While it is as cold as a witch's elbow, I'm thinking about the summer ac 
season.   I'd like to do away with the window units in the bedrooms of a 
small ranch house (one bedroom is the shack).

Since there is no duct work in the house, I'm considering  one of the 
mini split units.  Known by different names,  it's basically a multi 
zone system with an outside unit and each room having it's own  air 
handler and controls.   The inside and outside units are connected by 
power and control wires and refrigerant lines, passing through small 
holes into the house.

Wondering about any RFI problems on HF running up to a KW.  Any info 
would be welcome.
