Which outcome occurs when an HVAC system refrigerant line develops a small leak near the evaporator fan?

💡 Explanation

When a leak occurs near the evaporator fan, evaporative cooling concentrates at the leak, causing ice formation at that point and progressive icing inward because of heat transfer reduction. Therefore, ice forms on the coil, rather than motor burn-out, contaminated air, or simple capacity reduction without direct evidence of ice formation first at the leak.
