I am making a career change - have worked the last 5 years doing Technical Support for 3Com (troubleshooting Ehternet and TCP/IP issues on Layer 2 and 3 Switches)- and I'm going back to school for a double-major A.A.S. in HVAC and Computer Aided Drafting.

I am more interested in the building automation and design side of the HVAC/R industry and need some direction on where to find the best book(s) on the topic and where and what types of jobs are/will be available with my existing and newly aquired skills.

Regards,
