I'm not looking for an illegal copy if that is what you are implying

 

Cook has a duct calculator as part of their "compute-a-fan" software. I use it all the time.

http://www.lorencook.com

 

That link doesn't work for me.

 

No,that is not what I meant concerning your question.

(I however,will take what I can get any way I can get it...well as regards my question that is)

I do think I have seen what you are looking for somewhere.I will keep looking.

 

Free downloads

Here ya go:
http://www.maquay.com/

I never heard of an "illegal ductolator",but be careful just in case...

At first I thought you were being sarcastic, but I see your being helpful. Sorry about that.

I also found this one if anyone is interested.

I looked at the Maquay one and it's close to what I want. Mainly I want equivalent rectangular sizes. I can't follow those curved lines like I used to.

 

Duculator

Where could I find a duculator that could be downloaded to a Palm

 

Yes.

Duct design

Have a look at www.casadometal.com free software downloads. absolutely no charge whatsoever! If you like the
software send the guy a drink (or the price of a drink).If you are unhappy send him the complaint.

 

try www.calcuduct.com

 

The AC company that is doing the work is telling me they were actually ordered to under-size the unit a little... that I really should have had a 3.5 ton minimum which means 4 ton.

That said, I got a 3 ton, so I just need more return air right?
