Wow! There seems to be a difference in opinion/interpretation governing refrigerant leaks and the legalities of "gas and go". I confess a level of confusion and ignorance due to the fact that I got my EPA card before they were required and haven't kept up on the laws. (Yeah I'm old) I was led to believe and have always operated under the rule that you can charge a residential system one time and after that if the system lost 15% or more of it's capacity you had to find the leak and repair it or replace the system.
I know about the 50 lb or over law governing commercial systems but have encountered varying interpretations concerning residential systems. I haven't read the actual EPA law as I'm sure it's in lawyer speak.
So if anyone knows the EPA law and can explain it so dumbies like me can understand it please do so. Please no "opinions" just the actual legal interpretation in laymens terms. Thank you!
