What Missenard Climatique does

Missenard Climatique (legal entity: Missenard Quint B) is a French family-owned intermediate-sized enterprise (ETI) specializing in génie climatique — the design, installation, and lifecycle maintenance of HVAC, plumbing, industrial refrigeration, and building automation systems. The company traces its roots to the Quint & Flamant firm founded by Joseph Quint in the 19th century, with a decisive inflection in 1926 when polytechnicien André Missenard joined and introduced scientific methods of measuring thermal comfort (notably the 'température résultante' and 'degré Missenard' concepts still referenced in international standards). Today the company serves builders, healthcare facilities, industrial manufacturers, local authorities, and commercial enterprises across France, organized around two service pillars: Installation/Travaux (new build and renovation) and Exploitation/Maintenance (recurring service contracts, multi-technical management, and energy performance contracts).

The company operates a national network of 31+ autonomous agencies staffed by qualified technicians, supported by an internal GMAO Mission computerized maintenance management system and a 6-month Missenard Académie apprenticeship program that addresses France's HVAC technician shortage. The technical portfolio spans heating (boilers, heat pumps, biomass, geothermal, district heating substations), air conditioning (VRV/DRV, roof-top, chilled water), ventilation and air treatment (including Legionella prevention), plumbing, industrial refrigeration, and GTC/GTB building automation. Revenue is generated through three streams: one-time installation projects, recurring maintenance and exploitation contracts (including 10-year energy performance contracts), and professional services billed at standard hourly rates (€80 HT for engineers, €60 HT for technicians). Pricing is quote-based, with overtime billed at 150% and weekend/holiday/night work at 200% of base rates.

The company is led by two of André Missenard's granddaughters following generational succession, and is consistently ranked among France's top construction-sector firms (206th in Le Moniteur's 2025 Top 1000). Customer concentration is moderate and spread across healthcare (Hôpital de Calais, Hôpital de Douai, AHNAC), pharmaceutical (Aptar Pharma, Bayer Shering), automotive (PSA La Janais, Scania France), insurance (AXA), government (Ville de Baisieux, Ville de Rennes), education, retail, and aerospace. Operations are entirely domestic (France only), with no disclosed international footprint, no external institutional investors, and no M&A activity in the available data.
