Tech Tips:

How to Use a Manufacturer Fan Table and Why They are Important

Many installers and service technicians know how to read and use a manufacturer fan table, but this is a quick review with a few extra tips for newer techs. It’s also a good reminder to senior technicians about how this easy-to-use practice can also be easily abused. At installation, properly setting up airflow is imperative to the […]

Powered Attic Ventilation

When I first started in the trade, I used to advise customers with hot attics to install powered attic ventilators (PAVs) to “suck” that hot air out of the attic. It just made sense to me at the time; if the attic is hot, get the hot out! When I started learning more about design, […]

HVAC School – For Techs, By Techs

Real training for HVAC ( Heating, Ventilation, Air Conditioning and Refrigeration) Technicians. Including recorded tech training, interviews, diagnostics and general conversations about the trade.

In this business and building-oriented short podcast episode, Bryan discusses the limitations and downsides of intentionality. He also talks about the differences between people who act, think, and work quickly and those who are a bit slower, more detailed, and more methodical; there are upsides and downsides to both.

People often talk about being intentional, but those intentions have little impact on the world unless they lead to action. Intentionality feels productive, but it doesn’t make a difference unless the execution piece is also there. Likewise, skills come from action, not aspiration. Books and podcasts are tools that support efforts to improve, but you can’t improve skills without practicing.

There is also the career paradox: we expect people, especially kids, to know what they want to do when they grow up. Their answers aren’t backed by any real-life experience. People do the same as adults; we expect them to know what they truly want to do when they haven’t necessarily been challenged (or physically made something real or fixed something with their hands). In many of these cases, opportunism and trying new things out, even if it means messing up or being criticized, are more important than intentionality.

It helps to think of opportunism in terms of “hat” decisions, “hairstyle” decisions, and “tattoo” decisions. “Hat” decisions are things you can try out without consequences; be opportunistic. “Hairstyle” decisions have longer-lasting effects and require a bit more intentionality, but it’s still good to make some of these decisions. “Tattoo” decisions have lasting effects and require intentionality.

Intentionality is most useful when we have the experience already; act first and reflect later.
