2026 renter cooling guide

Portable split ACs that fit European flats

Start with the window, not the BTU number. We check outdoor placement, noise, weight, stock and real setup videos.

Setup finder

Start with the awkward part: your window.

Pick where the outside box can sit. Then adjust room size, heating and budget to see which units still make sense.

Best match for this setupMidea PortaSplit 12K

Strong cooling, heat-pump mode and no-drill setup make it the easiest serious alternative to a wall split. The catch is the 32.5 kg indoor unit and whether your window can hold the outdoor box safely.

Install notes

Tilt-and-turn windowGermany, Austria, Netherlands and many EU apartments

Usually the easiest renter setup, as long as the gap and bracket angle are realistic.

French balcony doorRenters with narrow exterior railing access

Often workable, but the guide must show how the outdoor unit is restrained.

Balcony or terraceMost high-power mobile split systems

The most forgiving setup. It gives bigger systems enough air and somewhere to drain.

Roof windowAttic bedrooms and Velux-style rooms

Needs its own guide because bracket angles and rain protection vary a lot.

UK casement windowUK renters comparing PortaSplit against monoblock units

Do not assume continental bracket examples apply to UK casement windows.

Fixed wall pass-throughOwners and long-term commercial installs

Useful for specialist systems, but it is no longer a no-drill renter setup.

Watch first

Do not trust the brochure until you see the bracket.

The videos show the messy parts: window gaps, outdoor placement and how big the unit looks in a real room. The source cards underneath keep the specs and owner threads close by.

Where to buy

Stock is local. Treat each country separately.

A model can be easy to find in Germany and gone in France the same week. This section keeps the likely retailers separated so price tracking can stay honest.

Germany / Austria

Best place to start for DACH stock checks and tilt-turn window advice.

MediaMarkt
Saturn
Amazon DE
Otto
specialist HVAC shops

France

Heatwaves can empty stock quickly, so French prices need their own watchlist.

Amazon FR
Leroy Merlin
Dealabs

Switzerland

Good for Argo and Midea owner reviews. Keep CHF pricing separate from EUR pages.

Galaxus
Digitec
Dantherm
Aktobis

United Kingdom

UK casement windows make bracket guidance more important than raw cooling specs.

Method

How we rank a portable split.

Window fit is scored before headline BTU.
A split hose path matters because it avoids the negative-pressure problem of monoblock units.
Indoor comfort noise and outdoor neighbour noise are judged separately.
Official specs are paired with owner threads, videos or professional coverage.
Stock and prices should be refreshed during every heatwave update.
