Which outcome occurs when an HVAC evaporator coil's airflow becomes restricted by accumulated dust?

💡 Explanation

When airflow is reduced, diminished heat transfer reduces evaporation, leading to less refrigerant phase change because latent heat extraction is limited. Therefore decreased cooling capacity results, rather than compressor issues, overcharge, or improved efficiency which require different thermal conditions or system changes.
