Do standard calculators have a reciprocal key? Pretty basic math wouldn't think one would need a scientific calculator.
All I have is two old TI scientific calculators
I just open the calculator app on my iPone and turn the phone sideways, instant scientific calculator that has a reciprocal key, as well as some other functions that occasionally come in handy.
It isn't that the math is hard, it's just faster to input directly and hit "=".
Same for psychrometrics calculations.
Sure, I could take all the measurements, then sit down and plot everything out on a chart, then do the math on paper.
Or I can open up Psyclone on my phone and input the measurements as I take them, and have the results instantly.
It really is not a hard choice, I've got **** to get done, so the phone app wins every time.
If more government is the answer, then it's a really stupid question.
Professionalism is not a word that is used very often in HVAC. Its hard to maintain a positive outlook on what we do when over half the industry are all hacks. They make the same money per call we do and the end result looks like this picture shown above. Most customers complain over price so they call they guys who do this level of work. If you do not posses a inner drive to do a good job this industry will often not inspire it. (Present readers excluded)
I'm sure hacks will hack on, earning beer money, pretty decent beer money at that for folks who are only looking at price. I always educate on what I am doing and why it is the way to do it when I work-when the homeowner watching. You don't have to say anything bad. I don't. I just keep educating and informing and planting land mines. So it may make people think twice about having the $peanuts a call guy, or their brother in law, or their neighbor who has been to school but just doesn't have gauges..... touch their equipment.
Would you trust your car to a half wit who puts things together with duct tape for $peanurts a call or something like that? Or could you see that having someone with the right tools, skills, etc. should be working on that multi thousand dollar system you depend on for your life and comfort?
