Thanks for that PPCFreak.
I checked that one out and it looks like a great program with a lot to offer and for .99 cents, despite the ad thing, is a great price.
Not to long after I made this post though I found and tried out this program:
Fann Software
And did the demo and it has a lot of great stuff too so I bought it shortly after.
But it does cost a bit more at about $8.95
The one thing for me that is great of it though is I often need to convert Watts to a BTU load number which isn't really all that hard as you just multiply the watts x 3.41 then divide that by 12,000.
But in the hustle an bustle of banging numbers around, its nice to have something that does it directly.
But other then that, that program you linked looks like a really great one too, with features mine doesn't have so for that price, I would recommend trying it.
Thanks again for the help.
