What is the temperature limit for ordinary home air conditioners to work?

If the outside air is the same temp as the condenser, the system can't work. Maybe liquid sodium air-conditioners will be needed in places like the Persian Gulf states.

    There are two choices for a condenser being used in a very hot place.  Incease the surface area of the condenser or opt for a cooling tower to provide the condensing of the refrigerant.  You can even use a combination of the two in some circumstances .

    Well-made and well-designed air conditioners employing the usual refrigerants can handle external (ambient) temps well above 100F, so there is no need to employ alternative refrigerants.  However, there is truth to your statement that not all "ordinary home A/C units" are designed to work efficiently at such higher temperatures, and units can lose efficiency if not maintained so lose ability to generate the more extreme temps in the condenser that would be required for high external ambient air temps.
