🛠What is an HVAC commissioning engineer?
The HVAC commissioning engineer (« metteur au point CVC » in French) is a specialist technician who steps in once heating, ventilation and air conditioning systems have been installed.
Their role is to make sure that every piece of equipment operates as specified.
It is a job that calls for both technical expertise and rigour on site.
What a commissioning engineer does
Start-up
Initial start-up and configuration of HVAC equipment
Air balancing
Measuring and adjusting airflow rates across ductwork systems
Hydronic balancing
Setting water flow rates in heating and chilled water circuits
Measurements and checks
Temperature, humidity and pressure measurements
Commissioning reports
Writing commissioning reports and test certificates
Diagnostics and troubleshooting
Identifying and resolving faults
Required skills and certifications
Technical skills
- ✓ In-depth knowledge of HVAC systems: air handling units (AHU), heat pumps, VRV/VRF, boiler plant, mechanical ventilation
- ✓ Reading ductwork and pipework drawings and schematics
- ✓ Knowledge of standards: DTU 68.3 (French ventilation code), RE2020 (French building regulations), EN 378, NF C 15-100 (French wiring regulations)
- ✓ Use of measuring instruments: balometer (flow hood), anemometer, manometer, thermal imaging camera
- ✓ Controls and BMS (building management systems)
- ✓ Grounding in thermodynamics and fluid mechanics
Mandatory certifications
Electrical clearance
B2V, BR, BC (French electrical safety levels)
Essential for working on electrical control panels and controllers
CACES (French plant operator licence)
R486 (mobile elevating work platforms, MEWPs)
Required on some sites for work at height
Training and qualifications
There is no single diploma. Employers look for a solid HVAC background and, above all, site experience with measuring instruments.
BTS FED (Fluids, Energy, Home automation)
Two-year technical diploma, the most common route into commissioning: HVAC systems, hydronics, control.
BUT Génie thermique et énergie
Three-year university degree (formerly DUT GTE): thermodynamics, fluid mechanics, energy performance.
Professional bachelor in energy and HVAC engineering
A specialisation year after a BTS or DUT, often taken as a work-study programme.
Career change from HVAC maintenance or refrigeration
Many commissioning engineers start as maintenance or refrigeration technicians and learn balancing on site, alongside an experienced engineer.
HVAC commissioning engineer salary
Gross annual salary for an employee, by experience:
Median: €26,900 gross per year. Source: Hellowork, estimate based on published job offers, September 2026. Travel allowances (long-distance assignments) and on-call bonuses come on top, depending on the employer.
As an independent: the commissioning engineers on the Metteur au Point network charge €400 to €450 excl. VAT per day (their published day rates, September 2026).
Career prospects
- ✓ Lead commissioning engineer, in charge of a team on large sites
- ✓ Commissioning manager for a contractor or a major group
- ✓ Project manager (chargé d'affaires) in an HVAC company
- ✓ Independent commissioning engineer, or founder of a commissioning company
Jobs and assignments
Commissioning engineers are in short supply: contractors, maintenance companies and major groups recruit all year round.
- Post your CV: recruiters and companies on the network consult the CV database (jobs, internships, work-study).
- Receive site requests as an independent: installers, design offices and property managers send their commissioning requests directly to the network.

Where do commissioning engineers work?
Commissioning engineers work on all types of buildings.
Start-up vs. commissioning: what's the difference?
Start-up
- Starting the equipment for the first time
- Checking basic operation
- Testing safety devices
- First power-up
Commissioning (testing, adjusting and balancing)
- Fine-tuning of settings
- Balancing of distribution systems (air & water)
- Performance optimisation
- Verifying compliance with the specification
- Writing commissioning reports and records
Frequently asked questions
Q. How much does an HVAC commissioning engineer earn in France?
According to Hellowork (estimate based on published job offers, September 2026), the median gross salary is €26,900 per year: about €22,900 with no experience, €30,900 once experienced and €35,800 at senior level. Independent commissioning engineers on the Metteur au Point network charge €400 to €450 excl. VAT per day.
Q. What is an HVAC commissioning engineer?
An HVAC commissioning engineer is a specialist technician who steps in once heating, ventilation and air conditioning (HVAC) systems have been installed, to set them up, balance them and make sure they perform to the specification. They secure thermal comfort and energy performance in the building.
Q. What does a commissioning engineer do?
Their duties include: start-up of HVAC equipment, air and hydronic balancing, airflow, water flow and temperature measurements, controller set-up, writing commissioning reports and diagnosing faults.
Q. Which certifications does a commissioning engineer need?
The main one is the French electrical safety authorisation (B2V, BR, BC), sometimes together with a CACES licence for mobile elevating work platforms. Qualibat or Qualifelec certifications (French trade qualifications) may also be required.
Q. What is the difference between start-up and commissioning?
Start-up means switching the equipment on for the first time and checking that it basically works. Commissioning goes further: fine adjustment, balancing of the air and water distribution systems, optimisation of settings and verification that the expected performance is achieved.
Q. What training do you need to become an HVAC commissioning engineer?
A BTS FED (French two-year diploma in building services engineering) or a DUT Génie Thermique (thermal engineering) is the usual starting point.
Q. Does a commissioning engineer work alone or in a team?
They generally work independently on site.
Q. What tools does a commissioning engineer use?
Hot-wire anemometer, vane anemometer, micromanometer, balometers (flow hoods), multimeter, hydronic balancing kit... These are the essential instruments for measuring airflow, pressure and electrical parameters on site.
Q. Are commissioning engineers in demand?
Yes. Commissioning engineers are in short supply and in high demand.
Q. How do I find a qualified commissioning engineer?
The metteuraupoint.fr platform connects clients with qualified commissioning engineers across France.
