Cost: heat-recovery ventilation
Compare unit, ducts, terminals, penetrations, acoustic treatment, condensate drainage and settings. Include building finishes and maintenance. Exchanger efficiency is not the saving percentage on the whole bill; no local average price is published.
Editorial update on 18 September 2026
Compare equipment and adaptations
Separate unit, accessories, ducts, terminals, penetrations, dropped ceilings and reinstatement. Identify omitted rooms and work assigned to another contractor.
Check included measurements
Price settings, balancing, airflow records, user instruction and grant documentation. Clarify whether building airtightness testing and any correction are included.
Assess running costs
Request fan consumption in the planned mode, filter prices and maintenance scope. Compare assumptions over equal periods rather than catalogue efficiency alone.

Frequently asked questions
Is higher efficiency enough to choose?
Compare useful airflow, electricity, noise, ducts and maintenance too.
Can it fit without a dropped ceiling?
Assess routes; general feasibility is not a plan for your home.
Do all filters need the same replacement interval?
Follow model instructions, alerts and contamination checks.
Is it compulsory in every renovation?
Check project-specific requirements. A grant condition is not a universal obligation to use this technology.
