The windows are double-hung (they slide open vertically). To reduce traffic noise, I'm adding interior windows. These will open by sliding horizontally.
I don't want to get window AC units because the interior windows would have to be completely open when the units were in use. Also, the rooms, which are too large for low-profile window units, have river views. I'd rather not sacrifice the views in any room except the kitchen.
The co-op board probably won't let me install thru-the-wall units.
I'd like to cool the 180 sq ft kitchen, 253 sq ft dining room (which I'll use as a home office), 318 sq ft living room, 253 sq ft master bedroom, and 209 sq ft second bedroom, a total of 1213 sq ft. The ceilings are nine feet, with 1-foot-deep beams. All rooms have Western exposure except the second bedroom, which has Eastern exposure.
I wonder what you think of these options. Please see floorplan at http://members.aol.com/kirtaylor/FloorPlan.gif
1) Install two condensers in the kitchen window beside the washer-dryer. Drop the ceiling there to accomodate an air handler. Duct the air handler out to the home office.
Put another air handler in the closets between the two bedrooms. Duct it to the living room.
Run the returns through the adjacent second bedroom and hallway closets, across the hallway, and back to the condenser through the kitchen cabinets.
I've been told that this kitchen window isn't big enough for ductless condensers (e.g. Mr. Slim), but it is big enough for two ducted condensers.
2) Get portable units. The interior windows would still have to be partially open for the vent, but not all the way. The portables are easily removed. I would want the kind that doesn't require water pan emptying.
Any help would be greatly appreciated!
