As a Technologist - Heating, Ventilation, and Air Conditioning (HVAC) with the Department of National Defence, you will be responsible for maintaining, troubleshooting, and repairing complex HVAC systems that support military operations and defence facilities across Canada. You will work with heating systems, cooling equipment, ventilation networks, and climate control installations in diverse environments ranging from barracks and offices to specialized operational facilities. Your technical expertise ensures that critical building systems operate reliably and safely to support the Canadian Armed Forces' mission.
In this role, you will perform preventive maintenance, diagnose system failures, and conduct repairs on mechanical and electrical components of HVAC equipment. You will read and interpret technical drawings, blueprints, and specifications; maintain detailed maintenance records; and collaborate with other trades professionals and facility managers. Your work will directly impact the comfort, safety, and operational readiness of military personnel and the protection of sensitive equipment that relies on precise climate control.
You will work in various settings including mechanical rooms, rooftops, and inside occupied facilities. The work environment may involve heights, confined spaces, exposure to refrigerants and other substances, and the need to follow strict safety protocols. This is a hands-on position that combines technical problem-solving with practical mechanical skills in a structured military facility environment.

Post-secondary education or equivalent experience relevant to the position
Training
To qualify for this position, you typically need a high school diploma or equivalent, plus specialized training in HVAC systems. Most candidates have completed a formal HVAC technician apprenticeship program through a provincial trade school or community college, which usually takes three to four years. You may also enter with equivalent practical experience gained through previous employment.
Essential certifications include a provincial HVAC certification or equivalent trade qualification recognized across Canada. Many positions require certification as a refrigeration mechanic and may involve EPA (Environmental Protection Agency) certification for handling refrigerants, depending on the province. You must be willing to obtain and maintain security clearance at the level required for your posting.
Once hired, you will receive on-the-job training specific to DND systems, facilities, and procedures. The Canadian Armed Forces supports ongoing professional development through technical courses, equipment manufacturer training, and advancement opportunities in specialized HVAC systems. You may pursue additional certifications in building automation systems, energy efficiency, or supervisory roles as your career progresses.
Entry Plans
Entry into this career with DND occurs through several pathways. The primary route is through a Government of Canada job competition advertised on the Public Service Commission (PSC) website and the DND Civilian Workforce Careers portal. Competitions may be local, regional, or national depending on staffing requirements and facility locations.
You may also enter through the Federal Student Work Experience Program (FSWEP) if you are a full-time student in a relevant HVAC or trades program, providing valuable work experience and potential conversion to a permanent position upon graduation. Some positions are filled through priority hiring processes that consider veterans or Canadian Armed Forces members transitioning to civilian roles.
Lateral movement is possible if you are already a federal public servant in a related trade or technical position. The Canadian Armed Forces may also conduct recruitment drives at provincial trade schools and through apprenticeship programs. Once hired, you begin as an employee at the appropriate classification level based on your qualifications and experience, with opportunities for advancement through demonstrated competency and experience.
Part-Time Options
Part-time opportunities for HVAC Technologists are limited in DND due to the nature of facility maintenance requirements and on-call emergency repair obligations. However, some flexibility may exist depending on the specific facility and staffing situation. If part-time arrangements are available, they are typically negotiated on a case-by-case basis through your manager and HR department.
Remote work is generally not applicable to this position, as the role requires hands-on work with physical HVAC systems located throughout military facilities. However, administrative components of the work—such as documentation, record-keeping, and training—may occasionally be performed off-site.
Flexible work arrangements may include flexible hours or shift schedules where operationally feasible, particularly if your facility operates extended hours. Many DND facilities require 24/7 building system support, which may involve shift work, on-call rotations, or overtime during maintenance projects or system emergencies. Discuss specific flexibility options with the hiring manager during the recruitment process, as arrangements depend on facility needs and operational requirements.
