Because it has had freon in it.
I would be pissed if someone served me beer made with contaminated equipment.

Supposedly freon goes away completely. Just for the record, this was not anything I was considering seriously. It's always better to get the scrap money.

I'm not sure about home HVAC but in automotive AC systems oil is mixed with the refrigerant gas to liberate the compressor, it would be impossible to determine if ALL the oil had been flushed from the lines.

I'm not trying to smart A$$ but I wouldn't risk any chance introducing bad chemicals in my beer. I would feel bad if someone got sick from drinking it.

Maybe the lubricating oils in the freon can be washed out. Maybe not.
I would scrap it and get some fresh copper.

I'm glad this discussion was had on this forum. I read on a distilling forum where a few individuals said yeah go for it.(not to me, just on the thread) I think what started my thought process is someone mentioned using scrap copper they found. Is it really possible to clean the inside of a copper pipe that well? Prob not.

Copper is Not that expensive to risk messing up a log brew day and or potentially getting someone sick.

If i was looking at saving thousands of dollars, then MAYBE i'd put some weight behind possibly cleaning it.

But your saving $30. Just get 1 less coffee a day and your there in a week.

Default Bobby_M + Beer Canuck + another stage =

Loved Bobby_M's idea and Beer Canuck's "whole works in a bucket" approach. It's 70ish and sunny today which is a lovely day for DIY, but is also a harbinger of impending summer and the mid 70s groundwater temps it brings here in the south. I was worried about reusing the copper from my first homemade immersion wort chiller (already had some kinks started and figured more bending wouldn't do any good on that front). But, it was still plenty fine for a pre-chiller for that dang-near-already-steaming water we get coming out of the tap. Since I planned to put the whole works in a bucket a-la Beer Canuck, why not have that bucket full of ice water and pre chiller? No good reason I could think of.

So, tap water goes into the bottom of the bare coil (red hose) and exits the top of the coil into the counterflow chiller. I'm sure there's a more elegant and/or effective way to do this, but ran the wort out tube through a hole in the bucket and scooged the thing shut with silicone. A hand tubing bender was essential (about $16 at lowes) to make a couple of tight bends to line everything up without kinking. Yes, there's pretty nearly a kink near the top of the pre-chiller. Don't judge me.

Haven't tested with ice water, but 200deg wort in (water for test) comes out 65 with 59deg tap water and valve on the kettle about 2/3 open. Hooked the output to a lawn sprinkler. I've named it Ghostface Chillah...

I'm thinking of adding a thrumometer to the output along with some sort of venturi apparatus. By thrumometer, I mean a cheap stick on fermometer stuck to something suitable.
