What is the effect of oversized A/C units on indoor comfort?

Oversized A/C units have a notable impact on indoor comfort primarily related to the issue of short cycling. When an air conditioning unit is too large for the space it is supposed to cool, it cools the area too quickly, causing it to reach the set temperature in a short amount of time. This rapid cooling leads to frequent on-and-off cycling, known as short cycling.

Short cycling is problematic because it prevents the system from running long enough to properly dehumidify the air. Air conditioning systems not only cool the air but also remove moisture from it during the cooling process, contributing to overall indoor comfort. When the unit shuts off too quickly, the moisture removal process is interrupted, resulting in higher humidity levels indoors. This can create an uncomfortable environment, making it feel clammy or muggy, even if the temperature is at a desirable level.

Understanding this dynamic is crucial as it highlights the importance of selecting the correctly sized A/C unit for a given space, ensuring both effective cooling and appropriate humidity control to maintain indoor comfort levels.
