Regulatory Labels for Refrigerant Leaks

What to Do in Case of an Air Conditioning Leak?

First and foremost, it is not possible for an individual to install a heat pump or repair an AC unit by themselves. When an installation contains refrigerant, it is necessary to call a professional technician who will determine the source of the leak using specific tools (refrigerant leak detector, scales, transfer pumps, etc.).
An individual can purchase replacement parts for air conditioning themselves and then have them installed by a refrigeration technician, or they can try to detect the problem without actually working on the installation. By directly purchasing the correct AC replacement part, you avoid having the technician make multiple visits (diagnosis, part purchase, repair), and thus you won’t be charged multiple times.

The Certification of the Technician

During their visit, the refrigeration technician who comes to repair the AC or heat pump (PAC) must certify their service by placing a specific label on the installation.
There are two types of labels:

• The blue sealing control label, which indicates that the air conditioning installation is in good condition at the time of the technician's visit. The AC or PAC contains no leaks, and it is not necessary to add refrigerant.
• The red marking label, on the other hand, specifies that the installation must be repaired before being restarted. It is also not possible to recharge the AC with refrigerant gas, as it would escape again upon use of the air conditioning unit.

Following the placement of the sealing control label, the technician must record the information related to their visit in their intervention log. Each refrigerant leak must be documented, as most refrigerant gases are highly polluting.
