When your car or truck has an air conditioning problem and needs service, what should you do? If your A/C system only needs some refrigerant, you can probably recharge the a/c system yourself. But if you are having cooling problems, leaks or electronic control problems, you should probably seek out a repair facility that specializes in air conditioning service work.
Our advice is to seek out a repair facility that is a member of MACS, the Mobile Air Conditioning Society. MACS is a non-profit trade association for repair shops that do air conditioning service work. MACS promotes training, education, professionalism, and most importantly "Best Practices" for servicing and repairing your vehicle's air conditioning system.
Since 1991, MACS has assisted more than one million technicians to comply with 1990 Clean Air Act requirements for certification in refrigerant recovery and recycling to protect the environment.
Recently, the Climate Protection Partnership division of the U.S. EPA teamed up with MACS to publish and promote six mobile air conditioning best service practices checklists. These checklists are written for professional technicians to help them environmentally safe and technically proper air conditioning service and repairs. The purpose of the checklists is make sure your vehicle is serviced correctly when you take it in for air conditioning service work.
If your shop is NOT following these practices, you should bring it to their attention - or take your vehicle to another shop who does follow the Best Practices recommendations.
Note: The Best Practices checklists are voluntary recommendations, and are not required by law. Even so, they do reflect current thinking on the best ways to properly service and repair automotive mobile A/C systems. The input for these checklists was provided by highly experienced A/C technicians who are familiar with the right ways and wrong ways of servicing service A/C systems.
The checklists for Best Practices include:
A/C Service (general)
Field Repair and Assembly of A/C Hoses
A/C Equipment Maintenance.
These checklists can be downloaded free of charge in pdf file format from the Climate Protection Pledge section of the MACS Worldwide website at this link:
