Which outcome occurs when non-condensable gases accumulate inside an HVAC evaporator?

💡 Explanation

When non-condensable gases such as air accumulate, they displace refrigerant inside the evaporator, limiting the area available for heat absorption, therefore decreasing the system's ability to cool. Therefore reduced cooling capacity results, rather than excess power usage, subcooling or superheat increases whose causes differ fundamentally.
