What is a potential consequence of improperly sized HVAC equipment?

When HVAC equipment is improperly sized, the most significant consequence is increased energy costs and system strain. Properly sized equipment is essential for efficient operation. When an HVAC system is too small, it has to work harder to meet the heating or cooling demand, leading to frequent cycling on and off. This excessive operation results in higher energy consumption, ultimately causing an increase in utility bills. Additionally, the strain placed on the system can lead to a higher likelihood of breakdowns and a shorter lifespan for the components, as they are not designed to handle the continuous workload.

Conversely, if the equipment is oversized, it can cool or heat a space too quickly, preventing adequate air circulation and dehumidification, which ultimately affects comfort levels and indoor air quality. This sizing issue can also lead to frequent cycling, much like an undersized system, thereby straining the components. Thus, the potential consequence of improperly sized HVAC equipment primarily relates to energy inefficiency and unnecessary wear on the system.
