Oxy-Acetylene Torch Tips and BTUs

Oxy-acetylene torch tip manufacturers publish charts that tell us the ideal applications for each tip size, which is quite useful on its own. After all, a small tip may be great for a ⅜” liquid line but would hardly make a dent in 2” commercial refrigeration piping. But we can also take the information from […]

Compressor Mass Flow – Some Thought Experiments

In order to wrap my head around diagnostic issues, it helps me engage in thought experiments where I think of more extreme examples of an issue or situation or consider the ideal to find the “edges” of a concept. Once I find the extreme edges, I can begin to sort down to a more exact […]

Using the Socratic Method to Meet Trainees Where They’re At

We’ve all probably been in this situation before (maybe in both people’s shoes at different points of our careers): A technician is on the job with their apprentice. The technician tells the apprentice where the probes go on the service ports and exactly what the superheat and subcooling are. The apprentice’s eyes glaze over, and […]

Making of a TV Show About Home Performance (Podcast)

In today's podcast, I talk with Corbett Lunsford about his new show about home performance and diagnosis. Home Diagnosis airs on PBS in winter 2018. Even though Home Diagnosis mostly deals with building performance, HVAC work is a large component of overall home performance. Corbett Lunsford used to be a pianist before becoming a building performance expert. He […]

Blower Door Testing, Building Performance & More w/ Corbett Lunsford (Podcast)

In this podcast episode, Bryan talks to Corbett Lunsford about blower door testing and the coming building performance revolution. Building performance and HVAC have been becoming much more closely linked lately. So, it's a good idea for HVAC techs to learn a bit about building performance. In the HVAC world, we often see homes with […]
