Dear all,

I am looking to either rent or buy a house in Freienbach, and one requirement that I understood can be challenging is having a split unit AC.

Please do not explain to me that I do not need it. I have lived in much colder climates, and my body react differently than most to heat and cold. What I am unlikely to ever need here is heating, but I absolutely must have an AC in this climate, and it needs to be strong (portable won't do).

I searched the forums and got conflicting results regarding there either being a law against AC, the former being an urban legend, de facto existance of personal AC installation sales in Zurich, and claims of regulation that requires permission from the municipality, or other apartments in a building, to install one.

This is all quite confusing unfortunately.
Does anyone have personal experience actually installing private house AC in Switzerland? Does anyone know what is the process to do so in Zurich area or Freienbach specifically?
If I go for a house, rather than an apartment, is it easier (as then I don't need consent from other apartments in the building)?

Cost is not a problem. Cost of electricity is not a problem. I am looking for power in terms of cooling, and the ability to sustain a pleasant temperature of no more than 16 degrees regardless of weather outside.
If medical reasons can help, I can use my allergies as a reason, as a modern AC has air cleansing and anti allergenic properties. If having a business helps, I can operate a dummy micro business in my house.
Basically, any advise, especially from experience, on how to actually obtain a proper AC is most welcome.
