A refrigerant circuit cannot be opened without authorisation
The refrigerant flowing through an air conditioner, R-32 or R-410A in most recent units, is regulated by law. Only a technician holding the certificate of aptitude for handling refrigerants may connect, open, empty or recharge a circuit. The company employing them must itself hold a certificate of capacity. At ClimatisateurPro, both conditions are met: the person working in your home is entitled to do so, and the company stands behind them.
The F-Gas Regulation, applied day to day
European Regulation (EU) 2024/573 sets the rules for using fluorinated gases. In practice, this means recovering refrigerant rather than releasing it into the atmosphere, checking for leaks according to the unit's charge expressed in tonnes of CO2 equivalent, and recording every intervention on the circuit. This information goes into your unit's digital maintenance log, which lets us plan ahead for deadlines as part of our active vigilance.
Skills that go beyond refrigerant
A good air-conditioning technician does more than look after the refrigerant circuit. They know how to dismantle an indoor unit cleanly to disinfect its fan, spot a condensate drain with the wrong slope, check an electrical connection or suggest a more comfortable setting. Our technicians work on wall units, floor consoles, cassettes and ducted systems, in flats and offices alike. They take regular training to keep up with new appliances and new refrigerants.
The right tools for every task
A qualified technician arrives with the equipment that matches their certificate: a refrigerant recovery unit, a vacuum pump, a leak detector and labelled recovery cylinders, but also wash covers, a sprayer and disinfection products suited to coils. This kit travels in their van, which usually means the unit can be dealt with in a single visit, without coming back another day for a missing tool.
People who explain
Being qualified also means being accountable. The technician tells you what they checked, what they did and why, without burying you in technical terms. For an installation, they guide you from choosing the location to commissioning: the process is described on the installation page. And if you are a technician yourself and share this way of working, take a look at our job openings.
