Neal Lewis Posted July 16, 2015 Report Posted July 16, 2015 Does this green oily substance indicate a Freon leak. Or is this stuff used for leak detection? Thanks Click to Enlarge 48.58 KB
kurt Posted July 16, 2015 Report Posted July 16, 2015 I think the old refrigerants used an injected dye so leaks could be identified, and that dye color is usually an iridescent green. Freon is colorless, or so I've been told. You might be seeing some residue from a dye injection. I'd bet a tooth it isn't flux.

I sure would like to have a tooth as a trophy.
Erby Posted July 16, 2015 Report Posted July 16, 2015 I'd bet it was condensation taking some of the copper minerals with it when it dripped off the uninsulated refrigerant line. I've seen some around here where the refrigerant line doesn't fully cover the line (a 5 or six inch gap) feet away from the unit or any need for soldering. Just a solid line in that area, but the green stuff is still there on the insulation with no sign of a refrigerant leak. I've also seen the same green under copper water lines with no solder anywhere in sight.
kurt Posted July 17, 2015 Report Posted July 17, 2015 I get to keep the tooth if Erby's right, don't I?
Erby Posted July 17, 2015 Report Posted July 17, 2015 So tell us Marc, refrigerant line missing 6" to a foot of insulation in a straight run across the attic, no soldering anywhere near it. The same green stains on the wet fiberglass insulation under it, water dripping off the refrigerant line from condensation. Where DOES the stain come from? Don't leave Kurt's tooth hanging in the balance!
kurt Posted July 17, 2015 Report Posted July 17, 2015 There is sort of a drip pattern down the side of the side of the cabinet, a what looks like a drip epicenter there under the copper. Could be. Maybe not. I'm keepin' the tooth, regardless....

Don't leave Kurt's tooth hanging in the balance! Are you sure the liquid and vapor lines are not soldered just outside that unit? Also, dye is inserted at the schrader ports on the outdoor section. That's usually the only place where ports are installed. The stains could be the colored soap that techs use sometimes to check for leaks. It bubbles up at leaks. It would drip that way if sprayed at those solder joints. The brand I use now is approximately that color. I mean, how else is Kurt gonna keep that tooth? And who's got the gumption to go over there and knock it out? Marc
Neal Lewis Posted July 17, 2015 Author Report Posted July 17, 2015 The suction line was insulated very well. The green goo was definitely oily or sticky.
John Kogel Posted July 18, 2015 Report Posted July 18, 2015 It is definitely a mysterious green liquid that has dripped down from the lines. I'll take the tooth, most correct answer.

Erby Posted July 18, 2015 Report Posted July 18, 2015 Didn't really need to do that, Nolan. It was Kurt's tooth they wanted anyway, not yours. And then, they only wanted ONE!
Nolan Kienitz Posted July 19, 2015 Report Posted July 19, 2015 Heck, Erby, I thought that was an image of Kurt that I found!! [:-monkeyd
