Looks like an experienced Goodman installer tried his skills on a commercial job!

looks to be a small oil stain there. so he was guessing that there was a leak.
I've had my fair share of fixing leaks in that exact spot.
Sometimes you get the other Voyager variety where the distributor tubes coming off of the OD TXV will rub and leak. All my experience on leaking tubes on Goodman Heat Pumps prepared me to fix them in the Tranes. At least Trane made an ATTEMPT to zip tie their tubes so they wouldn't rub holes in themselves.
