Common questions
Not sure what you need?
That’s exactly what the free consultation is for.
Here are a few useful answers before we speak.
What is a monoblock air conditioner?+
It’s a fixed air-conditioning unit that contains its main components in one indoor cabinet. It connects directly through an outside wall using two air ducts.
Does it really need no outdoor unit?+
Yes. There is no separate outdoor condenser, but the indoor unit still needs to be installed on a suitable external wall with openings for airflow.
What can you see on the outside of the house?+
Typically, two discreet ventilation grilles are visible on the outside wall. Their exact appearance and position depend on the selected unit and your property.
Can it heat my home too?+
Many monoblock models can provide heating as well as cooling. We’ll confirm whether this is supported by the unit recommended for your room.
Will a monoblock unit work in my home?+
That depends on the room, the available external wall, access, electrical requirements and any property restrictions. A video consultation is a good first step to assess the options.
