Alberta's refrigeration apprenticeship: the 4-period AIT program (1,560 hours plus 8 weeks of school per period), the higher entrance bar, the Gasfitter Class B that comes with it, wages, and the Red Seal exam.
Applies in: Alberta
A refrigeration and air conditioning apprenticeship in Alberta is an employer-first path into a compulsory, well-paid trade with a double ticket at the end. Get hired by an HVAC or refrigeration contractor willing to sponsor you, register the apprenticeship education agreement through AIT's MyTradesecrets service, then work four periods of paid on-the-job hours (1,560 per period) interleaved with 8-week classroom blocks and a theory exam each period. In the final period you write the interprovincial Red Seal exam (70% to pass); per SAIT, graduates also earn Gasfitter – Class B. You finish as a certified journeyperson in a trade whose Alberta median sits at $43.00 an hour — and the Red Seal endorsement lets you carry that ticket anywhere in Canada.
SAIT states it plainly: certification is required to work in this trade — you must be a registered apprentice working under the guidance of a certified journeyperson, or a certified journeyperson yourself. The ALIS occupational profile backs it with the statute: under Alberta's Skilled Trades and Apprenticeship Education Act, you must hold a certificate recognized by AIT or be a registered apprentice to install, maintain, repair, or overhaul refrigeration or air conditioning systems or their component parts in the province. Job Bank's national profile (NOC 72402) agrees — Alberta is on the compulsory-certification list. The practical consequence: you cannot start earning hours informally and sort out the paperwork later. Your hours only count once an apprenticeship education agreement ties you to a sponsoring employer, and working the trade outside that structure is not permitted.
The official minimum from AIT (published via SAIT, which notes entrance requirements are monitored and set by AIT) is English 30-2, Math 30-3, and Physics 20 or Chemistry 20 — or a pass mark in all five GED/CAEC tests, or a pass on the AIT entrance exam. This is a step above the requirements for trades like plumbing or welding, and it reflects the content: period 1 opens on enthalpy and gas laws, the vapour compression cycle, and electrical theory with series, parallel, and series-parallel circuits plus magnetism. SAIT's recommended bar adds related career and technology studies (CTS) courses.
You must also be a resident of or primarily work in Alberta, and hold Canadian citizenship, permanent residency, refugee status, a valid CUAET visa, or a post-graduation work permit. You must be at least 16, and you need a sponsoring employer before you can register. If you are still in high school, Alberta's Registered Apprenticeship Program (RAP) lets you start banking apprenticeship hours before graduation.
This is the step that starts the clock. Your hours only count once an apprenticeship education agreement ties you to a sponsoring employer:
The sponsor hunt is a job search in every sense: our job hunting guide walks through Job Bank, Canadian resume conventions, and the NOC codes (72402 for refrigeration and air conditioning mechanics) you will use on applications.
The official structure from SAIT's AIT-aligned program: 1,560 hours of on-the-job training plus 8 weeks of classroom instruction and a theory exam per period, for four periods of roughly a year each. The classroom content builds deliberately:
The on-the-job side runs through the full trade scope: installing, maintaining, repairing, and overhauling industrial, commercial, and residential refrigeration and air conditioning systems — measuring, cutting, and joining pipe with welding and brazing equipment, recharging systems with refrigerant, recovering and handling refrigerants, troubleshooting gas-fired equipment, and calibrating gas-related controls. Blocks are delivered at SAIT (Calgary) and NAIT (Edmonton).
Two notes that matter. First, each period ends with a theory exam you must pass to advance — SAIT requires no less than 50% in each course with at least a 65% average overall, plus a passing mark on the AIT exam. Second, you are an employee the whole way through. Apprentices are paid by their employer while learning on the job, and Employment Insurance covers apprentices during full-time technical training, so apply before your school block starts since processing takes time.
School is the cheap part of this trade. SAIT's 2026/27 apprentice pricing (effective July 1, 2026) puts each 8-week period at $1,256 in tuition plus $357.50 in fees — about $1,614 per period, or about $6,454 across all four periods, before books and modules (roughly $600 per period — SAIT warns not to buy them ahead of time in case they are outdated). You earn a wage between blocks. The funding picture is straightforward:
With the hours, school blocks, and period theory exams done, you write the interprovincial (Red Seal) exam in the final period. SAIT states the passing mark is 70%. Passing earns the Alberta journeyperson certificate for the trade, and it carries the Red Seal endorsement: the national stamp that lets you work the trade anywhere in Canada without re-certifying. And per SAIT's program page, graduates also earn Gasfitter – Class B — the same double-ticket logic as Alberta's plumber apprenticeship, and the credential Alberta institutional employers (hospitals, universities, plants) routinely list next to the refrigeration ticket.
The money side: ALIS puts Alberta heating, refrigeration and air conditioning mechanics at an overall average of $41.35/hr with a $43.00 median, a $35.50 starting median, and a $48.50 top median. Those blends include apprentices, so licensed journeymen sit in the upper half. This is the highest median among the mechanical trades in the ALIS survey — the payback for the higher entrance bar.
The credential at the end of this apprenticeship carries more than the journeyperson certificate. SAIT states that on successfully completing the required working hours and technical training periods, graduates are awarded an advanced diploma in addition to journeyperson status by Alberta's Apprenticeship and Industry Training — alongside the Gasfitter B and Refrigeration and Air Conditioning Mechanic Red Seal already covered above.
