Leader Led Training

MACS instructors are available to come to your facility to teach courses on professional mobile A/C service and repair and other automotive systems. MACS can customize classes to fit your specific requirements, combining elements from all of our mobile A/C courses to create courses specific to your organization’s training needs. MACS also has a state-of-the-art training facility at MACS headquarters in Lansdale, PA. should you wish to bring your employees to us as an option. 

 MACS can also teach classes at your facility remotely via webinar. A webinar means your techs watch the presentation on a special website on the internet and listen and communicate with the instructor by telephone.

All costs are dependent on location, number of students attending and hours of instruction. For more information on MACS training in your facility email macsworldwide@macsw.org or call the MACS office at (215) 631-7020 x 0.


Mobile A/C Training Classes

Refrigerant Recovery and Recycling Certification (Section 609)

All technicians opening the refrigeration circuit in automotive air conditioning systems must be certified in refrigerant recycling and recovery procedures to be in compliance with Section 609 of the Clean Air Act Amendments of 1990. The MACS onsite training and certification program consists of an audio-visual presentation of EPA approved recovery and recycling procedures, distribution of the MACS certification training manual followed by a 25-question, closed book test. Can also be taught via webinar. Certification for CFC-12, R-134a and R-1234yf refrigerants.

MACS also has an online recorded Section 609 test prep webinar available for purchase at $25. in the MACS web store. This video is free for MACS Members in the MACS member-only section of our website. Click here to learn more.

Best Practices: Automotive Air Conditioning System Theory, Diagnosis, and Service Procedures

This course describes “Best Practices” service and repair methods pertaining to mobile A/C systems. When adhered to, the procedures outlined in this program should help assure more accurate diagnoses, high-quality long lasting repairs, reduction of comebacks and increased customer satisfaction. Its “Boot Camp” style approach delivers “everything you need/nothing you don’t” in a fast-paced, highly informative manner. Major subjects the course covers include:

A/C Systems: What They Do and How They Do It
A/C System Components: Description and Operation
A/C System Refrigerants and Oils
Essential A/C System Service Practices and Precautions
Mobile A/C System Temperature Testing

In this class, attendees will learn how to use temperature readings taken at various locations throughout an A/C system, to pinpoint problems. This in-depth program was developed by placing “bugs” in systems (both orifice tube and expansion valve) that simulate often-encountered real world situations. All “normal/good” and “abnormal/bugged” conditions were photographically documented. The “results” of the bugs, when matched up with the temperature readings taken, show how things like under/over charge, internal restrictions, blocked cabin air filters and condensers, and other improper conditions, affect A/C system performance and operation. Armed with the knowledge from this program, when confronted with similar circumstances in the field, technicians will have a good understanding concerning how to proceed with authoritative diagnosis and effective repair.

Electrical Functions in Air Conditioning

The electrical functions program covers the fundamentals of electricity as applied in automotive systems. Specific air conditioning electrical components are discussed in detail. Also covered are test instruments, electrical circuit operations and schematics, operation of A/C electrical components and battery/charging system testing. Completion of this program will prepare automotive technicians to approach some of the more difficult electrical challenges. Much of the material in this course is directly applicable to other electrically-operated vehicle systems.

Maximizing Your A/C Tools and Equipment

What’s the right tool for the job? This course delivers an in-depth hands-on look at how to select and use the right tool for the job during a mobile A/C repair. Tools covered include; refrigerant identifiers, electronic leak detectors, ultraviolet dye type leak detection systems, CFC-12 recovery/recycling machines, HFC-134a and R-1234yf recovery/recycling machines, manifold gauges, vacuum pumps, refrigerant weighing scales and/or charging cylinders, various temperature measuring devices, such as dial thermometers, digital pyrometers, infrared thermometers, etc., digital multi-meters, scan tools, hose repair crimping tools, spring lock coupling disassembly and service tools, A/C service fitting service tools, orifice tube service tools, cooling system pressure testers, cooling system flush and recycling equipment, compressor clutch service tools, hand held vacuum pumps, battery/charging system testers, charging/service hose sets, coolant refractometers, heat guns, and recovery only machines. Shop must provide the equipment.

MACS Mobile A/C Update 2020

Every year the Mobile Air Conditioning Society creates a special mobile A/C update clinic to help working technicians keep up with the rapidly changing mobile A/C service and repair industry. MACS manager of technician training, Steve Schaeber wants today’s technicians to, “Spend a few hours investing in mobile A/C and engine cooling training that they can take home to their shops and put to work the next day to keep them efficient and profitable while offering customers reliable repairs.”

To achieve that goal, the training topics for MACS 2020 Mobile A/C Update clinics are:

  • Sometimes we think too hard
  • Manifold gauge pressures vs. line temperatures: The inexact science evolves
  • Fluorescent leak detection
  • A/C airflow switches to defrost
  • A/C performance in hot climates / engine temps
  • Software fix for HVAC Noise?
  • In-car and OAT (Ambient) temperature sensors
  • Electronics comes to the “thermostatic” expansion valve
  • A few A/C shorts
  • Update on refrigerant regulations, R-1234yf and Section 609 Certification
