my ignorance of that tool (which looks pretty cool,) doesn’t equate to ignorance of a/c repair- and my 20+ years of doing a/c repair verifies that. I’ve just apparently not had the overwhelming need for a tool like that.
anywho- You got me on the valve core leak. Good for you. I’ll go put some aloe on that wicked burn.
(I see what you are nitpicking at me for now. I said vacuum then look for leaks. You are correct- check for leaks with the refrigerant in the system.)
But, my original point still stands. OP has added refrigerant to their system, and still has an issue. From where we are- we don’t know if too little refrigerant is now in the system (leak,) or too much (now overcharged.)
My post #7 said that after a leak is found- “All that is going to have to be done.” I stand by that. If you want it fixed correctly, then the proper steps need to be taken.
Carry on with your nitpicking, and thanks for the tip on a tool that I don’t have!
