Frequently asked questions
How should I choose an air conditioning system in Sion?
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.
