Changing Compressor

The compressor on my AC unit is dead, and I'm looking to buy a new one and have a local HVAC contractor remove the old one and install the new one.

I was told that the new unit has to be the same model number as the old compressor. This unit is from 1999, and I'd be a little surprised if the compressors still have the same model numbers (but I've been wrong before). Does that sound correct? Otherwise, and suggestions where I could source a new one (aside from a HVAC contractor) or a used one?

I'm really just trying to do this to get through the summer, and see where things are in the Fall. Thanks for any suggestions.

You should be able to find the same model# if it's a Copeland. I have bought them off Ebay.

What exactly was the test to confirm the compressor was dead & unfixable?

Several tests done by 2 technicians. The second tech used a box with a crank to run a current through the compressor and he used a "booster" on the capacitor to kick start it.

It's a Trane compressor. Does Trane sell them to consumers, or how can I get one?

I've seen several used ones for the same size unit (3.5 tons and using R22), what else would I need to know to make sure another compressor is compatible?
