Great HVACR Software Links

Katmar Software (Free Software) Various engineering software applications.

Paul Milligan (Free Software) Paul originally setup the two newsgroups alt.hvac and sci.engr.heat-vent-ac. Paul and Andy Shoen co-authored PMTherm.

Andy Schoen (Free Software) Andy, as I understand, does much of Sporlan Valve Companies R&D. He would have written much of the software and literature available on the distributed Sporlan CD. Andy has developed a neat little refrigerants properties application too.

Randy Wilkinson (Free Software) Randy has written some really handy hvac software much of which he gives away for free.
