What can an improperly sized HVAC unit cause?

An improperly sized HVAC unit can lead to short-cycling, decreased efficiency, and uneven temperatures because the system is either too large or too small for the space it is intended to condition.

When an HVAC unit is too large, it tends to cool or heat the space too quickly, causing it to turn on and off frequently in a process known as short-cycling. This not only leads to increased wear and tear on the system, potentially reducing its lifespan, but it also means the unit doesn't run long enough to properly dehumidify the air, especially in cooling mode.

Alternatively, if the unit is too small, it struggles to reach the desired temperature, resulting in longer run times and inadequate heating or cooling throughout the space. This can create significant temperature disparities, leaving some areas too warm or too cold.

In summary, the consequences of an improperly sized HVAC system manifest in various performance issues, leading to discomfort, inefficiency, and increased operational costs.
