    We have a client and his two indoor units are sweating back the outdoor unit is in his garage and the heat his going nowhere the temp in there is 52 degrees would this cause the indoor units to start sweating ? The trouble is there is no where to extract the hot air

    His garage has walls so there is somewhere to get rid of the heat.

    52C is is way above the design operating conditions I'm sure.

    There is nowhere to take the heat as both sides are garage and the front of garage goes into underground drive

    You have to dump internal heat in place where the refrigerant can turns back in liquid form, otherwise system will not work properly, As mentioned by Mr. Brian arrange to vent it at other level, if possible try to fix a high speed extract fan to remove air from the area.

    This is underground garage so it impossible to vent the air

    The underground drive is like another sealed area

    Is it possible to convert to a water cooled condeser, heat exchanger? No way will it work if you cannot get rid of the heat from the refrigerant, best of luck to you.
