Heating, ventilation, and air conditioning
Societies

Many HVAC engineers are members of the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE). ASHRAE regularly organizes two annual technical committees and publishes recognized standards for HVAC design, which are updated every four years.

Another popular society is AHRI, which provides regular information on new refrigeration technology, and publishes relevant standards and codes.
