The "Do No Harm" ethic of the professional handyman

 Many people have heard the phrase, "Do no harm," especially in relation to physicians.   But the professional handyman also keeps that ideal close to the chest as we go about our work as well.

Many of us find ourselves doing maintenance work and tasks related to other fields such as plumbing,  HVAC, and electrical systems.  While we ourselves are usually NOT a licensed professional of those fields, we often perform inspection and maintenance tasks of those kinds of systems and devices. 

So, we often are quite familiarized with at least the general concepts and basics of those fields so that while we perform the few tasks we are able to do related to them, we also don't break them or make them worse.  Do no harm.

Water heater draining, furnace filter changing, checking or changing light bulbs, switches, and receptacles, cleaning AC units.  These and many other tasks are projects the professional handyman find ourselves doing frequently.   It's in our own and our customers best interests to have a good understanding of at least the basics of these systems so as to do them correctly.

In fact, many handyman and maintenance training programs in community colleges and other such legitimate training programs require classroom education on at least the "101" level knowledge of these areas in order to graduate or obtain certification. 

Like I said, the point is to Do No Harm.  We want to maintain optimum functioning,  identify issues, and at the very least, don't make things worse.
