Condensation Overflow

[andreas]

Any suggestions to this problem on a household AC problem?:

1) Condensation overflow
2) Drain has been checked & cleaned of crud. Continues to drip on floor and not from drain line.
3) Evaporator coils are freezing up
4) No problems in last 11 yrs, but given little attention

- Thanks, Andreas

your problem sounds like it is related to the airflow.

poor airflow will cause freezing of the evaporator and sometimes airflow can affect your drain.

11 years of little attention usually causes this.

low air flow and low refrigerant charge are the usual culprits.
