As a service technician it is
imperative that we adopt a set of service procedures that we employ on
every service call. Repetition
is a powerful educator and by using these same service procedures you will
become more efficient, confident and skilful. The following are a few
procedures and service tips that some technicians employ, take from these
and edit them to suit your needs.
| Regardless of what you service
weather it’s a water cooler in the hallway or the 500 ton chiller
that cools the building, all calls start the same way, by the
placement of a service call. If your are the one to speak with the
client great if not and when available call the customer yourself,
first off it’s great pr second and most importantly you are able to
ask him a few questions regarding his 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 logical possibilities for the
task at hand. Some technicians arrive a job site and wonder where to
start, you will know exactly where to start and most likely this is
where you will finish. |
| After checking in, head over to the
thermostat or the main controller and have a look at it make note of
its setting (too low, freeze up?) if it’s an A/C system on a
thermostat, turn it off then back on and listen for the fan to start.
(if now sound check power before heading to the roof). If a computer
controlled system make note of the supply air temperature and how many
stages of cooling are running. This may sound trivial but its amazing
what your eyes and ears can do for you. |
| Your eyes and ears are far to
powerful a diagnostic tool not to utilize them, prior to and after a
call spend just a couple minutes looking, listening and yes even in
some cases smelling. i.e. – on a call with nuance flame failure’s
have a quick smell of the combustion products, ok its not accurate but
it sure is effective at telling you if the air to gas ratio is close,
I can’t being to think of how many rooftops I have seen running
where the products of combustion were severely sharp. |
| Know what the equipment is supposes to
do and what the sequence of operation is if you are unsure call the
tech support line, its fast and efficient. |
|
 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.
