I would love to see all about ductless A/C units. I have a 60s era apartment/co-op and while I've resigned myself to baseboard heating, I refuse to accept in-wall A/C. LOUD, thermostat-less and ugly, I'm ready to trash mine for something better. Ductless A/C is all over Europe where their buildings are much older and installing ductwork isn't an option. What's the cost? Contractors? How do I cover up that hole? Etc etc etc..!
