Product details & service
What makes this product stand out?
This portable air conditioner needs no installation — set it up, run the exhaust hose to the window, switch it on. The advantage lies in flexibility: no drilling, no specialist installer, no intervention in the building fabric. If you rent, this design is hard to avoid. Performance data: 12,000 BTU, 3,500 watts. A note on setup: the exhaust hose should run as short and straight as possible to the outside, and the window should stay sealed. Otherwise, exactly the warm air the unit just pushed out flows straight back in — and cooling performance drops noticeably. Also on board: Energy efficiency class A.
