What can happen if the HVAC system is oversized for a space?

When an HVAC system is oversized for a space, it can lead to increased energy bills. This occurs because an oversized unit will cycle on and off frequently rather than running continuously. This short cycling leads to inefficient energy usage, as the system spends more time starting up and shutting down instead of maintaining a consistent operation that is energy efficient.

Additionally, an oversized system may not effectively dehumidify the air, as it may cool the space too quickly without adequately controlling humidity levels. This can result in discomfort for occupants and can lead to further inefficiencies in energy use.

Other options reflect outcomes that typically do not occur with an oversized system. Uniform temperature distribution may actually be compromised, as rapid cycling can create hot and cold spots in the space. Similarly, a longer equipment lifespan is generally associated with properly sized systems that run efficiently, while an oversized system could experience more wear from frequent starts and stops. Finally, improved comfort levels generally result from appropriate sizing and proper humidity control, which is often lacking in oversized units.
