You are in a similar boat we were in when we replaced ours. We were quoted $3500 just to replace the aging (undersized) outside unit. That was to keep the unit inside and the LP furnace, which really needed replaced anyway. We ended up going geothermal for a total of < $10k after rebates and 30% tax incentive. It's nice to have that 10 year warranty that came with our WaterFurnace too.
