors are open, but cooling two separate rooms effectively is unlikely. For couples who want to cool multiple rooms regularly, a multi-split or portable units in each room are better solutions.
Where should I buy a portable air conditioner in the UK?
Major retailers such as Currys, John Lewis, Argos and AO, plus Amazon UK, stock a broad range and often include customer reviews, delivery and returns. For peace of mind consider John Lewis or Currys for longer warranties and better inโ€‘store advice.
