8 - 12. COD. Spoke to Christina. REQ DAVID ONLY. David was out in November, she said he should know what the issue is and was told to call back if it was happening again. Panel says no airflow, but temp is 70, panel says it's 80 something. Said she needs a filter change as well. Quoted $158 for diagnostic. Looks like we put in a 4 zone zoning board in 2023.
