I always see this advised for turning A/C Units into chillers. Maybe a Home Depot link or something would help me. The tubing to be bent looks awfully thin. Ones I've seen are over $50 so I'd want to be sure I got the right one and I'm assuming this is a ncie tool to have for other projects?

I have read the faq but have been mulling stuff over. Hopefully a few other quickie q's about stuff Ive forgotten may be acceptable. I guess if the tubing were to break it would be cheaper to just get another A/C, but how much would a simple hobbyist need to spend to get involved in building there own? I see people usually have brazing equipment, some valves, and I guess another compressor can be used as a vacuum + Im sure other stuff (See I read!)

I had my eye on a $80 A/C unit from walmart... 5000BTU... should I be wary of one that is too cheap may have a weak compressor? If soemone just picked one up and it worked great please lend a suggestion for one that is friendly for conversion. I guess if I buy one, I can then decide between it and the kenmore already in my room.

I have read but I am a slow starter. Still trying to figure out the best way to get into this subambient stuff. This will help me. I did a search for tubing bender but would like a little more specific advise. If thats the only answered question I'd be happy.

A 'three in one' bender is most versatile. Using a tubing bender is fairly easy with a little practice. Unbending is much more difficult and prone to breakage than bending. And the connections at the ends are the weakest point in the tubing.

As for the compressor on cheap A/C unit, well most of them seems to be cheap but they have some awesome cooling power, some people here managed to make waterchiller out of them with around -25C.
And Gary said once tweaked they could get even lower.

DO IT!!! :P
