Need a Free HVAC Computer Program

[chicopee]

Would anyone know of a web site providing a free program to size ducting and equipment for heating and cooling of a multiple story facility. I dont want to reinvent the wheel for such a program.

Well, McQuay has duct sizing, pipe sizing and psychrometric programs at:

And Slant Fin has a free heat loss program, at:

But for a real heating and cooling program, you could try Elite software. Which isn't free but offers partially functional demos.

Best of luck.
