    A/C advice for one unit in a 400 unit brick condo tower

    I am combining apartments in a building from 1958. There are through the wall units (24" x 14.5") running on 115v.

    I would like to divide one room into two, but the new second room wouldn't have a hole in the wall, and I can't cut one. I am trying to figure out my options.

    I am wondering if I could use some kind of internal self-contained unit like they use in computer rooms to create central air conditioning and vent out my existing hole....

    Or use an against the wall internal self contained unit, if there is such a thing...

    Or get some kind of very powerful through the wall unit and duct off a bit of it.

    Or any other solution. Any ideas?

    Also, I have seen "mini ptac" units that look just like through the wall units from Amana and Carrier. What is the difference between an mini ptac unit and a through the wall unit?

    Thanks!!

    I would go with a ductless wall unit is all you would need is a 1 1/2" hole to run your lines and electrical outside to a condenser.

    Bet his condo association won't allow it.

    How many times must one fix something before it is fixed?

    These guys work pretty good, only thing is you will have to be near a window to vent the condenser.

    If you go with a portable, and that may be the only option for you, make sure it is a 2 pipe unit where one hose brings in air to the unit. The 1 pipe, exhaust only, can cause so much infiltration, that it really is doing nothing more than cooling the outdoor air that it sucks in.
