Is there still freon?
 
We had the furnace replaced last fall. When we did, I asked the HVAC guy to disconnect and remove the old coil. He did that and told me he also drained the system of freon (re-captured?) before he removed the old coil.

The old condenser is just sitting outside waiting for me to remove it. As an electrician, I know the value of scrap copper so I was thinking of scrapping the condenser. Would the condenser still have freon in it or would it have been removed when the HVAC guy took the freon out of the lines?

It may, depending on how the HVAC guy went about doing things. It's possible they simply pumped the refrigerant back into the condenser, but they may have reclaimed it (i.e. removed it from the system).

Julie,you disapoint me.As an a electrician,you weren't grilling him or have contacts?

if the allen key servcie valves are fullCW all the way down the condenser was isolated with freon.if the line were just cut away at the condenser it is atmospheric....might consider selling it on CL if the valves are shut with freon holding the condenser positive if it is good shape

Bob, at the time I was thinking I could use the old condenser but later learned that R22 & R410 are very different animals. As far as contacts, I have them but they all work commercial. A 3 ton condenser is like a flea to them.

When I found out the old condenser was useless to me I looked into is it worth it to scrap it? Then I saw a video on YouTube where some kid scrapped a condenser and at one point released the freon into the air, even though the unit was completely disconnected and out in the middle of nowhere. That's when I wondered if there could still be freon left after the HVAC guy reclaimed it from at lineset.

As far as the kid, don't worry. He's fine. He covered his mouth and nose with his T-shirt to protect himself from the freon. :thumbup:

Biggles, I have a feeling the unit is pretty much gone. It's at least 15 years old. If anyone bought it they would have to be pretty good refurbishing old condensers. It's probably worth more in scrap.

crack the larger copper line service valve with a wrench or allen key see if it burps freon..that is the gas side of the condenser the other thin copper line is liquid if there is any within

10,000 dollar fine if released into the air....Iam already sending the freon police to your location....:laughing::laughing::laughing::laughin g: unit is filled my guess...

Oh, so that's why those helicopters have been circling my house!

I opened up the panels on the unit and found both valve caps were loose. I could remove them by hand. The HVAC guy must have done that.

I waved the choppers off.

Now the scrapping investigation begins. Will it be worth it?

Its not just the valve caps...is the valve stems under those caps all the way to the top or are they bottomed out? The choppers might be back. :)

Scrap is worth it for some pocket change.

The lines were empty. When we ran it last summer it didn't work at all, so I'm guessing there was a pinhole or the guy recaptured whatever was left or both. No stormtroopers knocking down my door.

I tore the thing down, piece by piece. I separated out the metals. Even if I was able to separate all the copper from the fins, clean off the solder and make it all #1 there might be 10 pounds there, maybe. But that's not happening. I figured I could get $15-20 less the cost to drive to and from the scrap yard. That would deduct about $10 from the big kill. With the remaining windfall I think I can buy a Margarita, two on 2 for Tuesdays.

There's an old guy who drives the streets here looking for scrap. I gave him some unistrut cut offs one time and he was happier than a... well, you know what I mean. I'll keep a lookout for him and make his day with the AC scrap.
