France homeowners face heat‑pump installation costs and mandatory maintenance fees

Heat‑pump owners in France must comply with energy‑regulation rules that require a qualified professional to inspect the refrigerant circuit and keep a maintenance log. Annual service contracts typically cost €80‑€150 for air‑air units and €150‑€350 for air‑water or geothermal systems, helping preserve warranty coverage and system efficiency.

For a 100 m² home, the total price of a heat‑pump system ranges from €4,000 to €25,000 depending on technology. Air‑water models, the most common, usually fall between €10,000 and €18,000 installed. Air‑air units start around €4,000, while geothermal or water‑water solutions can exceed €20,000. The French MaPrimeRénov’ programme may subsidise up to 40 % of eligible costs based on household income. Approximately 600,000 heat‑pump units are installed each year in France, reflecting a rapidly expanding market.
