Cost: ducted air conditioning
The quote should separate air treatment, ducts, distribution, controls and ceiling work. Comparing only the unit price hides a significant part of the scope to define.
Editorial update on 18 September 2026
Define zones and services
Describe served rooms, proposed zoning operation and adjustment conditions. Ask how noise, filter access and maintenance are handled. Separate air conditioning work from ceiling construction or repairs; absence of wall units does not guarantee quiet operation.
Clarify equipment follow-up
Identify the refrigerant, applicable inspection and record duties, and qualified contractors. The environment portal explains fluorinated-gas rules; these do not imply the same frequency for every installation.
Check grants for the specific project
A reversible function does not prove Klimabonus eligibility. Check equipment categories, technical conditions and applicable procedures on Guichet before deducting a grant from the budget.

Frequently asked questions
How much ceiling space is needed?
Determine it with the ductwork, equipment and access. Request a project-specific survey or drawing.
Is ducted air conditioning always quieter?
Do not assume so. Ask for characteristics, operating conditions and planned acoustic treatment.
Must the whole house be treated?
Have the desired scope and distribution constraints assessed. This page does not prescribe a number of zones.
