7/17/25 For job I performed a evaluation. The system had froze at so.e point on 7/16/25 but had not done again since then. I told the homeowner it is likely caused by airflow or refrigerant issues. Service to IAQ, need to order damper and schedule Zak to complete damper replacement and give estimates for sealing the system due to cool air leaks in the attic. Refrigerant was wnl, perfect 20 delta. I left the broken overheated damper open and unplugged to not cause airflow restrictions.
