What happens when AC evaporator goes bad?

When an AC evaporator goes bad, it can lead to reduced cooling efficiency, causing the system to struggle to maintain the desired temperature. Symptoms may include warm air blowing from the vents, increased humidity levels, and potential leaks due to condensate buildup. In some cases, a malfunctioning evaporator can also lead to unusual noises or odors. If not addressed, it may cause further damage to the AC system, resulting in costly repairs.
