A/C Advanced diagnostic techniques
One bright star among a galaxy of premiere experts and trainers making up the MACS 2017 faculty is Peter Orlando of Automotive Training Technologies. He explains that “achieving the desired result of a successful repair, a satisfied customer, and a fair profit on your work is a process,” and he cautions “never stop diagnosing until you have nothing left to diagnose!” His class will cover customer/operator vehicle problem interrogation; trouble-shooting main and sub electrical system malfunctions; scan tool data interpretation versus actual A/C performance issues; A/C actuator testing using low amp current probe; and cause and effect of climate control pattern failures.

Optimizing system charge levels
Peter McArdle of Four Seasons notes that “Condenser technology has evolved dramatically over the past 20 years. We are accomplishing the same job today with only half the refrigerant charge of just two decades ago. Your replacement condenser may be more efficient than the one you are replacing. However, its internal physical volume may be significantly different than the OE unit. Even a replacement OE dealer condenser may not be an exact match for the original. Please join me for this class and learn how to optimize the system charge level to match the replacement condenser.”

Telematics and advanced body electronics
This course will take the intermediate to advanced automotive technician on a journey starting with F.R.E.D. (Frustrating Ridiculous Electronic Devices) used in today’s advanced body electronics systems such as Telematics, C.A.N. Expansion buses, M.O.S.T. Buses (optic and wired), Forward Cameras and Smart Key Systems. It then blasts him into future technologies, which are coming sooner than you think. Future technologies including autonomous cars, collision avoidance systems and off peak automatic software update will be covered. Case studies and electronic circuit diagnostics round out this fun and informative class by MACS contributing technical writer Dave Hobbs that will sharpen your diagnostics skills for the automotive electronics of today and tomorrow!

Climate control sensor and actuator diagnostics
“Climate control systems are evolving; are your diagnostic skills keeping up with the changes?” Bob Pattengale of Robert Bosch says, “the first step in solving any vehicle system issue is understanding the theory of operation and how the common components operate.” In his session, Bob will provide the information needed to develop a solid diagnostic approach.

Automotive HVAC systems: Essential diagnostics
This class provides a solid foundation of essential HVAC diagnostic procedures, based upon diagnostic best practices, in order to assure correct and complete diagnostic conclusions of common HVAC failures. Jim Cokonis, CARQUEST Technical Institute, will cover topics including temperature and pressure testing, the diagnosis of compressor clutch controls, PWM fan diagnostics, and variable displacement compressor controls. Special emphasis will include how to evaluate overall performance and efficient choice of diagnostic methods. The effects of internal heat exchangers and how they change expected test results compared to a “traditional” system will also be featured.

Diagnostic directions: Making the most of the first five minutes
Tim Iezzi of Iezzi’s Auto Service explains: “As we know, diagnostic tasks can be among the most challenging jobs we perform, but this work also represents some of the most important. Many shops find it difficult to charge for diagnostic work, and no one wants to spend five hours on something they may only be billing an hour for.  What I do in my class is break down the diagnostic process and work on developing methods that can be applied to most vehicles universally, including systems other than air conditioning.  I will also explain the methods that I personally use on every vehicle that comes in the shop for A/C to gather as much information as possible on the car as quickly as possible. I will then reinforce this through case studies including one highlighting what can happen and how much time can be wasted when you don’t have a process or a direction.”

THURSDAY ALL DAY
HD TRUCK / OFF-ROAD VEHICLE TRAINING
Is a refrigerant change coming for HD vehicles?
Gary Hansen of Red Dot notes, “With millions of automobiles and light trucks using R-1234yf, what’s the outlook for the heavy duty truck and off highway marketplace? Is R-1234yf just around the corner? What are the challenges in changing refrigerants? What are the potential design and economic impacts that need to be considered? Could there be other alternatives? Come find out the latest answers and solutions.”

Caterpillar HVAC system design and service
This session will include the latest updates and repair procedures for servicing Caterpillar HVAC systems, followed by a summary of some of the most up to date designs just now entering production. The focus of this part of the discussion will be the unique features of these new designs with an emphasis on the impact on field diagnosis and repair. Additionally, the session will include a discussion of the evolution of electrical control systems used on CAT machines.

