2023 Fall Check Up PCSA Prepaid Cleaned ice machine. Cleaned flame sensor. Checked wire connections. No CO detected. Replaced filters. All 3 systems were operating normally. Pastor had us look at systems for east and west Classrooms off the Fellowship Hall. West System had a bad thermostat that would shut off the AC. Replaced thermostat. System may need inspected after it’s had a chance to thaw. East System appears to be operating normally. Could be a programming issue with the thermostat but it appears to be operating normally. Noticed several wires going to the outdoor coils heavily damaged by weed trimmer. Sealed wires going to units and secured them to copper line sets.
