    Okay.

    Now I'm guessing that:

    1. Your current unit is a water-source heat pump and your condo building supplies water for the condensing coil through a recirculating loop to a cooling tower somewhere, possibly the roof?

    Or

    2. Your HP has a condensing unit on the roof?

    Or

    3. Your unit is merely a fan coil connected to a 4-pipe chilled/heated water system?

    OR

    4. Since its at the external wall, your current unit is a PTHP such as a Marvaire Scholar or Bard Qtec; having a grille on the outside wall for the condenser air inlet and outlet.

    Not that any of these will necessarily assist in providing options for another unit, but inquiring minds want to know; do you know which of these is correct?

    Thanks for the patience with me. I believe it would be number 4. There is a grill on the outside wall.

    Okay, now we know how you're cooling/heating currently.

    If you really want to go ahead with what you have in mind, the best bet is probably the unit to which you originally referred.

    In the States, Lowes and Home Depot carry a similar brand. As someone mention in an earlier post you would need a piece of plywood or something similar with holes to attach the condenser air vents (like dryer vent hoses). Plywood cut just wide and tall enough to fit between your sliding door and the jamb.

    Don't know how this is going to fly with your HOA. Good luck.

    Also you have to do something with the condensate water. Emptying a pan every couple of hours will get tiresome.

    Unico makes a system which works that way. And they are made in North America. I buy their equipment fairly often.

    Or you could do what I did when going head-to-head with the condo association nazi's. Just keep buying more condos until you can vote the disagreeable idiots off the board of trustees or directors. Then vote in someone who will work with you - like yourself - and change the rules.

    Essentially, instead of have a large condenser outside, you only need to drill two small holes on the external wall.

    I have small heating/requirement, probably below 20000BTU, and I need cooling for like a week every year.

    The question is, is such system available in North America? Anyone with experience in that?

    Thanks.

    This is the Toronto store.

    Don't know any of the brands except for Honeywell, but that doesn't mean they're not good. I believe some dispose of the condensate water somehow. Check with the personnel in the store.

    Use a pump to pump it out through 1/4" or so plastic tubing. Or if it's a water cooled unit, put it on the counter and let gravity do the work.

    Do measure the tap water temperature during the peak of summer. If it's still reasonably low (70F or less), a car radiator and box fan would be a cheap and efficient way to get A/C.

    This post revived my memory. I don't know if this even applies to shaousc's problem but I was sent to a house in the 70's and installed a Lennox unit where the condenser was in the attic and fit between studs in the outside wall. Only one I had seen.
    Slick though. Nice solution for when nothing else will work. I don't know if they make them anymore.
    I also remember spilling a gallon of white paint on their black roof while painting the trim. But hey, gotta expect apprentices to screw up right?

    The Olympia Splendid unit is an interesting concept. Needs an outside wall. My question is if the compressor is in the house, how noisy is it??

    The second one that is UK uses domestic water for a sink/source. More flexible in placement perhaps, but will be 200V 50Hz and not 208V 60Hz as used in N America...

    i was selling this ac units in Italy, many years ago, they work, and they work fine, not the quieter, but maybe things changed after all this years.
    The Olympia Splendid is been on the market for a long time. we have a lot of historical buildings Italy, and a condenser outside is not well accepted, some time not even an option, period. So welcome to this kind of systems, here in US, should be less problematic, less regulations and not too many bricks LOL.
    When you have to make holes in drywall or wood its easy. We have Bricks everywhere in italy even inside the house, to divide rooms, bricks and stucco or plaster.
    The way this ac work is simple, condenser and evaporator coil inside the housing, condenser get cooled from air coming from outside, air intake, and blowed outside from air discharge.
    Thats why you need two holes, this system work like magic, trust me, the only thing is that you cannot get a 5 tons system, as far as i remember, but i can be wrong. Anyway, my opinion is 2 thumbs up.
