The special thing about air conditioner without outdoor unit

The air conditioners from Raumluft24 are monobloc wall air conditioners. This means that you do not have to mount a disturbing outdoor unit on your house facade. Only two ventilation openings are necessary for the supply and exhaust air, which can be completely closed with our supplied cover flaps when the air conditioner is not in operation. Another advantage is that the complete installation can be done inside the room where you want to use the air conditioner. Thus, no external scaffolding on the house wall is necessary, which saves you effort and costs!

Our air conditioner installation kit

When you buy your air conditioner, Raumluft24 will provide you with all the necessary utensils.

You only need to have the appropriate tools to hand: A core drill with a 16cm attachment is used for the air openings in the house wall (exceptions: Florence model and Naples model 20cm). You will also need a spirit level and, if necessary, a ladder.

Our wall-mounted air conditioners without outdoor unit are installed on the inside of an exterior wall. If there is no suitable exterior wall, we also offer alternatively Ventilation boxes an.
Our air conditioners are installed horizontally or vertically, depending on the model. Installation of the air conditioners is possible both near the floor and at head height. We recommend the optional optical cover for the underside of the air conditioner for installation at head height. You can order this from us by telephone. Make sure that there is a power outlet near the selected location. Our air conditioners require a normal power connection and are delivered to you ready to plug in!
