Does it matter what brand a compressor is if it's aluminum or copper wire? The central ac's I got are mostly bristol and 3 copelands. Not sure about the window ac's yet. I got a Milwaukee sawzall cost me 139 and some Diablo blades 12in some medium metal some thick metal bi metal maybe I shoulda went with the carbide ones?. I used a carbide medium blade on one today never did that B4 always used a hacksaw haha took me two days with a hacksaw and very exhausting not all the way through mind you 4hrs and 4hrs. That was years ago. So i figured since I got 10 central ac and 27 window and 1water cooler compressors to do that I'd try my had at a sawzall I'm sorta afraid of sparks haha so I don't like grinders. I started at the weldline the the cut line looked like a spiral ham haha started low then went high near the top haha. Cut pretty good I thought took me a hour to get the motor part out only because it didn't cut straight and plus I had a screw that wasent cooperating I got 3 out then had to use channel locks boy I got lucky on that got motor out it's 26lbs 15oz haven't broke it down yet going to wait till I get them all into motor piles then break them down. I got fan motors to do also. So I like the sawzall like a can opener haha.
