Ductless Heat Pumps for rentals and personal residence?

[Jeff S.]

Just starting to research ductless heat pumps and wanting to get BP's take on what kind is best and some feedback. The properties are for: 1) 650 sf upstairs unit in a duplex; 2) 1650 sf ranch style (one level) and 3) 2400 sf ranch style. Portland OR temps range from 20 to 100 degree fahrenheit.

Most furnace people aren't that hot on them but replacing a new gas furnace AND a new air conditioner is huge (14K) when a ductless can run cheaper purchase wise (4k) and efficiency wise.
