With Swiss summers getting hotter, many tenants in cities like Zurich, Zug, and Sankt Gallen are wondering: Can I legally install air conditioning in my rental apartment? The answer is yes, but it comes with specific legal and technical considerations. In this guide, we explain your options, costs, and what’s legally required.
Permit and landlord approval usually required.
Exterior modifications (like wall drilling) require permission.
In cantons like Zurich or Geneva, stricter rules apply, often needing medical or energy efficiency justification.
| AC Type | Pros | Cons |
|---|---|---|
Mobile (Monobloc) | Easy setup, no installation, flexible | Noisy, inefficient, vents through window/door |
Split AC | Efficient, quiet, great for multiple rooms | Needs approval, more complex installation |
Heat Pump / Multi-split | Heats & cools, long-term investment | Expensive, strict permit process |
Evaporative Coolers | Low energy use, no exhaust hose | Only work in dry climates, require frequent water refills |
Newer portable models like the Coolzy Pro and SereneLife offer flexibility for windowless or heritage buildings. Some work without vents, using directional airflow. Still, they’re best for personal use in small rooms.
Mobile units: CHF 200–800
Split systems: CHF 600–2,000 (plus installation CHF 650–2,000)
Central or heat pump systems: CHF 7,000–25,000
Use mobile ACs in buildings where modifications are not allowed.
Consider evaporative coolers for low-energy use in dry zones.
For split systems, coordinate with both your landlord and local permit office.
Avoid placing AC exhaust near balconies or shared walls to reduce disputes.

For official context on energy rules, you can reference the Federal Office of Energy of Switzerland, the federal authority overseeing energy and appliance regulations.
Only mobile units are generally allowed without permission. Split or fixed systems usually require both landlord and building authority approval.
Portable or ventless options (like Coolzy Pro or Dreo Evaporative Cooler) work best in rentals where drilling isn’t allowed.
Single-hose units are often less efficient and noisy. Double-hose models or split systems offer better performance and comfort.
Yes, if you’re installing a fixed AC system like a split unit, landlord approval is mandatory. Zurich also has strict regulations, especially in listed buildings. Always check both your rental contract and local guidelines before starting any installation.