HD HVAC electrical/electronic diagnosis
Fred Johnson of Dyson International prefaces his course content with the following thoughts: “Diagnosing today’s heavy-duty vehicle HVAC electrical and electronic systems is complicated by different factors. Many technicians are still frustrated diagnosing vehicle electrical problems, while the development of complex HVAC electronic systems progresses at uncontrollable speed, outpacing the skill level of many technicians. So what creates a great electrical technician? Good training, up-to-date service information, schematics, understanding how to properly use a multi-meter, and practice, practice, practice. What creates a great electronic technician? Good training, up-to-date service information, proper scan tools/diagnostic software and finally, most important, reading and comprehension skills. Reading and comprehension abilities are fundamental skills necessary for technicians to understand the interaction of complex heavy-duty vehicle HVAC electronic systems. Today’s shop owners / managers / technicians fight a daily battle to keep heavy-duty vehicle diagnostic and service procedures up-to-date.”

Bus A/C: Covering all he bases
This session with Jeff Holbert of Trans / Air will focus on the differences between automotive and bus air conditioning, and why bus A/C diagnosis can take longer. Included: A look at some case studies showing how a simple repair took longer because of overthinking the problem.

 Solving the HD ‘no cooling’ crime
Dick Ennis of T / CCI Manufacturing explains his approach to this training as follows: “In a nutshell, the intent of the presentation is to change the ‘old school’ paradigm of service methods that tend to forego asking questions and collecting clues. To accept the customer stating ‘My AC doesn’t work,’ and responding, ‘I’ll check it out and give you a call’ often leads to excessive diagnostic time, which impacts the bottom line. The addendum of the ‘case studies’ should prove interesting, as well, given the unique circumstances when failures occurred but did not have easily determined root cause.”

 HD HVAC and Kenworth today
“Mobile AC has never been more demanding of service technicians than it is today,” says trainer Keith Johnson. “Demands on technicians ranging from legislative mandates, access to service information, and cutting-edge technology advances are an everyday challenge for technicians and business owners. The MACS presentations featured at its annual convention are geared to address those needs and help all stakeholders achieve customer satisfaction. I hope that the addition of Kenworth system and service information adds clarity and assistance to the service industry.”

 

SATURDAY MORNING AND AFTERNOON
PASSENGER CAR / LIGHT TRUCK TRAINING
New model presentation for 2017 Prius Prime
Bruce Biven of Lexus will offer a presentation on a new type of system. He notes that “the 2017 Prius Prime is a plug-in hybrid vehicle with a heat pump climate control system. The climate control system is totally new and very different from a conventional climate control system. The system is capable of producing heat without starting the engine at temperatures as low as 14° F.  The system can operate in six different modes. System components include: internal and external condensers, two electronic expansion valves, a cyclone separator valve, a gas injection electric compressor, two magnetic flow control valves, and five temperature sensors.”

Four horsemen of electrical circuits
Tony Martin of Automotive Curriculum Consulting explains that “even experienced technicians can benefit from a review of basic electrical theory. All electrical concerns boil down to simple failures, no matter how complex the system.  The “Four Horsemen of Electrical Circuits” will add solving electrical problems, including visual inspection and practical diagnostic strategies to your personal toolkit .”

Changing role of refrigerant systems within today’s powertrains
Presenter Lindsey Leitzel of MAHLE / Behr Troy, Inc. describes this session as follows: “The story of vapor compression refrigerant systems usage in vehicles is being rewritten. These systems can’t just be called air conditioning systems any more. In this session, we’ll review how the refrigerant system is being adapted to address the thermal needs of today’s vehicles.”

Diagnosing today’s refrigerant system concerns
Jerry Mungle of ACDelco will discuss today’s service arena, noting that “modern automotive HVAC systems have undergone some dramatic changes in recent years. We are on the threshold of an advanced era of refrigerants that bring new tools and service procedures. Often, failure of a refrigeration system can be traced to problems other than component malfunctions. This session will cover common service concerns on today’s vehicle refrigeration systems, and will include vehicles with both R-134a and R-1234yf. Topics will include common failures, strategies for proper diagnosis and common repair techniques.”

