Your project in the canton of Valais

Valais follows the Rhône valley from Brig to Lake Geneva, with side valleys climbing up to mountain resorts. The canton is bilingual: French-speaking Lower Valais, around Sion, Martigny and Monthey, and German-speaking Upper Valais, with Brig and Visp. On the hillsides, vineyards surround villages of stone houses and old wooden granaries. Crans-Montana and Zermatt are home to chalets, holiday flats and hotels; in Zermatt, where cars are not allowed, transporting materials requires special arrangements. At altitude, snow and sunshine influence building techniques and the working season. Wherever you live in Valais, you can write your request in English. For a chalet, a traditional mazot or an alteration in an old town, check with your municipality whether approval is needed. Give the municipality and postcode and, in a resort or at altitude, access periods and transport arrangements to the building.

  • For a chalet in a resort, note the altitude, the state of the road in winter and your availability for the work.
  • In Upper Valais, say whether you are happy to communicate in German.
  • For a village house among the vineyards, describe access via the lanes and the space for unloading materials.

Ventilation and air conditioning in the canton of Valais

Valais offers strong contrasts, from the sunny Rhône plain to high-mountain resorts. In Sion and Martigny, summers that are among the hottest in Switzerland make air conditioning attractive for flats and offices, especially in heavily glazed recent buildings. In Crans-Montana, chalets and second homes need ventilation that limits damp during absences and provides healthy air when the occupants arrive. Cellars and wine producers on the vineyard slopes must safely remove fermentation gas. In Upper Valais, around Brig, hotels and shops are modernising their kitchen extraction systems. Before installing an outdoor unit on a chalet, consult the municipality about what is permitted.

  • For a chalet in a resort, plan maintenance outside the season so that it does not disrupt your stays or rentals.
  • In a winery cellar, ask for gas detection linked to the ventilation of the vat room.

Frequently asked questions

How should I choose an air conditioning system in Valais?

Consider the number of rooms to cool, their exposure to sun and the space available for the outdoor unit. Split systems, multi-split systems and reversible heat pumps suit different needs. Ask the installer about noise levels and maintenance.

How do ventilation and cooling requirements differ?

Ventilation addresses air exchange, while cooling manages room temperature; a project may need one or both. Describe occupancy, moisture concerns and heat exposure. Ask the installer to assess air distribution, noise, controls and the space required before recommending a system.

What should I compare in ventilation and air conditioning quotes?

Compare equipment, distribution routes, controls and installation alongside any drainage or electrical work. Ask who checks applicable procedures and permissions for the chosen location. Clarify commissioning, maintenance access and user instructions so proposals cover a functioning system rather than equipment supply alone.

How should I prepare for the ventilation and air conditioning visit or work?

Collect room plans and existing system information, and note access to ceilings, balconies or roofs. Describe spaces that must remain in use. Agree locations and cable or duct routes before installation, with relevant owner or property permissions checked for the project.
