New guy(my bro-in-law) did his first coil a while back. Mortex, mobile home coil. Unit would pump down on start up, so we checked for a kinked lineset under the trailer and whatnot, then concluded that the txv must be bad. Swapped it out with a txv i had in the truck but it still pumped down instantly. Ending up finding that this goober bro-in-law of mine forgot to cut the copper endcap off of the suction line outlet. But it appears he ran nitrogen while brazing at least, nice and clean inside.
