Looking at the way things are changing with regard to AC and R control system I can see more and more computer software personnel entering our fields. They have made our jobs more comfortable by making it easier to monitor large HVAC installation by just sitting on a table in a nice cool office, instead of sitting in a room with huge panels with lights and Ampere meters. I think I owe a Thank You these guys.

They may add tons of software , but I feel that they have made us a little lazy too. .
