Tap a star to rate
Lauber IWISA AG from Naters is a building services company with several departments, including heating and cooling, plumbing, kitchens, roofing and sheet metal work, and planning and customer service. Energy consulting sits within the heating and cooling department, which also covers heat pumps. That means replacing a fossil heating system can be handled by the same company that later plans and installs the new system.
The company has been in business since 1933, runs a 24-hour emergency service, and works in both German and French, which makes it accessible for the Upper Valais.
