@lovelorn8888 If you can do basic adding, subtracting, multiplication, division and fractions, you'll be just fine.

If you have an iPhone you can get a series of programs..

HVAC Buddy (superheat/subcooling calc) .

PT Buddy (has like 700 refrigerants)

HVACDuct (ductalator)

I'm new school, card board calculator!? no way! :-D

BTW, I work on computer room air conditions so you can see how I'm a techie.

@orbtaybal Thanks for the info. I'll check to see if any of these programs are downloadable through my htc Droid.

@DrZarkloff yeah I can LOL But some of the math is harsh... more like the Formulas

Like I hate trying to figure out how many BTU's it take to say cool meat thats 70 down to like say 5 or whatever Thats what always gets me

You had me confused because you said .25 friction rate and went with .05 friction rate to 800 cfm, and mine wasnt matching up.

[jjpjjpjjp1]

If a furnace is rated at .03 ESP, where on the chart do you line up the chart?? AND... how come there is 2 scales for friction loss on the ductulator????? This stuff always concerns me. Is it .05 on the lower scale or is it .1 on the lower scale for friction loss???

@DrZarkloff Well I trust your knowledge over my own, but I've never seen matched units put out over 400cfm per ton. But I guess that why I hate rules of thumb; they always change depending on who I ask. Thanks for the insight, keep the videos coming.
