Wettingen is a few minutes from our base in Nussbaumen. We work here regularly – in apartment buildings, single-family homes and commercial premises.
In a municipality with many apartment buildings and closely spaced housing, the challenge is rarely the technology indoors – it is where the outdoor unit goes. Two things decide that:
With condominium ownership – very common in Wettingen – the facade, roof and balcony parapet generally count as common property. For a unit on the building envelope you therefore need a resolution of the owners’ association, not just your own agreement. Raise it early at a meeting; retrospectively it becomes harder.
As a tenant you need the written consent of your landlord. Settle at the same time what applies when you move out.
In the typical Wettingen housing stock the buildings often stand close together and balconies face one another. The federal Noise Abatement Ordinance sets limits that must be met, particularly at night – and a unit pointing straight at a bedroom window causes friction even when the measured values are formally correct.
In practice a good solution can almost always be found: a different orientation, decoupling against structure-borne noise, an acoustic hood, or a night mode with reduced fan speed. What matters is planning this before installation rather than repairing it afterwards.
Have a brief word with your immediate neighbours before anything is fitted. It costs ten minutes and, in our experience, prevents more conflict than any technical measure applied afterwards.
Wettingen lies in the canton of Aargau, where a permanently installed system is not automatically subject to a building permit. In residential zones a notification to the municipality is often sufficient; a full building application tends to be required where the outdoor unit is clearly visible or the building stands in a core or conservation zone. The municipality decides – clarify it before you buy. Background in our guide to permits and regulations.
