What happened was I started answering, backspaced through it all and said screw it. Try the search mechanism next time before asking. Brazing with oxy/acet, air/acet. should never be done without flowing nitro through the lines. But you knew that already, either from working on cars a/c or from reading the thousands of posts regarding it's necessity. This is such a basic concept that ANY company worth it's sand will do this when installing lines. In 16 years, I have never seen it done without it. Is there really a geographical island left within the US where it's impossible to find a reputable company? Usually it's a question of going with a low bid and then standing over a cheap hack's shoulder telling him his shortcomings--trying to make up for his low-cost-low-knowledge approach--with your supplemented rudimentary factoids like the one posed by your initial question. Go with a reputable company and you can sit on your couch sipping a beer as cool dry air wafts throughout your house. Nitro pfftt. That's why you hired someone. When I have a mechanic work on my clutch, I don't need to know how tight the nuts on a bell housing should be. I go with a past-history, referred mechanic and have never been sorry. Of course...it's never the cheapest. So go ahead and post now how you've tons of bids, carefully selected the mid-cost one and that this response it totally outrageous. Should've let this one die....

Drcustom, I am not sure what you are trying to communicate to me by the statement "Doubt he needs you to tell him if they're reputable." Please clarify. It does not make any sense.
