Through the wall AC Units

[Eric Gutierrez]

Hello,

I have a couple properties that have boilers so adding AC is a bit tricky.  I'm not a huge fan of window units for security reasons & I commonly see window units installed incorrectly so they wont drain the condensation out well.  I've even seen people set a window AC on a kitchen table.  

Anyways, I've gotten a couple estimates on mini splits and while I love the idea of them they are $$$.  I'm trying to think through various ways of getting AC into the units (even if it isn't an ideal setup.)  I'm contemplating either putting in a mini split with 1 head rather than multiple or possibly just putting through the wall AC units in the living room/dining room areas where it would help the bedrooms out.  I realize neither of these will be an ideal solution.  Anyone installed or had installed through the wall units?  What did they cost?  Do they actually last?
