Probably be cheaper just to get the proper unit
I went through hvac/r schooling over 10 years ago. I realized quickly in my location focusing on the sheetmetal side (duct work) was more profitable for me. I still do occasional residential servicing for friends and family but I've lost a lot of my schooling and I'm looking for a little specific info.
I went to a building demo and got a brand new water source heat pump for very inexpensive. the foreclosed house I bought has a 20 year old and sickly 3 ton air source heat pump in it. I figure rent and excavated the back yard and put it in.
The unit is a 2.8 ton 460/3 phase indoor unit. I have done a month of research and have a clear idea of the magnitude of work to get this unit running but I still cand find some specific info.
They make this unit in a 230/1 phase. My question is if I replace the compressor, contactor and fan motor as well as a off the shelf 120 to 24v transformer for the board and other controls will that work. And would I be better off buying a 3 ton compressor rather than a more exspensive 2.8 ton as long as they are both scroll type and of course 410a.

I don't see why it wouldn't work. Most nominal 3 ton units these days have a 32-34kbtu compressor in them for efficiencies sake.
As per forum rules we can't discuse numbers but I can replace these components for about 1/5 or less than a new one.
Another solution would be to install a VFD. They make some that are designed to take 230/1/60 and convert it into 460/3/60. Its not the most efficient solution but it would probably make for an easier install.
