Pros: you could keep your vehicle stocked with a wide variety of parts and materials, you could pre-stock your truck on freon.
Cons: office would send a tech to pick up preventative maintenance parts for multiple jobs, but when a different tech was dispatched to the job, the office did not know who they had sent for the parts.
A typical day of work was to work til you drop, into the wee hours of the morning, drive home dead tired, to get up in a few hours to start all over again. Weekend calls from dispatch when you are not the on call tech.
I learned that if I see their number come up on my phone; I will not answer. They do not care if the job is done correct, only that you do it fast. They want you to find the least little thing, even if nothing is wrong with the units, so that they can charge extra.
Management - wouldn't waste a bullet on them, plus one of management was having an affair with office worker. She could do no wrong. Even the local supply house did not want to deal with the office.
Co-workers felt the same as I did, and given the chance they moved on.
The hardest part of the job was dragging tools and tanks up the side of the building without any help.
The most enjoyable part of the job was my last day!!!
