Summary

Many techs have said, "That's the first thing you should have learned in school." In today's short podcast, Bryan talks about the four rules that have his vote for the first things to learn in school.

These four rules don't just apply to HVAC work; they apply to science and the world as a whole. They describe how the forces in our world work in our HVAC careers and our everyday lives.

The overarching theme of these rules is that high goes to low. Gravity is the prime example of this rule; if you drop something from a high place, it will fall to a lower place. There is a potential energy difference between high and low, whether you apply that to a ball rolling down a hill, voltage, or a sine wave.

The first rule is that high pressure goes to low pressure. The compressor applies lots of pressure to the low-pressure refrigerant inside of it.

The second rule is that high temperature goes to low temperature. We transfer heat from the inside of the house to refrigerant inside the evaporator coil. (Remember: temperature is an AVERAGE measure of molecular activity.)

The third rule is that high voltage goes to low voltage. Electrons move from the higher energy state to the lower energy state.

The fourth rule is that high humidity goes to low humidity. For example, two air masses with different humidity contents can be separated by a cloth. The higher-humidity air mass will diffuse some of its moisture across the cloth to the lower-humidity air mass. This process creates a stasis across the two air masses.

Everything in the world tends towards equilibrium.

0:00.0	Hey, how's it going with you in your life? How are things? Summer's here, it's hot, working long hours probably if you're in the
0:12.3	HVAC industry, which I assume you are seeing
0:14.1	as how you're listening to the podcast that helps you remember some things
0:16.2	you might have forgotten about HVAC as well as helps you remember some things you forgot
0:19.4	to know in the first place. I am Brian and this is a short episode. This short episode is about the things
0:24.8	that you should have learned right off the bed in school. A lot of times guys will say
0:28.3	that to me, they'll say no matter what it is. If I give a tech tip about pulling
0:31.4	the wheat ports out of a condenser fan motor, for example,
0:35.0	they'll say, well, that's, you should learn that your first day of school.
0:37.0	Apparently the first day of school should have been very long, because I've got a very long list of things that apparently everybody should have learned the first day of
0:43.3	school but if it was up to me if I was in charge of a program this is actually what I
0:48.6	would teach the first day of school so these rules, if you will, these four things are the things that I would say are probably the most important for you to start off with if you're getting in the HVAC trade. So let's see if you agree.
1:01.0	Anyway, before we get started with that, though, I want to give thanks to our great sponsors,
1:06.6	which are quite a few nowadays, but I'm very thankful for that.
1:10.5	Mitsubishi Electric cooling and heating, carrier, UEEI in the Hub Smart Kit and the WRS scales.
1:17.0	Refrigeration Technologies at refriggedech.com, makers of all the Viper products that you love so much as well as Nylog.
1:23.0	American Rad, Amrad, the Turbo 200.
1:26.7	Find out more by going to American Radionic.com,
1:29.5	Air Oasis, makers of the bipolar and nano indoor air purifiers.
1:34.0	True Tech Tools, not a sponsor but a big fan of True Tech Tools.
1:38.0	You can find it more by going to True Tech Tools.com for all of your tool needs,
1:42.0	as well as Retrotech, makers of Bloor doors, Duck Leakage Testers,
