Avoid basement AC units and heat-pumps?
I keep hearing sad stories about basement AC units and heat-pumps being hard (and therefore expensive) to service and failing after a few years. (Many tell of seeing Alfa fifth-wheels just a few years old in RV parks with three window AC units running and supposedly at lower cost than when the heat pump worked.)
In Texas one might think that heat pumps would be ideal but people keep telling me that the RV heat pumps don't last.
So what has been your experience? Is there credibility to these warnings I'm getting?
