I have a three bedroom, 2 story townhouse (and a 2/3 finished basement) with electric baseboard heating. I am tired of window air conditioners. With three upstairs, we can usually get the whole house cool. But, they block the windows. One of them needs repair and one started making a chugga chugga type noise. It isn't making that noise right now.

I'm thinking of getting ductless air conditioning. Does anyone have experience with ductless air conditioning? What should I be looking for? What are the gotchas?
