Who says things were done better 20 years ago?

I think that big loop helps shoot the oil back into the compressor.

Installer was a big roller coaster fan!

I haven't seen one of those Coleman units in 20 years!

I'm coming to the defense of that install. I believe that is a pre-charged line-set. You aren't supposed to cut those. Therefore, any extra line-set that you have needs to be left coiled up in a big mess. That's the way they wanted it back then.

I've heard tale from the older guys about such things. How did one go about connecting the lineset and releasing the charge?

It's just a version of an inverted trap!

A really crappy version.

I would still take the extra time to cut it and make it look nice. I'm OCD about things like that.

They could have at least tried to use a bender on it.

You would have been screwed if you cut it. The line sets weren't copper. If you cut them they were ruined. If I remember correctly we could get 25, 35 and 50' sets.

Certainly wouldn't have been the first thin I screwed up doing this type of work. Obviously I've never used them and never will.

So was there a flared/compression type fitting that held the charge until you tightened the joint? I can't believe those things lasted too long...maybe meant for builder installs?

Are you talking about those flexible liquid lines they used to make?
I ran into that once in a concealed application. Not to happy.

We used all sorts of precharged line sets, they were all copper, Aeroquip fittings on the ends. We cut them to length, soldered them back together, vacuum pumped them and thighetened them up. Never had a problem.

The only problem with them was the Aeroquip fittings didn't like to seal if you took them apart and tried to put them back together. For some reason it seamed liike half the time they would leak the second time around.

oh, you yungins got a lot to see, wait until you cross a lennox that used the liquid line as the metering device and there is an extra 20' of liquid line


at least they followed mfg instruction an d sloped the lines and didn't stand them vertical

yea they could have made it look a tad better (not by much though)
