dual capacitor ?

[AC5096]

That works, but if/when I need to calculate something like that, I just use a scientific calculator and enter it all as one equation.

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

completely agree with last reply. with the addition of furnaces coding out and the tools that are out today, everybody thinks theyre a hvac man. Whered the art of it go????

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.

Mounting caps terminal side down stops water from collecting on the top and shorting them out. I give the tech credit for knowing how to obtain the 7.5 mfd but it does look very unprofessional.

According to AmRad, the preferred mounting direction is with the terminals up.

There shouldn't be any water collecting on the top....

When does 5+3=7.5?

Close enough

I must admit I have made up a capacitor many times when your 300 miles from a supplier and the customers ice cream is running out the door you have to do something...

Chinese made run caps!

4.75 + 2.75 = 7.5

I see what you did there... Now that's funny.

the duct tape is hackery.
.

Although I have seen ducts made of duct tape, so maybe that is the reason.

I cannot believe that someone out there actually put a 5 and a 3 together to make a 7.5, wrapped it with duct tape, charged the customer and can sleep at night !

I wonder if they charged big bucks?

And if it was a better choice quadrupling the time spent-at least making cheesy terminal connections when the correct cap was less than the price of two?

Sometimes people work too bleep hard to be stupid!

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?
