As a Systems Technician in Heating, Ventilating and Air Conditioning (HVAC), you will be responsible for the installation, maintenance, repair, and troubleshooting of heating, cooling, and ventilation systems in Department of National Defence facilities across Canada. You will work with complex mechanical equipment, ensuring that all systems operate safely, efficiently, and in compliance with federal regulations and environmental standards. Your work directly supports the operational readiness of military installations by maintaining comfortable and safe working environments for personnel.
Your day-to-day responsibilities will include performing preventive and corrective maintenance on HVAC equipment, diagnosing system malfunctions, replacing components, conducting system testing and adjustments, and maintaining detailed records of all work completed. You will collaborate with other trades professionals, facilities management teams, and external contractors to ensure seamless operation of building systems. You may also be involved in upgrading aging systems, implementing energy-efficient solutions, and training junior technicians.
This role is typically performed in military bases, offices, hospitals, and other DND facilities, working both indoors and in mechanical rooms. The work environment may involve physical demands such as lifting heavy equipment, working in confined spaces, climbing ladders, and exposure to various temperatures and weather conditions. You must be comfortable working independently and as part of a team, and willing to respond to emergency calls when systems fail.

Post-secondary education or equivalent experience relevant to the position
Training
To qualify for this position, you will typically need a high school diploma or equivalent, combined with a recognized apprenticeship certificate or technical diploma in HVAC systems or mechanical trades. Many candidates complete a 4-5 year apprenticeship program through provincial trade schools or equivalent private training institutions. You must obtain or be willing to obtain the appropriate provincial mechanical trade certification or license required in the province where you work.
Professional certifications that strengthen your candidacy include EPA (Environmental Protection Agency) refrigerant certification, which is often mandatory for handling refrigerants. Additional certifications in building automation systems, energy efficiency auditing, and CAD software are advantageous. The DND provides on-the-job training and professional development opportunities, including advanced technical courses, leadership training for those pursuing supervisory roles, and continuing education in emerging HVAC technologies. You will be expected to maintain your certifications throughout your career and participate in mandatory safety and environmental compliance training.
Entry Plans
Entry into this career with the Department of National Defence typically occurs through competitive staffing processes. The most common pathway is through public job competitions advertised on the Government of Canada's official job board (jobs.gc.ca), where applicants with the required qualifications and credentials are evaluated. The DND may also maintain recruitment pools of qualified HVAC technicians to fill positions more rapidly as vacancies arise across facilities.
If you are already part of the federal Public Service, you may be able to transition into this role through internal competitions or lateral moves, particularly if you have relevant mechanical or trades experience. Student programs and apprenticeship opportunities may also be available, allowing you to earn while you learn through formal training partnerships. Prior military service, including as a Regular Force or Reserve Force member with HVAC experience, can facilitate entry into civilian positions. We recommend regularly checking jobs.gc.ca and the DND careers website for current opportunities in your region.
Part-Time Options
Part-time and flexible work arrangements for Systems Technicians in HVAC are typically limited due to the nature of the role, which often requires full-time presence to respond to system failures and maintain scheduled preventive maintenance programs. However, the DND recognizes the importance of work-life balance and may offer flexibility in scheduling where operationally feasible.
Remote work is not applicable to this position, as the role requires hands-on technical work with physical equipment and systems located at specific facilities. That said, some administrative or planning tasks associated with the role may be completed off-site. Shift work, including evening, night, or weekend shifts, may be required to ensure that critical building systems are monitored and maintained continuously. Emergency on-call duties may also be part of the position, particularly for personnel stationed at key military installations. Discuss specific flexible work options with your hiring manager and local facilities management team, as arrangements vary by location and operational needs.
