HVAC is an industry, not a license.
There are many different licenses people in the HVAC industry can hold. This includes:
License | Authority | ||
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.
