HVAC is an industry, not a license.
There are many different licenses people in the HVAC industry can hold. This includes:
|H||Heating||Gas Technician or Oil Burner||Technical Standards and Safety Authority (TSSA)|
|V||Ventilation||Sheet Metal Mechanic||Skilled Trades Ontario (STO)|
|AC||Air Conditioning||Residential AC Systems Mechanic 313D||Skilled Trades Ontario (STO)|
|R||Refrigeration||Refrigeration and AC Systems Mechanic 313A||Skilled Trades Ontario (STO)|
|Other||Plumber and Electrician||Skilled Trades Ontario (STO)|
All licenses regulated by Skilled Trades Ontario (STO) require a 3 – 5 year apprenticeship. However, the Heating licenses regulated by TSSA are not apprenticeships. You can complete an approved course, pass your TSSA exams with a minimum of 75% and be fully licensed.
