What Is HVAC?
Heating, Ventilation, Air Conditioning (HVAC) are trades and an industry that are constantly changing. Products, skills, trade tools, knowledge, and trade license requirements are always getting updated for people working in the HVAC industry.
Gas technicians in Ontario fall under different categories and are registered with TSSA. Gas technicians have different categories and limitations as well. A G2 Gas Technician is limited up to 400,000 BTU in gas input equipment, whereas a G1 Gas technician is unlimited. A G1 Gas Technician will have far more experience, education, training and knowledge then a G2 Gas Technician.
Residential Air Conditioning (313D)
313D mechanics are licensed in Ontario and are limited to size and type of equipment they can work on. A Refrigeration and Air-Conditioning Systems Mechanic (313D) is restricted to working on systems that are installed as independent units in dwellings, use a maximum of 240 volts/60 amps and for which the cooling capacity does not exceed 60,000 BTU (5 tons).
Refrigeration Mechanics (313A)
Refrigeration mechanics are licensed in Ontario and generally work on anything that an air conditioning mechanic can work on but no limits to size and type. 313A mechanics can work on any residential, commercial or industrial equipment within their skill set and knowledge. Then there are specialized mechanics that work on equipment and systems like ammonia, chillers, cooling towers that air conditioning mechanics cannot work on due to license limitations.
Licensed and certified tradespersons are the best resources for knowledge of the equipment they service and install. Most mechanics share, learn, and grow in skills together with other tradespeople and equipment manufacture training.
