In the Understanding and Diagnosing A/C class, you’ll go beyond minimum requirements for recovery, evacuating, recharging, and recycling by offering real world examples in diagnosing and repairing A/C electrical, computer / BCMs, climate control and electronic components. Most of today’s vehicles come equipped with electronically controlled A/C systems.
In the last 120 years, automotive passenger heating has evolved dramatically from open carriage-type automobiles with little occupant protection from the elements to complex electric vehicle (EV) heating, ventilation, and air conditioning (HVAC) systems.

A large percentage of MACS members have refrigerant identifiers and use of them on vehicles that come into their shop for A/C service prior to beginning any service work is standard procedure.
However, there are a lot of non-MACS member shops who do not have identifiers and unfortunately are not aware of the potential issues which can be caused by refrigerant contamination.
As mentioned in last week’s article, the first thing I did with the machine was check the pressure of the refrigerant in the tank. It was extremely high (well over 400 PSI) indicating there was a refrigerant contamination problem.
MACS is changing leadership. Elvis L. Hoffpauir, is stepping down at the end of January 2022 from his duties as MACS president and chief operating officer to enjoy retirement. Following a 42-year distinguished career at the Mobile Air Climate Systems Association (MACS), Elvis will transition to past president and association advisor.
To help service shop owners, MACS has created a 30-page consumer guide for your customers that explains how their car’s engine cooling system and air conditioning system works. “Getting to know your car’s air conditioning and engine cooling system,” details how these vital climate systems work and why they may require an extensive repair.
Modern heavy-duty equipment is basically comprised of computers with operating units attached. In short, it is a multiplexing system that replaces traditional power distribution devices with ECUs that communicate electronically over the vehicle datalink.
MACS is working on a project, to collect A/C charge information for Tesla vehicles, and we need your help!
Most condensers have different fittings on the inlet and outlet. The locations of the inlet and outlet on most condensers will not allow lines to be connected incorrectly, even if the fittings do happen to be the same size. Lastly, the designs of the mounts on most condensers prevent a unit from being installed upside down. However, none of these characteristics apply to the condenser the technician had installed.
