List of subclasses


15.8 Contractor – Ventilation

This subclass authorizes construction work that is not the exclusive domain of master pipe mechanics and relates to air circulation or distribution systems for ventilation, air exhaust, air compensation and air conditioning.

It also authorizes construction work relating to ductwork and the installation of pulse air heating units as well as construction work relating to ductwork for pulse air systems providing heating and air conditioning. 

Make sure you have all the required subclasses

Read carefully the definition of this subclass. In addition to subclass 15.8, the contractor might also need other subclasses depending on the work he intends to carry out.

Furthermore, this subclass authorizes construction work relating to pulsed air heating and air conditioning systems, provided the contractor also holds the applicable subclass 15.9 or 15.10 subclass licence. 

Finally, it authorizes similar or related construction work. 

Additional explanations

Amendments to this subclass have been made and are in force since January 16, 2017. To know what the definition of this subclass was in the former regulation, consult the page Amendments to the subclasses concerning heating, ventilation and refrigeration systems.

To view different scenarios illustrating the sharing of work among subclasses governed by the regulatory amendments, refer to the following document: Description of specialized subclasses concerning heating, ventilation and refrigeration units [Fr].  

This subclass includes construction work in subclass 15.7.

This subclass authorizes, without exceeding the regulatory framework, construction work relating to:

  • the installation of pulsed air heating units
  • the installation of residential or commercial kitchen hoods
  • the installation of humidifiers, dehumidifiers, heating and cooling coils, and filters (except for electrical connection work and connection to the hydronic heating, refrigeration or plumbing system)
  • pneumatic conveyance systems
  • the installation of dust extractors or air purifiers connected to equipment other than the building’s system
  • controls and regulators except when the work relates to a heating system. This work can also fall under subclass 17.1.

Note that this subclass does not authorize construction work related to the burners and their supply source nor to work relating to the control and regulation of heating systems.  

Construction work requiring an electrical installation is the exclusive domain of owner-builders holding a subclass 16.0 licence.


  • supervision, inspection, testing and verification work
