    Collectors/Hobbyists

    Here is an odd question. Do you ever pic up old AC units, fridges, etc. and take them home to fix them up and covert them to non R-12. R-22? People collect everything from matchbooks, barbwire and huge old casino signs.

    I got nothing collectable, but I was given an old AC unit that fit on top of an old RV. The shroud it gone, and it was a shop trainer for YEARS, but it works. The instructor spotted me some virgin R-22 instead of the reclaim tanks we use in class. Did a tripple ripple dipple evac on it and got it zeroed in. Plenty of cold air comming out of that unit. Just have to fab a cardboard stack for the condensor fan to vent out the window. I'll add photos later.

    Who wouldn't want one of these babies restored and in your window. Why, it's a regular conversation piece.

    There was someone restoring an antique fridge that posted on here a while back. They put up some pics, it was pretty neat

    I used to convert a few of the old refrigerators from R12 when doing leak reapirs for people with more money then brains. I've never come across any units that I thought would be worth dragging home and trying to fix up.

    Common sense isn't very common anymore.

    That is the problem. They are bulky, but smaller than cars

    I hauled home a couple R12 mini refrigerators that I was going to restore for around the house, but got rid of them after 6 years of tripping over them. I repaired one, but it wasn’t efficient enough to keep around with the high cost of electricity in my area.

    Now i have took an old unit and air handler for 22 and mixed 410 in it just to see what might happen ( i got a building at my house where i did this it wasnt a customers house i mind u). So far it cools pretty good. Gonna try a heat pump this winter and i imagine its not gonna work as well. I know they say not to mix, but ive never heard a reason... So im gonna try and see why!

    That's cool. I look at all these old units, and the handy part in me wants to fix them all up. Especially if they an old look to them.

    R-22 and 410 are close on the cart. 30ish psig difference. R417a claims to be a direct substitue in most cases. only 20ish psig difference. Worst case you replace the TXV or modify the length of the cap tube to zero it in as close a possible.
