A condenser operates most efficiently at temperatures that allow for optimal heat exchange between the refrigerant and the surrounding environment. The efficiency of a condenser is largely influenced by the temperature difference between the refrigerant and the ambient air or cooling medium.

In general, a condenser should operate at a temperature that maximizes the heat rejection process while minimizing the energy required for the compressor to maintain system pressures. At 95°F, the condenser temperature strikes a good balance, where the refrigerant can adequately release heat without excessive energy use or pressure on the compressor.

Operating the condenser at higher temperatures, such as 100°F or beyond, can lead to increased pressures in the system, which makes the compressor work harder, reducing overall efficiency. Lower temperatures, like 75°F or 85°F, may not provide enough temperature difference for effective heat exchange under typical operational conditions, making 95°F the most efficient operating temperature for the condenser in this scenario.
