How many times have you removed the valve core on an AC unit then not been able to get them back in?
What did you do to get them back in?
The reason that I ask is the guy I work with says that getting them back in is hard and they screw up alot. It is better to just not touch them at all. I have alot of exspierence with valve cores cause I was a commercial service tire guy for 5 years before I switched to HVAC. I never came across a valve core that couldn't be fix ( re threaded)
So is it as bad as he says it is? Should I buy a set of CRT and start using them?
