For a 13 SEER unit, what is the condenser split temperature compared to that of an 8-10 SEER unit?

The correct answer reflects the typical relationship between the efficiency rating of air conditioning units and their condenser split temperatures. A Seasonal Energy Efficiency Ratio (SEER) of 13 indicates a more efficient unit compared to the 8-10 SEER range. As efficiency increases, the condenser split temperature—the difference between the refrigerant temperature in the condenser and the outdoor air temperature—also tends to increase.

In this context, a 20° split is commonly associated with a 13 SEER unit. This means that the 13 SEER unit can maintain a lower refrigerant temperature, resulting in a greater temperature difference than what is observed in lower SEER units. In contrast, units with SEER ratings in the 8-10 range typically have a higher condenser split temperature, often around 10-15°.

Therefore, the understanding of these efficiencies and the corresponding condenser splits aids in evaluating system performance, emphasizing the more effective heat exchange occurring in higher SEER units compared to their lower SEER counterparts.
