The Mobile Air Conditioning Society (MACS) Worldwide has announced the availability of six mobile air conditioning best service practices checklists to help the automotive service professional provide environmentally and technically proper mobile A/C system service and repairs. The checklists were created in partnership with the Climate Protection Partnership division of the U.S. EPA. While A/C service rules can differ depending on the jurisdiction a shop is doing business in, a quick scan of the checklists reveal that they focus on the proper procedures that should be common across the industry. These checklists cover Best Practices for A/C Service, Leak Detection, Refrigerant Recovery, System Charging, Field Repair and Assembly of A/C Hoses and A/C Equipment Maintenance. They are designed to promote efficiency and curb waste of resources. The checklists are useful for training new technicians, helping to incorporate efficient practices in the shop culture, and can be posted as tangible reminders and logs for often overlooked but critical functions like tool and equipment maintenance and care. These checklists can be downloaded free of charge in pdf file format from the Climate Protection Pledge section of the MACS Worldwide website.
