Just do it the right way

By Elvis L. Hoffpauir, MACS president and COO

However tempting it may be to skip a step here and there to speed up a service job in this busy summer season, don’t do it!

Ever since this industry entered the era of multiple automotive A/C refrigerants (some legal, some illegal), due caution and good sense have dictated using refrigerant identification equipment on every vehicle brought into the service bay.

Shops now collecting service data for the 2013 MACS Field Service Survey* have proven the wisdom of using refrigerant identification technology once again.

Early in the data collection phase, shops are discovering contaminated systems. One example is a 1985 (R-12 vintage) vehicle. The service complaint ultimately proved to be a restricted liquid line, but the shop technician’s first step, fortunately, was to use the refrigerant identifier.

The system contained some R-12 (25.5%) and a little bit of R-134a (2.4%), but the primary refrigerant constituent was hydrocarbon, registered at a whopping 72.1%.

In addition to guarding against what a DIY consumer or unprofessional service provider might introduce into an A/C system, shops should also test each cylinder of refrigerant purchased. Here the first line of defense is to buy quality product through a supplier you trust, but even this precaution provides no guarantee.

Refrigerant counterfeiting is big business, and counterfeiters have grown more and more sophisticated.

Protect your service equipment, your refrigerant supply and your reputation. Use your refrigerant identifier on every vehicle you service and every cylinder of refrigerant purchased.

When having your mobile A/C system professionally serviced, insist on proper repair procedures and quality replacement parts. Insist on recovery and recycling so that refrigerant can be reused and not released into the atmosphere.
