First time poster. I participate at the Fine Homebuilding forum, and they suggested I ask my question here.
I am a remodeler in San Antonio. I am working with a client on the finishout of a condo unit. We are one of the first in the building so there's some options available. It's a multi-story building, we are on the third floor. The first and second floors are bigger, so there is a roof over the second floor. Every apartment will have its own a/c units. The building archy wants all of the units placed on the second floor roof. The problem is that there will be a couple right outside my clients bedroom window and living room window. The windows are single pane glass and can't be changed because they are historical.
The west side of the third floor has no windows, it's all brick. So we have suggested to the archy that all the a/c units be placed on the west side to keep the noise out of the bedroom. And my client has offered to pay the additional cost of the longer freon and electrical lines. The archy says no, the freon lines will be too long.
The building is requiring that all the units be Trane XB, XR, or XL. The vertical distance will not change. So the worst case will be the first floor units, which will have a vertical rise of about 25 ft. The distance across the building will be about 75 feet, so the freon lines could be as much as 100 ft long. Is that too long? Where can I findd some definitive information? I looked at the Trane website but could not find any technical info, just lots of pretty pictures.
