Most likely low 134 level won’t activate the compressor. Once all is up and running also a good habit is to run the AC, needed or not, to self lubricate the compressor.
I had mine done 2 years ago and that was 10k with ceramic in Huntington NY. They guy was such a perfectionist he didn’t like the downloaded templates and did it the old fashioned way. Incredible job and worth it imo!!!
