Being up-to-date can mean different things. In the case of the HVACR technician who has a great deal of general training along with extensive work experience in troubleshooting refrigeration and air-conditioning systems, up-to-date can mean a short, one-hour, factory-provided training session on the latest version of  ECM (Electronically Commutated Motor) and the newest, updated troubleshooting procedures that don’t apply to earlier versions of this type of motor but do, in fact, apply only to this newest product.

And, without that “up-to-date”, one-hour information session, that technician may be lost when encountering that particular motor, which could result in wasted time, a mis-diagnosis, unnecessary expense for the customer, stress for the technician, etc….

“Up-to-date” can also have a different meaning for somebody without the great deal of training along with extensive work experience as described above. It could mean that this particular technician needs either an overview or a review of the fundamental concpets of electrical troubleshooting, or the general test procedures related to a particular type of relay or control system, or, maybe the same level of information related to refrigeration and air flow systems.

And, that “up-to-date” information could have been published this year, last year, the year before that, yet another year before that, or even five years ago, and it it will be “up-to-date” because the fundamental concepts being taught were developed and understood early in the history of  the development of HVACR (such as the physics that govern the ability of a refrigeration system to accmplish heat transfer or the concepts that explain how to trace an electrical circuit from source-to-source in order to isolate that circuit and then perform the appropriate component testing….providing one has an understanding of what ‘right is in the first place’….to determine through the process of systematic elimination whether that component or another one in the circuit is responsible for the failure of the equipment to operate), because it’s general, common-sense information that technicians need to know in order to do their job.

All of this simply means that technicians need to know if what they need is ‘up-to-date” specific, applying-only-to-a-particular-component information, or ‘up-to-date’ information on general principles that actually helps them do two things:

1. Develop their overall troubleshooting skills.

2. Be able to completely understand what’s being presented in the first ‘up-to-date session  I mentioned at the beginning of this post.

Learn from yesterday….Live for today….Look forward to tomorrow
