    Lineset insulation

    got a 2' section of 3/4 copper pipe near the outside unit that doesnt have any insulation, is the insulation actually necessay? Does it serve any purpose other than keeping the pipe from sweating?
  37. Any difference in: ac techs or installers?

    guess what im asking is a license required for anyone to work on any part of an AC or heat unit. And are some that work on residential units more trained than others?
