Typically, an HVAC service technician learns the craft by attending a secondary or post-secondary technical school. Some commercial organizations or private employers offer an alternative to formal education by offering apprenticeship skills in the field. A thorough education is an advantage, as the job often requires project tracking and proper handling of natural gas, oil, electricity, and solid fuel. Many areas require technicians to meet licensing requirements, which may involve classes and an HVAC certification exam. These licenses can provide customers with peace of mind that the technician is following security protocols and meeting regulatory compliance standards for new installations.
