What is the consequence of having oversized HVAC equipment?

Choosing oversized HVAC equipment leads to short cycling and inefficient operation, which is a significant consequence. When an HVAC system is larger than necessary for the space it serves, it heats or cools the area too quickly, resulting in the system frequently turning on and off, a phenomenon known as short cycling. This behavior not only increases energy consumption but also places undue stress on the system's components, potentially causing them to wear out faster.

In contrast, a properly sized HVAC system operates more efficiently, providing consistent comfort without unnecessary energy expenditure. This efficiency contributes to better overall air quality, as the system has adequate runtime to filter air effectively and manage humidity levels. Therefore, understanding the ramifications of equipment sizing highlights the importance of proper load calculations during system installation to ensure optimal performance and longevity.
