ExploreAbout this exam
The HRAI Ozone Depletion Potential (ODP)/Ozone Depleting Substances (ODS) Refrigerant Handling certification is a Canadian credential offered through the Heating, Refrigeration and Air Conditioning Institute of Canada (HRAI), a non-profit national trade association founded in 1968. HRAI describes the program area as "Canada's Ozone Layer Protection Awareness," and its refrigerant course family includes the ODP/ODS Course and the Low GWP/A2L Refrigerants Course, with delivery partners listed separately. The credential is aimed at HVACR technicians, contractors, wholesalers and others who handle refrigerants and need to demonstrate awareness of ozone-depleting substances and refrigerant management responsibilities. Related HRAI navigation includes ODP Renewal Certification, a Certification Status Lookup, Replacement ODP/ODS Wallet Cards, and a Refrigerant Courses Login, which suggests the credential is renewable and verifiable. This guide is independent study material and is not affiliated with, endorsed by, or sponsored by HRAI; always confirm current requirements directly with HRAI at [email protected] or 800-267-2231. HRAI's public pages do not publish the exam length, passing score, fee, format or validity period for this certification, and the dedicated ODP certification page currently returns "File Not Found." Candidates should therefore prepare around the published course learning outcomes and assessment requirements rather than assumed logistics. Because HRAI states that technical courses focus on specific areas of HVAC knowledge and practice and advises reviewing learning outcomes, prerequisites and assessment requirements, a sound study plan is to confirm the course page details first, then build knowledge of ODS identification, ozone depletion science, refrigerant handling and recovery practice, and the transition toward low-GWP and A2L refrigerants before attempting the assessment.
What you'll study
About HRAI ODP Refrigerant Handling preparation
Is this the same as the ODP/ODS Refrigerant Course on HRAI's site?
HRAI lists an ODP/ODS Course alongside a Low GWP/A2L Refrigerants Course under its ODP/ODS Refrigerant Courses heading, plus a Refrigerant Courses Login and French-language equivalents. Treat the course and the certification as linked but distinct: confirm on the course page which assessment leads to certification.
How long is the exam, and how many questions does it have?
HRAI's public pages do not state the question count, time limit, or format for this certification, and the dedicated ODP certification page currently returns a File Not Found error. Do not rely on secondhand figures; contact HRAI at [email protected] or 800-267-2231 to confirm before booking.
What score do I need to pass, and what does it cost?
The passing score and fee are not published in HRAI's available public material, so any number you hear is unverified. HRAI directs training and certification questions to [email protected]. Ask about the current fee, assessment requirements, and any member or renewal pricing at the same time.
How do I renew, and how do I replace a lost wallet card?
HRAI's navigation includes ODP Renewal Certification and Replacement ODP/ODS Wallet Cards, which indicates renewal and card replacement are supported. Eligibility conditions, renewal timing, and any validity period are not stated publicly, so confirm your personal status through HRAI rather than assuming a fixed cycle.
How can an employer verify that I hold the certification?
HRAI provides a Certification Status Lookup and a searchable HRAI Canadian Certification Database that accepts last name, city, certification number, certification type, and province. Note that the published certification-type list is dominated by residential design and ventilation credentials, so confirm with HRAI how ODP status appears.
What topics should I study first?
Start with the science: what makes a substance ozone-depleting, how ODP is used to compare refrigerants, and why recovery and handling discipline matters. Then move to refrigerant management practice and the low-GWP and A2L transition, since HRAI pairs the ODP/ODS Course with a Low GWP/A2L course.
Is the course or exam available in French?
Yes, HRAI lists French-language equivalents, including Certification pour la manipulation des halocarbures and Formation sur les réfrigérants A2L et à faible PRG, with a separate French course login. Confirm with HRAI which language versions include the assessment and whether both languages use the same requirements.
Where do I find course dates and the registration process?
HRAI publishes a Course Catalogue, a 2026/27 Schedule at a Glance, and a registration guide under its training pages. Begin there, then verify the specific ODP/ODS course page for prerequisites, materials, and assessment details, because HRAI advises reviewing those before enrolling.
What mistakes cause people to fail or waste a booking?
The most common problems are studying from outdated or unofficial summaries, skipping the published prerequisites and assessment requirements, and assuming unverified exam logistics. HRAI explicitly advises reviewing learning outcomes, prerequisites, and assessment details first, so confirm those before you pay or schedule.
