How does a portable air conditioner work?

A portable air conditioner draws in the room's warm air, cools it via a refrigeration circuit, then releases the warm air outside through an exhaust hose (window kit included). No installation, just plug into a standard socket.

Which BTU rating for which room?

Bedroom 10–15 m²: 7,000 BTU. Lounge 15–25 m²: 9,000 BTU. Large room 25–35 m²: 12,000 BTU. Above 35 m², a fixed split air conditioner is a better fit and more economical to run.

Is a portable air conditioner allowed in a flat or rental?

Yes, no problem at all. No hole in the wall, no landlord or building management approval needed. The window kit fits and removes in 5 minutes without damaging window frames.

Portable air conditioner: the complete guide

The portable air conditioner (also called portable AC or mobile air conditioner) is the easiest way to cool a room without any works. No work on the wall or window frame, no landlord authorisation required: unbox, plug in, evacuate hot air through the window with the supplied kit. Ideal for renters, flats, mezzanines and bedrooms.

Which power should you choose?

The power of a portable air conditioner is measured in BTU (British Thermal Units). For a 10–15 m² bedroom, 7,000 BTU is enough. For a 15–25 m² lounge, 9,000 BTU. For a large 25–35 m² room, budget 12,000 BTU. Beyond that it is better to consider a fixed split air conditioner to save on the electricity bill.

How much does a portable air conditioner cost?

At Climamax, portable air conditioners start at 80€ for entry-level models and rise to €600 for quiet premium versions (Klarstein, Olimpia Splendid, Trotec) with WiFi, touchscreen and dehumidifier mode. Enjoy our special offers and 3× or 4× interest-free payment.

Quiet portable air conditioner for the bedroom

For a good night's sleep, choose a quiet portable air conditioner rated below 50 dB in night mode. The Olimpia Splendid Dolceclima and Klarstein Iceberg models are our bedroom best-sellers. Sleep mode with a progressive reduction in fan speed and a dimmed display so it doesn't dazzle you.

Portable, monobloc, monosplit: are they the same?

The portable air conditioner (or monobloc) is the ancestor of the portable AC: everything is integrated in a single unit with an exhaust hose. The fixed monosplit has two units (indoor + outdoor) connected by a refrigerant pipe; it is more powerful, quieter and more economical in use — but it requires a professional installer and a hole in the wall.
