Quote: split and multisplit air conditioning
E.g.: single-room mono-split air conditioning, 3-room multi-split

Specify rooms to cool and intended use. Attach a plan and proposed unit locations. The installer must assess the configuration; room count alone does not determine equipment numbers or output.
Describe summer comfort needs
Specify overheated rooms and times, shading and ventilation options. Klima-Agence presents these measures to examine before defining mechanical cooling needs.
Specify units and connections
Request indoor and outdoor model references and locations, routes, penetrations and condensate arrangements. Assess noise, maintenance access and any required consents. An available balcony alone is not permission to install.
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.

On quotation
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.
Subsidies and grants
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.
