Which outcome arises when an HVAC system evaporator's frost layer becomes overly thick?

💡 Explanation

When a thick frost layer forms, thermal insulation occurs because frost impedes heat transfer from the air to the evaporator coil, reducing the system's ability to absorb heat. Therefore, cooling capacity deceases, rather than increased efficiency, refrigerant indications, or system overheating, which involve alternate failures.
