My MIL doesn't have ducts and therefore no central A/C. She's like to have me put a window unit on her 1st floor but the only windows that aren't sliding doors are an inside width of only 19 inches. She couldn't find narrower than 21 inches at HD and my internet search is only pulling up a/c units for small rooms.
Her other thought is a free standing unit that vents with a dryer hose like things.
Any thoughts on the effectness of this type of unit, or where to find a narrow width a/c unit would be appreciated!
Thanks,
Jeremy
