I'm trying to build a combination water heater/air conditioner on the cheap. I already have a 5,000 BTU compressor, expansion valve, filter, etc. The condenser will be a coil of copper tubing in a container of water.

What I don't have is an evaporator. I'd like to try and use a cheap automotive evaporator core, but, they all have odd non standard connections on them.

I'm wondering if I bought a cheap core like this:
NEW Ford Escort 1987-1990 GL GT LX Base A/C Evaporator Core 54439 OE | eBay
Can I just cut the ends off the aluminum tubes, flare them, and then use standard flare fittings to attach it to the rest of my system?

I suppose it's possible to just braze it to some copper tubing, but, I don't really want to try and braze aluminum.
