yes it is, my respect for you just went from squat to squat and a half.........just kidding, thats is what ive noticed in this site is that if you are not careful you will either be judged or in rare cases complimented for your van organization, tool, or tool bag that comes out in the background.
I was called out to an old church on an a/c unit several years ago they said hit jus need a little juice. head pressure 350 suction 20 condenser clean went inside to check txv and there was none liquid line frosty. crawled under church to find 60 feet of liquid line pinched about every 6 inches to act as a cap tube. one of the members had bought the unit at a yard sale and installed it him self. I gave them a new a coil I had laying around and just charged then for new copper and gas.
We install these all the time there called progessive reducing rigt angle zee traps they reduce compressor failures by stoping all the gravel in the lines from feeding them under the house with open ends . It's easier than taping them up you know.
