An air conditioning system that is oversized will most likely result in what issue?

An oversized air conditioning system will most likely result in insufficient de-humidification. When an air conditioning unit is oversized, it cools the space too quickly, causing it to cycle on and off more frequently. This short cycling limits the amount of time the system operates in a mode where it effectively removes humidity from the air.

De-humidification occurs when the system runs for an extended period, allowing for more moisture to be extracted from the air. However, because the oversized system reaches the desired temperature too rapidly, it does not run long enough to adequately remove moisture. As a result, the indoor environment can feel uncomfortable, as the humidity levels may remain high despite the temperature being cooled effectively.

This is a common issue in HVAC design, where proper load calculations and equipment sizing are critical for maintaining both comfort and efficiency in cooling systems.