We can’t do it like we used to!
This session with Gates Corp.’s Robert Bassett will explore root-cause failures along with the effects they have on the coolant system. You will learn: about the latest inspection recommendation process called I60R90 / Be System Smart; how contaminated coolant drives coolant system failures; why industry research says, failure rates can be as high as 40% for the radiator and 95% for the water pump after replacement if a flush was not part of the repair process; why “if” certain conditions prevail in the coolant system, failure can be imminent; two distinct failure modes for the water pump and how to eliminate them during the repair process; how aging thermostats create erratic temperature cycling for the radiator; and why your customer may return with additional failures in less than seven months / 7,700 miles if the coolant system was not flushed during the repair.

2017 FCA R-1234yf update
FCA’s Al McAvoy notes that “FCA is now in our fourth Model Year of producing R-1234yf vehicles, with over a million FCA vehicles currently on the road using R-1234yf. If they haven’t already, many of these vehicles will soon be making their way into your shops. Be sure you’re prepared with the latest service techniques, tools and equipment required to properly service your customer’s vehicles. This seminar will cover the latest factory information on the operation, diagnosis and service of FCA’s R-1234yf equipped vehicles.”

SATURDAY ALL DAY
HD TRUCK / OFF-ROAD VEHICLE TRAINING
How to make custom A/C hose assemblies
Presenter Gene Dianetti of Parker Hannifin Corporation explains, “Many service shops make their own or attempt to repair A/C hose assemblies. It can be a challenge to do this correctly given the numerous options available in the industry. In the end, a part that could leak or fail shortly after installation is never a good outcome. There are many factors to consider when selecting hoses, fittings and seals that meet SAE or OEM quality and performance levels. My presentation will share some of these challenges and  show why it is important, mandatory, in fact, to select components to do such repairs that meet these requirements. I hope to see you there!”

AGCO Updates and refrigerant capacities
“Due to the many different designs of climate control systems, the heavy duty, off road equipment service technician faces numerous challenges,” says Sherwood Wheeler of AGCO. “One challenge is making the correct diagnosis the first time and avoiding unnecessary repairs. Using temperature can help the technician make a correct diagnosis, regardless of the design or manufacture. In my training session, we will cover the technique of using temperature to diagnose an A/C system and then look at ‘what do the numbers mean’ In addition, I will review the latest A/C design changes and provide updated refrigerant capacities for both current and legacy products manufactured and supported by AGCO Corporation.”

When is cold air not cool?
“Ward Atkinson has shared so many meaningful papers that it is easy not to get our arms around the applications of the documented test results as they apply to fleet vehicle management,” explains MACS trainer John Brunner. “A great example of this is live recorded testing that Ward delivers in a publication entitled ‘Show Me the Data.’  In my experience training and certifying fleet technicians, I have developed techniques and procedures using J2788 R/R/R equipment that have led to improved vehicle availability and a significant reduction in costly system failures. Ward helps us understand the pathology and cause of these severely elevated temperature failures that literally burn up the compressor. Unfortunately, the timing of this breakdown can come when the system is putting out colder duct air than normal. How cool is that?’

A/C valve application and installation
The A/C system has several access ports that are used to monitor and service the A/C system. These ports consist of a valve element inside a port, which is usually brazed to the A/C line. In this presentation, Jeff Schultz will discuss the A/C Valve Application & Installation Manual, including information about R-1234yf refrigeration valves, cores and service ports. Many different types of valves and seals will be compared, as well as core selection and system application.

Navistar Durastar and Prostar HVAC systems overview
Larry Turay of LETCO Enterprises notes that “the ongoing challenge for repair shops is the huge amount of information that is required to work on modern HVAC systems. My goal is to go through these vast resources and provide attendants with a quick reference of the most needed information to make the repair in a timely manner with the minimum risk of rework!”

FEATURED PRESENTATIONS
THURSDAY KEYNOTE LUNCHEON
The new role of an air conditioning system
How your future is changing to support hybrid, electric, fuel cell and other advanced technology vehicles.
Keynote speaker Dr. Mark Quarto, chief technical officer of Future Tech Auto, LLC explains, “No one could have predicted 20 years ago that the air conditioning system would play a major role in the core performance of a vehicle today. This is truly a revolutionary time for the air conditioning service business.”

