> so, how much would it cost to put in a ductless in the bedrooms? I didn't install central air either, it's basic split units (probably the precursors to your moon rocket cooler) where the only thing you really need to get through the walls are relatively thin coolant lines that run to the outside heat exchangers. It's about 600€ per unit, I'd say. The modern ones are pretty quiet as well. The nice thing I noticed about them is they have an efficiency of around 2.6 - meaning that for every Watt you put in, around 2.6 Watts of energy are being moved, both in or out. Obviously, that subject to some adjustment depending on the temperature gradient, but it's way more efficient than the electrical heating that was installed in my bungalow before. > I have not seen the electric bill yet. I remember an episode of "Married with Children", where Al brings home a ancient German AC that was made by the Nazis or something, and when they plugged it in the entire neighborhood lost power. That's what I picture is in your house ;)
