€‹heating, ventilation, air conditioning, and refrigeration draughter
HVACR drafting specialist
HVAC drafters typically work in office settings, using computers and other technical equipment for the majority of their workday. They may occasionally need to visit construction sites or manufacturing facilities to gather information and make observations about the HVAC systems they are designing.
To become a heating, ventilation, air conditioning (and refrigeration) drafter, you typically need an associate degree or certificate in drafting or a related field, as well as experience using CAD software and other technical tools. Some employers may prefer candidates with a bachelor’s degree in mechanical engineering or a related field. HVAC drafters must have excellent attention to detail, strong communication skills, and the ability to work well in a team environment.
ISCO skill level
ISCO skill level is defined as a function of the complexity and range of tasks and duties to be performed in an occupation. It is measured on a scale from 1 to 4, with 1 the lowest level and 4 the highest, by considering:
- the nature of the work performed in an occupation in relation to the characteristic tasks and duties
- the level of formal education required for competent performance of the tasks and duties involved and
- the amount of informal on-the-job training and/or previous experience in a related occupation required for competent performance of these tasks and duties.
Heating, ventilation, air conditioning (and refrigeration) drafter is a Skill level 3 occupation.