That diploma also opens degree-transfer routes, if you later want management or engineering-technology study. SAIT lists 60 transfer credits toward the third year of NAIT's Bachelor of Business Administration for qualified tradespeople with Red Seal certification and three to five years of management experience who are eligible to apply (plus the high-school prerequisites), and transfer into Thompson Rivers University's Bachelor of Technology (57 credits) and Bachelor of Technology: Trades and Technology Leadership (60 credits), provided you meet all other admission criteria and space remains available. Check the receiving institution's current admission criteria before planning around a transfer — agreements and credit counts change.
One cost the guide's fee table does not itemise: SAIT notes this program requires personal protective equipment (PPE), which may be an additional cost on top of the roughly $600 per period for books or modules.

About four years. Alberta's Refrigeration and Air Conditioning Mechanic program runs four periods; each period is 1,560 hours of on-the-job work experience plus 8 weeks of classroom instruction and a theory exam, and each period is designed to take roughly a year. AIT allows up to 18 months between each requirement, so a layoff or a slow season does not automatically reset your clock — but the hours and school for each period must all be complete before you advance.
Yes. SAIT's program page states certification is required to work in this trade — you must be a registered apprentice working under a certified journeyperson or a certified journeyperson yourself — and the ALIS occupational profile cites Alberta's Skilled Trades and Apprenticeship Education Act: you must hold a certificate recognized by Apprenticeship and Industry Training (AIT) or be a registered apprentice to install, maintain, repair, or overhaul refrigeration or air conditioning systems in Alberta. Job Bank's national profile (NOC 72402) also lists Alberta among the provinces where trade certification is compulsory. Hours worked before your apprenticeship agreement is signed do not count, so register first.
AIT sets a higher bar for this trade than for most others: English 30-2, Math 30-3, and Physics 20 or Chemistry 20 — or a pass mark in all five Canadian General Educational Development (GED) or Canadian Adult Education Credential (CAEC) tests, or a pass on the AIT entrance exam. SAIT's recommended requirements add related career and technology studies (CTS) courses. You must also be a resident of or primarily work in Alberta, and hold citizenship, permanent residency, refugee status, a valid CUAET visa, or a post-graduation work permit. The physics requirement is real: refrigerant cycle work runs on enthalpy, gas laws, and electrical theory from period 1.
SAIT's program breakdown: Period 1 covers occupational skills plus an introduction to refrigeration, air conditioning and heating, electrical theory, and controls. Period 2 goes to basic refrigeration and air conditioning, basic heating, basic electrical theory, and basic controls. Period 3 is intermediate refrigeration and air conditioning, intermediate heating theory, intermediate electrical theory, and air handling theory. Period 4 is advanced refrigeration theory, advanced heating theory, complex air system theory, and advanced control systems. You must pass each section of the course (no less than 50% in each course, at least a 65% average overall) plus the AIT theory exam each period to advance.
Per SAIT's program page: 'Graduates will get Gasfitter B and Refrigeration and Air Conditioning Mechanic Red Seal.' The curriculum includes gasfitting fundamentals and gas-fired equipment troubleshooting, and Alberta employers routinely post for refrigeration journeypersons with the Class B ticket in hand — Mount Royal University's own journeyperson postings list the Refrigeration and Air Conditioning Mechanic journeyperson certificate or Red Seal alongside the Gasfitter – Class B certificate. It is the same double-ticket logic as Alberta's plumber program: one apprenticeship, a second credential that widens the work you can sign off.
The Government of Alberta's ALIS wage survey (the province's own occupational data) puts heating, refrigeration and air conditioning mechanics in Alberta at an overall average of $41.35 per hour with a $43.00 median — the highest median among the trades covered here. Starting-level workers show a $35.50 median, and top-end workers a $48.50 median. Those figures blend apprentices with journeymen, so licensed journeymen sit in the upper half; late-stage apprentices typically earn well into the $30s. Alberta's median also tops the national spread for NOC 72402, which is part of why the trade draws workers from other provinces.
The 8-week technical training blocks are offered at SAIT in Calgary and NAIT in Edmonton — the AIT-recognized providers for this trade. SAIT's 2026/27 apprentice pricing (effective July 1, 2026) puts an 8-week period at $1,256 in tuition plus $357.50 in fees — about $1,614 per period, or about $6,454 across all four periods, before the roughly $600 per period of books and modules. You earn a wage between blocks, the Canada Apprentice Loan covers up to $4,000 per period of technical training interest-free, and Employment Insurance covers apprentices during full-time school blocks.
AIT apprentices may take the interprovincial (Red Seal) exam in the final period of training. SAIT states the passing mark on the interprovincial qualification exam is 70% — the same 70% as each provincial period exam. Passing earns the Alberta journeyperson certificate with the Red Seal endorsement: the national stamp that lets you work the trade anywhere in Canada without re-certifying. Our Red Seal guide explains the endorsement mechanics and the trade-qualifier route for experienced workers.
Two routes. SAIT offers a pre-employment Refrigeration and Air Conditioning program that prepares you to enter an apprenticeship with hands-on skills; completing it qualifies you to challenge the first-year apprenticeship exam. NAIT's one-year HVACR Technician certificate goes further: graduates receive recognition for periods 1 and 2 of technical training toward the Refrigeration and Air Conditioning Mechanic apprenticeship, with full credit awarded once you successfully challenge the period 1 and 2 technical exams and complete the required on-the-job hours. Neither route replaces the employer — you still need a sponsoring employer to log the 1,560 hours per period.
