Not ‘Business-as-Usual’

  • Some of the practices, techniques and procedures, as well as the information, tools and equipment which have been commonly used in mobile air conditioning system diagnosis and service will be different for mobile air conditioning systems using R744, HFC-152a and HFO-1234yf. Modifications and adjustments will have to be made based on the individual characteristics of each refrigerant.

  • Technician training and certification is required to ensure safe, efficient and effective service and repair of mobile air conditioning systems using R744, HFC-152a and HFO-1234yf.

  • The technician must be trained to recognize which refrigerant is being handled, be trained to handle it safely and be equipped with the essential information, proper equipment and tools, which may be unique to a single refrigerant.