FRIDAY MORNING KICK-OFF
GENERAL SESSION
The general session leading in to the opening of the MACS Trade Show will feature the annual Industry Update from MACS Technical Advisor Ward Atkinson. Special guests will include Chenise Farquharson, coordinator of the Significant New Alternatives Policy (SNAP) Program for the U.S. Environmental Protection Agency (EPA) and Tao Zhan, air resources engineer at California Air Resources Board. Farquharson and Zhan will update attendees on their agencies’ current and proposed regulations impacting the mobile air conditioning industry.
Atkinson says, “The mobile air conditioning industry is currently undergoing another major refrigerant transition. This includes new refrigerant component design changes and procedures to service the systems. Currently R-1234yf is the major refrigerant in the U.S. and European markets. Activity in the European market will include the introduction of R-744 carbon dioxide refrigerant systems.”
Tao Zhan notes, ““The California Air Resources Board is in the process of amending its regulation on small containers (small cans) of automotive refrigerant, in order to maximize the benefit to the consumers and the environment. Small cans are used by consumers and some professional technicians to recharge automotive air conditioners. The original regulation took effect in 2010.”
Chenise Farquharson comments, “Through the SNAP program, EPA continuously reviews and lists as acceptable substitutes that reduce overall risk to human health and the environment. I’m looking forward to sharing information on our latest actions, which include the listing of HFO-1234yf as acceptable, subject to use conditions, for certain vehicle types.”

NEW TO MACS IN 2017
Free marketing and advertising consultations offered on the trade show floor
MACS CEO Andy Fiffick comments, “Digital / social media advertising is now a necessity to compete for new clients in today’s business environment. Digital advertising results can be hard to track, the programs are varied and confusing, and costs can be excessive if you don’t know how to properly use and calculate your ROI for your digital program.  There are ways to take the guesswork out of tracking your results and effectively growing your client and car count. These one-on-one sessions are offered to introduce participants to effective approaches in the use of these new tools in a digital world.”

Rad Air got its start in 1975 as a three-bay radiator and A/C specialty shop. Rad Air now has 12 locations, 84 service bays and 56 technicians.
Panelists will include Jim Atkinson of Car Repair Company, Caroline Acebedo of Marks Air, Melanie Gann of Four Seasons, Brittany Gumucio of Rad Air Complete Car Care and Christian Klein of RPM Auto Marketing.

ENTRENAMIENTO DE A/C PRESENTADO EN ESPAÑOL
Trainer Leo Salinas:
El aire acondicionado automovilístico que conocemos hoy en día es muy diferente a lo que fue años atrás. Por ejemplo en los años 70’s y 80’s el aire acondicionado era tan simple que muchos dueños de autos intentaban reparar por ellos mismo el aire y en muchos casos funcionaba.
Hoy en día, el sistema de aire acondicionado de autos ha cambiado drásticamente y requiere mecánicos calificados para diagnosticar el sistema, independientemente de su fallo. Utilizar unos manómetros y una máquina de hacer vacío no necesariamente será todo lo que necesites para reparar el sistema. Para reparar correctamente un aire acondicionado moderno necesitaras horas de entrenamiento y experiencia reparando.
Los componentes en el sistema han cambiado, el compresor ahora está controlado por computadoras y sensores. Las capacidades de refrigerante y aceite se han reducido y a la misma vez tenemos un cambio de refrigerante.
En esta presentación se discutirán componentes del auto, porque estos fallan y  porque debemos remplazarlos. Tendremos estudios de casos que demostraran el proceso de reparar problemas comunes que puedas encontrar diario. Esta información es buena para los principiantes o los técnicos ya experimentados.

Trainer Agnes Perez:
En Estados Unidos (USA) existe el “Clean Air Act Amendments” la misma vela por que los técnicos de refrigeración para que realicen las medidas necesarias en el manejo de los refrigerantes. Esto es importante para poder estar en acuerdo con las reglamentaciones federales, por eso es necesario certificarse bajo la Sección 609 que maneja el refrigerante R12, R134, y R1234YF.
Durante la convención se estará ofreciendo esta certificación en español para todos los interesados en tomar el examen. El examen consiste en una presentación y donde luego tomaran el examen de 25 preguntas a libro cerrado. Sera un proceso sencillo que podrán aprovechar dentro de la Convención.

Preguntas Comunes
1.    ¿Quiénes deben tomar el examen?
a.  Toda persona que no tenga la certificación
2.    ¿Tengo la certificación debo tomar este otra vez?
a.  Si ya tienes la certificación no es necesario que tomes el examen. Ahora si te interesa que diga R1234YF entonces si deberás tomarlo
