I have a rental property--- it's an older house--with one Apt. on first floor and another Apt. on second floor. Each Apt. has separate electric meters. The second floor Apt has 3 bedrooms and a living room. Currently, there is a window AC in the Living Room and a window AC in each of two bedrooms. THE 3rd BEDROOM IS WITHOUT AC. Unlike the Living room and the other two bedroom (that each have 2 windows), this bedroom has only one window--I can't put window AC in it for local fire code reasons (window must be unabstructed for fire escape reasons). So, with the living room and two bedrooms, I can cool those areas with a $300.00 window unit (for each area). However, with that 3rd bedroom, I can not simply install a window unit---- ALSO, for a lot of reasons, I can't cut a hole in an exterior wall of that 3rd bedroom and slide a wall AC into it. NOTE: there is a big attic above this bedroom---also, there is an outside wall That I could slide a wall AC unit into, BUT that exterior wall is in the bedroom's Closet!! Now, if there was such an AC system where I could put the unit in the closet wall---and pipe the cool air through the 2 foot deep closet to the bedroom---then great! ---I would get that system. OTHER FACTORS: I am aware that I could put an "cooling air handler" in the atic, and cool the bedroom by piping the cool air down from the bedroom ceiling --this approach would cost $2500.00+ (just to cool one bedroom)! Also, I am aware of mini split systems ---again $$$$ to cool one bedroom. QUESTION: Are there any suggestion of how I could cool that one bedroom and still keep the cost below $900.00? ---I would appreciate your help. ---Jaes.
