· Regardless of what you are repairing from a cell site to a 100 ton chiller, all calls start the same way, by the placement of a service call. Get all the info you can from the dispatcher and when available talk to the customer yourself, first off it’s great PR, second and most importantly you are able to ask them a few questions regarding their problem. On you’re way to the service call you have some spare time and with this information you will be able to come up with several possibilities for troubleshooting your call. Some technicians arrive a job site and wonder where they will start, you can know exactly where to start and finish. 

· Know what the equipment is supposes to do and what the sequence of operation is if you are unsure call someone you has already been there, or call the office.

·  Don’t let yourself get bogged down looking for ghosts, Some of the equipment we work on have several problems, stay focused and solve one at a time, if you start looking at different problems you will get confused and frustrated.

· It could be an residential condensing unit, a ice machine, a walk-in freezer or a 100 ton chiller.  They all work with the same principles, pressure and temperature.  Your most valuable tool has got to be your P/T chart.  Keep a P/T chart with you at all times when troubleshooting, most of the time it will tell you the problem.
