I have been doing this for awhile now, though screw ups still eat at me. I had to change a pressure transducer on a Bosch heat pump yesterday and I must have got it too hot and melted the plastic on it, doesn't help it's in a terrible spot in that condenser and it's like a 3" stub they expect you to not overheat but I don't like making excuses and hate when things don't go right.

We already had to replace the a coil on this system a month ago because it was leaking so the customer is pissy and I know my boss isn't that mad at me really, he said they put it in a terrible spot to braze, I just have a hard time not letting things weigh on my mind.

I'm sure I'll feel better in a week but this week was a pain, I do plumbing too and replaced a sewer line on Thursday, so I was already exhausted. I'm sure it's not a new thought but holy hell do the trades take it out of you sometimes.

Anyways just venting a bit I guess, it's not a huge mistake really but still bugs me.
