Keeping this in view, how do I know if my AC coil is bad?
If the airflow feels weak or doesn't turn on right away, you might have a refrigerant leak. Other signs include warm air coming through the vents, hissing noises from the outdoor A/C unit, frozen evaporator coils on the outdoor unit, and unpleasant odors when you turn on the heating or cooling system.
