What Charpentier does
Charpentier SAS is a family-owned climate engineering (Génie Climatique) company headquartered in Brétigny-sur-Orge, Île-de-France, founded in 1953 and currently led by third-generation Director General Guillaume Charpentier. The company designs, installs, operates, and maintains heating, ventilation, air conditioning, plumbing, and renewable energy systems for tertiary, industrial, public authority, and residential copropriété clients exclusively within the Île-de-France region. With an integrated in-house Bureau d'Études Techniques (design office) and a workforce of approximately 70 employees, Charpentier manages more than 1,000 sites, holds 700 active maintenance contracts covering 3,500 installations, and performs 12,000+ interventions annually across 35 municipalities.
The company's technology stack centers on conventional HVAC engineering augmented by GTB/GTC/Télégestion building management and remote control systems, a GMAO TWIMM computerized maintenance management platform, and energy performance services that valorize Certificats d'Économie d'Énergie. It delivers new construction and rehabilitation projects alongside 24/7 preventive and corrective maintenance, and offers an energy supply (Fourniture d'énergie) service line to local authorities and condominiums. Notable projects include climate engineering for the Préfecture de Police de Paris (BSPP base), SDIS 91 fire station in Brétigny-sur-Orge, Groupe Scolaire Vilgénis in Massy, Climb Up Paris (France's largest climbing gym), Printemps, MK2 Cinemas, and multiple regional hospitals.
Charpentier's revenue model is split roughly evenly between one-off Works & Construction (Travaux) projects, which represent approximately half of revenue, and recurring Services/Exploitation-Maintenance contracts that have grown to represent the other half since the 1990s. Pricing is not publicly disclosed and is project-based for works and contract-based for maintenance, with energy supply adding a third recurring revenue stream. The company maintains a balanced public-private client mix and reaches approximately 550,000 inhabitants through municipal and building contracts. Annual revenue has stabilized above €15 million since 2017, and the company remains wholly family-controlled with no external institutional investors or parent company.
