Cost: split and multisplit air conditioning
Compare proposals covering the same rooms and services. Split and multisplit offers should specify units, connections and associated work; do not assume one arrangement is always cheaper.
Editorial update on 18 September 2026
Compare a complete proposal
Separate equipment, supports, connections, electricity, condensate and commissioning. Identify making good, access equipment and scope limits. If heating is also needed, request performance and coverage under intended conditions without automatically classifying the system as supplementary or primary heating.
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
Is multisplit always cheaper?
That is not established here. Compare offers for the same spaces, services and constraints.
Is a reversible function enough to heat the entire home?
Request an assessment of needs and model performance under the selected conditions. The word reversible does not answer this.
How long does installation take?
Confirm availability, work duration and making good after the visit. No universal duration is guaranteed.
